Further membranolide diterpenes from the antarctic sponge dendrilla membranosa.
Chemical investigation of the Antarctic sponge Dendrilla membranosa collected from the vicinity of Palmer Station on Anvers Island, Antarctica, yielded three new diterpenes, membranolides B-D (2-4), as well as three previously reported sponge metabolites. Membranolides C and D (3, 4), bearing carboxylic acid functional groups, display Gram-negative antibiotic and antifungal activities.
