Manoalide derivatives from a sponge, Luffariella sp.

摘要

A new derivative of manoalide, 24-n-propyl-O-manoalide (1) together with manoalide (4) and four known derivatives (2, 3, 5, 6) were isolated from the methanolic extract of a sponge. Their structures were elucidated on the basis of spectroscopic method. All the compounds showed significant cytotoxicity against HCT-116 cell line by MTS assay. Secomanoalide indicated antifungal activity on fungal lines Candida glabrata,Candida krusei and Candida albicans by invitro antibiotic assay.
