K. Yamada et al., BIOACTIVE TERPENOIDS FROM OCTOCORALLIA .3. A NEW EUNICELLIN-BASED DITERPENOID FROM THE SOFT CORAL CLADIELLA-SPHAEROIDES, Journal of natural products, 60(4), 1997, pp. 393-396
A new diterpenoid, cladiellaperoxide (2), has been isolated from the s
oft coral Cladiella sphaeroides, together with the known diterpenoid c
ladiellisin (1). Their structures were characterized by NMR studies an
d chemical conversion. The absolute configurations of 1 and 2 have bee
n elucidated by the modified Mosher method. Compound 2 showed lethalit
y toward brine shrimp.
