title: New secosteroids from a gorgonian of the genus Muricella.
abstract: Calicoferols F-I (2-5), four new 9,10-secosteroids, have been isolated from a gorgonian of the genus Muricella collected from Jaeju Island, Korea. The structures of these compounds have been determined by combined spectroscopic methods. Calicoferols exhibited significant cytotoxicity and inhibitory activity against PLA2.
