Abstract
The structures, names, bioactivities and references of 138 briarane-type diterpenoids, including 87 new compounds, are summarized in this review. All the briarane-type compounds mentioned in this review article were obtained from gorgonian corals including the genus Briareum, Dichotella, Junceella and Verrucella. Some of these compounds showed potential bioactivities.
Highlights
This review describes the structures, names, bioactivities and references for all diterpenoid compounds in tabular form
In continuation of the search for new natural products from marine invertebrates collected off the waters of Taiwan at the intersection of the Kuroshio current and the South China Sea surface current, gorgonian B. excavatum, collected at Orchid Island off Taiwan, was examined for its complex and interesting chemical constituents
Approximately 600 briarane-type diterpenoids have been isolated from various marine organisms, soft corals belonging to the order
Summary
This review describes the structures, names, bioactivities and references for all diterpenoid compounds in tabular form. This study reviewed literature from 2011 to 2013 and describes 138 briarane-type diterpenoids (including 87 new compounds) that possess a bicycle [8.4.0] carbon skeleton, and most possess a γ-lactone moiety in their structure (Scheme 1). All briaranes mentioned in this article were isolated from octocorals belonging to the order Gorgonacea, including Briareum asbestinum, Briareum excavatum, Briareum spp., Dichotella fragilis, Dichotella gemmacea, Junceella fragilis, Junceella juncea and Verrucella umbraculum. This survey of briarane-type compounds is presented taxonomically according to genus and species.
