New secosteroids from an undescribed gorgonian of the genus Muricella

Abstract

Three new 9,10-secosteroids, calicoferols C-E [2-4] have been isolated from an undescribed gorgonian of the genus Muricella, and their structures determined by a combination of spectroscopic methods. Calicoferol D [3] exhibited potent antiviral activity and brine-shrimp lethality.
