To enhance anti-fibrotic activities and decrease their side-effects, 31 novel chalcone derivatives were synthesized and evaluated. Among all the compounds, c31 exhibited the strongest anti-inflammatory activity, and its IC<sub>50</sub> is 3.05 ± 0.12 µM; and it effectively inhibited the activation and proliferation of HSC-T6 cells. Mechanistic studies revealed that c31 inhibits HSC activation by downregulating the expression levels of inflammatory factors, such as TNF-α, IL-6, and IL-1β, and by interfering with NF-κB and JNK signaling pathways. Additionally, c31 inhibited HSC-T6 proliferation and promoted apoptosis by blocking a G2/M phase cell cycle; and it also significantly inhibited HSC-T6 cell migration. In a rat model of CCl₄-induced liver fibrosis, c31 improved pathological symptoms, decreasing collagen deposition, fibrotic protein expression, and ALT and AST levels. Meanwhile, it also reduced the secretion of inflammatory factors, thereby alleviating CCl₄-induced liver fibrosis. In summary, c31 had significant anti-inflammatory and anti-fibrotic effects in both in vivo and in vitro; this indicates c31 has the potential to be used as a therapeutic candidate for hepatic inflammation and fibrosis.</p>","PeriodicalId":708,"journal":{"name":"Molecular Diversity","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147479381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overlapping targets were subjected to protein-protein interaction (PPI) network construction, functional enrichment analysis and molecular docking. We then integrated multi-omics data using ten clustering algorithms to identify the consensus GC subtypes, which were subsequently employed 101 machine learning combinations to develop a consensus benzo[a]pyrene-related signature (CBRS) for GC patients. As a result, we identified seven hub toxicological targets: ALB, HSP90AA1, ESR1, INS, TP53, TNF, and EGFR, underscoring their potential central roles in BaP-driven GC pathogenesis. These targets are enriched in the MAPK, Lipid and atherosclerosis, and PI3K-Akt signaling pathway. The BaP-toxicological classifiers and the CBRS prognostic model could provide useful support for risk stratification and inform personalized therapeutic strategies for GC patients. Molecular docking results suggest that BaP exhibits relatively strong binding affinity with these key toxicological targets, potentially implicating their involvement in BaP-induced gastric cancer toxicity.

Current pharmacological interventions provide only symptomatic relief, highlighting the urgent need for novel therapeutic strategies capable of modifying disease progression. Coumarins, particularly 7-hydroxycoumarin and its synthetic derivatives, have attracted considerable interest due to their broad pharmacological potential, including cholinesterase inhibition, monoamine oxidase (MAO) inhibition, antioxidant, anti-amyloidogenic and metal-chelating activities. This review presents a comprehensive analysis of synthetic 7-hydroxycoumarin derivatives reported over the past 15 years as potential anti-Alzheimer agents, classifying them according to their actions on key pathological hallmarks of AD, such as acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), MAO-B, β-amyloid (Aβ) aggregation, oxidative stress and neuroinflammation. Structure-activity relationship (SAR) analysis reveals that substitutions at the 7-, 3- and 4-positions of the coumarin scaffold critically influence pharmacological potency and selectivity, with aromatic and alkyl amine substitutions generally enhancing enzyme inhibition and neuroprotective effects. Several derivatives exhibited sub-micromolar to nanomolar inhibitory activity against AChE and MAO-B, along with antioxidant and anti-Aβ aggregation properties, supporting their multifunctional behaviour. Overall, this review highlights the therapeutic promise of 7-hydroxycoumarin derivatives as multitarget-directed ligands (MTDLs) and provides valuable insights for the rational design of new lead compounds for Alzheimer's disease.</p>","PeriodicalId":708,"journal":{"name":"Molecular Diversity","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147353289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
