Abstract
Polyhydroxylated steroids and other metabolites were isolated from the soft coral Nephthea chabroli collected in South China Sea. The structures of two new compounds were determined to be 24-methylcholesta-9(11), 24(28)-diene-3beta,12alpha,19-triol and 4alpha-methyl-3beta,14beta-dihydroxy-5alpha-ergost-24(28)-en-23-one on the basis of spectroscopic analysis. Cytotoxic activities of the polyhydroxylated sterols were evaluated on prostate carcinoma LNCaP cell line.
