Furthermore, these findings emphasize the potential of these compounds in ongoing drug development efforts.</p>","PeriodicalId":19942,"journal":{"name":"Pharmaceutical Biology","volume":"63 1","pages":"607-644"},"PeriodicalIF":4.8,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12366517/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144874519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
