Topical application of marine briarane-type diterpenes effectively inhibits 12-O-tetradecanoylphorbol-13-acetate-induced inflammation and dermatitis in murine skin

open access: yesJournal of Biomedical Science, 2011
Background Skin is the largest organ in the body, and is directly exposed to extrinsic assaults. As such, the skin plays a central role in host defense and the cutaneous immune system is able to elicit specific local inflammatory and systemic immune ...

Bioactive Compounds from the Gorgonian Briareum polyanthes. Correction of the Structures of Four Asbestinane-Type Diterpenes [PDF]

open access: yes, 2016
Our extended chemical investigation of the crude MeOH−CHCl3 extract of the gorgonian octocoral Briareum polyanthes from Puerto Rico has led to the isolation of three eunicellin-type diterpenoids, 1−3, along with five (4−8) diterpenoids of the asbestinane-

Studies of Australian Soft Corals. XLII. Structure Determination of New Briaran Derivatives From Briareum steckei (Coelenterata, Octocorallia, Gorgonacea) [PDF]

open access: yes, 1987
The structure and relative stereochemistry of four new metabolites from Briareum steckei has been deduced from 2D-n.m.r. experiments at high field, and confirmed by a single-crystal X-ray determination of a minor metabolite.
