Cladieunicellin H, a new hemiketal eunicellin-based diterpenoid from the octocoral Cladiella sp.

摘要

A new hemiketal eunicellin-based diterpenoid, cladieunicellin H (1), was isolated from an Indonesian octocoral identified as Cladiella sp. The structure of 1 was determined by spectroscopic methods. This compound was found to display moderate inhibitory effects on the generation of superoxide anion and the release of elastase by human neutrophils.
