Abstract

Four new aminosesquiterpenes, aminobisabolene (1~), aminobisabolenol (2 ~), isoaminobisabolenol-a (3~), and isoaminobisabolenol-b (4~), were isolated from an Okinawan marine sponge, Theonella sp. (Theonellidae) and their absolute configurations were determined. © 1987, The Pharmaceutical Society of Japan. All rights reserved.
