Abstract

Two new substituted pyrrolecarboxylic acids, makaluvic acids A (5) and B (6), were isolated from the Sponge Zyzzya fuliginosus, which was collected in Chuuk Atoll, Federated States of Micronesia. The known Alkaloids 3,7-dimethylisoguanine (1) and makaluvamines A (2), E (3), and K (4) were also isolated.
