Their therapeutic potential is increasingly bringing them to the forefront of biomedical research. Peptides from animal sources in particular are considered promising starting points for novel drug candidates. Until now, the focus has been primarily on exotic animals such as tropical frogs. However, it is becoming increasingly apparent that native amphibians could also be a previously overlooked but very rich source of bioactive peptides. Native species such as the grass frog, midwife toad and fire salamander produce skin secretions with antimicrobial, antiinflammatory, antitumour and/or wound-healing properties. Modified variants are even undergoing preclinical and clinical research. Nevertheless, some native species have not yet been analyzed for bioactive peptides in their skin secretions. Current and prospective studies will provide insights into this area and pave the way for new potential peptide therapeutics based on the biochemical resources of our native amphibians.</p>\u0000 </div>","PeriodicalId":9911,"journal":{"name":"Chemie in Unserer Zeit","volume":"60 2","pages":"88-93"},"PeriodicalIF":0.6,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
