Additional Dolabellane Diterpenes from the Caribbean Gorgonian Octocoral Eunicea laciniata

Abstract

The Caribbean gorgonian octocoral Eunicea laciniata from the coasts of Palomino Island, Puerto Rico, has yielded four known and five new diterpenes based on the dolabellane ring system. The structures of the novel compounds 3-7 were established by interpretation of their spectral data. Some of these new compounds showed weak cytotoxicity against HeLa cells.
