title: Phorbasins G--I: three new diterpenoids from the sponge Phorbas gukulensis.
abstract: Phorbasins G--I (1--3) were isolated from the sponge Phorbas gukulensis collected from Gagu-Do, Korea. The complete structure of the compounds was determined by NMR and MS spectroscopy, along with chemical reaction. Phorbasin G (1) was found to be a diterpene possessing a taurine residue.
