  • Title: Cytotoxic xenia diterpenoids from the soft coral Xenia umbellata.
    Author: El-Gamal AA, Wang SK, Duh CY.
    Journal: J Nat Prod; 2006 Mar; 69(3):338-41. PubMed ID: 16562830.
    Abstract:
    Eleven new xenia diterpenoids, umbellacins A-G (1-7), 14,15-epoxy-xeniolide H (8), 3-acetyl-14,15-epoxy-xeniolide H (9), and umbellacins H and I (10, 11), were isolated from a methylene chloride-soluble fraction of the soft coral Xenia umbellata. The structures were elucidated by extensive spectroscopic analysis, and their cytotoxicity against selected cancer cells was measured in vitro.
