title: Biosynthetically diverse compounds from a saltwater culture of sponge-derived Aspergillus niger.
abstract: The new compound, asperic acid (1), and the known compounds hexylitaconic acid (2), malformin C (3), pyrophen (4), and asperazine (5) were isolated from the saltwater culture of Aspergillus niger derived from a Caribbean sponge, Hyrtios proteus. The structure elucidation of asperic acid is presented.
