Brominated Unsaturated Fatty Acids from Marine Sponge Collected in Papua New Guinea

New brominated fatty acids (3, 5—8, 10) and new sterol esters (14—16) have been isolated from an unidentified marine sponge collected in Papua New Guinea. Their structures were determined on the basis of their spectroscopic data. A major component of the marine sponge (1) was tested for activities against Arutemia salina and some fungi.
