The molecule is a 3beta-hydroxy steroid consisting of 23,24-dimethylcholest-16-ene substituted by hydroxy groups at positions 3, 5, 6 and 20 (the 3beta,5alpha,6beta,20S stereoisomer). Isolated from the soft coral Sarcophyton trocheliophorum, it exhibits cytotoxic activity against human cancer cells. It has a role as an antineoplastic agent and a coral metabolite. It is a 5alpha-hydroxy steroid, a 3beta-hydroxy steroid, a 6beta-hydroxy steroid and a 20-hydroxy steroid.
