Bielschowskysin, a gorgonian-derived biologically active diterpene with an unprecedented carbon skeleton

Org Lett. 2004 May 13;6(10):1661-4. doi: 10.1021/ol049495d.

Abstract

Bielschowskysin is a naturally occurring diterpene isolated from the Caribbean gorgonian octocoral Pseudopterogorgia kallos. Its highly oxygenated hexacyclic structure is based on a previously undescribed tricyclo[9.3.0.0(2,10)]tetradecane ring system that was established through spectroscopic analysis and X-ray crystallographic analysis. Bielschowskysin was shown to exhibit antimalarial activity against Plasmodium falciparum as well as strong anticancer activity against two human cancer cell lines.
