Abstract

Four new 12,8-Eudesmanolides (1-4) and one known compound 5 named 13-Hydroxy-3,7(11)-eudesmadien-12,8-olide, were isolated from a mangrove rhizosphere-derived fungus Eutypella sp. 1-15. Their structures with absolute stereochemistry were determined by the comprehensive spectroscopic data, experimental and calculated ECD analysis. Compound 1 exhibited potent anticancer activity against JEKO-1 and HepG2 with IC50 values of 8.4 and 28.5 μM, respectively. Additionally, compound 1 also showed moderate antimicrobial activity.
