Tirofiban, a reversible glycoprotein IIb/IIIa receptor antagonist, may reduce platelet-mediated rethrombosis and improve reperfusion after thrombolysis. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy and safety of early intravenous tirofiban following IVT. PubMed, Scopus, Web of Science, and the Cochrane Library were searched from inception through May 2026. RCTs comparing early intravenous tirofiban versus standard care or placebo after IVT were included. Outcomes included functional independence (modified Rankin Scale [mRS] 0-2), excellent outcome (mRS 0-1), symptomatic intracranial hemorrhage (sICH), any intracranial hemorrhage (ICH), and 90-day mortality. Risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using random-effects models. Six randomized controlled trials (RCTs) involving 1787 patients were included. Tirofiban significantly increased the likelihood of achieving functional independence at 90 days (RR, 1.14; 95% CI, 1.03-1.25; P = 0.019). Although tirofiban showed a trend toward improving excellent functional outcome, the difference was not statistically significant (RR, 1.21; 95% CI, 0.95-1.56; P = 0.080).

Sensitivity analyses demonstrated robust findings across all outcomes. Early intravenous tirofiban following thrombolysis was associated with improved functional recovery without a significant increase in mortality or intracranial hemorrhage on a relative scale.

Resveratrol (RES), a potent bioactive natural polyphenol, has been shown to effectively alleviate KOA; however, its complex regulatory mechanisms require further investigation. This research seeks to clarify the molecular mechanisms by which RES contributes to the treatment of KOA, utilizing a blend of bioinformatics approaches and experimental validation. First, gene expression profiles related to KOA were obtained from the GEO database. Subsequently, differential gene analysis was conducted on the samples, and modular genes linked to KOA were extracted through the application of a weighted gene co-expression network. The LASSO algorithm was utilized to identify crucial pathogenic genes in KOA, which were later confirmed using clinical samples. Targets for RES were sourced from traditional Chinese medicine databases, and the therapeutic targets for KOA treatment were determined by finding the intersection of these sources. An enrichment analysis was carried out based on the therapeutic targets identified. Molecular docking studies were conducted to further assess the binding affinity of key therapeutic genes with RES. Lastly, animal experiments were implemented to substantiate the molecular mechanisms by which RES acts in the treatment of KOA. We identified 460 module genes and 10 key predictive genes through LASSO analysis. The findings from the enrichment analysis concerning potential therapeutic targets for RES in the treatment of KOA reveal that the significant genes implicated include VEGFA, IL6, MAPK3, IL1B, CASP3, and AKT1. Subsequent validation with clinical samples revealed that IL6, MAPK3, IL1B, CASP3, and AKT1 were significantly elevated during the progression of KOA, while VEGFA was markedly reduced in the context of KOA. The outcomes of the GO and KEGG analyses suggest that the primary biological processes implicated encompass apoptosis, the FoxO signaling pathway, the IL-17 signaling pathway, cellular senescence, and the NF-κB signaling pathway. The findings from the immune infiltration analysis indicate that resting CD4 memory T cells, memory B cells, resting mast cells, eosinophils, and activated mast cells may have important functions in the immune mechanisms related to KOA. The results of animal experiments demonstrate that RES effectively inhibits the expression of inflammatory factors such as IL-6, MAPK3, IL-1β, CASP3, and AKT1 during the progression of KOA, promotes the expression of VEGFA, and concurrently suppresses the FoxO signaling pathway and the IL-17 signaling pathway, thereby reducing cartilage damage induced by MIA and delaying the progression of KOA. In summary, RES can regulate the expression of genes including VEGFA, IL-6, MAPK3, IL-1β, CASP3, and AKT1, inhibit the FoxO signaling pathway and the IL-17 signaling pathway, alleviate cart","PeriodicalId":18876,"journal":{"name":"Naunyn-Schmiedeberg's archives of pharmacology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167587","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}

This study aimed to systematically investigate whether the presence or absence of the C-2,3 double bond affects the efficacy of flavonoids in ameliorating MASLD. Two pairs of C-2,3 positional isomeric flavonoids-eriodictyol (Compound 1a, dihydro form, C-2,3 single bond)/luteolin (Compound 1b, non-dihydro form, C-2,3 double bond) and dihydromyricetin (Compound 2a, dihydro form, C-2,3 single bond)/myricetin (Compound 2b, non-dihydro form, C-2,3 double bond)-were compared using an FFA-induced HepG2 cell model and an HFD-induced MASLD mouse model.

Although formononetin (Fmn), a naturally occurring isoflavone, possesses well-documented antioxidant and anti-inflammatory properties, its protective role and underlying molecular mechanisms in ethanol-induced gastric injury remain unclear. In this study, ethanol-treated GES-1 gastric epithelial cells were used as an in vitro model to investigate the cytoprotective effects of Fmn. Cell proliferation, apoptosis, oxidative stress, and mitochondrial function were evaluated using biochemical and cellular assays. Potential molecular targets were identified through SwissTargetPrediction and molecular docking, followed by experimental validation, including ALDH2 knockdown, qRT-PCR, and enzymatic activity assays. Fmn significantly attenuated ethanol-induced cellular injury by restoring cell proliferation, suppressing apoptosis, reducing intracellular and mitochondrial reactive oxygen species, decreasing malondialdehyde levels, and enhancing superoxide dismutase activity. Molecular docking demonstrated a strong binding affinity between Fmn and aldehyde dehydrogenase 2 (ALDH2), which was further confirmed by increased ALDH2 mRNA and protein expression as well as enhanced enzymatic activity following Fmn treatment. Functional studies revealed that ALDH2 upregulation plays a pivotal role in preserving mitochondrial integrity and limiting oxidative damage. Collectively, these findings demonstrate that Fmn protects gastric epithelial cells against ethanol-induced injury through ALDH2-mediated suppression of oxidative stress and mitochondrial dysfunction, highlighting its potential as a promising therapeutic candidate for the prevention and treatment of alcohol-induced gastric ulceration.</p>","PeriodicalId":18876,"journal":{"name":"Naunyn-Schmiedeberg's archives of pharmacology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149127649","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}

Chronic kidney disease (CKD) is an increasing global health burden, yet the molecular targets potentially linking DEHP exposure to CKD remain incompletely understood. This study integrated epidemiological analysis, network toxicology, Mendelian randomization (MR), molecular docking, and molecular dynamics simulations to investigate potential molecular targets associated with DEHP exposure and CKD. Data from the National Health and Nutrition Examination Survey (NHANES) were used to examine the association between urinary DEHP metabolites and CKD. DEHP-related and CKD-related targets were subsequently integrated to identify shared targets, followed by PPI network analysis and expression-based evaluation to prioritize candidate genes. MR analysis was then performed to assess the association between genetically proxied candidate genes and CKD. Molecular docking was used to explore the potential interactions between DEHP and the prioritized proteins, and molecular dynamics simulations were performed to further evaluate the structural stability of the predicted DEHP-CTSK complex. Higher urinary DEHP metabolite levels were associated with a higher prevalence of CKD. Four candidate genes-CTSK, ABL1, BCL2L1, and CCND1-were prioritized based on network and expression-based analyses. Among these genes, genetically proxied CTSK showed a significant positive association with CKD in the primary MR analysis. Molecular docking showed favorable predicted docking scores for DEHP with the four candidate proteins, while molecular dynamics simulations supported the structural stability of the predicted DEHP-CTSK complex over 100 ns. These findings provide convergent epidemiological, genetic, and computational evidence supporting CTSK as a candidate molecular target for further investigation in the context of DEHP-associated renal injury.</p>","PeriodicalId":18876,"journal":{"name":"Naunyn-Schmiedeberg's archives of pharmacology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149137757","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}
