Abstract
The study presents a significant advancement in drug delivery and therapeutic efficacy through the successful synthesis of Gliricidia sepium(Jacq.) Kunth. ex. Walp., stem zinc oxide nanoparticles(GSS ZnONPs). The phenolic compounds present in Gliricidia sepium stem (GSS) particularly vanillic acid, apegnin-7-O-glucoside, syringic acid, and p-coumaric acid which were identified by HPLC. These compounds shown antioxidant and anti-inflammatory properties. GSS ZnONPs demonstrate pronounced gastroprotective effects against ethanol-induced gastritis, evidenced by the reduction in gastric lesions and mucosal injury upon its treatment. Histopathological evaluation and immunohistochemical analysis of nuclear factor erythroid 2-related factor 2 (Nrf2) expression further validate these results, revealing the amelioration of ethanol-induced gastritis and improved gastric tissue condition due to their treatment. Noteworthy is the dose-dependent response of GSS ZnONPs, showcasing their efficacy even at lower doses against ethanol-induced gastritis which is confirmed by different biomarkers. These findings have substantial implications for mitigating dosage-related adverse effects while preserving therapeutic benefits, offering a more favorable treatment approach. This study aims to investigate the potential gastroprotective activity of GSS ZnONPs against gastritis.

Sweet on Alleviation of Potassium Dichromate-Induced Pulmonary Damage in Rats. PLANTS (BASEL, SWITZERLAND) 2024; 13:338. [PMID: 38337870 PMCID: PMC10857331 DOI: 10.3390/plants13030338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/08/2024] [Accepted: 01/19/2024] [Indexed: 02/12/2024]
Abstract
Maesa indica (Roxb.) Sweet is one of the well-known traditionally-used Indian plants. This plant is rich in secondary metabolites like phenolic acids, flavonoids, alkaloids, glycosides, saponins, and carbohydrates. It contains numerous therapeutically active compounds like palmitic acid, chrysophanol, glyceryl palmitate, stigmasterol, β-sitosterol, dodecane, maesaquinone, quercetin 3-rhaminoside, rutin, chlorogenic acid, catechin, quercetin, nitrendipine, 2,3-dihydroxypropyl octadeca-9,12-dienoate, kiritiquinon, and β-thujone. The Maesa indica plant has been reported to have many biological properties including antidiabetic, anticancer, anti-angiogenic, anti-leishmanial, antioxidant, radical scavenging, antibacterial, antiviral, and anti-coronavirus effects. One purpose of the current study was to investigate the leaves' metabolome via Triple-Time-of-Flight-Liquid-Chromatography-Mass Spectrometry (T-TOF LC/MS/MS) to identify the chemical constituents of the Maesa indica ethanolic extract (ME). Another purpose of this study was to explore the protective effect of ME against potassium dichromate (PD)-induced pulmonary damage in rats. Rats were assigned randomly into four experimental groups. Two different doses of the plant extract, (25 and 50 mg/kg), were administered orally for seven consecutive days before PD instillation injection. Results of our study revealed that ME enhanced cellular redox status as it decreased lipid peroxidation marker, MDA and elevated reduced glutathione (GSH). In addition, ME upregulated the cytoprotective signaling pathway PI3K/AKT. Moreover, ME administration ameliorated histopathological anomalies induced by PD. Several identified metabolites, such as chlorogenic acid, quercetin, apigenin, kaempferol, luteolin, and rutin, had previously indicated lung-protective effects, possibly through an antioxidant effect and inhibition of oxidative stress and inflammatory mediators. In conclusion, our results indicated that ME possesses lung-protective effects, which may be the result of its antioxidant and anti-inflammatory properties.

Fundam Clin Pharmacol 2023; 37:947-959. [PMID: 36977287 DOI: 10.1111/fcp.12895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 02/24/2023] [Accepted: 03/17/2023] [Indexed: 03/30/2023]
Abstract
Adenosine monophosphate kinase/liver kinase B1/peroxisome proliferator-activated receptor-γ coactivator 1-α (AMPK/LKB1/PGC1α) pathway has a vital role in regulating age-related diseases. It controls neurogenesis, cell proliferation, axon outgrowth, and cellular energy homeostasis. AMPK pathway also regulates mitochondrial synthesis. The current study evaluated the effect of chrysin on D-galactose (D-gal) induced-aging, neuron degeneration, mitochondrial dysfunction, oxidative stress, and neuroinflammation in mice. The mice were allocated randomly into four groups (10 each group): Group 1: normal control group, Group 2: D-gal group, Groups 3 and 4: chrysin (125 and 250 mg/kg, respectively). Groups 2-4 were injected with D-gal (200 mg/kg/day; s.c) for 8 weeks to induce aging. Groups 3 and 4 were orally gavaged every day concurrent with D-gal. At the end of experiment, behavioral, brain biochemical and histopathological changes were monitored. Chrysin administration elevated discrimination ratio in object recognition, Y Maze percentage alternation, locomotor activity and brain contents of AMPK, LKB1, PGC1α, NAD (P)H quinone oxidoreductase 1 (NQO1), heme oxygenase 1 (HO-1), nerve growth factor (NGF) (neurotrophin-3; NT-3), and seretonin as well as reduced brain contents of tumor necrosis factor-alpha (TNF-α), nuclear factor kappa B (NF-κB), advanced glycation end products (AGEs) and glial fibrillary acidic protein (GFAP) compared to D-gal-treated mice. Chrysin also alleviated cerebral cortex and white matter neurons degeneration. Chrysin protects against neurodegeneration, improves mitochondrial autophagy and biogenesis as well as activates antioxidant genes expression. In addition, chrysin ameliorates neuroinflammation and stimulates the release of NGF and serotonin neurotransmitter. So, chrysin has a neuroprotective effect in D-gal induced-aging in mice.

Abstract
Cyclophosphamide (CP) is a chemotherapeutic agent that causes pulmonary damage by generating free radicals and pro-inflammatory cytokines. Pulmonary damage has a high mortality rate due to the severe inflammation and edema occurred in lung. PPARγ/Sirt 1 signaling has been shown to be cytoprotective effect against cellular inflammatory stress and oxidative injury. Protocatechuic acid (PCA) is a potent Sirt1 activator and exhibits antioxidant as well as anti-inflammatory properties. The current study aims to investigate the therapeutic impacts of PCA against CP-induced pulmonary damage in rats. Rats were assigned randomly into 4 experimental groups. The control group was injected with a single i.p injection of saline. CP group was injected with a single i.p injection of CP (200 mg/kg). PCA groups were administered orally with PCA (50 and 100 mg/kg; p.o.) once daily for 10 consecutive days after CP injection. PCA treatment resulted in a significant decrease in the protein levels of MDA, a marker of lipid peroxidation, NO and MPO along with a significant increase in GSH and catalase protein levels. Moreover, PCA downregulated anti-inflammatory markers as IL-17, NF-κB, IKBKB, COX-2, TNF-α, and PKC and upregulated cytoprotective defenses as PPARγ, and SIRT1. In addition, PCA administration ameliorated FoxO-1 elevation, increased Nrf2 gene expression, and reduced air alveoli emphysema, bronchiolar epithelium hyperplasia and inflammatory cell infiltration induced by CP. PCA might represent a promising adjuvant to prevent pulmonary damage in patients receiving CP due to its antioxidant and anti-inflammatory effects with cytoprotective defenses.

Abstract
OBJECTIVE Fenofibrate (FNF), an anti-hyperlipidemic agent, suffers from poor water solubility (0.000707mg/ml) and belongs to class II drug as per BCS, shows a slow dissolution rate. The current investigation aimed to fabricate a fast-dissolving tablet of FNF (not available in the commercial market) using solid dispersion technique employing Vitamin E-D-α-Tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS) as molecular biomaterial to enhance dissolution rate and reduce the time required to reach the systemic circulation. MATERIALS AND METHODS Firstly, carrier material was selected based on the release study via preparing solid dispersion using the melting method, and prepared solid dispersion was characterized. Secondly, fast-dissolving tablets from solid dispersion were fabricated using the direct compression tool and characterized for X-ray diffraction (XRD) pattern, friability, hardness, content uniformity, weight variation and in vitro disintegration test. RESULTS The X-ray diffraction study confirmed the successful formation of solid dispersion using vitamin E TPGS by analyzing the change in physical state. The fabricated solid dispersion exhibited higher drug content than a physical mixture of FNF. An excipient interference study was also performed in methanol and 0.75% w/v sodium lauryl sulphate. It revealed no significant alterations in the absorption peak of FNF as analyzed using UV spectroscopy at 287nm. In addition, water absorption ratio phase solubility and wetting time were also assessed. In -vitro release of FNF from developed tablets was found significantly higher (93.23%±3.11; p<0.001) as compared to prepared compressed tablet of pure FNF (12.21±2.34%). The dissolution rate was also determined, and data were then kept to various kinetic models such as zero-order chemical kinetic, first-order chemical kinetic, Hixon-Crowell and Higuchi chemical kinetic. CONCLUSION A complete and sequential in vitro and physicochemical characterization of developed formulation was carried out to set-up improved and effective treatment for high blood cholesterol.

Abstract
AIM Aging is the leading risk factor for diminishing lung function, as well as injury and lung disorder. The target of our research was to examine the potential protective effect of naringin and the possible role of SIRT1 in mice with D-galactose-induced lung aging, by evaluating its effects on antioxidant systems, mitochondrial biogenesis, autophagy, and apoptosis, by referring to the potential involvement of Nrf2/NQO1, LKB1/AMPK/PGC-1α, FOXO1, and P53/caspase-3 signaling. MATERIAL AND METHODS The mice were randomly sorted into 5 groups (10 each): 1st: normal group received subcutaneous normal saline and intragastric distilled water, 2nd: naringin 300 mg/kg orally, 3rd: D-galactose (200 mg/kg/day) was administered subcutaneously into mice for eight weeks, to accelerate aging, 4th & 5th: oral naringin (150, 300 mg/kg) was given daily concurrently with D-galactose injection for 8 weeks. KEY FINDING In silico investigation revealed that naringin substantially stimulates the SIRT1 and AMPK molecules. At the molecular level, our findings indicated that treatment with naringin stimulated the mitochondrial biogenesis pathway through regulation of the LKB1/AMPK/PGC-1α signals and upregulated FOXO1-mediated autophagy. Furthermore, naringin exhibited antioxidant properties by activating the Nrf2/NQO1 pathway and inhibiting MDA and AGEs levels. In addition, Naringin ameliorated alveolar spaces destruction and bronchial wall thickening, as well as alleviated P53/caspase-3 apoptosis signaling. SIGNIFICANCE Naringin exerts protective effects against D-galactose-induced lung aging and enhances longevity by activating SIRT1. SIRT1 regulates various aging-related molecular pathways via restoring pro-oxidant/antioxidant homeostasis, activation of mitochondrial biogenesis, modulating of autophagy and inhibition of apoptosis.

Abstract
Background: Carpet dust exposure in the carpet industry causes various respiratory hazards that lead to permanent loss of lung function. This study investigated the potentially toxic effects of knotted and tufted carpet dust on rat lungs and the possible involvement of cytochrome P450 2E1 (CYP2E1) and extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathways in the induced toxicity, as well as histological changes in the lung induced by carpet dust.Methods: This study divided 48 adult rats into six groups: group I was the control group, group II (vehicle group) received phosphate buffer saline (50 µL/rat), groups III and IV received knotted dust (2.5 and 5 mg/kg, respectively), and groups V and VI received tufted dust (2.5 and 5 mg/kg, respectively). All treatments were intranasally administered once a day for 7 days.Results: Both dust types significantly decreased the lung content of GSH compared with the control. Significantly elevated malondialdehyde (MDA) and nitric oxide (NO) lung contents were observed with an increased CYP2E1, interleukin (IL)-6, nuclear factor kappa B (NF-κβ), and ERK/MAPK. The histological lung structure was moderately affected with a moderately increased number of CD68-positive macrophages in the lung parenchyma of knotted dust-exposed rats, whereas tufted dust exposure severely affected the lung tissue with significantly increased CD68-positive macrophages.Conclusions: Carpet dust exposure could induce oxidative stress and inflammatory response in the lung tissue via induction of CYP2E1 that stimulates ERK/MAPK signalling pathway proteins, resulting in elevated MDA, NO and IL-6 levels in the lung tissue with suppressed GSH content. Tufted dust could possess a more toxic response than knotted ones.

Amorphous Solid Dispersion of Hesperidin with Polymer Excipients for Enhanced Apparent Solubility as a More Effective Approach to the Treatment of Civilization Diseases. Int J Mol Sci 2022; 23:ijms232315198. [PMID: 36499518 PMCID: PMC9740072 DOI: 10.3390/ijms232315198] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/26/2022] [Accepted: 11/30/2022] [Indexed: 12/11/2022] Open
Abstract
The present study reports amorphous solid dispersions (ASDs) of hesperidin (Hes) prepared by ball milling to improve its solubility and apparent solubility over the unmodified compound. The carriers were Soluplus® (Sol), alginate sodium (SA), and hydroxypropylmethylcellulose (HPMC). XRPD analysis confirmed full amorphization of all binary systems in 1:5 w/w ratio. One glass transition (Tg) observed in DSC thermograms of hesperidin:Soluplus® (Hes:Sol) and hesperidin:HPMC (Hes:HPMC) 1:5 w/w systems confirmed complete miscibility. The mathematical model (Gordon-Taylor equation) indicates that the obtained amorphous systems are characterized by weak interactions. The FT-IR results confirmed that hydrogen bonds are responsible for stabilizing the amorphous state of Hes. Stability studies indicate that the strength of these bonds is insufficient to maintain the amorphous state of Hes under stress conditions (25 °C and 60 °C 76.4% RH). HPLC analysis suggested that the absence of degradation products indicates safe hesperidin delivery systems. The solubility and apparent solubility were increased in all media (water, phosphate buffer pH 6.8 and HCl (0.1 N)) compared to the pure compound. Our study showed that all obtained ASDs are promising systems for Hes delivery, wherein Hes:Sol 1:5 w/w has the best solubility (about 300-fold in each media) and apparent solubility (about 70% in phosphate buffer pH 6.8 and 63% in HCl).

Abstract
Famotidine (FMD) is a highly potent H2-receptor antagonist used in peptic ulcer treatment. However, the drug possesses poor aqueous solubility and permeability. FMD-loaded solid self-nanoemulsifying drug delivery system (FMD-S-SNEDDS) comprised of Labrafil® M 1944 CS, Tween® 20 and PEG 400, adsorbed on Aerosil® 200, has been developed. FMD-S-SNEDDS has demonstrated acceptable micromeritic properties, and upon reconstitution in water, spherical nanosized particles were released, as demonstrated by dynamic light scattering studies and transmission electron microscopy imaging. High encapsulation efficiency of FMD in the developed SNEDDS has been attained, and the saturated solubility of the drug has increased by 20-fold when it was incorporated in the SNEDDS. Several in vitro characterizations have been carried out, including, Fourier transform-infrared spectroscopy, differential scanning calorimetry, scanning electron microscopy, and drug dissolution studies. In vivo, upon administration of the free drug suspension, marketed product (FAMOTIN®) and FMD-S-SNEDDS (40 mg/kg) in peptic ulcer rat models, FMD-S-SNEDDS and the marketed FMD demonstrated 12.5- and 4.7-fold reduction in ulcers number, and 28.7- and 7.2-fold reduction in ulcer severity, respectively, compared to the control untreated animals. FMD-S-SNEDDS showed a significant (p < 0.05) increase in the levels of depleted glutathione and endothelial nitric oxide synthase, and significantly (p < 0.05) reduced the elevated level of malondialdehyde, as compared to the free and marketed FMD. Only FMD-S-SNEDDS could restore the elevated proton pump activity and cyclic adenosine monophosphate RNA expression to their normal levels. Hence, FMD-S-SNEDDS provides a great potential as a nanotherapeutic system for treatment of peptic ulcer.

Abstract
The functional behaviour of tablets is strongly influenced by their manufacturing process and the choice of excipients. Water uptake and swelling are prerequisites for tablet disintegration, dispersion and hence active pharmaceutical ingredient (API) dissolution. High proportions of polymeric excipients in tablets, which are typically used as API carriers in amorphous solid dispersions (ASDs), may be challenging due to the formation of a gelling polymer network (GPN). In this study, systematic investigations into the formulation development of tablets containing polymeric and other excipients are performed by water uptake and swelling analysis. The impact of tablet composition and porosity as well as pH of the test medium are investigated. The pH affects the analysis results for Eudragit L100-55 and Eudragit EPO. HPMC and Kollidon VA64 inhibit water uptake and swelling of tablets due to the formation of a GPN. High tablet porosity, coarse particle size of the polymer and the addition of fillers and disintegrants can reduce the negative impact of a GPN on tablet performance. The application of lubricants slows down the analysed processes. Water uptake and swelling data are fitted to an empirical model obtaining four characteristic parameters to facilitate the simple quantitative assessment of varying tablet formulations and structural properties.

A review of emerging technologies enabling improved solid oral dosage form manufacturing and processing. Adv Drug Deliv Rev 2021; 178:113840. [PMID: 34147533 DOI: 10.1016/j.addr.2021.113840] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 06/08/2021] [Accepted: 06/14/2021] [Indexed: 12/20/2022]
Abstract
Tablets are the most widely utilized solid oral dosage forms because of the advantages of self-administration, stability, ease of handling, transportation, and good patient compliance. Over time, extensive advances have been made in tableting technology. This review aims to provide an insight about the advances in tablet excipients, manufacturing, analytical techniques and deployment of Quality by Design (QbD). Various excipients offering novel functionalities such as solubility enhancement, super-disintegration, taste masking and drug release modifications have been developed. Furthermore, co-processed multifunctional ready-to-use excipients, particularly for tablet dosage forms, have benefitted manufacturing with shorter processing times. Advances in granulation methods, including moist, thermal adhesion, steam, melt, freeze, foam, reverse wet and pneumatic dry granulation, have been proposed to improve product and process performance. Furthermore, methods for particle engineering including hot melt extrusion, extrusion-spheronization, injection molding, spray drying / congealing, co-precipitation and nanotechnology-based approaches have been employed to produce robust tablet formulations. A wide range of tableting technologies including rapidly disintegrating, matrix, tablet-in-tablet, tablet-in-capsule, multilayer tablets and multiparticulate systems have been developed to achieve customized formulation performance. In addition to conventional invasive characterization methods, novel techniques based on laser, tomography, fluorescence, spectroscopy and acoustic approaches have been developed to assess the physical-mechanical attributes of tablet formulations in a non- or minimally invasive manner. Conventional UV-Visible spectroscopy method has been improved (e.g. fiber-optic probes and UV imaging-based approaches) to efficiently record the dissolution profile of tablet formulations. Numerous modifications in tableting presses have also been made to aid machine product changeover, cleaning, and enhance efficiency and productivity. Various process analytical technologies have been employed to track the formulation properties and critical process parameters. These advances will contribute to a strategy for robust tablet dosage forms with excellent performance attributes.

L-carnitine alleviated acute lung injuries induced by potassium dichromate in rats: involvement of Nrf2/HO-1 signaling pathway. Heliyon 2021; 7:e07207. [PMID: 34169163 PMCID: PMC8207205 DOI: 10.1016/j.heliyon.2021.e07207] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 05/22/2021] [Accepted: 06/01/2021] [Indexed: 12/25/2022] Open
Abstract
The activation of the Nrf2/HO-1 signaling pathway regulates cellular antioxidant stress and exerts anti-inflammatory and cytoprotective effects against acute lung injury (ALI). The present study aimed to evaluate the therapeutic role of L-carnitine (LC) against potassium dichromate (PD) - induced acute lung injury in adult male albino rats via modulation of Nrf2/HO-1 signaling pathway. For this purpose, forty rats were randomly allocated into 5 groups (8 rats each). The normal group received intranasal (i.n.) saline, while the ALI group received intranasal instillation of PD as a single dose of 2 mg/kg. The 3d - 5th groups received PD then after 24 h administered L-carnitine (25, 50 and 100 mg/kg; orally) for 3 consecutive days. The therapeutic effect of L-carnitine was evaluated by assessment of serum levels of glutathione (GSH) and malondialdehyde (MDA) along with measurement of lung contents of transforming growth factor β1 (TGFβ1), protein kinase B (AKT), Nuclear factor erythroid-2 related factor 2 (Nrf2), Kelch-like ECH-associated protein 1 (Keap1), heme oxygenase-1 (HO-1), NAD(P)H quinone oxidoreductase 1 enzyme (NQO1) and glutathione cysteine ligase modifier subunit (GCLM) expression. Post-treatment with L-carnitine effectively increased the levels of GSH and AKT, elevated Nrf2 and its target genes and decreased the levels of MDA and TGFβ1 in comparison with PD control rats. Additionally, L-carnitine effectively reduced the number of goblet cell, inhibited the mucus formation in bronchioles and interstitial inflammatory infiltrate as well as alleviated the destruction of alveolar walls, and the congestion of blood vessels in lung tissue induced by PD. Our findings showed that L-carnitine may be a promising therapeutic agent against PD-induced acute lung injury.

Russelioside B; A pregnane glycoside for treatment of gastric ulcer via modulation of heat shock protein-70 and vascular endothelial growth factor. Steroids 2021; 165:108759. [PMID: 33181144 DOI: 10.1016/j.steroids.2020.108759] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 10/24/2020] [Accepted: 10/29/2020] [Indexed: 12/31/2022]
Abstract
Gastric ulcers are a very common public health problem affecting up to 10% worldwide. Russelioside B is a steroidal glycoside isolated from several Caralluma species. No study tested the ulcer healing potential of the compound. The current study aimed to assess the protective effect of russelioside B against ethanol-induced gastric mucosal injury in rats. Ulcer was induced on rats by a single intragastric dose of absolute ethanol (5 mL/kg). Rats were randomly assorted into four groups (n = 8) and given treatments (Antodine, 20 mg/kg or russelioside B, 50 mg/kg) by oral gavage 1 h before ulcer induction. Pretreatment with russelioside B (50 mg/kg) attenuated the gastric mucosal injury as proved by a decrease of ulcer index, and histological scores. It suppressed the gastric inflammation by a significant lowering the tumor necrosis factor-α and interleukin-6 levels with myeloperoxidase activity (which are also aggravating factors in the case of Covid-19 infection). In addition, administration of russelioside B halted the gastric oxidative stress via inhibition of lipid peroxides by maintaining reduced glutathione and by decreasing malondialdehyde. It was able also to restore the sharp drop in the levels of heat shock protein-70, vascular endothelial growth factor and prostaglandin E2 induced by ethanol. Additionally, it showed carbonic anhydrase inhibition activity. The gastroprotective action of russelioside B was umpired through multi mechanistic actions; suppression of gastric oxidative stress, inflammation, anti-apoptotic activities and enhanced gastric mucosal protection by up-regulation of endothelial growth factor, normalization of heat shock protein-70 and prostaglandin E2. These actions were comparable in part to some classical antiulcer drugs such as Antodine.
