Bioactive diterpenoids from Octocorallia, 2. Deoxyxeniolide B, a novel ichthyotoxic diterpenoid from the soft coral Xenia elongata

J Nat Prod. 1995 Jun;58(6):924-8. doi: 10.1021/np50120a017.


An ichthyotoxic diterpenoid, deoxyxeniolide B [1], was isolated from the soft coral Xenia elongata. It has also been shown that deoxyxeniolide B [1] is gradually oxidized in solution to give the oxidation products 2 and 3. The structures of these compounds were elucidated on the basis of spectral analysis.
