The Heterocyclic Natural Products of Gorgonian Corals of Genus Briareum Exclusive of Briarane-Type Diterpenoids

Abstract

An overview on the heterocyclic natural products of gorgonian octocorals of genus Briareum is presented.Based on previous studies, most of the heterocyclic natural products from Briareum are diterpenoid metabolites, including eunicellin, asbestinane, cembrane, and briarane-type derivatives.The structures, names, biological activities, and references of these natural products exclusive of briaranes are described in this review.
