Litophynins I and J, Two New Biologically Active Diterpenoids from the Soft Coral Litophyton sp.

Abstract
Two new diterpenoids, litophynins I and J, which exhibit molluscicidal and repellent activities against the muricid gastropod Drupella fragum, have been isolated from the soft coral Litophyton sp. Their structures were fully characterized by extensive 2D-NMR studies.
