Abstract
Studies on the interactions between ligands and proteins provide insights into how a possible medication alters the structures and activities of the target or carrier proteins. The natural flavonoid aglycone Chrysin (CHR) has demonstrated anti-inflammatory, antioxidant, antiapoptotic, neuroprotective, and antineoplastic effects, both in vitro and in vivo. In this work, we investigated the impact of CHR binding on the as-yet-unexplored conformation, dynamics, and unfolding mechanism of human serum albumin (HSA). We determined CHR binding to HSA domain-II with the association constant (Ka) of 2.70 ± 0.21 × 105 M-1. The urea-induced sequential unfolding mechanism of HSA was used to elucidate the debatable binding location of CHR. CHR binding induced both secondary and tertiary structural alterations in the protein as studied by far-UV circular dichroism and intrinsic fluorescence spectroscopy. Red edge excitation shift (REES) indicated a decrease in conformational dynamics of the protein on the complex formation. This suggested an ordered compact and spatial arrangement of the CHR-boundmolecule. The binding of CHR was found to significantly modulate the urea-induced unfolding pathway of HSA. Urea-induced unfolding pathway of HSA became a two-state process (N-U) from a three-state process (N-I-U). The interaction of CHR is found to increase the thermal stability of the protein by ∼4 °C. This study focuses on the fundamental sciences and demonstrates how prospective medication compounds can alter the dynamics and stability of protein structure.

Abstract
Chrysin is a flavonoid drug with numerous therapeutic activities. It suffers from low intestinal absorption owing to its hydrophobicity. Therefore, the aim of this study is to exploit the efficient technique of nanosuspension (NSP) to formulate chrysin-NSP coated with tannic acid (TA) to improve the solubility and anti-schizophrenic activity of chrysin. A 23 full factorial design was constructed where the independent factors were type of polymer, surfactant concentration (0.5 or 1 %) and the aqueous phase volume (5 or 15 mL), while the dependent responses were the particle size (PS) of the obtained formulation as well as the % chrysin dissolved after 2 h (Q2h). The optimum formulation (NSP-4) composed of 1 % PEG 400 and 1 % Cremophor RH40 in 15 mL aqueous phase. It achieved a PS and Q2h values of 108.00 nm and 38.77 %, respectively. NSP-4 was then coated with TA (TA-coated NSP-4) for further enhancement of chrysin solubility. TA-coated NSP-4 revealed PS and zeta potential values of 150 ± 14 nm and -32.54 ± 2.45 mV, respectively. After 6 h, chrysin dissolved % were 53.97 and 80.22 for uncoated NSP-4 and TA-coated NSP-4, respectively, compared with only 9.47 for free chrysin. The developed formulations and free chrysin were assessed regarding their effect on schizophrenia induced in mice by cuprizone (CPZ). Treatment with the developed formulations and free chrysin ameliorated demyelination and behavioral deficit induced by CPZ via elevating MBP and PI3K/PKC activities as well as reducing GFAP expression levels. The developed formulations and free chrysin inhibited Galactin-3 and TGF-β expressions and stimulated GST antioxidant enzyme. Furthermore, they maintained the balances in glutamatergic and dopaminergic neurotransmission via modulation on neuregulin-1 and alleviated nuclear pyknosis and degeneration in the neurons. The order of activity was: TA-coated NSP-4 > NSP-4 > free chrysin.

Abstract
Blood transfusion-requiring diseases such as sickle cell anemia and thalassemia are characterized by an imbalance between iron intake and excretion, resulting in an iron overload (IOL) disorder. Hepatotoxicity is prevalent under the IOL disorder because of the associated hepatocellular redox and inflammatory perturbation. The current work was devoted to investigate the potential protection against the IOL-associated hepatotoxicity using chrysin, a naturally-occurring flavone. IOL model was created in male Wistar rats by intraperitoneal injection of 100 mg/kg elemental iron subdivided on five equal injections; one injection was applied every other day over ten days. Chrysin was administered in a daily dose of 50 mg/kg over the ten-day iron treatment period. On day eleven, blood and liver samples were collected and subjected to histopathological, biochemical, and molecular investigations. Chrysin suppressed the IOL-induced hepatocellular damage as revealed by decreased serum activity of the intracellular liver enzymes and improved liver histological picture. Oxidative damage biomarkers, and pro-inflammatory cytokines were significantly suppressed. Mechanistically, the levels of the redox and inflammation-controlling proteins SIRT1 and PPARγ were efficiently up-regulated. The liver iron load, NLRP3 inflammasome activation, and NF-κB acetylation and nuclear shift were significantly suppressed in the iron-intoxicated rats. Equally important, the level of the antioxidant protein Nrf2 and its target HO-1 were up-regulated. In addition, chrysin significantly ameliorated the IOL-induced apoptosis as indicated by reduction in caspase-3 activity and modulation of BAX and Bcl2 protein abundance. Together, these findings highlight the alleviating activity of chrysin against the IOL-associated hepatotoxicity and shed light on the role of SIRT1, NLRP3 inflammasome, and Nrf2 signaling as potential contributing molecular mechanisms.

Abstract
Chrysin is a natural flavonoid with powerful neuroprotective capacity. Cerebral ischemia/reperfusion injury (CIRI) is associated with oxidative stress and ferroptosis. Hypoxia-inducible factor 1α (HIF-1α) and ceruloplasmin (CP) are the critical targets for oxidation reactions and iron transport. But the regulatory mechanism between them is still unclear. Transient middle cerebral artery occlusion (tMCAO) model in rats and oxygen and glucose deprivation/re-oxygenation (OGD/R) model in PC12 cells were applied. Pathological tissue staining and biochemical kit were used to evaluate the effect of chrysin. The relationship between HIF-1α and CP was verified by transcriptomics, qRT-PCR and Western blot. In CIRI, HIF-1α/CP loop was discovered to be the regulatory pathway of ferroptosis. CIRI led to activation and nuclear translocation of HIF-1α, which promoted CP transcription and translation, and downstream ferroptosis. Inhibition of HIF-1α had opposite effect on CP and ferroptosis regulation. Overexpression of CP increased the expression of HIF-1α, nevertheless, inhibited the nuclear translocation of HIF-1α and alleviated CIRI. Silencing CP promoted HIF-1α elevation in nucleus and aggravated CIRI. Mechanistically, chrysin restrained HIF-1α nuclear translocation, thereby inhibiting CP transcription and translation, which in turn reduced downstream HIF-1α expression and mitigated ferroptosis in CIRI. Our results highlight chrysin restrains ferroptosis in CIRI through HIF-1α/CP loop.

Abstract
In this study, various concentrations of chrysin (chry) were loaded into polycaprolactone-chitosan (PCL-CTS) nanofibers to develop a potential wound dressing materials using electrospinning method. The structural composition and the morphology of the produced PCL-CTS5, PCL-CTS10 and PCL-CTS15 were analyzed by FE-SEM and FTIR, respectively. By increasing the amount of chry, the average diameter of the nanofibres was also increased to 191 ± 65 nm, 203 ± 72 nm, and 313 ± 69 nm for PCL-CTS5, PCL-CTS10, and PCL-CTS15, respectively. Moreover, the physicochemical characteristics and biological properties of synthesized nanofibers such as tensile testing, in-vitro drug release, porosity, decomposition rate, water absorption rate, water vapor permeability rate, cell viability, antioxidant and antibacterial activity were evaluated. By using Korsmeyer-Peppas and Higuchi kinetic models, the chry release mechanism in all nanofibers was studied in PBS solution, which suggested a Fick's diffusion. In-vitro antioxidant experiments by DPPH assay indicated 24, 43, 61 and 78 % free radical scavenging activity for PCL-CTS, PCL-CTS5, PCL-CTS10 and PCL-CTS15. In-vitro antibacterial examination showed that chry-loaded nanofibers had high antibacterial activity in which were comparable with the standard reagents. In-vitro cytotoxicity results obtained by MTT assay indicated a desired cytocompatibility towards fibroblast cells.

Abstract
Choroidal neovascularization (CNV) is a devastating pathology of numerous ocular diseases, such as wet age-related macular degeneration (wAMD), which causes irreversible vision loss. Although anti-vascular endothelial growth factor (VEGF) therapy has been widely used, poor response or no response still exists in some cases, suggesting that there are other components involved in the angiogenic process. Therefore, the underlying mechanism needs to be clarified and new target of anti-angiogenic therapy is urgently needed. It has been demonstrated that damaged retinal pigment epithelium (RPE) cells can activate inflammasome, driving a degenerative tissue environment and an enhanced pro-angiogenic response, which implies that RPE dysfunction may be a hallmark of the pathogenesis. Previously, we have shown that DNA damage can induce RPE dysfunction, triggering senescence-associated secretory phenotype (SASP) and local inflammation. In this study, we identify that chrysin can reduce DNA damage, especially telomere erosion in vitro, thus compromise the dysfunction of RPE and the decreased expression of SASP factor. Importantly, we find that DNA damage of RPE cells is remarkable in laser-induced CNV lesion, resulting in inflammatory response, which can be ameliorated by chrysin, mainly through IL-17 signaling pathway and its downstream signal transducer and activator of transcription 3 (STAT3) activities. In summary, our results indicate the interplay between DNA damage, perturbed RPE homeostasis, inflammatory response and angiogenesis in laser-induced CNV, and more importantly, chrysin may be an effective therapeutic supplement for CNV.

Abstract
BACKGROUND The chance of contracting significant diseases increases due to an unhealthy and contemporary lifestyle. Chrysin is a flavonoid of the flavone class in numerous plants, including Passiflora and Pelargonium. Chrysin has long been used to treat a variety of illnesses. Chrysin, an essential flavonoid, has many pharmacological actions, including anticancer, antiviral, anti-inflammatory, anti-arthritic, depressive, hypolipidemic, hepatoprotective, and nephroprotective activity. PURPOSE This explorative review was commenced to provide a holistic review of flavonoids confirming that Chrysin has a therapeutic potential on the liver and kidney and reduces the hepatotoxicity and nephrotoxicity induced by diverse toxicants, which can be helpful for the toxicologists, pharmacologists, and chemists to develop new safer pharmaceutical products with chrysin and other toxicants. STUDY DESIGN The most relevant studies that were well-explained and fit the chosen topic best were picked. The achieved information was analyzed to determine the outcome by screening sources by title, abstract, and whole work. Between themselves, the writers decided on the studies to be considered. The necessary details were systematically organized into titles and subtitles and compressively discussed. METHOD The information presented in this review is obtained using targeted searches on several online platforms, including Google Scholar, Scifinder, PubMed, Science Direct, ACS publications, and Wiley Online Library. The works were chosen based on the inclusion criteria agreed upon by all authors. RESULTS Chrysin is a promising bioactive flavonoid with significant health benefits, and its synthetic replacements are being utilized as pharmaceuticals to treat various diseases. Findings revealed that Chrysin exhibits hepatoprotective actions against several hepatotoxicants like 2,3,7,8 tetrachlorodibenzo- p-dioxin, carbon tetrachloride (CCl4), cisplatin, and others by lowering the levels of liver toxicity biomarkers and enhancing antioxidant levels. Additionally, chrysin has potential nephroprotective properties against various nephrotoxicants, like Cisplatin, Doxorubicin, Paracetamol, Gentamicin, Streptazosin, and others by dropping kidney toxicity marker levels, reducing oxidative stress, and improving the antioxidant level. CONCLUSION According to this revised study, chrysin is a promising phytoconstituent that can be utilized as an alternate treatment for various medications that cause hepatotoxicity and nephrotoxicity. With active chrysin, several dosage forms targeting the liver and kidneys can be formulated.

Abstract
Chrysin (5,7-dihydroxyflavone, 6) and galangin 3-methyl ether (5,7-dihydroxy-3-methoxy flavone, 7) were obtained from the leaves of Oroxylum indicum (L.) Kurz in 4% and 6% yields, respectively. Both compounds could act as pan-histone deacetylase (HDAC) inhibitors. Structural modification of these lead compounds provided thirty-eight derivatives which were further tested as HDAC inhibitors. Compounds 6b, 6c, and 6q were the most potent derivatives with the IC50 values of 97.29 ± 0.63 μM, 91.71 ± 0.27 μM, and 96.87 ± 0.45 µM, respectively. Molecular docking study indicated the selectivity of these three compounds toward HDAC8 and the test against HDAC8 showed IC50 values in the same micromolar range. All three compounds were further evaluated for the anti-proliferative activity against HeLa and A549 cell lines. Compound 6q exhibited the best activity against HeLa cell line with the IC50 value of 13.91 ± 0.34 μM. Moreover, 6q was able to increase the acetylation level of histone H3. These promising HDAC inhibitors deserve investigation as chemotherapeutic agents for treating cancer.

Abstract
BACKGROUND This study was performed to evaluate the protective effects of chrysin (CH) on metabolic impairment and pancreatic injury caused by sub-chronic chlorpyrifos (CPF) intoxication in male rats. METHODS Forty male Wistar rats were randomly allocated into five groups (n=8). Intraperitoneal injections of chrysin (12.5, 25 and 50 mg/kg for 45 days) and CPF (10 mg/kg for 45 days) gavage were performed. Present findings indicated that the serum levels of glucose, total cholesterol, and lowdensity lipoprotein-cholesterol, as well as body weight, were increased in the CPF-exposed group. RESULTS It was also found that CPF decreased superoxide dismutase activity as well as increased malondialdehyde and nitric oxide levels in the pancreatic tissue of exposed animals. Histopathological examination also confirmed the toxic effects of CPF on pancreatic tissue as mostly evidenced by infiltration of inflammatory cells and necrosis. CH (50 mg/kg) decreased blood glucose concentration (p < 0.05), TG (p < 0.05), and LDL-C in CPF-exposed animals. CH decreased the pancreas levels of MDA in all treated CPF-exposed groups versus the non-treated CPF-exposed group (p < 0.05, p < 0.001, p < 0.001, respectively). A significant difference was not seen in the NO and MDA levels and SOD activity between CH-treated (50 mg/kg) animals exposed to CPF and controls. A significant difference was not seen in the NO and MDA levels and SOD activity between CHtreated (50 mg/kg) animals exposed to CPF and controls. CONCLUSION A significant difference was not seen in the NO and MDA levels and SOD activity between CH-treated (50 mg/kg) animals exposed to CPF and controls. In conclusion, CH could prevent initiate and progress of CPF-induced metabolic impairment by modulating oxidative stress in pancreatic tissue as a target organ of organophosphorus pesticides.

Abstract
Chrysin (CR) is a water-insoluble drug reported for different therapeutic effects. The microwave irradiation method was used in this study to create a multicomponent inclusion complex (CR-MC) containing CR (drug) and carrier hydroxyl propyl beta cyclodextrin (HP β CD) and L-arginine (LA). The prepared inclusion complex (CR-MC) was evaluated for dissolution study and results were compared with chrysin physical mixture (CR-PM). Further, the samples were assessed for infra-red (IR), nuclear magnetic resonance (NMR), differential scanning calorimeter (DSC), scanning electron microscope (SEM) and molecular docking. Finally, the cell viability, reactive oxygen species and flow cytometer studies were also assessed to check the potential of the prepared inclusion complex on the human primary glioblastoma cell line (U87-MG cell). The phase solubility findings revealed a stability constant (773 mol L-1) as well as a complexation efficiency of 0.027. The dissolution study displayed a significant increase in CR release from CR-MC (99.03 ± 0.39%) > CR-PM (70.58 ± 1.16%) > pure CR (35.29 ± 1.55%). NMR and IR spectral data revealed no interaction between CR and carriers. SEM and DSC study results revealed the conversion into amorphous form. The molecular docking results illustrated a high docking score, which supports the findings of complex formation. The cell viability, reactive oxygen species, and flow cytometry studies results showed enhanced activity from CR-MC against the tested human primary glioblastoma cell line. From the results it has been observed that chrysin solubility significantly increased after complexation and there in vitro activity also enhanced against cancer cell line.

Abstract
Background Ischemic preconditioning (IPC) is the utmost capable design to achieve protection over ischemia-reperfusion injury (I/R), but this phenomenon gets attenuated during various pathological conditions like diabetes. Chrysin exhibits cardioprotection in various experiments however, its therapeutic potential on IPC-mediated cardioprotection via PI3K-Akt-eNOS pathway in streptozotocin (STZ) triggered diabetes-challenged rat heart is yet to be assessed. For that reason, the experiment has been planned to investigate chrysin's effect on the cardioprotective action of IPC involving the PI3K-Akt-eNOS cascade in rat hearts challenged to diabetes. Methods The project was accomplished through means of absorbance studies for biochemical parameters, infarct size measurement (TTC stain) and coronary flow. Results The findings of the present study revealed that STZ drastically augmented the serum glucose level and the chrysin significantly reversed the IPC-stimulated increased coronary flow, nitrite release, and reduced LDH (lactate dehydrogenase), CK-MB (creatine kinase) activities as well as infarct size in diabetes-induced rat heart. Furthermore, chrysin also reversed the IPC-induced reduction in oxidative stress in an isolated Langendorff's perfused diabetic rat heart. Moreover, four episodes of preconditioning by either PI3K or eNOS inhibitor in chrysin-pretreated diabetic rat hearts significantly abolished the protective effect of chrysin. Conclusion Consequently, these observations suggested that chrysin increases the therapeutic efficiency of IPC in mitigating I/R injury via PI3K-Akt-eNOS signalling in diabetes-challenged rat hearts. Hence, chrysin could be a potential alternative option to IPC in diabetic rat hearts.

Abstract
Traumatic brain injury (TBI) is recognized as an important risk factor for cognitive deficits. The present study was designed to determine the potential neuroprotective effects of chrysin, a natural flavonoid compound, against TBI-induced spatial cognitive decline and the possible mechanisms involved. Oral administration of chrysin (25, 50, or 100 mg/kg/day) was initiated in rats immediately following the induction of the diffuse TBI model using the weight-dropping Marmarou model. Spatial cognitive ability, hippocampal synaptic plasticity, blood-brain barrier (BBB) permeability, brain water content, and histological changes were assessed at scheduled time points. The animals subjected to TBI exhibited spatial cognitive decline in the Morris water maze (MWM) test, which was accompanied by inhibition of hippocampal long-term potentiation (LTP) induction at the perforant path-dentate gyrus (PP-DG) synapses. Additionally, TBI caused BBB disruption, brain edema, and neuronal loss. Interestingly, treatment with chrysin (especially in the dose of 100 mg/kg) alleviated all the above-mentioned neuropathological changes related to TBI. The results provide evidence that chrysin improves TBI-induced spatial cognitive decline, which may be partly related to the amelioration of hippocampal synaptic dysfunction, alleviation of BBB disruption, reduction of brain edema, and prevention of neuronal loss.

Abstract
The study of inclusion complexes of Chrysin (ChR) with three forms of cyclodextrins (CDs) α-, β-, and γ-CD was accomplished to examine the stability of ChR inside the central cavities of CDs. The aim of study was to identify the most suitable form of CD to improve the hydro-solubility of poorly soluble ChR bioactive molecule. Microsecond timescale molecular dynamics (MD) simulations were performed on four inclusion complexes (α-CD/ChR, β-CD/ChR, and two conformations of γ-CD/ChR) to examine the dynamics of ChR inside the cavity of CDs. The first conformation of γ-CD/ChR inclusion complex (γ-CD1/ChR) was identified to possess the highest affinity between host and guest molecule on the basis of binding energy calculated by employing Molecular Mechanics Poisson-Boltzmann Surface Area (MM-PBSA) and umbrella sampling simulations. To further strengthen the claims of classical and biased MD studies, Our own N-layered Integrated molecular Orbital and Molecular mechanics (ONIOM) (wB97XD/6-311+g(d,p):pm7) calculations were performed on the selected inclusion complexes. The ONIOM based complexation energy reaffirmed that ChR had highest affinity for the γ-CD1 host molecule. Further, the non-covalent interaction analysis was conducted using Multiwfn software on QM-optimized inclusion complexes with wB97XD/6-311+G(d,p) model chemistry, revealing non-covalent interactions between ChR and CDs. This atomic level information helped us to gain better insights into critical atoms of ChR and CD that participated in intermolecular interactions and identify γ-CD as a suitable host molecule for improving the hydro-solubulity of ChR. The structural insights would help to derive new derivatives of γ-CD with better host capacity.

Abstract
AIMS Paclitaxel (Pax) is a chemotherapeutic drug from the taxane family that is used in the treatment of human cancer, including ovarian, breast, and non-small cell lung carcinoma. Chrysin (CR) has antioxidant, anti-inflammatory, anti-apoptotic, anti-diabetic, and anti-carcinogenic properties, as well as hepatoprotective and renoprotective activities. In the present study, we evaluated the protective effect of CR against Pax-induced hepatorenal toxicity on inflammation, apoptosis, antioxidant levels, oxidative DNA damage, and histopathology in rats. MATERIAL AND METHODS Thirty-five male Sprague-Dawley rats were divided into five groups (n = 7): Group I (normal control), Group II (CR alone at a dose of 50 mg/kg), Group III (Pax at a dose of 2 mg/kg), Group IV (Pax+CR 25), and Group V (Pax+CR 50). The expressions of apoptotic (Bax and Bcl-2) and antioxidant genes (SOD1, CAT, GPx3, and GST) were evaluated using RT-PCR from paraffin sections. Caspase 3, KIM-1, NF-kB, COX-2, and 8-OHdG were also determined by immunohistochemical examination. KEY FINDINGS The results revealed that Pax exposure caused hepatic and renal damage in rats, which was indicated by a significant elevation of caspase 3, Bax, KIM-1, NF-kB, COX-2, and 8-OHdG. However, there was a marked downregulation in the expressions of the Bcl-2, SOD1, CAT, GPx3, and GST genes. In contrast, rats given CR in combination showed better gene expression, histological structure, and immunohistochemical staining results. SIGNIFICANCE Consequently, CR exhibited the ability to reduce oxidative DNA damage, exert anti-apoptotic and anti-inflammatory properties, and mitigate the toxic effects of Pax-induced hepatorenal toxicity.

Abstract
In the present work, chrysin loaded bilosomes were formulated, characterized and evaluated to enhance the hepatoprotective activity of drug. Accordingly, chrysin loaded bilosomes were prepared by applying the thin film hydration method; also, fractional factorial design was used to optimize the production conditions of nanoformulations. The prepared formulations were subjected to different methods of characterization; then the hepatoprotective activity of the optimized one was evaluated in the CCl4 hepatointoxicated mice model. Optimized chrysin loaded bilosomes showed a spherical shape with a particle size of 232.97 ± 23 nm, the polydispersity index of 0.35 ± 0.01, the zeta potential of -44.5 ± 1.27 mv, the entrapment efficiency of 96.77 ± 0.18%, the drug loading % of 6.46 ± 0.01 and the release efficiency of 42.25 ± 1.04 during 48 h. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging assay demonstrated the superiority of the anti-oxidant potential of chrysin loaded bilosomes, as compared to pure chrysin. This was in agreement with histopathological investigations, showing significant improvement in serum hepatic biomarkers of CCl4 intoxicated mice treated with chrysin loaded bilosomes, as compared with free chrysin. These results, thus, showed the potential use of bilosomes to enhance the hepatoprotective activity of chrysin via oral administration.

Abstract
BACKGROUND Cadmium (Cd) is a strong toxic agent and causes serious damage to testicular tissues. Chrysin (CHR) is a natural flavonoid with many effective properties, especially antioxidant, anti-inflammatory and anti-apoptotic properties. The current study describes new evidence for the ameliorative effects of CHR on oxidative stress, apoptosis, autophagy and inflammation pathways in Cd-induced testicular tissue toxicity. METHODS Thirty-five male Wistar rats were divided into five groups, control, Cd, CHR, Cd + CHR25, and Cd + CHR50. Cd was administered alone at a dose of 25 mg/kg body weight or in combination with CHR 25 mg/kg and CHR 50 mg/kg for 7 days. Cd and CHR were administered orally. Biochemical, molecular, and histological methods were used to investigate inflammation, apoptosis, autophagy, and oxidant pathways in testicular tissue. RESULTS Cd increased lipid peroxidation, JAK-2/STAT-3 levels, inflammation-related NF-κB, TNF-α, IL-1β, IL-6, COX-2, and iNOS levels, AKT-2, FOXO1, Bax, Apaf-1 and Caspase-3 levels, autophagic Beclin-1, LC3A and LC3B. The Cd also caused a decrease in the activities of antioxidant enzymes and GSH levels, antiapoptotic Bcl-2 levels. CHR, on the other hand, had the opposite effect of all these Cd-induced changes. CONCLUSIONS Overall, the data of this study indicate that testicular damage associated with Cd toxicity could be ameliorated by CHR administration.

Abstract
BACKGROUND Chemotherapeutic agents are used to treat a wide range of cancer types, but they cause serious side effects which must be managed after treatment. Cyclophosphamide (CYP) is one of chemotherapeutic drugs that causes hemorrhagic cystitis (HC) induced by acrolein. OBJECTIVE The current investigation intended to uncover the role of chrysin (CHR) in CYP-induced HC in rats and explore the signaling pathway beyond this effect. ANALYSIS process: A single dose of CYP (200 mg/kg/IP) was injected, meanwhile CHR (25, 50 and 100 mg/kg, P.O) was administered respectively for 7 days prior to CYP administration and resume for 7 days afterwards. Urinary bladder tissue was then isolated from all rats to assess oxidative stress and inflammatory biomarkers. Moreover, histopathological examinations were performed. RESULTS Treatment with CHR showed a marked alleviation in oxidative stress biomarkers induced by CYP. Furthermore, CHR treatment presented a dose-dependent boost in the anti-inflammatory; IL-10 levels and a drop in the pro-inflammatory biomarkers; IL-1β, IL-6, and TNF-α. Additionally, stabilization of the PARP-1 protein expression was also detected thus preventing DNA damage. Similarly, CHR restored the urinary bladder cGMP levels. Notably, CHR treatment was accompanied with inhibition in NF-κB/p38-MAPK, NO/PARP-1 and STAT-3 signaling pathways inflammatory cascades. All these findings conformed with the histopathological examinations as well as iNOS immunostaining in the urinary bladder tissue. CONCLUSION Co-administration of CHR and CYP attained uro-protective therapeutic potential to guard against HC as well as spot the tangled mechanism of CHR in attenuating the HC induced by CYP.

Abstract
Induction of immunogenic cell death (ICD) is a promising strategy for cancer immunotherapy. Chrysin, which has potential anticancer effects, faces limitations in clinical applications due to its poor water solubility. This study aimed to formulate chrysin with PEG-poly(α-benzylcarboxylate-ε-caprolactone) (PBCL) nanoparticles (NPs) and assess their anticancer and ICD-inducing potency in melanoma cells, comparing with free chrysin. The co-solvent evaporation method was employed to develop chrysin-loaded NPs. UV spectroscopy, dynamic light scattering, and the dialysis bag method were used to evaluate the encapsulation efficiency (EE), particle size, polydispersity index (PDI), and drug release profile, respectively. The anticancer effects of the drugs were assessed using the MTT and trypan blue exclusion assays. Flow cytometry was employed to evaluate apoptosis and calreticulin (CRT) expression. ELISA and western blotting were used to detect heat shock protein 90 (HSP90), Annexin A1, GRP78 (Glucose-related protein78), and activated protein kinase R-like endoplasmic reticulum kinase (p-PERK). Chrysin-loaded PEG-PBCL NPs (chrysin-PEG-PBCL) showed an EE of 97 ± 1%. Chrysin-PEG-PBCL was 38.18 ± 3.96 nm in size, with a PDI being 0.62 ± 0.23. Chrysin-PEG-PBCL showed an initial burst release, followed by sustained release over 24 h. Chrysin-PEG-PBCL exhibited a significantly stronger anticancer effect in B16 cells. Chrysin-PEG-PBCL was found to be more potent in inducing apoptosis. Both free chrysin and chrysin NPs induced ICD as indicated by an increase in the levels of ICD biomarkers. Interestingly, chrysin NPs were found to be more potent inducers of ICD than the free drug. These findings demonstrate that chrysin and chrysin-PEG-PBCL NPs can induce ICD in B16 cells. PEG-PBCL NPs significantly enhanced the potency of chrysin in inducing ICD compared to its free form.

Abstract
In total, nine TPGS-b-PCL copolymers were synthesized employing distinct TPGS analogues (TPGS 2000, 3500, and 5000). In these copolymers, the length of the PCL chain varied according to the TPGS to PCL molecular weight ratio (1:1, 1:2, and 1:3). The formulation optimization was done by optimizing the drug to polymer ratio, encapsulation efficiency, drug loading, micelle diameter, and polydispersity index (PDI). TPGS3500-b-PCL7000 copolymer (TPGS to PCL ratio 1:2) with drug to polymer ratio 1:30 showed the best percentage encapsulation (63.50 ± 0.45 %) and drug loading (2.05 ± 0.07). The optimal micelle (CHR-M) diameter and PDI were determined to be 94.57 ± 13.40 nm and 0.16 ± 0.02, respectively. CHR-M showed slow release when compared with alcoholic solution of chrysin. Approximately 70.70 ± 6.4 % drug was released in 72 h. The CHR-M demonstrated considerably greater absorption in Hep G2 cells, which confirmed the reliability of the micellar carrier. The MTT assay results showed that the IC50 values for CHR-M were much lower after 24 and 48 h when compared to free chrysin. Therefore, CHR-M may be a viable carrier for active chrysin targeting with improved anticancer potential. Also, it could be a better alternative for the currently available treatment of hepatocellular carcinoma.

Abstract
Background Morus alba Linn, referred to as white mulberry, is a potential traditional medicine for diabetes and neuroprotection. Aim Isolation, characterization, development and evaluation of phytoconstituent based formulation for diabetic neuropathy. Material and methods The stem Bark of M. alba was peeled and subjected to extraction. A phytoconstituent was then isolated by column chromatography and characterized using Mass spectroscopy, FTIR, and NMR. The isolated phytoconstituent was used to formulate a nanoemulsion. Nanoemulsion was also characterized for viscosity, surface tension, refractive index, pH, and particle size. Selected nanoemulsion formulations were then tested for acute oral toxicity and diabetic neuropathy, including behavioral, hematological, histopathological, and biomarker examinations. Results The spectral analysis affirmed that the isolated compound was found to be chrysin. A nanoemulsion formulation was made using the chrysin and was characterized and found to be stable during the stability testing and fulfilled all other testing parameters. Then acute oral toxicity study of the formulations was found to be safe. Formulations were found to possess significant results against diabetic neuropathy in rats. Biomarkers were analyzed for their mechanistic involvement in reducing neuropathy in rats, and it was found that the oxidative pathway was considerably restored, suggesting that chrysin causes these effects via this pathway. Conclusions Results suggests that isolated phytoconstituent (chrysin) from the bark of Morus alba derived nanoemulsion has protective and beneficial effects by diminishing the oxidative damage against alloxan-induced diabetic neuropathy in rats.

Abstract
This study aimed to determine the potential protective effects of chrysin (CHR) on experimental cadmium (Cd)-induced lung toxicity in rats. To this end, rats were divided into five groups; Control, CHR, Cd, Cd + CHR25, Cd + CHR50. In the study, rats were treated with CHR (oral gavage, 25 mg/kg and 50 mg/kg) 30 min after giving Cd (oral gavage, 25 mg/kg) for 7 consecutive days. The effects of Cd and CHR treatments on oxidative stress, inflammatory response, ER stress, apoptosis and tissue damage in rat lung tissues were determined by biochemical and histological methods. Our results revealed that CHR therapy for Cd-administered rats could significantly reduce MDA levels in lung tissue while significantly increasing the activity of antioxidant enzymes (SOD, CAT, GPx) and GSH levels. CHR agent exerted antiinflammatory effect by lowering elevated levels of NF-κB, IL-1β IL-6, TNF-α, RAGE and NRLP3 in Cd-induced lung tissue. Moreover CHR down-regulated Cd-induced ER stress markers (PERK, IRE1, ATF6, CHOP, and GRP78) and apoptosis markers (Caspase-3, Bax) lung tissue. CHR up-regulated the Bcl-2 gene, an anti-apoptotic marker. Besides, CHR attenuated the side effects caused by Cd by modulating histopathological changes such as hemorrhage, inflammatory cell infiltration, thickening of the alveolar wall and collagen increase. Immunohistochemically, NF-κB and Caspase-3 expressions were intense in the Cd group, while these expressions were decreased in the Cd + CHR groups. These results suggest that CHR exhibits protective effects against Cd-induced lung toxicity in rats by ameliorating oxidative stress, inflammation, apoptosis, endoplasmic reticulum stress and histological changes.

Abstract
Endophytic fungi were isolated from the marine green alga Chaetomorpha antennina and identified as Clonostachys rosea through molecular analysis. C. rosea was grown in a tryptophan medium for 21 days and after that, the metabolites were extracted by ethyl acetate. The ethyl acetate extract showed a high cytotoxic effect on MCF-7 cells. GC-MS analysis of the ethyl acetate extract revealed the presence of many compounds, and chrysin was one of the major compounds among them. Hence, further studies were concentrated on chrysin, as it was assumed to be the major attributor to the potent cytotoxicity, based on its high anticancer efficacies reported earlier. The fungal ethyl acetate extract had been analysed for chrysin using HPTLC and compared its Rf value with authentic chrysin and it was matched. Further, the purified fungal chrysin was structurally elucidated using techniques like LC-MS and NMR analyses. Quantification revealed that C. rosea produced 1050 mg/L of chrysin. This surplus production of chrysin was the major significance of the study. The purified fungal chrysin was found to be highly cytotoxic to MCF-7 cells with a low IC50 value 35.5 ± 0.6 µM. Furthermore, DNA fragmentation and apoptosis analysis indicated the selective inhibition of MCF-7 by DNA damage. Thus, the present study implies that C. rosea is an alternative source and new method for surplus production of chrysin in the tryptophan medium. All results indicate that the marine algae endophytic C. rosa produces chrysin, and for the first time, an excess amount of production was revealed by the study.

Abstract
Ten chrysin-based pyrimidine-piperazine hybrids have been evaluated in vitro for antimicrobial activity against eleven bacterial and two fungal strains. All compounds 5a-j exhibited moderate to good inhibition, with MIC values ranging from 6.25 to 250 µg/ml. At 6.25 µg/ml and 12.5 µg/ml MIC values, respectively, compounds 5b and 5h demonstrated the most promising potency against E. coli, outperforming ampicillin, chloramphenicol, and ciprofloxacin. None of the substances had the same level of action as norfloxacin. 5a, 5d, 5g, 5h, and 5i have exhibited superior antifungal efficacy than Griseofulvin against C. albicans with 250 µg/ml MIC. All the compounds were also individually docked into the E. coli DNA gyrase ATP binding site (PDB ID: 1KZN) and CYP51 inhibitor (PDB ID: 5V5Z). The most active compound, 5h and 5g displayed a Glide docking score of - 5.97 kcal/mol and - 10.99 kcal/mol against DNA gyrase and 14α-demethylase enzyme CYP51 respectively. Potent compounds 5b, 5h, and 5g may be used to design new, innovative antimicrobial agents, according to in vitro, ADMET, and in silico biological efficacy analyses.

Abstract
Cadmium (Cd) is a toxic heavy metal that targets the kidney directly in the body. Chrysin (CHR) is a natural flavonoid with many properties such as antioxidant, anti-inflammatory and anti-apoptotic. The current study discloses new evidence as regards of the curative effects of CHR on Cd-induced nephrotoxicity by regulating oxidative stress, apoptosis, autophagy, and inflammation. Cd was administered orally at a dose of 25 mg/kg body weight alone or in combination with orally administered CHR (25 and 50 mg/kg body weight) for 7 days. Biochemical, molecular, and histological methods were used to investigate inflammation, apoptosis, autophagy, and oxidant pathways in renal tissue. Renal function tests were also evaluated. Cd caused an increase in serum toxicity markers, lipid peroxidation and a decrease in the activities of antioxidant enzymes. Nrf-2 triggered inflammatory responses by suppressing HO-1 and NQO1 mRNA transcripts and increasing NF-κB, TNF-α, IL-1β and iNOS mRNA transcripts. Cd caused inflammasome by increasing RAGE and NLRP3 mRNA transcripts. In addition, Cd application caused apoptosis by increasing Bax, Apaf-1 and Caspase-3 mRNA transcripts and decreasing Bcl-2 mRNA transcript level. It caused autophagy by increasing the activity of Beclin-1 level. CHR treatment had the opposite effect on all these values and reduced the damage caused by all these signal pathways. Overall, the data of this study indicate that renal damage associated with Cd toxicity could be ameliorated by CHR administration.

Abstract
OBJECTIVE Anesthesia-induced cognitive impairments are common for elder patients after surgery. Oxidative stress is the predominant factor contributing to the impairments. This study was to assess the therapeutic potential of an anti-oxidative naturally occurring flavonoid, chrysin, in attenuating sevoflurane-induced cognitive impairments in rat models. METHODS Rat models of cognitive impairments were constructed by exposing aged rats (18 months old) to sevoflurane for 2 h. Chrysin was administered via oral gavage at the dose of 25, 50, and 100 mg/kg/day for seven days. The elevated plus maze test was used to assess anxiety and explorative behaviors. Spatial memory tests were performed using novel object recognition test, object location memory task, and water maze experiments. Oxidative stress was evaluated by measuring levels of malondialdehyde, nicotinamide adenine dinucleotide phosphate, 4-hydroxynonenal, and glutathione using colorimetric assays. Quantitative real-time polymerase chain reaction and Western blot were used to analyze how chrysin affects nuclear factor E2-related factor (Nrf) signaling. RESULTS While sevoflurane anesthesia led to significant decline in cognitive performance in object recognition test, object location memory task, and water maze test, chrysin exerted significant effects in alleviating the impairments. Oxidative stress was also reduced in the hippocampus tissue of rats after chrysin intake. Nrf signaling was activated by chrysin treatment in sevoflurane-induced cognitive impairment models. CONCLUSION Chrysin was effective in alleviating cognitive impairments induced by sevoflurane anesthesia, which was at least in part facilitated by its effects in reducing oxidative stress via activating Nrf signaling.

Abstract
Diabetic peripheral neuropathy (DPN) is a common diabetic complication. Chrysin (CHY) has many biological properties but poor oral bioavailability. This study investigates the effect of CHY and CHY-loaded nanovesicles (CHY-NVs) on streptozotocin (STZ)-induced DPN in rats. CHY-NVs were prepared by using film hydration method. The formula with the best entrapment efficiency%, lowest particle size, highest zeta potential, and highest in vitro CHY released profile was selected, characterized by Differential scanning calorimetry, Fourier transformation infrared spectroscopy analysis, and examined by Transmission electron microscope. Acute toxicity test, pharmacokinetic study and experimental model of diabetes mellitus were performed on the selected formulation. Wistar rats were considered diabetic by administration of a single intraperitoneal dose of STZ (50 mg/kg). 48 h after STZ administration, hyperglycemic rats were randomly assigned into four groups, one group of untreated hyperglycemic rats and the other three groups received daily oral doses of unloaded NVs, CHY-NVs (25 mg/kg), and CHY-NVs (50 mg/kg), respectively for 21 days. Moreover, five additional groups of healthy rats received: distilled water (control), free CHY, unloaded NVs, and CHY-NVs respectively for 21 days. CHY and CHY-NVs maintained body weight and reduced STZ-induced behavioral changes in rotarod, hind paw cold allodynia, tail cold allodynia, tail flick, and hot plate tests. CHY and CHY-NVs lowered blood glucose, glycated hemoglobin, elevated serum reduced glutathione (GSH), and reduced plasma malondialdehyde (MDA) levels. CHY-NVs elevated phosphatidylinositol 3-kinase (Pi3k), phosphorylated protein kinase B (p-AKT), and reduced nuclear factor kappa B (NF-κB), interleukin-6 (IL-6) in sciatic nerve homogenate. CHY and CHY-NVs increased nerve growth factor (NGF) and decreased glycogen synthase kinase-3β (GSK-3β) gene expressions in the sciatic nerve. In conclusion, CHY and CHY-NVs ameliorated STZ-induced DPN behavioral and histopathological changes via attenuating hyperglycemia, exerting anti-oxidant, anti-inflammatory effects, activating NGF/p-AKT/GSK-3β pathway, and its anti-apoptotic effect. The best pharmacokinetic profile and therapeutic effect was observed in rats treated with CHY-loaded NVs.

Abstract
This study was intended to appraise the anti-inflammatory and anti-arthritic potential of Chrysin (CR), a natural dietary flavone found in several plant genera, including Passiflora and Propalis, and honey. The in vitro anti-arthritic potential was assessed by protein denaturation and membrane stabilization assays. The acute anti-inflammatory action was assessed by Carrageenan and Xylene induced oedema models in Wistar rats. For determining anti-arthritic potential, 0.1 ml Complete Freund's adjuvant was injected into the left hind paw of rats to induce adjuvant-induced arthritis, followed by initiation of treatment with individual CR at 25, 50, 100 mg/kg and in combination with methotrexate (MTX) by oral gavage for 21 days. The standard treatment group was given MTX (1 mg/kg). Treatment with MTX, chrysin and their combination exhibited a notable inhibition of paw oedema and pain, restoration of body weight and immune organ weight as evident by the histology of ankle joints. Treatment with chrysin alone and in combination significantly (p < 0.0001) restored altered blood parameters (CRP, RF, Hb, WBC, and platelets) with notable (p < 0.0001) down-regulation of interleukin (IL)-6,-1β, tumor necrosis factor-α, NF-κβ, and cyclooxygenase-2 and up-regulation (p < 0.0001) of IL-4, 10, and I-κβ in contrast to disease control rats. The treatment with the combination noticeably improved the superoxide dismutase, and catalase activities while reduced the peroxidation level in liver homogenate. It can be concluded from the findings that chrysin especially in combination with MTX ameliorated CFA-induced arthritis owing to its profound anti-oxidant, analgesic and anti-inflammatory actions.

Abstract
Mild inhibition of mitochondrial function leads to longevity. Genetic disruption of mitochondrial respiratory components either by mutation or RNAi greatly extends the lifespan in yeast, worms, and drosophila. This has given rise to the idea that pharmacologically inhibiting mitochondrial function would be a workable strategy for postponing aging. Toward this end, we used a transgenic worm strain that expresses the firefly luciferase enzyme widely to evaluate compounds by tracking real-time ATP levels. We identified chrysin and apigenin, which reduced ATP production and increased the lifespan of worms. Mechanistically, we discovered that chrysin and apigenin transiently inhibit mitochondrial respiration and induce an early ROS, and the lifespan-extending effect is dependent on transient ROS formation. We also show that AAK-2/AMPK, DAF-16/FOXO, and SKN-1/NRF-2 are required for chrysin or apigenin-mediated lifespan extension. Temporary increases in ROS levels trigger an adaptive response in a mitohormetic way, thereby increasing oxidative stress capacity and cellular metabolic adaptation, finally leading to longevity. Thus, chrysin and apigenin represent a class of compounds isolated from natural products that delay senescence and improve age-related diseases by inhibiting mitochondrial function and shed new light on the function of additional plant-derived polyphenols in enhancing health and delaying aging. Collectively, this work provides an avenue for pharmacological inhibition of mitochondrial function and the mechanism underlining their lifespan-extending properties.

Abstract
The aim of this study was to investigate the effects of baicalin, chrysin and their combinations against emamectin benzoate-induced toxicity in rats. For this purpose, sixty four rats were divided into evenly 8 groups with 6-8-week-old male Wistar albino rats, weighing 180-250 g, in each group. While the first group was kept as a control (corn oil), the remaining 7 groups were administered with emamectin benzoate (10 mg/kg bw), baicalin (50 mg/kg bw) and chrysin (50 mg/kg bw) alone or together for 28 days. Oxidative stress parameters, serum biochemical parameters and blood/tissue (liver, kidney, brain, testis and heart) and tissue histopathology were investigated. Compared to the control group, the emamectin benzoate-intoxicated rats had significantly higher tissue/plasma concentrations of nitric oxide (NO) and malondialdehyde (MDA), as well as lower tissue glutathione (GSH) concentrations and antioxidant enzyme activity (glutathione peroxidase/GSH-Px, glutathione reductase/GR, glutathione-S-transferase/GST, superoxide dismutase/SOD, catalase/CAT). Biochemical analysis showed that emamectin benzoate administration significantly increased serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activities, as well as triglyceride, cholesterol, creatinine, uric acid and urea levels, and decreased serum total protein and albumin levels. The histopathological examination of the liver, kidney, brain, heart and testis tissues of the emamectin benzoate-intoxicated rats demonstrated necrotic changes. Baicalin and/or chrysin reversed the biochemical and histopathological alterations induced by emamectin benzoate on these tested organs. Therefore, baicalin and chrysin (alone or in combination) could offer protection against emamectin benzoate-induced toxicity.

Abstract
PURPOSE Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer, accounting for 20% of cases. Due to the lack of a molecular target, limited options are available for TNBC treatment. Radiation therapy (RT) is a treatment modality for the management of TNBC following surgery; however, it has a detrimental effect on surrounding healthy tissues/cells at a higher rate. METHODS We examined the effect of RT in combination with chrysin as a possible radiosensitizing agent in an MDA-MB-231 cell line as a model of a TNBC. The growth inhibitory effects of chrysin were examined using an MTT assay. Flow cytometry was performed to evaluate apoptosis and expression of hypoxia-induced factor-1α (HIF-1α). The protein expression of p-STAT3/STAT3 and Cyclin D1 was examined using western blotting. Real-time PCR determined apoptotic-related genes (Bax, BCL2, p53). RESULTS Treatment of MDA-MB-231 cells with chrysin in combination with RT caused synergistic antitumor effects, with an optimum combination index (CI) of 0.495. Our results indicated that chrysin synergistically potentiated RT-induced apoptosis in MDA-MB-231 compared with monotherapies (chrysin and/or RT alone). Expression of HIF-1α was decreased in the cells exposed to combinational therapy. The apoptotic effect of combinational therapy was correlated with increased Bax (pro-apoptotic gene) and p53 levels along with reduced expression of Bcl-2 (anti-apoptotic gene). Increased apoptosis was associated with reduced expression of Cyclin D1, p-STAT3. CONCLUSION These findings highlight the potential effect of chrysin as a radiosensitizer, indicating the synergistic anti-cancer effect of chrysin and RT in TNBC. Further investigation is warranted in this regard.

Abstract
Chrysin is a natural flavonoid compound that has antioxidant and neuroprotective effects. Cerebral ischemia reperfusion (CIR) is closely connected with increased oxidative stress in the hippocampal CA1 region and homeostasis disorder of transition elements such as iron (Fe), copper (Cu) and zinc (Zn). This exploration was conducted to elucidate the antioxidant and neuroprotective effects of chrysin based on transient middle cerebral artery occlusion (tMCAO) in rats. Experimentally, sham group, model group, chrysin (50.0 mg/kg) group, Ginaton (21.6 mg/kg) group, Dimethyloxallyl Glycine (DMOG, 20.0 mg/kg) + chrysin group and DMOG group were devised. The rats in each group were performed to behavioral evaluation, histological staining, biochemical kit detection, and molecular biological detection. The results indicated that chrysin restrained oxidative stress and the rise of transition element levels, and regulated transition element transporter levels in tMCAO rats. DMOG activated hypoxia-inducible factor-1 subunit alpha (HIF-1α), reversed the antioxidant and neuroprotective effects of chrysin, and increased transition element levels. In a word, our findings emphasize that chrysin plays a critical role in protecting CIR injury via inhibiting HIF-1α against enhancive oxidative stress and raised transition metal levels.

Abstract
BACKGROUND Flavonoids may help ameliorate the incidence of the major causes of tumor-related mortality, such as pancreatic ductal adenocarcinoma (PDAC) and lung cancer, which are predicted to steadily increase between 2020 to 2030. Here we compared the effect of chrysin and chrysin nanoparticles (CCNPs) with 5-fluorouracil (5-FLU) on the activity and expression of mitochondrial complex II (CII) to induce apoptosis in pancreatic (PANC-1) and lung (A549) cancer cells. METHODS Chrysin nanoparticles (CCNPs) were synthesized and characterized, and the IC50 was evaluated in normal, PANC-1, and A549 cell lines using the MTT assay. The effect of chrysin and CCNPs on CΙΙ activity, superoxide dismutase activity, and mitochondria swelling were evaluated. Apoptosis was assessed using flow cytometry, and expression of the C and D subunits of SDH, sirtuin-3 (SIRT-3), and hypoxia-inducible factor (HIF-1α) was evaluated using RT-qPCR. RESULTS The IC50 of CII subunit C and D binding to chrysin was determined and used to evaluate the effectiveness of treatment on the activity of SDH with ubiquinone oxidoreductase. Enzyme activity was significantly decreased (chrysin < CCNPs < 5-FLU and CCNPs < chrysin < 5-FLU, respectively), which was confirmed by the significant decrease of expression of SDH C and D, SIRT-3, and HIF-1α mRNA (CCNPs < chrysin < 5-FLU). There was also a significant increase in the apoptotic effects (CCNPs > chrysin > 5-FLU) in both PANC-1 and A549 cells and a significant increase in mitochondria swelling (CCNPs < chrysin < 5-FLU and CCNPs > chrysin > 5-FLU, respectively) than that in non-cancerous cells. CONCLUSION Treatment with CCNPs improved the effect of chrysin on succinate-ubiquinone oxidoreductase activity and expression and therefore has the potential as a more efficient formulation than chemotherapy to prevent metastasis and angiogenesis by targeting HIF-1α in PDAC and lung cancer.

Abstract
BACKGROUND Interferon and nucleos(t)ide analogues are current therapeutic treatments for chronic Hepatitis B virus (HBV) infection with the limitations of a functional cure. Chrysin (5, 7-dihydroxyflavone) is a natural flavonoid, known for its antiviral and hepatoprotective activities. However, its anti-HBV activity is unexplored. METHODS In the present study, the anti-hepatitis B activity of chrysin was investigated using the in vitro experimental cell culture model, HepG2 cells. In silico studies were performed where chrysin and lamivudine (used here as a positive control) were docked with high mobility group box 1 protein (HMGB1). For the in vitro studies, wild type HBV genome construct (pHBV 1.3X) was transiently transfected in HepG2. In culture supernatant samples, HBV surface antigen (HBsAg) and Hepatitis B e antigen (HBeAg) were measured by enzyme-linked immunosorbent assay (ELISA). Secreted HBV DNA and intracellular covalently closed circular DNA (cccDNA) were measured by SYBR green real-time PCR. The 3D crystal structure of HMGB1 (1AAB) protein was developed and docked with the chrysin and lamivudine. In silico drug-likeness, Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) properties of finest ligands were performed by using SwissADME and admetSAR web servers. RESULTS Data showed that chrysin significantly decreases HBeAg, HBsAg secretion, supernatant HBV DNA and cccDNA, in a dose dependent manner. The docking studies demonstrated HMGB1 as an important target for chrysin as compared to lamivudine. Chrysin revealed high binding affinity and formed a firm kissing complex with HMGB1 (∆G = - 5.7 kcal/mol), as compared to lamivudine (∆G = - 4.3 kcal/mol), which might be responsible for its antiviral activity. CONCLUSIONS The outcome of our study establishes chrysin as a new antiviral against HBV infection. However, using chrysin to treat chronic HBV disease needs further endorsement and optimization by in vivo studies in animal models.

Abstract
Oxidative and endoplasmic reticulum (ER) stress-mediated cardiac apoptosis is an essential pathological process in cardiovascular diseases (CVDs). Chrysin (Chy) is a natural flavonoid that exerts several health benefits, particularly anti-oxidative and anti-apoptotic effects. However, its protective effect against CVDs and its mechanism of action at a molecular level remains unclear. Therefore, the present study aimed to investigate the interaction of ER stress response protein with Chy by computational analysis and molecular action in H2O2-induced oxidative and ER stress in cardiomyoblast cells. H9c2 cells were pre-treated with 50 μM of Chy for 24 h and exposed to H2O2 for 1 h. Explore the Chy-mediated Nrf2 signalling on ER stress reduction, H9c2 cell lines were transfected with Nrf2 siRNA for 48 h and further treated with Chy for 24 h and subjected to H2O2 for 1 h. Chy pre-treatment increased the Nrf2-regulated gene expression, reduced the ER stress signalling genes such as CHOP and GRP78, and increased the PERK and AFT6 expression compared to H2O2-treated cells. Chy preincubation down-regulated the expression of PI3K, NF-κB, and caspase-3. Fluorescence staining revealed that Chy reduced intracellular ROS generation, ER stress, apoptosis, and increased MMP. This beneficial effect of Chy was abolished when silencing Nrf2 in H9c2 cells. Overall, the present study confirmed that Chy showed the cardioprotective effect by attenuating ER stress via the activation of Nrf2 signalling. Therefore, the study concluded that improving Nrf2 signalling by Chy supplementation could provide a promising therapeutic target in oxidative and ER stress-mediated CVDs complications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As one of the important traditional Chinese medicines, Alpinia oxyphylla could warm and tonify the kidney and spleen. It has been used as anti-salivation, anti-diarrhea in various diseases. In recent years, many studies have reported the significant effect of Alpinia oxyphylla on improving cognitive ability, anti oxidative stress and protecting neurons. AIMS OF THE STUDY In this paper, we studied whether AE and its main active components could improve M1 and M2 polarization, inhibit neuroinflammation through triggering receptor expressed on myeloid cells 2 (TREM2), and exert anti-inflammatory effects. MATERIALS AND METHODS In this paper, the concentrations of inflammatory cytokines such as NO, TNF-α, IL-10 were assessed using detection kits respectively. Arg-1 and Iba-1, as polarized markers of M1 and M2, were detected by Immunofluorescence staining. CD86 and CD206 were tested by flow cytometry as surface markers of M1 and M2. Furthermore, RT-PCR was performed to determinate TNF-α, IL-10, Arg-1, and Iba-1. Western blot was used to test the activation of PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways. TREM2 siRNA treatment further verified the action target of Chrysin, the main active ingredient of Alpinia oxyphylla. Molecular docking study was performed to investigate the binding mode between Chrysin and the human TREM2. RESULTS We found that AE could promote the phenotypic transformation of microglia from M1 to M2, and similar effects of Chrysin were observed. Furthermore, downregulation of TREM2 blocked the anti-neuroinflammation of Chrysin, and inhibited the shift of M1 phenotype to M2 phenotype. Additionally, TREM2-siRNA suppressed the effects of Chrysin on PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways. CONCLUSIONS Our findings indicated that AE could improve the polarization response of microglia. TREM2 plays a vital role in the microglial repolarization effects of Chrysin through PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways regulated by neuroinflammation.

Abstract
Flavonoid metal complexes have interesting properties and are widely explored for bone regeneration owing to their potent biological activity. In the present study, we investigated the biocompatibility and osteogenic properties of the Copper(II)-chrysin complex (C/Cu). The biocompatibility of C/Cu was assessed in vitro with human osteoblastic cells and in vivo using chick embryo and zebrafish models. The C/Cu complex was found to be cytofriendly with good biocompatibility. The osteogenic property of C/Cu was studied at cellular and molecular levels. C/Cu promoted mineralization in osteoblastic cultures by increasing ALP activity. At the molecular level, C/Cu significantly promoted the mRNA levels of osteoblast differentiation marker genes such as runt-related transcription factor 2 (Runx2), Type 1 collagen and ALP. In addition to this, secretory proteins, osteonectin (ON) and osteocalcin (OC) levels were also stimulated. We have also identified that C/Cu exhibited enhanced osteogenic properties and antibacterial activity compared with Chrysin. Thus, C/Cu can be used as an osteogenic agent in bone tissue engineering.

Abstract
The aim of this survey was to load Chrysin (CHY) on solid lipid nanoparticles (SLNs) and decorate the nanoparticles with folate-bound chitosan to increase the effectiveness of the treatment. CHY-SCF-NPs were synthesized by homogenizing and sonication methods and characterized. FA binding and encapsulation efficiency (HPLC), antioxidant capacity (ABTS and DPPH), cell viability assay (MTT), programmed cell death analysis (fluorescence staining, flow cytometry, and qPCR), and angiogenesis (CAM and molecular analysis) assay were done for assessment of therapeutic efficiency of CHY-SCF-NPs. Increases in size and change in surface charge of CHY-SLNs (PS: 84.3 nm and ZP: -18 mV) were reported after coating with folate-bound chitosan (PS: 125 nm and ZP: +34.9 mV). CHY-SCF-NPs inhibited PANC, MCF-7, A2780, and HepG2 as malignant cells and HFF as normal cells with IC50∼53, 55, 249, and >250 µg/mL, respectively. Also, CHY-SCF-NPs scavenged ABTS (IC50: 123.73 µg/mL), and DPPH (IC50: 108.7 µg/mL) free radicals and suppressed angiogenesis in the CAM and qPCR assays. Up-regulation of Bax and caspase 9 genes as well as the fluorescence staining and cell cycle results confirmed the pro-apoptotic properties of CHY-SCF-NPs. CHY-SCF-NPs can be considered a promising anti-cancer candidate for preclinical and clinical studies of pancreatic cancer.

Abstract
Chrysin (Chr) has drawn a lot of attention recently due to its possible anticancer properties. However, Chr's short half-life and low bioavailability restricted its utility as a medicinal agent. The purpose of this research is to design, synthesize, and test the cytotoxic effects of nano-niosomes containing chrysin (Chr-Nio) on the SKOV3 ovarian cancer cell line. Chr-Nio has a nanoparticle polydispersity index (PDI) of 0.156 and a zeta potential of - 27.4 mV, with an average diameter of 105 nm. Furthermore, Chr was encapsulated in Nio with an entrapment effectiveness of 85.5%. Chr-Nio cytotoxicity was shown to be more than free Chr in a time- and dose-dependent manner. Furthermore, as compared to free Chr-treated cells, the mRNA expression level of apoptotic genes Bcl-2, Bax, and caspase-3 in Chr-Nio-treated cells was considerably altered. According to the data, Chr may inhibit SKOV3 cell migration in vitro scratch wound experiments in a dose-dependent manner, and cells treated with Chr-Nio had the highest percentage of cell death. The findings of this study suggested that encapsulating Chr in niosome nanoparticles might be an effective medication delivery strategy for increasing Chr anticancer effects in the treatment of ovarian cancer.

Abstract
Cancer is a disease of global importance. In order to mitigate conventional chemotherapy-related side effects, phytochemicals with inherent anticancer efficacy have been opted. However, the use of nanotechnology is essential to enhance the bioavailability and therapeutic efficacy of these phytochemicals. Herein, we have formulated folic acid conjugated polyacrylic acid capped mesoporous silica nanoparticles (∼47.6 nm in diameter) for pH-dependent targeted delivery of chrysin to breast cancer (MCF-7) cells. Chrysin loaded mesoporous silica nanoparticles (Chr- mSiO2@PAA/FA) have been noted to induce apoptosis in MCF-7 cells through oxidative insult and mitochondrial dysfunction with subsequent G1 arrest. Further, in tumor bearing mice, intravenous incorporation of Chr-mSiO2@PAA/FA has been noticed to enhance the anti-neoplastic effects of chrysin via tumor site-specific accumulation. Enhanced cytotoxicity of chrysin contributed towards in vivo tumor regression, restoration of normalized tissue architecture and maintenance of healthy body weight. Besides, no serious systemic toxicity was manifested in response to Chr-mSiO2@PAA/FA administration in vivo. Thus, the study evokes about the anticancer potentiality of chrysin and its increased therapeutic activity via incorporation into folic acid conjugated mesoporous silica nanoparticles, which may hold greater impact in field of future biomedical research.

Abstract
AIM The study aims to investigate the combined effects of chrysin and cisplatin on hepatoma(HepG2) cell lines in vivo and in vitro. OBJECTIVE Studies have suggested that chrysin can enhance the sensitivity of tumor cells to apoptosis. Drug resistance in tumor cells reduced the effectiveness of chemotherapy drugs such as cisplatin. We investigated whether the combination of chrysin and cisplatin can induce more apoptosis than chrysin alone and cisplatin alone. METHODS HepG2 cells were pretreated with chrysin for 2 h, followed by the addition of cisplatin for another 24 h. The morphologic changes were observed under inverted microscope and the cell viability was measured using the MTT test. The protein and cleavage of caspase-3,8,9, PARP, and cFLIP were determined by Western blotting. RESULTS The cell viability of the HepG2 cell can be reduced by the combination of chrysin pretreatment for 2 h and cisplatin addition for 24 h; Caspase-3,8,9 and PARP were cleaved after 12 h treatment with chrysin and cisplatin; Pancaspase inhibitor, Z-VAD-fmk, could reverse the apoptosis induced by chrysin and cisplatin in HepG2 cells; cFLIP was down-regulated by the combination of chrysin and cisplatin, and could be reversed by Z-VAD-fmk; the xenografted HepG2 cells formed a tumor in one week; At the end of the experiment, there were significant differences in relative tumor volume (RTV) and relative tumor proliferation rate between the combined group and the control group, the chrysin group and the cisplatin group; Western blotting showed that the levels of PARP, cFLIP, and caspase-3 proteins in isolated tumor tissues also decreased under the combined action of chrysin and cisplatin. CONCLUSION The combination of chrysin and cisplatin induces apoptosis of hepatic tumor in vivo and in vitro. It downregulates cFLIP and then activates caspase-8, which triggers caspase-mediated apoptosis of HepG2 cell.

Abstract
Chrysin, a bioflavonoid belonging to the flavone, occurs naturally in plants such as the passionflower, honey and propolis. Few studies have demonstrated that chrysin can promote vasorelaxant activities in rats' aorta and mesenteric arteries. To date, no research has explored the signalling system routes that chrysin may utilise to produce its vasorelaxant action. Therefore, this study aimed to investigate the underlying mechanisms involved in chrysin-induced vasorelaxant in rats' aortic rings and assess the antihypertensive effect of chrysin in spontaneously hypertensive rats (SHRs). The findings revealed that chrysin utilised both endothelium-dependent and endothelium-independent mechanisms. The presence of L-NAME (endothelial NO synthase inhibitor), ODQ (sGC inhibitor), methylene blue (cGMP lowering agent), 4-AP (voltage-gated potassium channel inhibitor), atropine (muscarinic receptors inhibitor) and propranolol (β-adrenergic receptors inhibitor) significantly reduced the chrysin's vasorelaxant action. Furthermore, chrysin can reduce intracellular Ca2+ levels by limiting the extracellular intake of Ca2+ through voltage-operated calcium channels and blocking the intracellular release of Ca2+ from the sarcoplasmic reticulum via the IP3 receptor. These indicate that chrysin-induced vasorelaxants involved NO/sGC/cGMP signalling cascade, muscarinic and β-adrenergic receptors, also the potassium and calcium channels. Although chrysin had vasorelaxant effects in in vitro studies, the in vivo antihypertensive experiment discovered chrysin does not significantly reduce the blood pressure of SHRs following 21 days of oral treatment. This study proved that chrysin utilised multiple signalling pathways to produce its vasorelaxant effect in the thoracic aorta of rats; however, it had no antihypertensive effect on SHRs.

Abstract
Lead (Pb) is a highly poisonous environmental pollutant that can induce cognitive decline. Chrysin, a natural flavonoid compound, has anti-oxidative, anti-inflammatory, and neuroprotective properties in different neurodegenerative disorders. The present study was designed to examine the putative effects of chrysin against Pb-induced cognitive impairment and the possible involved mechanisms. Adult male Wistar rats were exposed to Pb acetate (500 ppm in standard drinking water) either alone or in combination with daily oral administration of chrysin (30 mg/kg) for eight consecutive weeks. During the eight-week period of the study, the cognitive capacity of the rats was evaluated by employing both novel object recognition and passive avoidance tests. On day 56, hippocampal synaptic plasticity (long-term potentiation; LTP) was recorded in perforant path-dentate gyrus (PP-DG) synapses to assess field excitatory postsynaptic potentials (fEPSPs) slope and population spike (PS) amplitude. Subsequently, pro- and anti-inflammatory cytokines and histological changes were evaluated in the cerebral cortex and hippocampus of the rats. Moreover, Pb levels in blood and brain tissues were assessed. The results showed that Pb exposure causes cognitive decline, inhibition of hippocampal LTP induction, imbalance of pro- and anti-inflammatory cytokines, enhancement of Pb levels in blood and brain tissues, and neuronal loss. However, chrysin treatment improved cognitive dysfunction, ameliorated hippocampal LTP impairment, modulated inflammatory status, reduced Pb concentration, and prevented neuronal loss in the Pb-exposed rats. The results suggest that chrysin alleviates Pb-induced cognitive deficit, possibly through mitigation of hippocampal synaptic dysfunction, modulation of inflammatory status, reduction of Pb concentration, and prevention of neuronal loss.

Abstract
The present study aimed to improve the neuroprotective effect of chrysin (CHR) by combining two formulation techniques, phospholipid (PL) complexation and solid dispersion (SD). CHR-phospholipid complex (CHR-PLC) was prepared through solvent evaporation. The molar ratio CHR/PL (1:3), which exhibited the highest complexation efficiency, was selected for the preparation of CHR-PLC loaded SD (CHR-PLC-SD) with 2-hydroxypropyl β cyclodextrin (2-HPβCD) and polyvinylpyrrolidone 8000. CHR-PLC/2-HPβCD (1:2, w/w) displayed the highest aqueous solubility of CHR (5.86 times more than that of plain CHR). CHR-SD was also prepared using 2-HPβCD for comparison. The in vitro dissolution of CHR-PLC-SD4 revealed an enhancement in the dissolution rate over CHR-PLC (1:3), CHR-SD, and plain CHR by six times. The optimum formulations and plain CHR were evaluated for their neuroprotective effect on brain aging induced by D-galactose in mice. The results demonstrated a behavioral activity elevation, an increase of AMPK, LKB1, and PGC1α brain contents as well as a reduction of AGEs, GFAP, NT-3, TNF-α, and NF-κβ brain contents when compared with those of the D-galactose control group. Thus, the developed formulations stimulated neurogenesis and mitochondrial biogenesis as well as suppressed neuroinflammation and neurodegeneration. The order of activity was as follows: CHR-PLC-SD4 > CHR-PLC (1:3) > CHR-SD > plain CHR.

Abstract
BACKGROUND Diclofenac (DF) is a non-steroidal anti-inflammatory drug (NSAID) generally prescribed for the treatment of pain. In spite of the widespread use of DF, hepatotoxicity has been reported after its administration. The current study discloses new evidence as regards of the curative effects of chrysin (CHR) on DF-induced hepatotoxicity by regulating oxidative stress, apoptosis, autophagy, and endoplasmic reticulum (ER) stress. METHODS The animals were separated into five different groups. Group-I was in control. Group-II received CHR-only (50 mg/kg bw, p.o.) on all 5 days. Group-III received DF-only (50 mg/kg bw, i.p.) on 4th and 5th day. Group-IV received DF (50 mg/kg bw) + CHR (25 mg/kg, bw) and group-V received DF (50 mg/kg, bw) + CHR (50 mg/kg, bw) for 5 days. RESULTS DF injection was associated with increased MDA while reduced GSH level, activities of superoxide dismutase, glutathione peroxidase, and catalase and mRNA levels of HO-1 and Nrf2 in the liver. DF injection caused apoptosis and autophagy in the liver by up-regulating caspase-3, Bax, LC3A, and LC3B levels and down-regulating Bcl-2. DF also caused ER stress by increasing mRNA transcript levels of ATF-6, IRE1, PERK, and GRP78. Additionally, it was observed that DF administration up-regulated MMP2 and MMP9. However, treatment with CHR at a dose of 25 and 50 mg/kg considerably ameliorated oxidative stress, apoptosis, autophagy, and ER stress in liver tissue. CONCLUSION Overall, the data of this study indicate that liver damage associated with DF toxicity could be ameliorated by CHR administration.

Abstract
Brain disorders are currently one of the world's most serious and difficult health issues. These brain disorders are accountable for a massive number of morbidities and mortalities around the world. The current treatments of these disorders are frequently accompanied by severe side effects and cause a detrimental effect on health. Recently, plant flavonoids have sparked a surge in public and scientific attention because of their alleged health-promoting impact and almost no adverse repercussions. Also, scientific research has shown that phytochemicals possess numerous neuroprotective properties under in vivo and in vitro conditions. Chrysin is a therapeutic phytochemical that falls under the class of flavonoids based on its structure. The biological activities and pharmacological effects of chrysin include anticancer, antioxidant, and anti-inflammatory activities as well as amyloidogenic and neurotrophic effects. These therapeutic abilities of chrysin are attributed to its structural diverseness arising in ring-A and lack of oxygenation in B and C rings. Several studies have highlighted the rising significance of chrysin in a variety of brain illnesses, like Alzheimer's disease, Parkinson's disease, depression, anxiety, brain tumours, epilepsy, multiple sclerosis, traumatic brain injury, spinal cord injury, and ischemic stroke. This study depicts the relationship of chrysin with different brain-related disorders and discusses the mechanisms responsible for the potential role of chrysin as a pharmacological agent for the treatment and management of different brain disorders based on the results of several preclinical studies and taking into account the therapeutic effects of the compound.

Abstract
OBJECTIVE The incidence of breast cancer continues to rise despite decades of laboratory, epidemiological and clinical research. Breast cancer is still the leading cause of cancer death in women. Cyclin D1 is one of the most important oncoproteins associated with cancer cell proliferation and is overexpressed in more than 50% of cases. Curcumin and chrysin are plant-derived components that are believed to assist in inhibiting the viability of breast cancer cells. These agents are involved in cancer cells' growth and reducing cyclin D1 expression. In this study, the hypothesis of combining curcumin and chrysin is applied to analyze the potential synergistic effect in inhibiting cancer cell proliferation and down-regulation of cyclin D1. Furthermore, applying PLGA-PEG NPs could improve the bioavailability of free curcumin and chrysin components and at the same time increases the anti-cancer potential of this compound. METHODS PLGA-PEG NPs were synthesized via the ring-opening polymerization technique and characterized with FT-IR and FE-SEM for chemical structure and morphological characteristics, respectively. Next, curcumin and chrysin were loaded in PLGA-PEG NPs and MTT assay was performed to assess the cytotoxic effect of these agents. T-47D cells were treated with appropriate concentrations of these agents and cyclin D1 expression level was evaluated by real-time PCR. RESULTS The obtained results from FT-IR and FE-SEM techniques illustrated that curcumin and chrysin were efficiently encapsulated into PLGA-PEG NPs. Curcumin, chrysin, and curcumin-chrysin in free and nano-encapsulated forms exhibited an anti-cancer effect on T-47D cells in a time- and dose-dependent manner, especially in a combination of free and encapsulated forms demonstrated synergistic anti-cancer effects. Compared to free form, Nano-curcumin, Nano-chrysin, and Nano-combination remarkably down-regulated cyclin D1 gene expression. (p-value < 0.05). CONCLUSION Our results revealed that the curcumin-chrysin combination has a synergistic effect and the encapsulated form of this nano-component has more inhibition on cyclin D1 expression.<br />.

Abstract
Chrysin is a natural bioactive compound that is extracted from many trees, honey, and propolis. Chrysin has several pharmacological activities such as anti-inflammatory, anti-cancer, and antioxidant properties. This study was performed to evaluate the anti-cancer activities of chrysin in cancer therapy. The present study was conducted by systematic review of studies published up to August 2021. Related studies were identified by searching Web of Science (WoS), PubMed, Science Direct, SID, MagIran, Scopus, and Google Scholar databases. The keywords of chrysin, cancer, anti-cancer, and cancer therapy were used for searching. The quality of the studies was assessed by the CONSORT checklist. A total of 21 studies were identified. The results of studies showed that chrysin has an anticancer effect by stimulating apoptosis in a wide range of human cells and rats. Chrysin is also an important factor in inhibiting tumor growth and neoplasticity. Chrysin inhibits the growth and proliferation of cancer cells by inducing cytotoxic effects. Therefore, due to the antitumor effects of chrysin and its safety and non-toxicity towards normal cells, this compound can be considered as an adjuvant along with chemotherapeutic agents in cancer treatment.

Abstract
Chrysin (Chy) is known for various biological proprieties such as inhibitory effects on inflammation, cancer, oxidative stress, aging, and atherosclerosis. However, the hypolipidemic activity of Chy and its mechanistic action remains unclear in cardiovascular diseases (CVD). In this study, we focused on the hypolipidemic proprieties of Chy in hypercholesterolemia-induced atherosclerosis. Male Wistar rats (150-220 g) were divided into four groups as follows: Group I control was fed with standard laboratory chow. Rats in Group II were fed a high-fat diet (HFD) for 60 days. After 60 days of HFD, Group III rats received Chy (100 mg/kg body weight); Group IV rats received Atorvastatin (Atv; 10 mg/kg body weight) for 30 days. Biochemical studies showed Chy, Atv treatment decreased the activities of liver marker enzymes and the levels of Reactive Oxygen Species (ROS) and lipid profile. Gene expression analysis on nuclear factor erythroid 2-related factor 2 (Nrf2) and its regulated genes were significantly reduced in the intestine and increased in the aorta by Chy and Atv. Gut microbial species such as Bacteroidetes, Lactobacillus, Enterococcus, and Clostridium leptum copy numbers were significantly increased by Chy and Atv treatment. In addition, Chy and Atv modulated the expression of inflammatory genes including TLR4, TNFα, NLRP3, and IL-17 in the aorta and intestine compared with hypercholesterolemic control rats. Chy and Atv effectively increased the caspase-3 mRNA expression in the intestine, but these decreased in the aorta. The present study concludes that by reducing oxidative stress and increasing gut microbial colonization, Chy may provide an effective therapeutic approach for the prevention of hypercholesterolemia-mediated atherosclerosis. PRACTICAL APPLICATIONS: Our study focused on a therapeutic model representing the clinical presentation of atherosclerosis in humans. Statins are commonly used in the treatment of cardiovascular complications, patients with hypercholesterolemia face difficulties in the continuation of statin therapy. The reason for statin discontinuation has been associated with toxicological effects. It is necessary to investigate the potentiality of the natural compound as an alternative medicine to statin with fewer side effects. The main theme of our study is to compare the therapeutic potential of Chy and Atv. Chy is a natural bioflavonoid that could be considered as an alternative medicinal compound to statins and to avoid toxicity problems associated with statins. Chy is a bioflavonoid present in Passiflora caerulea (blue passion flower), Oroxylum indicum (Indian trumpet flower), Pelargonium crispum, propolis, and honey. Consuming Chy-rich foods will reduce hypercholesterolemia-mediated cardiovascular complications. Overall, the present studies provided a key to developing bioactive compounds-based foods for CVD patients.

Abstract
The aim of this study was to investigate the potential therapeutic efficacy of chrysin (CHS) against ovotoxicity caused by intraperitoneal administration of cisplatin (CDDP) in rats. In this experimental study, 24 female rats were randomly divided into four groups: control, CHS (2 mg/kg), CDDP (5 mg/kg) and CDDP (5 mg/kg) + CHS (2 mg/kg). The levels of malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), superoxide dismutase (SOD), interleukin-6 (IL-6) and myeloperoxidase (MPO) were determined in the ovarian tissues using spectrophotometric methods. In addition, the ovarian samples were evaluated histopathologically by hematoxylin&eosin staining. The results revealed that the levels of MDA, TOS, IL-6 and MPO significantly increased by CDDP administration compared with control group (p < 0.05). Also, it was found that CDDP significantly decreased TAS and SOD levels (p < 0.05). CHS ameliorated CDDP-induced the increased levels of MDA, TOS, IL-6, MPO and increased the levels of TAS and SOD significantly (p < 0.05). Histological findings also supported the therapeutic effect of CHS against CDDP-induced ovarian damage parameters. In conclusion, our results showed that CHS exhibits a therapeutic effect against CDDP-induced ovotoxicity and therefore the use of CHS after chemotherapy may improve the side effets of CDDP. IMPACT STATEMENTWhat is already known about this subject? Cisplatin (CDDP) is an effective and widely used chemotherapeutic agent to treat various malignancies, but its therapeutic use is limited due to dose-related tissue toxicity. Chrysin (CHS), a natural flavone, exhibits various beneficial activities, including antioxidant, anti-inflammatory and anticancer. There are increasing evidences in the literature that CHS reduces the toxicity of various chemotherapeutic agents, such as CDDP, doxorubicin and cyclophosphamide, in colon, kidney and liver tissues through its antioxidant and anti-inflammatory potential.What do the results of this study add? This study demonstrated that CHS can abolish CDDP-induced in vivo ovarian injury by decreasing MDA, TOS, IL-6 and MPO levels and increasing SOD and TAS levels through its antioxidant and anti-inflammatory potential.What are the implications of these findings for clinical practice and/or further research? This study revealed the therapeutic potential of CHS against CDDP-induced acute ovotoxicity, for the first time. Further pre-clinical studies are necessary to prove the beneficial effect of CHS on the prevention of CDDP-induced ovarian toxicity.
