Three new antibacterial alkaloids from a marine sponge Stelletta species.
From a marine sponge of the genus Stelletta we isolated three alkaloids, stellettazole B (3), stellettazole C (4), and stellettamide C (5), which were antibacterial against Escherichia coli. Their structures were determined on the basis of spectral and chemical methods.
