In clinical treatment, apart from N-acetylcysteine (NAC), the only approved antidote, there are extremely limited effective intervention measures for APAP-induced hepatotoxicity. Therefore, exploring novel liver-protecting drugs and elucidating their mechanisms of action is of great scientific significance and clinical value. Rosmarinic acid (RA), as a natural polyphenolic compound, has been proven to have significant antioxidant activity. Previous studies have shown that it has a protective effect against drug-induced liver injury. Nevertheless, the precise protective mechanism of RA in APAP-induced acute liver injury (AILI) has not been fully defined. This study was based on an AILI mouse model to systematically explore the liver-protecting effect of RA and its underlying molecular mechanisms. The research results showed that pretreatment with RA could notably mitigate liver pathological injury. It could decrease the activities of ALT and AST in the serum, suppress the liver inflammatory reaction, and reverse the decline in the levels of CAT, T-AOC, SOD, and GSH caused by APAP. Meanwhile, RA could enhance antioxidant defense capabilities by activating the Keap1/Nrf2/HO-1 signaling pathway, regulate the <i>xCT</i>/GPX4 axis to inhibit lipid peroxidation, and thus block the process of ferroptosis. In conclusion, this study confirmed that RA exerts a protective effect against AILI by regulating the Keap1/Nrf2/HO-1 axis to enhance antioxidant capacity and inhibit ferroptosis through the <i>xCT</i>/GPX4 pathway. Our research provides a theoretical basis for RA as a potential therapeutic agent for APAP-induced liver injury.</p>","PeriodicalId":18222,"journal":{"name":"Marine Drugs","volume":"23 7","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12299429/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144708004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite efforts to develop effective therapies, existing treatments require a relatively long duration of therapy to eradicate the pathogen due to its virulence factors, pathogenesis patterns, and ability to enter dormant states. This can lead to a higher risk of treatment failure due to poor patient adherence to the complex regimen. As a result, considerable research is necessary to identify alternative antituberculosis agents. The marine environment, particularly marine-derived fungi, has recently gained interest due to its potential as an abundant source of bioactive natural products. This review covers 19 genera of marine-derived fungi and 139 metabolites, 131 of which exhibit antimycobacterial activity. The integrated dataset pinpoints the fungal genera and chemical classes that most frequently yield potent antimycobacterial hits while simultaneously exposing critical gaps, such as the minimal evaluation of compounds against dormant bacilli and the presence of underexplored ecological niches and fungal genera. Several compounds exhibit potent activity through uncommon mechanisms, including the inhibition of mycobacterial protein tyrosine phosphatases (MptpB/MptpA), protein kinase PknG, ATP synthase and the disruption of mycobacterial DNA via G-quadruplex stabilization. Structure-activity relationship (SAR) trends are highlighted for the most potent agents, illuminating how specific functional groups underpin target engagement and potency. This review also briefly proposes a dereplication strategy and approaches for toxicity mitigation in the exploration of marine-derived fungi's natural products.
