The predominant reactions from both eukaryotic and prokaryotic biocatalysts were stereoselective epoxide opening and chemical and regio- and stereoselective double bond reduction, though the fungi were more efficient than the bacteria. Substrates and six selected metabolites were subjected to <i>in vitro</i> evaluation for antiproliferative effects against six human solid tumor cell lines. The derivative 3<i>α</i>,4<i>β</i>-dihydroxy-estafietin showed significant activity against HBL-100, HeLa, and SW1573 cell lines, justifying a more specific, in-depth evaluation of its scope as an anticancer candidate molecule.</p>","PeriodicalId":20127,"journal":{"name":"Planta medica","volume":" ","pages":"655-664"},"PeriodicalIF":2.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146011798","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}
