New isomalabaricane derivatives from a new species of Jaspis sponge collected at the Vanuatu islands.
Six new cytotoxic isomalabaricane-type triterpenoids and nortriterpenoids with a 3alpha-acetoxy group were isolated, along with the known globostellatic acids B (1) and C (2), from the marine sponge Jaspis sp. collected at Vanuatu Island. The structures were determined by 2D NMR data and by comparison with spectral data of known related compounds.
