Abstract

Three new sesquiterpene quinols (1, 2, and 5) and two known ones (3 and 4) were isolated along with halistanol sulfate (6) from a marine sponge of the genus Aka collected from Yap Island, Federated States of Micronesia. Their structures were determined from spectral data, and the structure of siphonodictyal C (3) was revised. Sulfates 3 and 6 inhibit CDK4/cyclin D1 complexation, whereas 1 and 4 do not.
