M. Mcnally et Rj. Capon, Phorbasin B and C: Novel diterpenes from a southern Australian marine sponge, Phorbas species, J NAT PROD, 64(5), 2001, pp. 645-647
A southern Australian Phorbas sp. has yielded the novel diterpenes phorbasi
n 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 detaile
d spectroscopic analyses.
