title: Haterumadysins A-D, sesquiterpenes from the Okinawan marine sponge Dysidea chlorea.
abstract: Haterumadysins A-D (1-4) and two known compounds, spirodysin (5) and dehydroherbadysinolide (6), were isolated from the sponge Dysidea chlorea. Their structures were successfully determined by detailed spectroscopic analysis. Compounds 1-5 all showed the ability to inhibit the division of fertilized sea urchin eggs.
