Studies on Formosan soft corals. II. Cytotoxic cembranolides from the soft coral Lobophytum michaelae

J Nat Prod. 1992 Oct;55(10):1430-5. doi: 10.1021/np50088a007.

Abstract

Bioactivity-guided fractionation of a CHCl3 extract of the soft coral Lobophytum michaelae afforded a new cytotoxic cembranolide, lobomichaolide (1), and a known cytotoxic cembranolide, crassolide (2). The structure of 1 was determined by spectral and X-ray crystallographic analysis.
