title: Phorbasin B and C: novel diterpenes from a southern Australian marine sponge, Phorbas species.
abstract: A southern Australian Phorbas sp. has yielded the novel diterpenes phorbasin B (2) and phorbasin C (3). Phorbasins B and C possess a hitherto unknown carbon skeleton, and their structures were assigned on the basis of detailed spectroscopic analyses.
