Most of the diterpenoids of Turkish <i>Sideritis</i> species have <i>ent</i>-kaurene skeleton, among them linearol, siderol, 7-<i>epi</i>candicandiol and sideridiol were found to be the main compounds. Exceptionally, labdane, pimarane and beyerene diterpenoids were only found in a few species. For phenolics and flavonoids, only 12 species were investigated until now, and they were found to be rich in phenylethanoid glycosides and flavonoid glycosides. In terms of activity, most of the species were tested for antioxidant activity, followed by antimicrobial and anti-ulcer/anti-inflammatory activities. Their cytotoxic, enzyme inhibitory, antinociceptive and antistress activities were less frequently studied.</p><p><strong>Conclusions: </strong><i>Sideritis</i> species should be considered promising therapeutic agents in the treatment of upper respiratory tract and ulcer/inflammatory diseases.</p>","PeriodicalId":19942,"journal":{"name":"Pharmaceutical Biology","volume":"61 1","pages":"1484-1511"},"PeriodicalIF":3.8,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11001281/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138291573","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}
