Further investigation of the Okinawan sponge Haliclona sp. resulted in the isolation of manzamines B-F (182-186), which show cytotoxic activity (152-154). The structures of manzamines B (182) and C (183) were based on X-ray analysis. Manzamine F (186) was found to be identical with keramamine B, the structure of which with a 1,2,3-triazacyclohexane moiety (181) was revised to structure 186 containing a hexahydro-5(2//)-azocinone ring. Total synthesis of manzamine C (183) was achieved by the...
