New 6,6-Spiroketal from the Alga-Derived Fungus Penicillium Lividum

Abstract

The new 6,6-spiroketal, sargassopenilline H (1), and known peneciraistin C (2) have been isolated from an EtOAc extract of the marine-derived fungus PenicilliumlividumKMM 4663. The structure of the new metabolite was determined by HR ESIMS and 1D and 2D NMR spectroscopy. Sargassopenilline H (1) in non-cytotoxic concentration inhibited colony formation of RPMI-7951 and MDA-MB-231 cell lines.
