Sumac liposomes/mesenchymal stem cells fight methotrexate-induced nephrotoxicity in rats via regulating Nrf-2/Keap-1/HO-1 and apoptotic signaling pathways.

Methotrexate (MTX) is commonly employed in cancer treatment, but its clinical use is restricted due to the MTX-associated renal injury. This study investigates the combined potential of Rhus coriaria (sumac) and bone marrow mesenchymal stem cells (BMMSCs) against MTX-induced nephrotoxicity in rats. The high-resolution-liquid chromatography-mass spectrometry (HR-LC-MS) of sumac extract tentatively identified 22 phytochemicals, mostly flavonoids, anthocyanins, and steroids. Preparation of sumac liposomes attained a suitable particle size of 3041.33 ± 339.42 nm, a polydispersity index of 0.208 ± 0.086, and an encapsulation efficiency of 84.92 ± 3.47%. Rat BMMSCs were injected into the tail vein of the experimental rats (0.5 × 106 cells, intravenous [iv]) of seven treated groups. The experimental design relies on either pre- or posttreatment of rats with intraperitoneal (IP) sumac liposomes (SL) (200 mg/kg, daily with a dose of MTX (300 µg/kg/14 days). The histopathological examination and serum analysis of creatinine and urea revealed good results, besides regulating levels of oxidative stress and inflammatory markers. Additionally, a significant decrease in the gene expression levels of B-Cell Lymphoma 2 (Bcl-2) and caspases-3 and -9, a remarkable increase in the Bcl-2 Associated X-Protein (Bax), nuclear factor erythroid 2-related factor 2 (Nrf2), and heme-oxygenase 1 expression, and a downregulation of Kelch-like ECH-associated protein 1 (Keap1). Collectively, the coadministration of SL with BMMSCs might be a potent therapeutic strategy for attenuation of MTX-induced renal damage. The network pharmacology analysis identified the involved key hub genes as KEAP1, Nrf2, HMOX1, mitogen-activated protein kinase (MAPK1), nuclear factor-kappa B (NF-KB), interleukin-1 beta (IL-1B), and caspase-3. The docking results revealed strong binding affinities of 7-O-methyl-cyanidin-3-O-(2″-galloyl)-galactoside with Keap1 and amentoflavone with MAPK. These insights pave the way for future experimental validation and therapeutic development of sumac-based phytoconstituents against MTX-induced nephrotoxicity.

Identification of Active Ingredients in Ginseng Volatile Oil: A Strategy Combining Computer Virtual Screening With Experimental Validation.

Ginseng volatile oil (GVO) is a valuable active ingredient in ginseng (Panax ginseng C. A. Mey.) with high research potential. Drying procedures alter the real composition of the fresh material, for example, the evaporation of compounds with low boiling point. In this study, the composition of volatile oil in fresh ginseng (FG), sun-dried ginseng (SDG), and red ginseng (RD) was systematically analyzed to clarify the dominant components of FG and their potential pharmacological effects, which provides a basis for application and development of FG. GVO was obtained through water vapor distillation and analyzed using GC-MS. Pattern recognition analysis was employed to differentiate components in three processed types of ginseng. Based on this analysis, the active ingredients and key targets were screened. The binding mode and affinity were verified using molecular docking technology. Finally, the anticancer activity of GVO was verified by cell experiments. A total of 53 components were identified in three processed types of ginseng by GC-MS. Among them, 32 differential components were screened by pattern recognition analysis. Ultimately, 6 active ingredients (panaxydol, nerolidyl acetate, falcarinol, cis-β-farnesene, γ-elemene, and β-elemene) and 15 key targets were determined by network pharmacology analysis. Molecular docking results revealed that β-elemene exhibited a higher affinity with EGFR, ESR1, and ERK2. Cell experiments indicated that GVO promotes apoptosis in cancer cells. This research proposed a strategy that integrated "component detection-virtual multitarget screening-active component prediction-experimental verification" to expedite the identification of active ingredients, providing insights for application of FG and the development of functional products.

Wuzi Yanzong Decoction Ameliorates Oligoasthenozoospermia by Up-Regulating Methyltransferase and Increasing Spata, Bcl, and Pik3 Series Genes Methylation Level.

Wuzi Yanzong decoction (WZYZD) belongs to the traditional formula for treating male infertility caused by oligoasthenozoospermia (OLI). This research aims to elucidate the therapeutic substance basis and potential pharmacological mechanisms of WZYZD in treating OLI. A total of 52 chemical ingredients were identified from WZYZD. HE and TUNEL staining demonstrated that WZYZD can markedly alleviate OLI. Immunofluorescence analysis showed that WZYZD can significantly increase the expression levels of DNMT3 A, PIWIL1, SETDB1, and PRMT5. Methyl capture sequencing proved that WZYZD can markedly upregulate the methylated level of Spata, Bcl, and Pik3 series genes. Network pharmacology analysis proved that WZYZD can ameliorate OLI through BCL-2 and PI3 K-AKT signaling pathways. The immunofluorescence assay of BCL-2 and SPATA18 proved the aforementioned results. The potential mechanism of WZYZD in treating OLI mainly involved recruiting methyltransferase DNMT3 A, PIWIL1, PRMT5, and SETDB1 and increasing the methylation degree of Spata, Bcl, and Pik3 series genes.

Mechanism of traditional drug treatment of cancer-related ascites: through the regulation of IL-6/JAK-STAT3 pathway.

Our clinical observation found that JiJiaoLiHuang Pill (JJLH), a classic traditional Chinese medicine (TCM) formulation, can significantly reduce the abdominal circumference of patients with malignant ascites, increase urine output, and improve the quality of life of patients, with preliminary efficacy. But, the exact mechanism is not yet clear. Based on the above observations, the potential mechanism of action of the treatment was preliminarily explored. We identified active ingredients by constructing a "Chinese medicine ingredient-key target-target" network, and verified them by molecular docking using AutoDock tools and PyMOL. Finally, we conducted preliminary verification of the validated pathways and targets using a mouse model of liver cancer ascites. Network pharmacology analysis obtained the top five active ingredients were quercetin, EUPATIN, kaempferol, Obtucarbamate B, and isorhamnetin and the top five key genes were SRC, HSP90AA1, MAPK1, STAT3, and PIK3CA. Molecular docking showed that all 5 active compounds were closely bound to key target genes (binding energy <-6). The animal experiment results showed that JJLH can significantly reduce abdominal circumference, increase urine output, and exhibit dose-dependent inhibition of the AQP-3/JAK-STAT-3 signaling pathway and the expression of related inflammatory factors. The JJLH potentially inhibits the recurrence of liver cancer malignant ascites through the AQP-3/JAK-STAT-3 pathway and affects the prognosis of MA patients.

MitoQ enhances CYP19A1 expression to stimulate WNT/β-catenin signaling pathway for promoting hair growth in androgenetic alopecia.

Increased sensitivity to androgens and androgen receptors is the underlying cause of androgenetic alopecia (AGA), a hereditary disease. Our study investigated the preventive effects of MitoQ on dihydrotestosterone (DHT)-induced mitochondrial dysfunction and subsequent hair loss from three perspectives: in vivo, in vitro, and network pharmacology. A mouse model of AGA was used to assess the effectiveness of MitoQ intervention. Seventy-five drug targets and 367 disease targets were identified through network pharmacology analysis. Molecular docking analysis revealed that the androgen receptor (AR) and CYP19A1, which are key targets of MitoQ, may play a role in AGA treatment. CYP19A1 expression was downregulated in lesions from patients with AGA compared to healthy scalp tissue, while AR expression was upregulated. Cellular tests of human dermal papilla cells (DPCs) treated with MitoQ revealed that the mRNA and protein expression of AR remained unchanged, but the mRNA expression of CYP19A1 was upregulated. Our experiments also confirmed that CYP19A1 overexpression prevented DHT-induced apoptosis and upregulated the expression levels of WNT3A and β-catenin, whereas increased apoptosis levels and the downregulation of WNT3A and β-catenin due to CYP19A1 knockdown were reduced by MitoQ. We verified that MitoQ enhanced hair growth in DHT-induced hair loss model mice and reversed DHT-induced apoptosis by enhancing the expression of CYP19A1 in DPCs and that MitoQ may act by mediating the WNT/β-catenin pathway. These findings indicate that MitoQ could be a promising intervention for AGA and that CYP19A1 may serve as a valuable therapeutic target for AGA.

Naphthoquinone Derivatives from the Endophytic Fungus Fusarium solani Induce Pancreatic Cancer Cells Apoptosis via Targeting EGFR-Mediated PI3K/Akt Pathway.

Seven new polyketide compounds, four naphthoquinone derivatives, neofusarubins A-D (1, 3, 5, and 18) and three graminin-like compounds, fusofuranones A-C (19-21), together with 14 known naphthoquinone derivatives, were isolated from the solid fermentation of Fusarium solani, an endophytic fungus obtained from medicinal plant as tea, Camellia chrysantha. The structures of new compounds were elucidated based on chemical evidence and spectral data analysis (1D and 2D-NMR, HR-ESI-MS, ECD, SC-XRD). Among the isolated compounds tested, 2-acetonyl-3-methyl-5-hydroxy-7-methoxy-naphthazarin (11) exhibited the most potent inhibitory activity against pancreatic cancer in PANC-1, MiaPaCa-2, and BxPC-3 cells. Network pharmacology analysis revealed that compound 11 inhibited cell proliferation and promotion of apoptosis by targeting epidermal growth factor receptor (EGFR), which were confirmed by cellular thermal shift assay (CETSA), microscale thermophoresis (MST) and EGFR stably knockdown cells model assay, respectively. In addition, molecular mechanism studies in vitro showed that 11 could suppress the growth of pancreatic cancer cells by targeting EGFR and effectively inhibit downstream PI3K/Akt signaling pathway. Collectively, these findings provide a new EGFR targeting natural product for the treatment of pancreatic cancer.

Clitoria ternatea L. (Butterfly Pea) Flower Against Endometrial Pain: Integrating Preliminary In Vivo and In Vitro Experimentations Supported by Network Pharmacology, Molecular Docking, and Molecular Dynamics Simulation Studies

Clitoria ternatea L. (CT) is a perennial herbaceous plant with deep blue flowers native to tropical Asia. This work explores the endometrial pain (EP) regulation of CT flower through a multifaceted approach. Phytochemical screening unveiled the presence of alkaloids, steroids, flavonoids, glycosides, and tannins in CT flower methanolic extract (ME). In the in vitro membrane stabilizing experiment, the ME demonstrated 91.47% suppression of heat-induced hemolysis. Upon carrageenan-induced paw edema assay conducted on male Swiss albino mice at doses of 200 mg/kg and 400 mg/kg, 65.28% and 81.89% inhibition rates, respectively, of paw edema were reported. For the same doses, upon acetic acid-induced-writhing assay, 75.6% and 76.78% inhibition rates, respectively, were observed. For network pharmacology analyses, a protein–protein interaction network was constructed for 92 overlapping gene targets of CT and EP, followed by GO and KEGG pathway enrichment analyses. Network pharmacology-based investigation identified the anti-EP activity of CT to be mostly regulated by the proteins SRC homology, ESR1, and PI3KR1. Physicochemical, pharmacokinetic, and toxicity property predictions for the compounds with stable ligand–target interactions and a molecular dynamics simulation for the highest interacting complex further validated these findings. This work affirmed the anti-EP role of CT flower against EP, suggesting a probable molecular mechanism involved.

Evaluation of the Potential Targets of Shenxian–Shengmai Oral Liquid in Treating Sick Sinus Syndrome Based on Network Pharmacology and Molecular Docking

ABSTRACTShenxian–Shengmai (SXSM) is a Chinese patent medicine used in the treatment of sick sinus syndrome (SSS). However, its active chemical compounds and the underlying molecular mechanisms remain unclear. In this study, we researched the underlying mechanisms of SXSM in treating SSS. We conducted network analysis and molecular docking to identify the small molecules and core targets responsible for the therapeutic efficacy of SXSM on SSS. In vitro experiments were performed to verify the potential therapeutic mechanism. Network pharmacological analysis identified 17 core targets. Among these, BMP4, KCNH2, KCNMA1, and KCNQ1 were identified to be involved in various biological processes, such as the formation and regulation of the cardiac pacemaking system and potassium ion transmembrane transport. The experimental analysis revealed that SXSM could upregulate the expression of the Bmp4/Tbx3/Hcn4 pathway and the expression of Kcnh2, Kcnma1, and Kcnq1 channels, which protected and improved the pacemaking function of pacemaker cells (P cells) and increased the heart rate. These findings provide a scientific basis in the study of the mechanism of traditional Chinese medicine in the treatment of SSS.

Pomegranate Peel Extract Mitigates Diarrhea-Predominant Irritable Bowel Syndromes via MAPK and NF-κB Pathway Modulation in Rats

Background: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common chronic functional gastrointestinal disorder that causes diarrheal and intestinal barrier disruptions. Although pomegranate peel extract (PPE) has been reported for the treatment of diarrheal and intestinal inflammation, its effectiveness and mechanisms specifically for the treatment of IBS-D remain unknown. Objectives: This study aimed to explore the therapeutic effect of PPE on IBS-D and elucidate its underlying mechanisms. Methods: A high-fat diet, restraint stress, and senna gavage were combined to establish a rat model mimicking IBS-D, to evaluate the therapeutic effects of PPE. Network pharmacology analysis, serum medicinal chemistry, and transcriptomics were employed to investigate potential downstream signaling pathways. Findings were further validated through molecular docking and Western blot analysis. Results: The findings revealed that PPE significantly improved the symptoms of IBS-D, ameliorated intestinal inflammation, and promoted intestinal barrier function. The target genes in the MAPK and NF-κB signaling pathways were significantly enriched and down-regulated. Molecular docking and Western blot assays were performed to verify that PPE had a high affinity for the protein candidates in these pathways, and significantly down-regulated the expression of p-IκB, p-p65, p-JNK, p-p38, and p-ERK1/2. Conclusions: The present study is the first to demonstrate that PPE alleviates diarrheal and intestinal damage in IBS-D, potentially by inhibiting MAPK and NF-κB signaling pathways. These findings suggest that PPE may provide a novel therapeutic option for IBS-D.

Anti-Obesity Effects of Adzuki Bean Saponins in Improving Lipid Metabolism Through Reducing Oxidative Stress and Alleviating Mitochondrial Abnormality by Activating the PI3K/Akt/GSK3β/β-Catenin Signaling Pathway

Obesity is a chronic and complex disease defined by the excessive deposition of fat and is highly associated with oxidative stress. Adzuki bean saponins (ABS) showed anti-obesity activity in our previous in vivo study; however, the active saponins of adzuki beans and potential mechanisms are still unclear. This research aims to elucidate the anti-obesity effects of ABS in improving lipid metabolism and oxidative stress, exploring the effective ingredients and potential molecular mechanisms through UHPLC-QE-MS analysis, network pharmacology, bioinformatics, and in vitro experiments both in the 3T3-L1 cell line and HepG2 cell line. The results indicate that ABS can improve intracellular lipid accumulation, adipogenesis, oxidative stress, and mitochondrial damage caused by lipid accumulation including ROS generation, abnormal mitochondrial membrane potential, and ATP disorder. Fifteen saponin components were identified with the UHPLC-QE-MS analysis. The network pharmacology and bioinformatics analyses indicated that the PI3K/Akt signaling pathway is associated with the bioactive effect of ABS. Through Western blotting and immunofluorescence analysis, the anti-obesity effect of ABS is achieved through regulation of the PI3K/Akt/GSK3β/β-catenin signaling pathway and activation of downstream transcription factor c-Myc in the lipid accumulation cell model, and regulation of β-catenin signaling and inhibition of downstream transcription factor C/EBPα in the adipocyte cell model. These results illustrate the biological activity of ABS in improving fat metabolism and oxidative stress by restoring mitochondrial function through β-catenin signaling, the PI3K/Akt/GSK3β/β-catenin signaling pathway, laying the foundation for its further development.

An Integrative Strategy for Discriminating Quality Markers of Tibetan Medicine Chebulae Fructus Based on Multidimensional Feature Network.

Chebulae Fructus (TCF) is a traditional Chinese medicine and Tibetan medicine with high medicinal value, but its quality control indicators still need clarification. In this study, a strategy was proposed to specify the quality markers (Q-markers) of TCF by constructing a multidimensional feature network that includes dimensions of effectiveness, content, traceability, and specificity. Network pharmacology analysis was performed to validate the effectiveness of the chemical constituents in TCF through creating a TCF-component-disease-target-pathway network. By combining fingerprints analysis with UPLC-QTOF-MS, 17 differential components were identified among 19 batches of TCF samples. Serum pharmacochemical analysis on rats identified seven prototype components absorbed into the blood. The scores for the four dimensions were calculated using these identified components as candidates, and a multidimensional feature network based on the "spider-web" model was constructed. Ultimately, chebulinic acid, ellagic acid, chebulagic acid, methyl gallate, gallic acid, chebulic acid, and trigalloylglucose were clarified as Q-markers of TCF. These Q-markers screened out in this study are closely linked to the efficacy of TCF and can serve as indicator components for quality control of TCF.

Oxyberberine Inhibits Hepatic Gluconeogenesis via AMPK-Mediated Suppression of FoxO1 and CRTC2 Signaling Axes.

Oxyberberine (OBB), a natural metabolite of berberine, has been shown to exhibit inhibitory effects on gluconeogenesis in our previous work. This work was designed to investigate the potential effects and underlying mechanisms of OBB on hepatic gluconeogenesis. Our work found that OBB significantly inhibited the expressions of glucose 6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK), and decreased the glucose production in palmitic acid-induced HepG2 cells. Then, AMPK/Akt/FoxO1 and AMPK/CRTC2 signaling pathways were confirmed by transcriptomics and network pharmacology analyses. It was shown that AMPK activation may phosphorylate and promote nuclear exclusion of FoxO1 and CRTC2, two key regulators of hepatic gluconeogenesis transcriptional pathways, resulting in the inhibition of gluconeogenesis under OBB administration. Afterwards, AMPK/Akt/FoxO1, AMPK/CRTC2 signaling pathways were evidenced by western blot, immunoprecipitation and confocal immunofluorescence, and the targeted inhibitor (Compound C) and siRNA of AMPK were applied for further mechanism verification. Moreover, it was found that OBB treatment activated AMPK/Akt/FoxO1 and AMPK/CRTC2 signaling pathways to decrease hepatic gluconeogenesis in db/db mice. Similarly, the invivo inhibitory effects of OBB on gluconeogenesis were also diminished by AMPK inhibition. Our work demonstrated that OBB can inhibit hepatic gluconeogenesis invitro and invivo, and its underlying mechanisms were associated with AMPK-mediated suppression of FoxO1 and CRTC2 signaling axes.

Exploration of Astragaloside IV in multiple organ dysfunction syndrome and hippocampus damage through network pharmacological analysis

Background: This study aims to investigate the potential therapeutic effect of Astragaloside IV on the hippocampus in multiple organ dysfunction syndrome (MODS) and its underlying mechanisms. Methods: Targets related to "Multiple Organ Dysfunction Syndrome," "Hippocampus," and "Astragaloside IV" were collected from the GeneCards database. Co-existing intersection targets were identified using a Venn diagram via the bioinformatics platform. A protein interaction network was constructed using the String database, and core targets were screened with the cytoHubba plug-in of Cytoscape software. GO functional enrichment and KEGG pathway enrichment analyses were performed using the DAVID database, and a "disease-site-drug-key target-KEGG pathway" network map was constructed to reveal the mechanisms of Astragaloside IV. Results: Two intersection targets were identified, and the protein interaction network showed their interactions. GO and KEGG analyses indicated that these targets are mainly involved in biological processes and pathways such as efferocytosis. The "disease-site-drug-key targets-KEGG pathway" network map further clarified that Astragaloside IV may treat MODS by affecting specific signaling pathways. Conclusion: Astragaloside IV may exert a therapeutic effect on the hippocampus in MODS by influencing pathways such as efferocytosis, offering new perspectives and potential targets for future research.

Linarin Identified as a Bioactive Compound of Lycii Cortex Ameliorates Insulin Resistance and Inflammation Through the c-FOS/ARG2 Signaling Axis.

Insulin resistance (IR) is a central pathophysiological process underlying numerous chronic metabolic disorders, including type 2 diabetes and obesity. Lycii Cortex, a widely used traditional Chinese herb, has demonstrated potential benefits in preventing and managing diabetes and IR. Whereas, the specific bioactive compounds responsible for these protective effects and their underlying mechanisms of action remain elusive. This study aimed to identify the bioactive components within Lycii Cortex that contribute to its anti-diabetic effects and to elucidate the molecular mechanisms underlying its beneficial actions on insulin resistance. Network pharmacology and molecular docking analyses were employed to identify the potential active compounds in Lycii Cortex and their corresponding target proteins. An invitro model of IR was established using palmitic acid (PA)-treated HepG2 cells. Cell viability was assessed using the CCK-8 assay, while glucose uptake was evaluated by 2-NBDG staining and extracellular glucose measurement. To validate the invitro findings, an invivo model of obesity-induced IR was established using high-fat diet (HFD)-fed mice. The network pharmacology analysis preliminarily identified 13 candidate chemicals and 10 hub LyC and IR-related genes (LIRRGs). Molecular docking analysis demonstrates that Linarin as the potential active component exhibits the greatest potential to target c-FOS for preventing obesity-induced IR. Enrichment analysis suggested that Linarin-targeted pathways are correlated with inflammation. Invitro experimental validation demonstrated that Linarin was capable of protecting against PA-induced IR in HepG2 cells evidenced by improving glucose uptake ability and reducing extracellular glucose content. Additionally, we found that Linarin ablated PA-induced increase in the expression of c-FOS and inflammatory cytokines. Furthermore, in PA-treated cells, silencing c-FOS markedly improved glucose consumption, and reduced inflammation and Arginase 2 (ARG2) expression. Similarly, as exposure to PA, silencing ARG2 also ameliorated glucose uptake and inflammation, while not affecting c-FOS expression. Invivo experiments further showed that Linarin administration remarkably improved glucose tolerance and insulin sensitivity, and reduced the fat mass and body weight in HFD-induced obese mice. In this study, Linarin has been identified as the bioactive compound of Lycii Cortex to ameliorate obesity-related IR and inflammation through the c-FOS/ARG2 signaling cascade. These findings underscore the therapeutic potential of Linarin and provide valuable insights into developing novel intervention strategies for type 2 diabetes therapy.

Tanshinone IIA Alleviates Pulmonary Fibrosis by Inhibiting Pyroptosis of Alveolar Epithelial Cells Through the MAPK Signaling Pathway.

The current dearth of safe and efficacious pharmaceutical interventions for pulmonary fibrosis (PF) has prompted investigations into alternative treatments. This study aim to investigate the underlying mechanisms of Tanshinone IIA in the treatment of PF. PF was induced in a mouse model by intratracheal infusion of bleomycin (BLM), followed by gavage administration of varying concentrations of Tanshinone IIA. Lung tissue was obtained for pathological slides, proteomic and transcriptomic analyses. The target was predicted and analyzed using network pharmacology. Initially, an invitro model in A549 cells was established by adding BLM, followed by treatment with varying concentrations of Tanshinone IIA. Subsequently, NAC and the ERK inhibitor, U0126, were individually introduced. Treatment with Tanshinone IIA invivo decreased lung tissue lesions. Proteomic, transcriptomic, and network pharmacology analyses suggested that Tanshinone IIA may offer therapeutic benefits for PF by mitigating oxidative stress damage via the MAPK signaling pathway. Invitro studies demonstrated that BLM treatment in A549 cells induced exposure of the N-terminal end of the pyroptosis core protein GSDMD, and elevated oxidative stress levels in A549 cells, concomitant with the upregulation of P-ERK protein expression. Subsequent administration of Tanshinone IIA, NAC, and U0126 reduced the number of A549 cells undergoing pyroptosis, decreased oxidative stress levels, and decreased P-ERK protein expression. These findings suggested that Tanshinone IIA potentially delays the progression of PF. The mechanism of action involves the inhibition of oxidative stress and reduced epithelial cell pyroptosis via the MAPK-related pathway. The findings may provide a new reference for treatment of PF.

Network pharmacology and molecular docking to explore the potential molecular mechanism of chlorogenic acid treatment of oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is a tumor type with a high mortality rate. Chlorogenic acid, abundant in resources and widely utilized in cancer treatments, has seen limited studies regarding its efficacy against OSCC. This paper investigates chlorogenic acid's mechanism in treating OSCC, aiming to guide the development of novel drugs. The study employed network pharmacology, molecular docking, and survival analysis methods. Network pharmacological analysis revealed chlorogenic acid targets 23 OSCC-related proteins, including ESR1, MMP2, MMP9, SRC, MAPK8, MAPK1, CDC42, ERBB2, ATM, and BRAF. Molecular docking simulations indicated that the primary target exhibits significant binding capacity with chlorogenic acid, with MMP9 associated with tumor migration and angiogenesis standing out. Survival analysis demonstrated that the downregulation of most primary targets correlates with improved survival rates in OSCC patients. Enrichment analysis of therapeutic targets highlighted the pivotal role of MAPK-ERK and MAPK-JNK signaling pathways in chlorogenic acid's efficacy against OSCC. This paper predicts chlorogenic acid's potential targets and proposes its molecular mechanism in treating OSCC, offering a theoretical foundation for its application in OSCC treatment. We used traditional Chinese medicine, a disease pharmacology-related information base, and an analysis platform to predict targets. The Cytoscape 3.9.1 and STING databases were used to address common targets for drugs and diseases, establish networks of protein interaction relationships, and screen core targets. Meastro11.5 was used for molecular docking simulation. R4.2.2 was used for survival analysis and joint target enrichment analysis. Network pharmacological analysis identified chlorogenic acid acting on 23 OSCC targets. Molecular docking simulations revealed a strong binding affinity of chlorogenic acid compounds with these targets, particularly MMP9, essential for tumor migration and angiogenesis. Survival analysis indicated that the downregulation of most core targets was correlated with improved OSCC patient survival. Enrichment analysis of therapeutic targets highlighted the critical roles of the MAPK-ERK and MAPK-JNK signaling pathways in the effectiveness of chlorogenic acid against OSCC. This study predicted the potential targets of chlorogenic acid in OSCC treatment and hypothesized its molecular mechanism, offering a theoretical foundation for its use in OSCC therapy.

Pharmacodynamic evaluation and network pharmacology analysis of a novel anti-heat stress Chinese herbal formula

Frequent extreme heat events around the world not only pose a major threat to human health but also cause significant economic losses to the livestock industry. The existing management practices are insufficient to fully prevent heat stress with an urgent need to develop preventive medicines. The aim of this study was to develop an anti-heat stress Chinese herbal formula (CHF) via big data analysis techniques and to evaluate its anti-heat stress effect and mechanism of action via pharmacodynamic evaluation and network pharmacology analysis. Many anti-heat stress CHFs were collected from the Chinese National Knowledge Infrastructure (CNKI) database. Three alternative CHFs were obtained via unsupervised entropy hierarchical clustering analysis, and the most effective CHF against heat stress, Shidi Jieshu decoction (SJD), was obtained by screening in a mouse heat stress model. In dry and hot environments, SJD significantly improved the heat tolerance of AA broilers by 4–6°C. In a humid and hot environment, pretreatment with 2% SJD resulted in 100% survival of Wenchang chickens at high temperatures. The main active ingredients of SJD were identified as muntjacoside E, timosaponin C, macrostemonoside H and mangiferin via ultra-performance liquid chromatography/mass spectrometry (UPLC/MS) and database comparison. The active ingredients of SJD were found to target tumor necrosis factor-α (TNF-α), signal transducer activator of transcription 3 (STAT3) and epidermal growth factor receptor (EGFR). Finally, the safety of the new formulation was assessed in an acute oral toxicity study in rats. The SJDs developed in this study provide a new option for the prevention of heat stress in animal husbandry and offer new insights for further research on anti-heat stress.

Metabolite Profiling and Integrated Network Pharmacology Based Mechanism of Benincasa hispida (Thunb.) Cogn. Fruit Against Non-insulin-Dependent Diabetes Mellitus.

Benincasa hispida (Thunb.) Cogn. (Cucurbitaceae) is an essential food plant in India possessing antihyperglycemic and antihyperlipidemic activities. The objective included comparative estimation of α-glucosidase and α-amylase enzyme inhibition potential of B. hispida fractions prepared by microwave-assisted extraction and prediction of metabolite interaction against non-insulin-dependent diabetes mellitus by metabolite profiling based network pharmacology analysis. A validated microwave-assisted extraction method was employed to obtain different fractions of B. hispida fruits. The invitro enzyme assay was done with p-nitrophenyl-α-D-glucopyranoside and acarbose as standard to evaluate antidiabetic potential. The phytomolecules present in the active fraction wereidentified by UHPLC-QToF-MS/MS analysis. Network pharmacology analysis gave possible gene and disease association, combination synergy network, and predicted probable mechanism of action. The highest enzyme inhibition potential (IC50) was shown by the ethyl acetate fraction (0.546 ± 0.17 mg/mL and 1.134 ± 0.42 mg/mL) compared to acarbose (0.298 ± 0.08 mg/mL and 0.532 ± 0.38 mg/mL), respectively, for α-glucosidase and α-amylase addressing the potential role in ameliorating non-insulin-dependent diabetes mellitus. Metabolite profiling resulted in the identification of 17 metabolites, and a synergy between the identified molecules suggested multimolecule action in the amelioration of non-insulin-dependent diabetes mellitus through insulin resistance pathway, AMPK signaling pathway, PPAR signaling pathway, and PI3K-Akt signaling pathway. Combination synergy of identified molecules was observed through a multitarget approach to manage non-insulin-dependent diabetes mellitus. Polyphenol-enriched fraction of B. hispida fruits and identified phytocompounds ameliorate non-insulin-dependent diabetes mellitus. Thus, enriched extract of B. hispida can be further investigated in order to develop high-quality, safe, and effective products for the management of non-insulin-dependent diabetes mellitus.

Tetrandrine Alleviates Pulmonary Fibrosis by Modulating Lung Microbiota-Derived Metabolism and Ameliorating Alveolar Epithelial Cell Senescence.

Tetrandrine (TET) is a minimally toxic drug extracted from the root of Stephania tetrandra. We previously demonstrated that TET could ameliorate pulmonary fibrosis (PF) by modulating autophagy. However, the mechanism behind TET's protective effects on PF remains unclear. In this study, we utilized 16S rRNA gene sequencing, nontargeted metabolomic analysis, and network pharmacology to identify changes in lung microbiota and metabolites that mediate alveolar epithelial cell senescence in bleomycin (BLM)-induced PF in mice. Additionally, we employed Western blot analysis, RT-PCR, and immunofluorescence staining to investigate the invitro and invivo effects of TET and its influential bacterial metabolites on PF. The TET intervention alleviated PF by regulating the compositions of lung microbial communities (Streptococcus, Micrococcus, Acinetobacter, Altererythrobacter, Atopostipes, Candidatus Cloacimonas, Clostridium sensu stricto 1, Sphingomonas, Listeria, Blautia, and Pseudomonas) and metabolites (3,4-dihydroxyphenylpropionic acid (3,4-DHPPA), 6-Aminonicotinamide, N-acetyl-5-methoxykynuramine, and resiniferatoxin). Through network pharmacological analysis, it was determined that 3,4-DHPPA played a crucial role in alleviating PF by further inhibiting the senescence of alveolar epithelial cells, a finding further validated in exvivo experiments. TET mitigated BLM-induced PF in murine models through the modulation of lung microbiota composition and metabolism. Specifically, TET augmented the level of the microbiota-derived metabolite, 3,4-DHPPA, which in turn attenuated alveolar epithelial cell senescence.

SYNERGISTIC POTENTIAL OF NIGELLA SATIVA L. AND TRIGONELLA FOENUM-GRAECUM: INTEGRATED NETWORK PHARMACOLOGY FOR DIABETIC WOUND HEALING

Objective: Diabetes Mellitus (DM) is a metabolic disorder marked by elevated blood glucose levels, and one of the issues linked to DM involves the development of Diabetic Wounds (DW). DW is susceptible to infection and develops into chronic wounds if not treated properly. This study aimed to investigate the network pharmacology of N. sativa L. and T. foenum-graecum, emphasizing on their potential as DW treatment candidates. Methods: Various databases were used in this study, including PubChem, Dr. Duke's phytochemistry and Ethnobotany, and KNApSAcK Family. Swiss Target Prediction and Way2Drug PASS Online were utilized for biological activity and protein target prediction. The DW pathway's protein-protein interactions were examined with the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, Gene Cards, and STRING databases. STRING was used to predict the metabolite's action. The relationship between metabolites and target proteins was predicted using STITCH, and Cytoscape was used to visualize the network. Result: The results showed that ten active ingredients (five active ingredients in N. sativa L. and five active ingredients in T. foenoem-graecum) contributed to DW healing by affecting Tumor Necrosis Factor (TNF), Interleukin-1beta (IL1B), JUN, Caspase 3 (CASP3), Interleukin-6 (IL-6), Alpha Kinase Threonine-1 (AKT1), Vascular Endothelial Growth Factor-A (VEGFA), and Mitogen-Activated Protein Kinase 3 (MAPK3) genes. Furthermore, the ten active ingredients correlated with twenty-eight intracellular proteins, resulting in a mechanism involving eight DW signalling pathways. Conclusion: Based on network pharmacology analysis, we determine that N. sativa L. and T. foenoem-graecum combination can potentially treat DW.
