Abstract
Abstract Manzamines E ( 2 ) and F ( 3 ) have been isolated as cytotoxic constituents of a sponge of the genus Xestospongia and the structures elucidated by the application of 2D-NMR tecniques and spectroscoplc comparison with manzamine A (1). Manzamine F was shown to be identical with keramamine B ( 4 ), the structure of which should therefore be revised as 3 .
