Abstract
Three new bromotyrosine alkaloids, pseudoceratinines A (1), B (2), and C (3), have been isolated from two specimens of the sponge Pseudocera tina verrucosa. In addition, the known alkaloids aplysamine-1 (4), apl ysamine-2 (5), purealin (6), and purealidins A (7) and B (8) were foun d in both specimens. The structures and absolute configurations of the new products were elucidated by spectral methods.
