The novel pyrrole-imidazole alkaloids cyclooroidin (7) and taurodispacamide A (8) have been isolated from the Mediterranean sponge Agelas oroides, and their structures established from spectroscopic data. Although both these alkaloids may be conceived as derivatives of the C 11 N 5 skeleton of the k
