title: Isolation and structure elucidation of azoricasterol, a new sterol of the deepwater sponge Macandrewia azorica.
abstract: Chemical investigation of the deepwater sponge Macandrewia azorica, collected from the flanks of the Gettysburg and Ormonde Sea Mount, North Atlantic, from a depth of 600 m, has led to the isolation of a new sterol with an unusual side chain (1), along with S-methylergothioneine (2). 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.
