The structures of compounds 1 and 2 were established by employing spectroscopic techniques (NMR, MS, UV, IR and polarimetry). This is the first report of metabolites of a sponge belonging to the genus Macandrewia.Isolation and structure elucidation of azoricasterol, a new sterol of the deepwater sponge Macandrewia azoricajournal_article10.1007/s00114-004-0552-615340692000224528000006
