Popis: Synthesis and antifungal activity of cyclic octapeptide derivatives of burkholdines are described. To construct cyclic octapeptides, the combination of Fmoc-SPPS and cyclization with DIC/HOBt in the solution phase was employed. Synthesized peptides were evaluated for antifungal activity with MIC values against Saccharomyces cerevisiae, Aspergillus oryzae, and Candida viswanathii. As a result, the lipid side chain and the stereochemistry of each amino acid of Bk-1097 analogues significantly affected antifungal activity.
