However, the specific components and mechanisms of its action are still unclear. We screened six kinds of lignans from S. chinensis with high content and found that schisandrol A and schisantherin A had a strong vasorelaxant effect. The purpose of this study was to investigate the relaxation and underlying mechanism of schisandrol A in the isolated thoracic aorta of rats. Materials and Methods Isolated rat endothelium-intact and endothelium-removed thoracic aorta strips were pre-constricted with phenylephrine (PE), and the relaxation of schisandrol A on the strips was observed. Then, the mechanism was explored by pre-incubating the strips with nitric oxide synthetase inhibitor Nɷ-nitro-l-arginine methyl ester (L-NAME), cyclooxygenase inhibitor (indomethacin), potassium channel blockers 4-aminopyridine (4-AP), barium chloride (BaCl2), tetraethylamine (TEA), and glibenclamide, respectively, and changing the calcium concentration in the bath. In addition, expressions of endothelial nitric oxide synthetase (eNOS) mRNA and protein in rat thoracic aorta were detected. Results Schisandrol A induced both endothelium-dependent and endothelium-independent relaxation of isolated thoracic aorta strips of rats, and the mechanism might be related to promoting the synthesis of NO, inhibiting Ca 2+ release from the sarcoplasmic reticulum, and blocking the Ca 2+ channels. Conclusion These discoveries may provide a theoretical basis for the traditional application of S. chinensis to treat cardiovascular disease.","PeriodicalId":19895,"journal":{"name":"Pharmacognosy Magazine","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135730522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose The present study aims to computationally screen the phytochemical constituents of Oldenlandia umbellata Linn against the unique molecular therapeutic targets of osteoporosis and validate the results using Molecular Dynamics (MD) Simulation. Methods The molecular docking analysis of the selected phytoconstituents against the molecular targets were performed using AutoDock 4.2.6 – AutoDock Tools 1.5.6. In addition, the drug likeliness, ADME, bioactivity, and toxicity were predicted using Molinspiration ADMELAB2.0, ProTox-II and Orisis DataWarrior online tools. Molecular Dynamic Simulation studies were performed using WebGRO macromolecular simulation server. Results Molecular docking results and data analysis revealed that deacetylasperuloside possesses good drug-likeness, ADME properties, and bioactive scores and did not indicate any toxicity compared to other phytochemicals exhibiting binding energies below –8.00 Kcal/mol against the targets. Together, the study emphasized that deacetylasperuloside could bind with the molecular targets of osteoporosis, and the lead is a potential therapeutic candidate for osteoporosis treatment. Further, molecular dynamic simulation analysis for 100 ns revealed that the ligand–protein complexes, including glycogen synthase kinase 3β (GSK3β)-deacetylasperuloside and cathepsin K (CTSK)-deacetylasperuloside complexes, were stable and highly compact assessed from their trajectories. Hence, it can be emphasized that deacetylasperuloside could be a potential therapeutic molecule that could inhibit the targets, including GSK3β and CTSK.

At present, there is only one therapeutic drug in China, bromocriptine, and the Chinese herb Prunella vulgaris L.( P. vulgaris)(PV) has shown certain anti-prolactinoma effects in the early stage. We expect to develop a candidate drug against prolactinoma. Materials and Methods First, the extracts of P. vulgaris L.(PVE)were extracted with water, and the cell proliferation test of rat pituitary tumor cells MMQ was checked by the Cell Counting Kit-8 (CCK-8) assay. Then, core targets and correlative pathways were selected by the “protein–protein interaction” (PPI) network and the “PV–Target–Prolactinoma” network. The core targets and main components simulate the binding by molecular docking. Finally, the PVE and MMQ cells were used to verify the results. Results Through the CCK-8 assay, the PVE inhibited the proliferation of MMQ cells. From the network pharmacology, the 21 targets, 9 signaling pathways, and 20 gene ontology (GO) projects were attained ( p < .05). As a result the estrogen receptor α (ESR1), RAC-alpha serine/threonine-protein kinase(AKT1), and mitogen-activated protein kinase 3(MAPK3)were the core targets of protein against prolactinomas, which was in line with western blotting analysis.

However, there is little evidence to suggest that Rutin is associated with CCl 4 -induced hepatotoxicity. In this study, we investigated the effects of Rutin on CCl 4 -induced liver inflammation and discussed in vivo and in vitro mechanisms. Materials and Methods CCl 4 was used to induce liver inflammation, and Rutin was used for intervention in mice. Then the body weight, liver weight, and liver inflammation of all mice were measured. Western blotting and RT-PCR were used to assess TLR4/MyD88/NFκB inflammation signaling pathways and inflammatory gene expression. Finally, TLR4 was activated in primary hepatocytes to verify the above signal pathways. Findings CCl 4 mice developed liver function damage and liver inflammation. Further investigations showed that the inhibitory effects of Si on inflammation were mediated by TLR4/MyD88/NFκB inflammation signaling pathways inhibition. Primary hepatocyte studies also confirmed the participation of these signaling pathways and proteins. Significance Rutin improved CCl 4 -induced liver inflammation.

However, its chemical composition and potential active ingredients were clearly unrevealed, which hindered the elaboration of its material basis functional mechanism and clinical application. Materials and Methods In the study, we developed an integrative ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) method coupled with SCIEX OS software for characterizing the chemical composition in SXC. The data collection was conducted using a Waters UPLCTM HSS T3 (2.1 × 100 mm, 1.8 µm) in a binary elution system. The SCIEX OS software coupled with multivariable processing techniques was used to screen absorbed prototypes in serum after oral administration of SXC. The structural identification of the components was performed by MS/MS fragmentation mechanism. Results A total of 113 components from SXC were tentatively characterized, including 38 saponins, 13 flavonoids, 10 phenylpropanoids, 9 alkaloids, 20 organic acids, and 23 others. Based on the in vitro composition results, 21 absorbed prototypes in rat serum were identified, mainly including alkaloids, flavonoids, phenylpropanoids, and saponins.

It was accepted as a medicinal plant by the World Health Organization in 2002, and it is given a detailed place in the monographs under the name Hyperici herba. In these monographs, the antibacterial, antiviral, antidepressant, protein kinase-C inhibitor, and wound-healing effects of the plant were described. Objectives The aim of this study is to determine the essential oil components in the samples of the H. perforatum L. plant, which is widely grown in the Thrace region in Türkiye. Materials and Methods H. perforatum L. plant growing naturally in the provinces of the Thrace region was collected, and the essential oils of the plant were obtained by using the hydro distillation method after the collected herbs were dried. Chemical content analyses were performed on a gas chromatography-flame ionization detection (GC-FID). Results The main components of the essential oil of the plant are sesquiterpenes (ß-caryophyllene, caryophyllene oxide, β-selinene, α-selinene, β-farnesene, α-amorphene, spathulenol), alcohols (1-tetradecanol, 1-tridecanol, phytol, and alpha cadinol), and fatty acids (pentadecanoic acid, palmitic acid, and 9, 12 octadecadienoic acid). Conclusion This is the first study to determine the chemical composition of essential oil in H. perforatum L. samples collected from the Thrace region in Türkiye. The essential oil content of the plant can be affected by factors such as the developmental stages of the plant (preblooming, flowering stage, and fruiting time), use of fresh or dry plant material, extraction method, genetic parameters, and climate.","PeriodicalId":19895,"journal":{"name":"Pharmacognosy Magazine","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135093857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the effect of Xiegan–Liangxue–Jiedu (XGLXJD) decoction, a traditional Chinese medicine formula, on psoriasis based on network pharmacology, molecular docking, and animal experiments. Materials and Methods A protein–protein interaction (PPI) network was constructed using the overlapping targets of XGLXJD decoction and psoriasis. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using Metascape database. High-performance liquid chromatography (HPLC) was used to investigate the main compounds of XGLXJD decoction. Molecular docking was performed to predict the potential interaction between the main compounds and proteins of interest. A C57 mouse model of psoriasis was established via continuous exposure to imiquimod. Seven days later, the XGLXJD decoction was orally administered at increasing doses for 6 days. The psoriasis area and severity index were calculated. Hematoxylin and eosin staining was used to examine skin morphology. Enzyme-linked immunosorbent assay (ELISA) was used to determine the serum levels of adenylyl cyclase (AC), cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), interleukin-17 (IL-17), and tumor necrosis factor-α (TNF-α). Sucrose preference test and forced swimming test were used to assess depression-like behavior. Immunohistochemical (IHC) staining and immunofluorescence were used to investigate the cAMP-response element binding protein (CREB) signaling pathway. Results Overall, 162 overlapping targets were generated. A total of 398 biological processes, 84 molecular functions, and 47 cellular components were identified via GO analysis, whereas 140 pathways were identified via KEGG pathway analysis. The most notable signaling pathways were cAMP as well as downstream IL-17 and TNF-α signaling pathways. HPLC analysis revealed that the main compounds of XGLXJD decoction were paeoniflorin, isorhamnetin, quercetin, luteolin, kaempferol, and baicalein. The molecular docking assay indicated that the docking energies of the main compounds of XGLXJD decoction to the top hub genes were less than −5 kcal/mol. ELISA revealed that the administration of XGLXJD decoction decreased the levels of pro-inflammatory cytokines (TNF-α and IL-17). Furthermore, the AC, cAMP, and PKA levels were enhanced after its administration. IHC staining demonstrated that the administration of XGLXJD decoction activated the AC–cAMP–PKA–CREB signaling pathway in skin. In addition, it enhanced sucrose preference and forced swimming time percentage. It also enhanced the expression of cAMP and PKA in the hippocampus. Conclusion XGLXJD decoction alleviated psoriasis and depression-like behavior. The AC–cAMP–PKA–CREB signaling pathway may play a crucial role in mediating this effect.","PeriodicalId":19895,"journal":{"name":"Pharmacognosy Magazine","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135480829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim This research reveals the therapeutic potential of thymoquinone (TQ) on DN-induced myocardial infarction (MI) in rats. Materials and Methods Male Sprague–Dawley rats were procured, acclimatized, and divided into four groups of six animals each with feed and water ad libitum. MI was induced in rats with a dose of 25 mg/kg DN by oral gavage and TQ in a dose of 20 mg/kg p.o. for the treatment. After animal sacrifice at the end of the experimental period, serum and heart tissue samples were collected and processed appropriately for various analyses such as changes in the body weight, heart weight, marker enzymes, oxidative markers, non-enzymatic and enzymatic antioxidants, inflammatory cytokines, histopathological studies, and cardiac-specific markers. Results DN-induced toxicity depicted decreased body weight (167.83 ± 4.62), heart weight (0.9 ± 0.06), and heart-to-body weight ratio (0.54 ± 0.03). Also, elevated marker enzymes (147.33 ± 20.85, 407.5 ± 31.3, and 110.67 ± 9.65 for CK-MB, AST, and ALT, respectively), elevated oxidative markers (12.87 ± 1.34, 125.17 ± 9.95, and 80.17 ± 5.78 for serum MDA, heart MDA, and heart GSSG, respectively), decreased enzymatic- and nonenzymatic antioxidants (3.15 ± 0.42, 12.23 ± 1.02, 5.75 ± 0.46, 2.02 ± 0.26, 0.72 ± 0.07, 18.05 ± 1.04, 8.62 ± 0.65, and 45.8 ± 2.43 for SOD, CAT, GST, GPx, heart GSH, serum GSH, vit.E, and vit.C, respectively), damaged cellular architecture, elevated inflammatory cytokines, and cardiac-specific markers were noticed. Discussion TQ significantly reduced the toxicities produced by DN in almost all the above parameters. The beneficial effect of DN could be attributed to the influential effect of DN on cardiac-specific Nrf2/HO1-related pathways.

Background The crab has been used as a traditional medicine and food source in many countries worldwide for a long time, and the crab contains various useful substances such as chitin, protein, calcium carbonate, etc. Materials and Methods All rats were fasted for 24 h and then orally pretreated with saline, Eriocheir sinensis (100 mg/kg), or ranitidine (40 mg/kg). Reflux esophagitis was induced by pylorus and forestomach ligation. Morphological changes in the mucosal damage in the esophagus were analyzed by the ImageJ program. Also, the expression of the inflammatory proteins and cytokine in the esophagus was measured by western blot assay to demonstrate the protective effects of Eriocheir sinensis in reflux esophagitis model. Histological analysis of esophagus was performed by hematoxylin &amp; eosin (H&amp;E) staining. Results In the reflux esophagitis induction group, the esophageal tissue damage caused by the induction of reflux was 60% of the whole. Eriocheir sinensis administration significantly ameliorated esophageal mucosal damage by 40%, also determined by histological evaluation of reflux esophagitis in rats. Eriocheir sinensis was also found to downregulate the expression levels of proteins such as cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), and tight junction protein (claudin-5) compared to the reflux esophagitis induction group. In addition, Eriocheir sinensis markedly attenuated the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and the phosphorylation of the inhibitor of NF-κB (IκBα). Conclusion These results indicated that Eriocheir sinensis suppressed the development of esophagitis and modulated inflammation by regulating NF-κB activation. Based on these findings, we concluded that Eriocheir sinensis can protect the esophageal mucosa from reflux esophagitis.","PeriodicalId":19895,"journal":{"name":"Pharmacognosy Magazine","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135386636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
