Dolabellane Diterpenoids from Soft Coral Clavularia viridis with Anti-Inflammatory Activities.

ABSTRACT: A chemical investigation of the EtOAc fraction from soft coral Clavularia viridis resulted in the isolation of 12 undescribed dolabellane-type diterpenoids, namely clavirolides W-Z (1-4), clavularols A-H (5-12), and three known analogs (13-15). Their structures were characterized by an extensive analysis of spectroscopic data, including X-ray diffraction and ECD calculations for the assignment of absolute configurations. The structures of 2 and 4-6 are feathered as peroxyl-substituted derivatives, while compounds 7-12 possess additional oxidative cyclization, including epoxide or furan that are rare in the dolabellane family. All these compounds were evaluated for activities on cytotoxic and anti-inflammatory models. Compound 10 exhibited most potential against NO production in the BV2 cel
