12-Acetoxypseudopterolide: a new Diterpene from Pseudopterogorgia elisabethae

Chemical studies on the non polar fraction of the methanolic extract of Pseudopterogorgia elisabethae Bayer collected from the Florida Keys has yielded 12-acetoxypseudopterolide (1), a new diterpene of the pseudopterane series. The structure was established through spectroscopic analysis. Compound (1) was shown to exhibit modest anti-cancer activity against a human prostate cancer cell line (LnCap).
