Briarane diterpenoids isolated from gorgonian corals between 2011 and 2013

Area of Science:

• Marine natural products chemistry
• Organic chemistry
• Pharmacology

Background:

• Gorgonian corals are a rich source of structurally diverse secondary metabolites.
• Briarane-type diterpenoids represent a significant class of compounds isolated from these marine organisms.
• Previous research has identified various briarane derivatives with notable biological activities.

Purpose of the Study:

• To compile and review the known structures, names, bioactivities, and references of briarane-type diterpenoids.
• To highlight newly discovered briarane compounds and their origins.
• To provide a comprehensive resource for researchers in marine natural products and medicinal chemistry.

Main Methods:

• Literature review and data compilation from scientific databases and publications.
• Structure elucidation of briarane-type diterpenoids isolated from gorgonian corals.
• Bioactivity screening and assessment of reported biological effects.

Main Results:

• Summary of 138 briarane-type diterpenoids, with 87 being newly reported compounds.
• Identification of the source organisms, primarily gorgonian corals from genera such as Briareum, Dichotella, Junceella, and Verrucella.
• Documentation of the chemical structures, nomenclature, and reported bioactivities for each compound.

Conclusions:

• This review consolidates the chemical diversity of briarane diterpenoids from gorgonian corals.
• The significant number of new compounds underscores the potential for further discoveries in this chemical class.
• The reported bioactivities suggest that briarane diterpenoids are promising candidates for drug development.
