Pharmacol Ther 2025; 271:108864. [PMID: 40274196 DOI: 10.1016/j.pharmthera.2025.108864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2024] [Revised: 02/27/2025] [Accepted: 04/20/2025] [Indexed: 04/26/2025]
Abstract
Atherosclerosis and its associated cardiovascular complications remain significant global public health challenges, underscoring the urgent need for effective therapeutic strategies. Endothelial cells are critical for maintaining vascular health and homeostasis, and their dysfunction is a key contributor to the initiation and progression of atherosclerosis. Targeting endothelial dysfunction has, therefore, emerged as a promising approach for the prevention and management of atherosclerosis. Among natural products, flavonoids, a diverse class of plant-derived phenolic compounds, have garnered significant attention for their anti-atherosclerotic properties. A growing body of evidence demonstrates that flavonoids can mitigate endothelial dysfunction, highlighting their potential as endothelial dysfunction-targeted therapeutics for atherosclerosis. In this review, we summarize current knowledge on the roles of natural flavonoids in modulating various aspects of endothelial dysfunction and their therapeutic effects on atherosclerosis, focusing on the underlying molecular mechanisms. We also discuss the challenges and future prospects of translating natural flavonoids into clinical applications for cardiovascular medicine. This review aims to provide critical insights to advance the development of novel endothelium-protective pharmacotherapies for atherosclerosis.

Sağır S, Unsal V, Oner E, Yıldız R, Mert BD. Comparison of PDE-5 inhibitors used in erectile dysfunction with some candidate molecules: A study involving molecular docking, ADMET, DFT, biological target, and activity. BMC Urol 2025; 25:47. [PMID: 40069715 PMCID: PMC11895370 DOI: 10.1186/s12894-025-01727-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2024] [Accepted: 02/25/2025] [Indexed: 03/15/2025] Open
Abstract
Erectile dysfunction (ED) is a urological condition defined as the inability of a man to achieve or maintain an erection. This condition negatively affects his sexual performance and the performance of his partner. Phosphodiesterase type 5 (PDE5) inhibitors are commonly used to treat ED. Arginase II plays an important role in regulating L-arginine to NO synthase in the smooth muscle of the human corpus cavernosum of the penis. NO is a molecule essential for regulating a variety of functions, including arterial blood pressure, penile erection, and energy balance. Substances such as vardenafil, alprostadil, papaverine, and resveratrol increase NO production, thereby supporting sexual function and vascular health. Additionally, NO donors such as L-arginine, L-citrulline, and α-lipoic acid provide effective alternatives when used in combination with PDE5 inhibitors. Medications used in the treatment of ED include vardenafil, alprostadil, and papaverine. In addition, although molecules such as L-arginine, citrulline, resveratrol, alpha-lipoic acid, and rutin are thought to play a role in ED, their pharmacological and molecular effects have not been sufficiently elucidated. The aim of this study was to investigate the effects of these molecules in the treatment of ED by computer-based calculations, to obtain new information about them and to inspire new treatment strategies for ED. The physicochemical, molecular and pharmacokinetic properties of the compounds were determined by SwissADME software, and ADMET (absorption, distribution, metabolism, excretion and toxicity) data were determined by ADMETlab 3.0 software. Biological target and activity data were obtained by MolPredictX and PASS Online software. While the Gaussian 09 program was used for DFT calculations, PyMOL, AutodockTools 4.2.6, AutoDock Vina, and Biovia Discovery programs were used for molecular docking studies. It was found that L-arginine, citrulline, resveratrol and α-lipoic acid were well absorbed from the intestine, while rutin showed limited absorption. When their metabolic risks were evaluated, L-arginine and citrulline were found to have lower toxicity. Molecular docking results of rutin and resveratrol were remarkable. The electronic properties of the compounds were explained by DFT calculations. L-arginine and citrulline were found to have low toxicity and positive therapeutic effects. L-arginine and citrulline stand out as promising candidates for future research. Although resveratrol data are promising, unfortunately their potential toxicity and metabolic interactions require further investigation. It is important to learn more about these compounds or conduct research to improve their therapeutic efficacy. Although computer-based calculations play an important role in toxicity predictions, drug interactions, pharmacokinetics and toxicity properties should be carefully evaluated.

Abstract
Atherosclerosis, a chronic inflammatory disease characterized by the accumulation of lipids and immune cells within arterial walls, remains a leading cause of cardiovascular morbidity and mortality worldwide. Oxidative stress and inflammation are central to its pathogenesis, driving endothelial dysfunction, foam cell formation, and plaque instability. Emerging evidence highlights the potential of bioactive compounds with antioxidant and anti-inflammatory properties to mitigate these processes and promote vascular health. This review explores the mechanisms through which bioactive compounds-such as polyphenols, carotenoids, flavonoids, omega-3 fatty acids, coenzyme Q10, and other natural compounds-modulate oxidative stress and inflammation in atherosclerosis. It examines their effects on key molecular pathways, including the inhibition of reactive oxygen species (ROS) production, suppression of nuclear factor-κB (NF-κB), and modulation of inflammatory cytokines. By integrating current knowledge, this review underscores the therapeutic potential of dietary and supplemental bioactive compounds as complementary strategies for managing atherosclerosis, paving the way for future research and clinical applications.

Abstract
Limiting animal experiments is essential for ethical issues and also because scientific evidence highlights the discrepancies between human and animal metabolism. This review aims to provide a critical discussion of the strengths and limitations of the most appropriate in vitro intestine model to answer complex research questions in pharmaceutical and nutraceutical fields. This review describes the components contributing to the definition of the gut barrier structure, from the outer mucus layer to the inner part of lamina propria, including endothelial and neuronal networks. We conclude that the main advantage of these co-culture models is their versatility since they are modulable systems in which each component can be added, changed, or removed to reproduce a specific physiological condition each time. Additionally, we compare intestinal organoid models and microfluidic systems with well-established co-culture models.

Abstract
Objectives This study aims to assess the potential mechanism of rutin to treat triple-negative breast cancer (TNBC) based on network pharmacology followed by in vitro experiments. Methods The potential rutin targets were predicted, and the DisGeNET database was used to obtain the disease targets. The intersection targets were identified with Venny 2.1 software, with the String database subsequently used as input to produce the "drug-target-disease" visual network employing Cytoscape 3.7.2. Gene ontology. Kyoto Encyclopaedia of Genes and Genomes analyses were performed for intersection targets, while AutoDock Vina was used for molecular docking and visualization. Cell viability was assessed using the Colorimetric CCK-8 test, and apoptosis was analyzed using PI/Annexin V. The predicted core targets were confirmed by qPCR and western blotting assays. Results EGFR, IL6, TNF, and INS were found as the primary targets. The molecular docking analysis revealed the rutin interaction with the core targets. The in vitro results confirmed that rutin inhibited the growth of the MDA-MB-231 cell line. Rutin also induced cell death and decreased the expressions of IL6, TNF, INS, and EGFR. Conclusion Rutin's multi-target effects and molecular mechanism for treating TNBC were confirmed through preliminary results. The results provide a theoretical base for rutin's possible function in breast cancer treatment.

Abstract
BACKGROUND Rutin, often known as vitamin P, is a natural flavonoid compound, which offers a broad spectrum of therapeutic potentials. Rutin is metabolised to different compounds by the gut bacteria after consumption, therefore, very little is absorbed. Higher plants contribute to rutin synthesis in large quantities, and it may also be found in many fruits and fruity rinds, particularly citrus fruits and berries. OBJECTIVE The present paper highlights several studies and patents conducted on rutin along with its nanoformulations regarding its broad spectrum of therapeutic potentials. METHODS Numerous electronic databases, including Springer, PubMed, Science Direct, Pubchem, Google Patents etc. were searched to extract relevant published literature demonstrating rutin effectiveness in various ailments. RESULTS The reviewed literature showed that rutin and related flavonoids possess a variety of physiological properties that protects human beings, plants and animals. Antioxidant, anti-inflammatory, anti-allergic, cytoprotective, vasoprotective, anticarcinogenic, neuroprotective, cardioprotective, antibacterial, antiviral, antiprotozoal, antitumor, anti-hypertensive antiplatelet, antispasmodic and hypolipidemic, activities. Nanotechnology has been implemented for the improvement of the bioavailability of rutin using novel drug-delivery carriers. CONCLUSION The study concludes that the development of rutin nanoformulations for multiple therapeutic approaches contributes towards enhanced aqueous solubility as well as tailored pharmacokinetics compared to conventional delivery of rutin. However, more investigations should be conducted to confirm the improved bioavailability of the rutin nanoformulations.

Int J Mol Sci 2024; 25:13272.

Abstract
Previously, we confirmed systemic antihypertensive and antioxidant properties of Urtica dioica L. leaf extract (UE) in spontaneously hypertensive rats (SHR). Here, we aimed to evaluate whether UE can alter the NO and Nrf-2 signaling to prevent local oxidative stress and kidney damage in the model of essential hypertension. SHR were divided into five groups: SHRC-control, received 0.5 mL/day of water, SHR+L received 10 mg/kg/day of losartan, SHR+UE10, SHR+UE50, and SHR+UE200 received 10, 50, and 200 mg/kg/day during next 4 weeks. At the end of the experiment, urine samples were collected for albuminuria and nitrate/nitrite assessment. Mean arterial pressure (MAP) was measured, and blood samples were collected for plasma creatinine evaluation. Kidneys were analyzed for nitrate/nitrite, oxidative stress, and target molecules by biochemical, Western blot, and immunofluorescent techniques. Losartan and UE50 significantly reduced MAP, albuminuria, oxidative stress, fibroinflammatory markers, and NRF-2/CAT/SOD signaling, with a significant increase in 6-nitrotryptophan and eNOS expressions compared to control. The effects of UE showed dose dependence. Beneficial effects of UE and losartan were independent of NRF-2 signalization in SHR. Interestingly, all treatments induced the increase in 6-nitrotryptophan expression, thus further studies are needed to elucidate the mechanisms of such nitrated tryptophan.

Abstract
The term "flavonoid" encompasses a group of plant compounds, predominantly flavonoids, present in fruits, vegetables, and other plant-based foods. These compounds deliver significant health benefits, including potent antioxidant properties that protect cells from free radicals, thereby mitigating aging and disease. We assessed study quality and bias using the Cochrane Risk of Bias tool and the Newcastle-Ottawa Scale. Inclusion criteria specified that the studies must examine a natural flavonoid from fruits, must involve animal or human trials, must be original studies, and must be English articles on the flavonoid's health and cancer-prevention effects, excluding conference abstracts and single-case studies. We conducted a comprehensive search of major databases including PubMed, Web of Science, Embase, SCOPUS, and Google Scholar, reviewing six clinical trials with total sample sizes of over 50 to 1500 participants. The results indicate that consuming flavonoid-rich fruits can aid in cancer prevention by targeting angiogenic and cancer-protective pathways. We specifically selected tomatoes, mulberries, Amazon grapes, apples, and citrus fruits due to their well-documented high levels of flavonoids and the robust clinical evidence supporting their physiological effects. In particular, citrus fruits contain additional beneficial phytochemicals that complement the action of flavonoids, enhancing their overall health effects. The anti-cancer mechanisms of flavonoids are not well-defined in the scientific literature, suggesting a gap that this study aims to address. Our study provides novel contributions by demonstrating how flavonoid supplementation induces anti-cancer effects through angiogenesis, anti-inflammatory actions, antioxidant-induced apoptosis, and modulation of pathways like PI3K/Akt and MAPK. These effects were particularly notable in the prevention and progression of breast, colon, liver, and lung cancers, with statistical significance (p < 0.05). By elucidating specific mechanisms and pathways, this study contributes to the understanding of flavonoids' role in cancer prevention and underscores the potential for developing natural anti-cancer therapeutics through the inclusion of flavonoid-rich fruits in the diet. Future research should focus on randomized controlled trials assessing long-term effects of flavonoid supplementation in diverse populations, exploring optimal dosages, and understanding interactions with conventional cancer therapies to provide comprehensive evidence for clinical applications.

Abstract
Introduction: Several signaling pathways are activated during hypoxia to promote angiogenesis, leading to endothelial cell patterning, interaction, and downstream signaling. Understanding the mechanistic signaling differences between endothelial cells under normoxia and hypoxia and their response to different stimuli can guide therapies to modulate angiogenesis. We present a novel mechanistic model of interacting endothelial cells, including the main pathways involved in angiogenesis. Methods: We calibrate and fit the model parameters based on well-established modeling techniques that include structural and practical parameter identifiability, uncertainty quantification, and global sensitivity. Results: Our results indicate that the main pathways involved in patterning tip and stalk endothelial cells under hypoxia differ, and the time under hypoxia interferes with how different stimuli affect patterning. Additionally, our simulations indicate that Notch signaling might regulate vascular permeability and establish different Nitric Oxide release patterns for tip/stalk cells. Following simulations with various stimuli, our model suggests that factors such as time under hypoxia and oxygen availability must be considered for EC pattern control. Discussion: This project provides insights into the signaling and patterning of endothelial cells under various oxygen levels and stimulation by VEGFA and is our first integrative approach toward achieving EC control as a method for improving angiogenesis. Overall, our model provides a computational framework that can be built on to test angiogenesis-related therapies by modulation of different pathways, such as the Notch pathway.

Abstract
Background A proprietary combination of Garcinia mangostana fruit rind and Cinnamomum tamala leaf extracts (LI80020F4, CinDura®) improved the physical performance and muscle strength of resistance-trained adult males. Objective This study assessed the underlying mechanisms of the ergogenic potential of LI80020F4 in in vitro and in vivo models. Methods The individual extracts and their combination (LI80020F4) were assessed for nitrite production in EAhy926 human endothelial cells. Subsequent experiments evaluated the effect of LI80020F4 in myotube formation in C2C12 mouse myoblasts, expression of mammalian target of rapamycin (mTOR) signaling proteins, myogenic factors, and mitochondrial functions in L6 rat myoblasts.Moreover, adult male ICR mice were randomly assigned (n = 15) into vehicle control (G1), exercise alone (G2), oxymetholone-16 mg/kg body weight (bw) (G3), and 75 (G4)-, 150 (G5)-, or 300 (G6) mg/kg bw of LI80020F4, orally gavaged for 28 days. G1 and G2 mice received 0.5% carboxymethylcellulose sodium. Following completion, muscle strength and physical performance were assessed on forelimb grip strength and forced swimming test (FST), respectively. Gastrocnemius (GA), tibialis anterior (TA) muscle weights, muscle fiber cross-sectional area (CSA), levels of muscle, and serum protein markers were also determined. Results LI80020F4 increased nitrite production in EAhy926 cells in a dose-dependent manner. LI80020F4 induced C2C12 myotube formation, increased mitochondrial biogenesis, upregulated the expressions of activated mTOR and other mitochondria and myogenic proteins, and mitigated H2O2-induced mitochondrial membrane depolarization in the myoblast cells. In the animal study, 75, 150, and 300 mg/kg bw LI80020F4 doses significantly (P < 0.05) increased the animals' forelimb grip strength. Mid- and high-dose groups showed increased swimming time, increased muscle weight, CSA, muscle growth-related, and mitochondrial protein expressions in the GA muscles. Conclusion LI80020F4 increases nitric oxide production in the endothelial cells, mitochondrial biogenesis and function, upregulates skeletal muscle growth-related protein expressions and reduces oxidative stress; together, it explains the basis of the ergogenic potential of LI80020F4.

Cytotoxicity Analysis and In Silico Studies of Three Plant Extracts with Potential Application in Treatment of Endothelial Dysfunction. Pharmaceutics 2023; 15:2125. [PMID: 37631338 PMCID: PMC10459174 DOI: 10.3390/pharmaceutics15082125] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 08/06/2023] [Accepted: 08/09/2023] [Indexed: 08/27/2023] Open
Abstract
Endothelial dysfunction is the basis of the physiopathological mechanisms of vascular diseases. In addition to the therapeutic activity of plant extracts, cytotoxicity is significant. This research evaluates the cytotoxicity of three vegetal extracts (Calendulae flos extract-CE, Ginkgo bilobae folium extract-GE, and Sophorae flos extract-SE). In vitro evaluation was performed using an endothelial cell line model (Human Pulmonary Artery Endothelial Cells-HPAEC) when a dose-dependent cytotoxic activity was observed after 72 h. The IC50 values were calculated for all extracts: Calendulae flos extract (IC50 = 91.36 μg/mL), Sophorae flos extract (IC50 = 68.61 μg/mL), and Ginkgo bilobae folium extract (IC50 = 13.08 μg/mL). Therefore, at the level of HPAEC cells, the cytotoxicity of the extracts follows the order GE > SE > CE. The apoptotic mechanism implied in cell death was predicted for several phytocompounds using the PASS algorithm and molecular docking simulations, highlighting potential interactions with caspases-3 and -8. In vivo analysis was performed through brine shrimp lethality assay (BSLA) when lethal, behavioral, and cytological effects were evaluated on Artemia salina larvae. The viability examined after 24 h (assessment of lethal effects) follows the same sequence: CE > SE > GE. In addition, the predicted cell permeability was observed mainly for GE constituents through in silico studies. However, the extracts can be considered nontoxic according to Clarckson's criteria because no BSL% was registered at 1200 µg/mL. The obtained data reveal that all three extracts are safe for human use and suitable for incorporation in further pharmaceutical formulations.

Abstract
Endothelial dysfunction is an early complication of diabetes and it is related to both micro- and macroangiopathies. In addition, >70% of diabetic patients develop autonomic neuropathies. Increased oxidative stress has a major role in the development of both nitrergic and endothelial dysfunction. The aim of this work is to evaluate whether rutin, a potent antioxidant, could ameliorate nitrergic and/or endothelial dysfunction in diabetic animals. Primary and secondary treatment protocols with rutin were investigated on rat aortic rings and the mesenteric arteriolar bed, and on rabbit aortic rings and corpora cavernosa (RbCC) from both euglycemic and alloxan-diabetic animals. Acetylcholine endothelium-dependent and sodium nitroprusside endothelium-independent relaxations were compared in tissues from euglycemic or diabetic animals. Electrical field stimulation (EFS)-induced relaxation was performed only in the RbCC. Endothelial-dependent relaxations were blunted by 40% in vessels and neuronal relaxation was blunted by 50% in RbCC taken from diabetic animals when compared to euglycemic animals. Pre-treatment with rutin restored both neuronal and endothelial dependent relaxations in diabetic animals towards the values achieved in control euglycemic tissues. Rutin was able to ameliorate both endothelial dysfunction and nitrergic neuropathy in animal experimental models. Rutin could be a lead compound in the primary or secondary preventive ancillary treatment of endothelial and nitrergic dysfunction in the course of diabetes.

Pulegone Prevents Hypertension through Activation of Muscarinic Receptors and Cyclooxygenase Pathway in L-NAME-Induced Hypertensive Rats. Cardiovasc Ther 2023; 2023:8166840. [PMID: 37214130 PMCID: PMC10195173 DOI: 10.1155/2023/8166840] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 02/23/2023] [Accepted: 02/27/2023] [Indexed: 05/24/2023] Open
Abstract
The current study was designed to determine pulegone's antihypertensive and vasoprotective activity in L-NAME-induced hypertensive rats. Firstly, the hypotensive dose-response relationship of pulegone was evaluated in normotensive anesthetized rats using the invasive method. Secondly, the mechanism involved in hypotensive activity was determined in the presence of pharmacological drugs such as atropine/muscarinic receptor blocker (1 mg/kg), L-NAME/NOS inhibitor (20 mg/kg), and indomethacin/COX inhibitor (5 mg/kg) in anesthetized rats. Furthermore, studies were carried out to assess the preventive effect of pulegone in L-NAME-induced hypertensive rats. Hypertension was induced in rats by administering L-NAME (40 mg/kg) orally for 28 days. Rats were divided into six groups which were treated orally with tween 80 (placebo), captopril (10 mg/kg), and different doses of pulegone (20 mg/kg, 40 mg/kg, and 80 mg/kg). Blood pressure, urine volume, sodium, and body weight were monitored weekly. After 28 days, the effect of pulegone on lipid profile, hepatic markers, antioxidant enzymes, and nitric oxide was estimated from the serum of treated rats. Moreover, plasma mRNA expression of eNOS, ACE, ICAM1, and EDN1 was measured using real-time PCR. Results show that pulegone dose-dependently decreased blood pressure and heart rate in normotensive rats, with the highest effect at 30 mg/kg/i.v. The hypotensive effect of pulegone was reduced in the presence of atropine and indomethacin, whereas L-NAME did not change its hypotensive effect. Concurrent treatment with pulegone for four weeks in L-NAME-treated rats caused a reduction in both systolic blood pressure and heart rate, reversed the reduced levels of serum nitric oxide (NO), and ameliorated lipid profile and oxidative stress markers. Treatment with pulegone also improved the vascular response to acetylcholine. Plasma mRNA expression of eNOS was reduced, whereas ACE, ICAM1, and EDN1 levels were high in the L-NAME group, which was facilitated by pulegone treatment. To conclude, pulegone prevented L-NAME-induced hypertension by demonstrating a hypotensive effect through muscarinic receptors and cyclooxygenase pathway, indicating its use as a potential candidate in managing hypertension.

An integrated strategy for anti-inflammatory quality markers screening of traditional Chinese herbal medicine Mume Fructus based on phytochemical analysis and anti-colitis activity. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 99:154002. [PMID: 35231824 DOI: 10.1016/j.phymed.2022.154002] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 01/24/2022] [Accepted: 02/15/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Mume Fructus (MF) is used in traditional Chinese herbal medicine (TCM) to treat chronic cough, prolonged diarrhea, and other inflammation-related diseases. It is processed from Prunus mume fruit (PM) by drying at low temperature according to the Chinese Pharmacopoeia. The standard quality control method includes measurement of citric acid content, which is not sufficient to determine its clinical efficacy. In addition, the quality markers, that would ensure consistent drug composition and stability during extraction and processing of the drug, are currently not available. PURPOSE This study sought to determine and analyze the bioactive compounds in MF and to establish the quality maker evaluation system, which would enable accurate assessment of different processing and extraction approaches for MF preparation. STUDY DESIGN AND METHODS First, a UPLC-QTOF-MS/MS method was established to identify the chemical constituents of PM and MF. Second, the 2,4,6-trinitrobenzenesulfonic acid (TNBS)-treated rats were used to assess anti-inflammatory activity of water and ethanol extracts of PM and MF. Third, correlation analysis and multivariate statistical analysis was used to seek the candidate quality markers of MF. Fourth, molecular docking was used to predict the potential mechanism of identified compounds for the anti-inflammatory activity. Finally, a UPLC method was established to quantify the selected quality markers in MF products, that were prepared by different drying processes. RESULTS 99 components (28 newly reported) were identified from PM and MF. During the drying process several changes in the composition were observed; caffeoylquinic acids were degraded to p-coumaric acid, caffeic acid, protocatechuic acid, or p-hydroxybenzoic acid; multi-acetyl p-coumaroyl sucroses were degraded to mumeose R and p-coumaroyl-3-O-sucrose. On the other hand, contents of mumefural and amygdalin increased after drying process. In colitis rats, MF reduced more NO levels to greater extent in comparison to PM, which could be attributed to the presence of caffeic acid, p-coumaric acid, protocatechuic acid, p-hydroxybenzoic acid, mumefural, p-coumaroyl-3-O-sucrose, mumeose R, and amygdalin in MF. Moreover, water extracts were better than ethanol extracts in alleviating the IL-1β, IL-6, and IL-17 levels, possibly on account of citric acid and caffeoylquinic acids. The predicted mechanism of action could be through inhibition of the production of NLRP3, TLR4, and NF-κB proteins. Finally, 7 compounds (citric acid, 3-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, caffeic acid, protocatechuic acid, and p-coumaric acid) were selected as quality markers of MF that could be used for the process quality control. CONCLUSION This study revealed the material basis of PM and MF for anti-colitis activity and discovered the quality markers of MF which could reflect the anti-inflammatory activity and the processing process of MF.

Abstract
Atherosclerosis, as a chronic inflammatory response, is one of the main causes of cardiovascular diseases. Atherosclerosis is induced by endothelial cell dysfunction, migration and proliferation of smooth muscle cells, accumulation of foam cells and inflammatory response, resulting in plaque accumulation, narrowing and hardening of the artery wall, and ultimately leading to myocardial infarction or sudden death and other serious consequences. Flavonoid is a kind of natural polyphenol compound widely existing in fruits with various structures, mainly including flavonols, flavones, flavanones, flavanols, anthocyanins, isoflavones, and chalcone, etc. Because of its potential health benefits, it is now used in supplements, cosmetics and medicines, and researchers are increasingly paying attention to its role in atherosclerosis. In this paper, we will focus on several important nodes in the development of atherosclerotic disease, including endothelial cell dysfunction, smooth muscle cell migration and proliferation, foam cell accumulation and inflammatory response. At the same time, through the classification of flavonoids from fruits, the role and potential mechanism of flavonoids in atherosclerosis were reviewed, providing a certain direction for the development of fruit flavonoids in the treatment of atherosclerosis drugs.

Inhibition of α-Glucosidase, Acetylcholinesterase, and Nitric Oxide Production by Phytochemicals Isolated from Millettia speciosa—In Vitro and Molecular Docking Studies. PLANTS 2022; 11:plants11030388. [PMID: 35161369 PMCID: PMC8840612 DOI: 10.3390/plants11030388] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 01/28/2022] [Accepted: 01/28/2022] [Indexed: 02/07/2023]
Abstract
The phytochemical constituents from the roots of Millettia speciosa were investigated by chromatographic isolation, and their chemical structures were characterized using the MS and NMR spectroscopic methods. A total of 10 compounds, including six triterpenoids, two flavonoids, and two phenolic compounds, were identified from the roots of M. speciosa. Out of the isolated compounds, eight showed inhibitory effects on NO production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells, with IC50 values ranging from 43.9 to 449.5 µg/mL. Ursane-type triterpenes significantly suppressed NO production compared to the remaining compounds. In addition, these compounds also exhibited remarkable inhibitory effects on α-glucosidase. Among the tested compounds, 4, 5, and 10 exhibited excellent α-glucosidase inhibition, with IC50 values ranging from 1.1 to 2.2 µg/mL. Almost all of the test compounds showed little or no acetylcholinesterase inhibition, except for 5, which showed moderate anti-acetylcholinesterase activity in vitro. The molecular docking study of α-glucosidase inhibition by 3–5 and 10 was conducted to observe the interactions of these molecules with the enzyme. Compounds 4, 5, and 10 exhibited a better binding affinity toward the targeted receptor and the H-bond interactions located at the entrance of the enzyme active site pocket in comparison to those of 3 and the positive control acarbose. Our findings evidence the pharmacological potential of this species and suggest that the phytochemicals derived from the roots of M. speciosa may be promising lead molecules for further studies on the development of anti-inflammatory and anti-diabetes drugs.

Abstract
Metabolic syndrome (MetS) belongs to the serious health complications expanding in cardiovascular diseases, obesity, insulin resistance, and hyperglycemia. In this study, hypertriacylglycerolemic rats fed a high-fat-fructose diet (HFFD) were used as an experimental model of MetS to explore the effect of tested compounds. Effects of a new prospective pyridoindole derivative coded SMe1EC2 and the natural polyphenol rutin were tested. Endothelial nitric oxide synthase (NOS3) and nuclear factor kappa B (NF-?B) expression were assessed in the left ventricle immunohistochemically and left ventricle activity was monitored in isolated perfused rat hearts. NOS3 activity in the left ventricle decreased markedly as a result of a HFFD. NOS3 expression was upregulated by both substances. NF-?B expression was increased in the MetS group in comparison to control rats and the expression further increased in the SMe1EC2 treatment. This compound significantly improved the coronary flow in comparison to the control group during reperfusion of the heart followed after ischemia. Further, it tended to increase left ventricular systolic pressure, heart product, rate of maximal contraction and relaxation, and coronary flow during baseline assessment. Moreover, the compound SMe1EC2 decreased the sensitivity of hearts to electrically induced ventricular fibrillation. Contrary to this rutin decreased coronary flow in reperfusion. Present results suggest that despite upregulation of NOS3 by both substances tested, pyridoindole SMe1EC2 rather than rutin could be suitable in treatment strategies of cardiovascular disorders in MetS-like conditions.

Abstract
It is well known that both Fagopyrum esculentum species, buckwheat achenes and buckwheat germs, contain flavonoids, and that they can be considered functional foods. In the present study we have analyzed the total content of polyphenols (TPC) and flavonoids (TFC), as well as the antioxidant activity of buckwheat ahcenes originating from the Balti region, Republic of Moldova, and also of the buckwheat sprouts over seven days of germination. The content of phytochemicals in achenes and germinated buckwheat after three and seven days was determined by HPLC–MS analysis. Using the Folin–Ciocalteu method, we recorded an increase in TPC of 360%, and of 436% in TFC after seven days of buckwheat ahcene germination. We aimed to investigate the free radical scavenging properties of methanolic extracts from ahcenes and sprouted buckwheat. We identified and quantified flavonoids and lignans such as rutin, orientin, isoorientin, vitexin, quercetin, quercitrin, isorhamnetin, lutein, apigenin, catechins, coumestrol—which have countless beneficial effects on human health—using HPLC–MS. FTIR analysis also revealed the accumulation of phenolic compounds during germination. This is the first study on the identification and quantification of phytochemicals from buckwheat achenes and sprouts from the Balti region of the Republic of Moldova.

Abstract
Cardiovascular diseases (CVD) constitute the major cause of death worldwide and show a higher prevalence in the adult population. The human umbilical cord consistsof two arteries and one vein, both composed of three tunics. The tunica intima, lined with endothelial cells, regulates vascular tone through the production/release of vasoregulatory substances. These substances can be vasoactive factors released by endothelial cells (ECs) that cause vasodilation (NO, PGI2, EDHF, and Bradykinin) or vasoconstriction (ET1, TXA2, and Ang II) depending on the cell type (ECs or SMC) that reacts to the stimulus. Vascular studies using ECs are important for the analysis of cardiovascular diseases since endothelial dysfunction is an important CVD risk factor. In this paper, we will address the morphological characteristics of the human umbilical cord and its component vessels. the constitution of the vascular endothelium, and the evolution of human umbilical cord-derived endothelial cells when isolated. Moreover, the role played by the endothelium in the vasomotor tone regulation, and how it may be associated with the existence of CVD, were discussed.

Abstract
Drug-eluting stents (DES) have been widely used for the treatment of cardiovascular diseases. Nevertheless, chronic inflammation and delayed re-endothelialization still represent challenges for their clinical use. In the present work, we developed novel bilayer coatings for stent applications that could overcome these limitations, exclusively using biodegradable plant-based drugs and polymers. In particular, stainless steel surfaces were coated with rutin-loaded zein (the active layer) and cross-linked alginate (the sacrificial layer) via facile dip and spray coating methods. Various mechanical tests and analysis tools, such as infrared spectroscopy, water contact angle measurements, and scanning electron microscopy were used to characterize the coated surfaces. Degradation and release studies of the films were extensively carried out and compared. The release rate of rutin from the bilayer coating reached 66.1 ± 3.2% within 24 hours of incubation (initial burst period), while the rest of the drug was released over 21 days in a sustained manner. Antioxidant assays confirmed that rutin retained its free radical scavenging ability after being eluted in phosphate buffer at 37 °C. In vitro results with human fibroblasts and endothelial cells suggested that the coating materials and their degradation products are highly biocompatible.

Liu R, Guan S, Gao Z, Wang J, Xu J, Hao Z, Zhang Y, Yang S, Guo Z, Yang J, Shao H, Chang B. Pathological Hyperinsulinemia and Hyperglycemia in the Impaired Glucose Tolerance Stage Mediate Endothelial Dysfunction Through miR-21, PTEN/AKT/eNOS, and MARK/ET-1 Pathways. Front Endocrinol (Lausanne) 2021; 12:644159. [PMID: 33967958 PMCID: PMC8104127 DOI: 10.3389/fendo.2021.644159] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Accepted: 04/06/2021] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Impaired glucose tolerance (IGT) is an important prediabetic stage characterized by elevated concentrations of glucose and insulin in the blood. The pathological hyperglycemia and hyperinsulinemia in IGT may regulate the expression of microRNA-21 (miR-21) and affect the downstream insulin signaling pathways, leading to endothelial cell dysfunction and early renal damage. METHODS The individual and combined effects of insulin and glucose were investigated using human glomerular endothelial cells (HGECs). The expression levels of miR-21, and PTEN/AKT/eNOS and MAPK/ET-1 pathway proteins in the treated cells were measured. The levels of nitric oxide (NO) and endothelin-1 (ET-1) secreted by the cells were also measured. The role of miR-21 in mediating the regulatory effects of insulin and glucose was assessed by overexpression/inhibition of this miRNA using mimics/inhibitor. RESULTS High (>16.7 mmol/L) concentration of glucose upregulated the expression of miR-21, leading to the activation and inhibition of the PTEN/AKT/eNOS and MAPK/ET-1 pathways, and upregulation of NO and downregulation of ET-1 secretion, respectively. High (>25 ng/mL) concentration of insulin downregulated the expression of miR-21, and lead to the activation of the MAPK/ET-1 and inhibition of the PTEN/AKT/eNOS pathway, thereby upregulating the expression of ET-1 and downregulating the secretion of NO. MiR-21 was observed to play a key role by directly controlling the activation of the insulin signaling pathways when the cells were cotreated with different concentrations of insulin and glucose. The expression of miR-21 was found to be dependent on the relative concentration of insulin and glucose. Under simulated conditions of the IGT stage (8.3 mmol/L glucose + 50 ng/mL insulin), the inhibitory effect of high insulin concentration on miR-21 expression in the cells attenuated the activation by high glucose concentration, resulting in the downregulation of miR-21, upregulation of ET-1 and downregulation of NO secretion. CONCLUSION Taken together, these results indicate that high insulin and glucose concentrations regulate the secretory function of glomerular endothelial cells in opposite ways by regulating the expression of miRNA-21. Pathological concentrations of insulin and glucose in the IGT stage may lead to a decrease in miR-21 expression, thereby disordering the secretion of vasoactive factors, resulting in renal tubule ischemia.

Abstract
BACKGROUND Rutin as a natural flavonoid compound has revealed an extensive range of therapeutic potentials. PURPOSE The current paper is focused on the numerous studies on rutin nanoformulations regarding its broad spectrum of therapeutic potentials. STUDY AND METHODS A review was conducted in electronic databases (PubMed) to identify relevant published literature in English. No restrictions on publication date were imposed. RESULTS The literature search provided 7,078 results for rutin. Among them, 25 papers were related to the potential biological activities of rutin nanoformulations. Polymeric nanoparticles were the most studied nanoformulations for rutin (14 titles) and lipid nanoparticles (5 titles) were in second place. The reviewed literature showed that rutin has been used as an antimicrobial, antifungal, and anti-allergic agent. Improving the bioavailability of rutin using novel drug-delivery methods will help the investigators to use its useful effects in the treatment of various chronic human diseases. CONCLUSION It can be concluded that the preparation of rutin nanomaterials for the various therapeutic objects confirmed the enhanced aqueous solubility as well as enhanced efficacy compared to conventional delivery of rutin. However, more investigations should be conducted to confirm the improved bioavailability of the rutin nanoformulations.

Abstract
Multiple dysregulated signaling pathways are implicated in the pathogenesis of cancer. The conventional therapies used in cancer prevention/treatment suffer from low efficacy, considerable toxicity, and high cost. Hence, the discovery and development of novel multi-targeted agents to attenuate the dysregulated signaling in cancer is of great importance. In recent decades, phytochemicals from dietary and medicinal plants have been successfully introduced as alternative anticancer agents due to their ability to modulate numerous oncogenic and oncosuppressive signaling pathways. Rutin (also known as rutoside, quercetin-3-O-rutinoside and sophorin) is an active plant-derived flavonoid that is widely distributed in various vegetables, fruits, and medicinal plants, including asparagus, buckwheat, apricots, apples, cherries, grapes, grapefruit, plums, oranges, and tea. Rutin has been shown to target various inflammatory, apoptotic, autophagic, and angiogenic signaling mediators, including nuclear factor-κB, tumor necrosis factor-α, interleukins, light chain 3/Beclin, B cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein, caspases, and vascular endothelial growth factor. A comprehensive and critical analysis of the anticancer potential of rutin and associated molecular targets amongst various cancer types has not been performed previously. Accordingly, the purpose of this review is to present an up-to-date and critical evaluation of multiple cellular and molecular mechanisms through which the anticancer effects of rutin are known to be exerted. The current challenges and limitations as well as future directions of research are also discussed.

Anti-Hypertensive Activity of Novel Peptides Identified from Olive Flounder ( Paralichthys olivaceus) Surimi. Foods 2020; 9:foods9050647.

Abstract
There is a growing interest in the health benefits of functional foods. A benefit that has been long sought is the control of hypertension through dietary approaches. Hypertension has been implicated as a risk factor for cardiovascular disease and is therefore of clinical significance. Here, we aim to demonstrate the antihypertensive activity of novel peptides derived from surimi, a functional food ingredient made from refined fish myofibrillar proteins. Three peptides, Ile-Val-Asp-Arg (IVDR), Trp-Tyr-Lys (WYK), and Val-Ala-Ser-Val-Ile (VASVI), were isolated from surimi made from the olive flounder (Paralichthys olivaceus). Our results show that IVDR, WYK, and VASVI exhibited high Angiotensin I-converting Enzyme (ACE) inhibition activity. These peptides are also shown to increase phosphorylation of protein kinase B (Akt) and endothelial nitric oxide synthase (eNOS), and significantly promote nitric oxide (NO) production in human umbilical vein endothelial cells. Oral administration of the peptides decreased blood pressure in spontaneously hypertensive rats (SHRs), thereby confirming that the peptides derived from surimi perform antihypertensive activity via the Akt/eNOS pathway. These results indicate that surimi made from P. olivaceus contains novel antihypertensive peptides that could be used to enhance the health benefits of food ingredients.

The granulopoietic cytokine granulocyte colony-stimulating factor (G-CSF) induces pain: analgesia by rutin. Inflammopharmacology 2019; 27:1285-1296.

Abstract
Rutin is a glycone form of the flavonol quercetin and it reduces inflammatory pain in animal models. Therapy with granulocyte colony-stimulating factor (G-CSF) is known by the pain caused as its main side effect. The effect of rutin and its mechanisms of action were evaluated in a model of hyperalgesia induced by G-CSF in mice. The mechanical hyperalgesia induced by G-CSF was reduced by treatment with rutin in a dose-dependent manner. Treatment with both rutin + morphine or rutin + indomethacin, at doses that are ineffectual per se, significantly reduced the pain caused by G-CSF. The nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG)-ATP-sensitive potassium channel (KATP) signaling pathway activation is one of the analgesic mechanisms of rutin. Rutin also reduced the pro-hyperalgesic and increased anti-hyperalgesic cytokine production induced by G-CSF. Furthermore, rutin inhibited the activation of the nuclear factor kappa-light-chain enhancer of activated B cells (NFκB), which might explain the inhibition of the cytokine production. Treatment with rutin upregulated the decreased mRNA expression of the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) combined with enhancement of the mRNA expression of the Nrf2 downstream target heme oxygenase (HO-1). Intraperitoneal (i.p.) treatment with rutin did not alter the mobilization of neutrophils induced by G-CSF. The analgesia by rutin can be explained by: NO-cGMP-PKG-KATP channel signaling activation, inhibition of NFκB and triggering the Nrf2/HO-1 pathway. The present study demonstrates rutin as a promising pharmacological approach to treat the pain induced by G-CSF without impairing its primary therapeutic benefit of mobilizing hematopoietic progenitor cells into the blood.

Abstract
Sodium fluoride is one of the neglected environmental contaminants. Inorganic fluorides in the environment are found in the air, water, and land. In the study, forty-male Wistar albino rats were randomly divided into four groups with 10 rats in a group. Group A was the control group which was given normal saline, Group B was exposed to 300 ppm of NaF in drinking water, while Groups C and D received NaF along Rutin (100 mg/kg and 200 mg/kg) orally daily for a week. Administration of NaF alone led to significant increases in blood pressure, and deceased serum nitric oxide. Immunohistochemistry revealed higher expressions of kidney injury molecule I (Kim-1), nuclear factor kappa beta (NF-κB), and down regulation of nuclear factor erythroid 2-related factor 2 (Nrf2) in rats administered NaF. Rutin co-treatment with NaF normalized blood pressure, lowered Kim-1 and NF-κB expressions, and improved nitric oxide bioavailability.

Abstract
BACKGROUND Cisplatin (CP) or cis-diammine dichloroplatinum (II) is a platinum based standard antineoplastic drug which is used against variety of solid tumors and neoplasms. The present study aimed to evaluate the shielding effects of rutin against CP induced testicular toxicity in rats. METHODS 28 male rats were divided into four groups. First group was given saline orally while second group received intra-peritoneal (i.p) injection of cisplatin (7 mg/kg) on day first and received saline for next 13 days. Third group received i.p injection of cisplatin at day one and treated with rutin (75 mg/kg) orally for next 13 days. Fourth group was treated with rutin orally for 13 days. Animals were sacrificed on 14th day and reproductive organs were analyzed for various parameters. RESULTS Cisplatin treatment resulted in a significant decrease in daily sperm production, decrease in head length and % DNA in head, reduction of epithelial cell height, tubular diameter, reduction of the number of spermatogonia, spermatocytes and spermatids, increase in the thiobarbituric acid reactive substances (TBARS) and oxidative stress in testicular tissues, and change of the intra-testicular testosterone concentrations. Rutin co-treatment resulted in reversing cisplatin effect on DNA damage, sperm count, histological and biochemical parameters. CONCLUSION These results indicated that rutin co-treatment could ameliorate cisplatin-induced reproductive toxicity in male rats.

Abstract
BACKGROUND Neurovascular dysfunction caused by traumatic brain injury (TBI) is characterized by cerebralvascular damage, blood-brain barrier (BBB) breakdown, brain edema, etc. This study was designed to assess the protective role of 5 days troxerutin cerebroprotein hydrolysate (TCH) injection treatment against TBI, as well as the potential mechanism. METHODS The weight-drop model of TBI in male Sprague-Dawley rats was chosen to induce TBI model, rats either with TCH or a vehicle via intraperitoneal injection were examined 3 days after TBI. RESULTS TCH resulted in alleviation of neurological deficits, reduction of infarct volume, improvement of regional cerebral blood flow (rCBF), amelioration of neuronal death, astrocyte proliferation, endothelial cell loss, and BBB dysintegrity. These effects of TCH treatment against TBI were through endothelial nitric oxide synthase (eNOS) coupling/decoupling status adjustment, which not only increased nitric oxide (NO) level, but also decreased peroxynitrate level expression. CONCLUSIONS All the results indicated that TCH injection has multifaceted protective effects of neurovascular unit (NVU) against TBI via eNOS pathway regulation.

Abstract
Objectives Inflammation plays a key role in the pathogenesis of atherosclerosis. Piper sarmentosum is an herb with antioxidant and anti-atherosclerotic activities. The aim of this study was to evaluate the anti-inflammatory properties of an aqueous extract of P. sarmentosum (AEPS) in human umbilical vein endothelial cells (HUVECs). Methods HUVECs were divided into six groups: control, treatment with 10 ng/ml TNF-α, and co-treatment of 10 ng/ml TNF-α with four different concentrations of AEPS (100, 150, 250, and 300 μg/ml) for 24 h. Subsequently, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) protein expression, U937 monocyte cells adhesion, and nuclear factor-kappaB (NF-κB) p65 expression in HUVECs were measured. Results Treatment of TNF-α-stimulated HUVECs with AEPS at different concentrations resulted in decreased VCAM-1 and ICAM-1 protein expression in a dose-dependent manner. Furthermore, AEPS also inhibited TNF-α-stimulated U937 monocyte cells adhesion to HUVECs. In addition, AEPS reduced TNF-α-induced NF-κB p65 expression in a dose-dependent manner. Conclusions The results indicated that AEPS suppressed TNF-α-induced VCAM-1 and ICAM-1 expression NF-κB signaling. Piper sarmentosum attenuates VCAM-1 and ICAM-1 expression in TNF-α-induced HUVEC. P. sarmentosum inhibits TNF-α-stimulated monocytes adhesion to HUVEC. P. sarmentosum reduces TNF-α-induced NF-κB p65 expression in HUVEC.

Abstract
Rutin, a natural bioflavonoid, has demonstrated anti-diabetic and anti-oxidative bioactivity. Oxidative stress is a potential therapeutic target for diabetic cardiomyopathy. We investigated whether rutinadministration (60mg/kg body weight) reduces diabetic cardiomyopathy in a diabetic ApoE knock out mouse model. Diabetes was induced in ApoEknockout mice (male, C57BL/6 background) with a high fat diet combined with injection of streptozotocin. Cardiac function was evaluated by echocardiography and cardiac catheter hemodynamic analysis. Cardiac myocardial hypertrophy, myocardial fibrosis, lipid content, myocardial capillary density, and oxidative stress were detected by a series of histopathological analyses, western blotting, and reactive oxygen species analysis. Diabetic mice showed myocardial hypertrophy, lipid accumulation, myocardial fibrosis, elevated collagen content, deteriorating oxidative stress, and left ventricular systolic and diastolic dysfunction. Rutin reversed the myocardial hypertrophy, alleviated extracellular collagen deposition, and lipid accumulation, but increased capillary density in diabetic myocardial tissues. Moreover, rutin substantially improved cardiac function while decreasing blood glucose and lipid content. Therapeutic rutin administration reduced cardiac remodeling and improved myocardial function in diabetic mice, at least in part by reducing oxidative damage and ectopic lipid deposition, inhibiting fibrosis, and promoting angiogenesis. Thus, rutin may represent a potential therapeutic agent for diabetic cardiomyopathy.

Abstract
Rutin, also called rutoside or quercetin-3-O-rutinoside and sophorin, is a glycoside between the flavonol quercetin and the disaccharide rutinose. Although many effects of rutin have been reported in vitro and in vivo, the anti-adipogenic effects of rutin have not been fully reported. The aim of this study was to confirm how rutin regulates adipocyte related factors. In this study, rutin decreased the expressions of adipogenesis-related genes, including peroxisome proliferators, activated receptor [Formula: see text] (PPAR[Formula: see text], CCAAT/enhancer-binding protein [Formula: see text] (C/EBP[Formula: see text], fatty acid synthase, adipocyte fatty acid-binding protein, and lipoprotein lipase in 3T3-L1 cells. Rutin also repressed the expression of lipin1, which is an upstream regulator that controls PPAR[Formula: see text] and C/EBP[Formula: see text]. In addition, when 3T3-L1 was transfected with lipin1 siRNA to block lipin1 function, rutin did not affect the expressions of PPAR[Formula: see text] and C/EBP[Formula: see text]. These results suggest that rutin has an anti-adipogenic effect that acts through the suppression of lipin1, as well as PPAR[Formula: see text] and C/EBP[Formula: see text].

Abstract
OBJECTIVES Rutin, quercetin-3-O-rutinoside, a natural flavonol glycoside, has shown various in vitro benefits with potential use treating human diseases, especially cardiovascular system disorders. Antioxidant properties are assumed to underlie the majority of these benefits. Yet rutin pro-oxidant properties have been reported as well. Our research group has recently shown aggravating effects on isoprenaline (ISO)-induced cardiotoxicity in Wistar:Han rats after 24 hours. METHODS This study was designed to examine in more detail the reasons for the negative effects of rutin (11.5 and 46 mg/kg, i.v.) after administration of ISO (100 mg/kg, s.c.) in rats within 2 hours of continuous experiment and in the H9c2 cardiomyoblast-derived cell line. RESULTS Like our previous findings, rutin did not (11.5 or 46 mg/kg, i.v.) reduce the ISO-induced mortality within 2 hours although the lower dose significantly reduced cardiac troponin T (cTnT) and partly improved the histological findings. In contrast, the higher dose increased the mortality in comparison with solvent (1.26% w/v sodium bicarbonate). This was not caused by any specific haemodynamic disturbances. It appears to be associated with oxidative stress as rutin enhanced intracellular reactive oxygen species formation in vitro and had the tendency to increase it in vivo. CONCLUSIONS Rutin, likely due to its pro-oxidative effects, can exacerbate catecholamine cardiotoxicity depending on the dose used.

Exp Mol Med 2015; 47:e171.

Abstract
Pentraxin 3 (PTX3) was identified as a marker of the inflammatory response and overexpressed in various tissues and cells related to cardiovascular disease. Honokiol, an active component isolated from the Chinese medicinal herb Magnolia officinalis, was shown to have a variety of pharmacological activities. In the present study, we aimed to investigate the effects of honokiol on palmitic acid (PA)-induced dysfunction of human umbilical vein endothelial cells (HUVECs) and to elucidate potential regulatory mechanisms in this atherosclerotic cell model. Our results showed that PA significantly accelerated the expression of PTX3 in HUVECs through the IκB kinase (IKK)/IκB/nuclear factor-κB (NF-κB) pathway, reduced cell viability, induced cell apoptosis and triggered the inflammatory response. Knockdown of PTX3 supported cell growth and prevented apoptosis by blocking PA-inducted nitric oxide (NO) overproduction. Honokiol significantly suppressed the overexpression of PTX3 in PA-inducted HUVECs by inhibiting IκB phosphorylation and the expression of two NF-κB subunits (p50 and p65) in the IKK/IκB/NF-κB signaling pathway. Furthermore, honokiol reduced endothelial cell injury and apoptosis by regulating the expression of inducible NO synthase and endothelial NO synthase, as well as the generation of NO. Honokiol showed an anti-inflammatory effect in PA-inducted HUVECs by significantly inhibiting the generation of interleukin-6 (IL-6), IL-8 and monocyte chemoattractant protein-1. In summary, honokiol repaired endothelial dysfunction by suppressing PTX3 overexpression in an atherosclerotic cell model. PTX3 may be a potential therapeutic target for atherosclerosis.

Abstract
Human endothelial basement membrane (BM) plays a pivotal role in vascular development and homeostasis. Here, a bioresponsive film with dual-microstructured geometries was engineered to mimic the structural roles of the endothelial BM in developing vessels, for vascular tissue engineering (TE) application. Flexible poly(ε-caprolactone) (PCL) thin film was fabricated with microscale anisotropic ridges/grooves and through-holes using a combination of uniaxial thermal stretching and direct laser perforation, respectively. Through optimizing the interhole distance, human mesenchymal stem cells (MSCs) cultured on the PCL film's ridges/grooves obtained an intact cell alignment efficiency. With prolonged culturing for 8 days, these cells formed aligned cell multilayers as found in native tunica media. By coculturing human umbilical vein endothelial cells (HUVECs) on the opposite side of the film, HUVECs were observed to build up transmural interdigitation cell-cell contact with MSCs via the through-holes, leading to a rapid endothelialization on the PCL film surface. Furthermore, vascular tissue construction based on the PCL film showed enhanced bioactivity with an elevated total nitric oxide level as compared to single MSCs or HUVECs culturing and indirect MSCs/HUVECs coculturing systems. These results suggested that the dual-microstructured porous and anisotropic film could simulate the structural roles of endothelial BM for vascular reconstruction, with aligned stromal cell multilayers, rapid endothelialization, and direct cell-cell interaction between the engineered stromal and endothelial components. This study has implications of recapitulating endothelial BM architecture for the de novo design of vascular TE scaffolds.
