Survey of Briarane-Type Diterpenoids – Part IV

HETEROCYCLES, 2011
The structures, names, biological activities, and references of 137 briarane-type diterpenoids are summarized. All briaranes mentioned in this review article were obtained from various octocorals including the specimens belonging to the genus Briareum, Ellisella, Gorgonella, Junceella, Subergorgia, Renilla, and Pachyclavularia.

Briarane Diterpenes from Micronesian Gorgonians

HETEROCYCLES, 1996
Four new briaranes, nui-inoalides A-D, (6-9) are described. They were isolated from octocorals collected in Pohnpei and Ant atoll, Micronesia. The absolute stereochemistry of the known briarane juncin E (5) was determined. Nui-inoalide A (6) and the known gemmacolides A, B, and D (2-4) exhibit immunomodulatory activity.

Briarane Diterpenes from a Gorgonian Briareum Sp.

HETEROCYCLES, 2005
Eleven new briarane diterpenes have been isolated from a gorgonian Briareum sp., collected in the area of Bonotsu, Kagoshima Prefecture. Their structural elucidation and cytotoxicity tests toward Vero and MDCK cells were performed.

A concise synthetic route to the stereotetrad core of the briarane diterpenoids. [PDF]

Org Lett, 2015
A concise synthesis (under 10 steps) of the stereotetrad core of the briarane diterpenoids is reported. This approach harnesses the unique reactivity of salicylate ester derived 2,5-cyclohexadienones to quickly build complexity. In particular, a highly diastereoselective acetylide conjugate addition/β-ketoester alkylation sequence was used to set the ...

Survey of Briarane-related Diterpenoids — Part II

HETEROCYCLES, 2005
The structures, names, biological activity, and references of sixty-six new briarane-related diterpenoids are described in this mini-review. All briaranes are obtained from Gorgonacea (genus Briareum, Erythropodium, Ellisella, and Junceella) and Pennatulacea (genus Cavernularia and Pteroeides). Some of these natural products showed potential biological

Marine Invertebrate Natural Products for Anti‐Inflammatory and Chronic Diseases

Evidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
The marine environment represents a relatively available source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine invertebrates based compounds have biological activities and also interfere with the pathogenesis of diseases.
