Massadine, a Novel Geranylgeranyltransferase Type I Inhibitor from the Marine Sponge Stylissa aff. m assa

Abstract

Massadine, a highly oxygenated alkaloid, was isolated from the marine sponge Stylissa aff. massa as an inhibitor of geranylgeranyltransferase type I (GGTase I). The structure of massadine has been deduced from spectral data. Massidine inhibited GGTase I from Candida albicans with an IC(50) value of 3.9 microM. [structure: see text]
