Diurnal Activity of Hermatypic Gorgonians

Nature, 1967
THE natural food of gorgonians, or any other soft corals, inhabiting coral reefs is unknown, but net photosynthesis to respiration ratios from 2 to 5 have been reported for isolated colonies of five species of Caribbean reef gorgonians in laboratory experiments1,2.

New Cembranolides from the Gorgonian Eunicea succinea

Journal of Natural Products, 1998
A new chemical study of the Caribbean gorgonian Eunicea succinea collected in Puerto Rico afforded seven new cembranolides (1-5, 7, and 8). Excepting 1, the new compounds described here possess an unusual unsaturation at either position C-1, C-6, or C-8, and all but 8 possess the C-12R, C-13S stereochemistry usually ascribed to cembranolides from E ...

New Farnesylhydroquinone Glycosides from the Gorgonian Euplexaura anastomosans

Natural Product Letters, 2001
Euplexides F (3) and G (4), novel farnesylhydroquinone glycosides, have been isolated as minor constituents of the gorgonian Euplexaura anastomosans. The structures of these compounds have been determined by combined spectroscopic methods. These compounds exhibited moderate cytotoxicity and inhibitory activity against PLA2.

Bacterial Communities of the Gorgonian Octocoral Pseudopterogorgia elisabethae

Microbial Ecology, 2013
Pseudopterogorgia elisabethae is a common inhabitant of Caribbean reefs and is a well-known source of diterpenes with diverse biological activities. Notably, this octocoral is the sole source of the pseudopterosin family of anti-inflammatory diterpenes and is harvested to supply commercial demand for these metabolites.

Diterpenoids from the gorgonian Solenopodium stechei

The Journal of Organic Chemistry, 1992
Twenty-five new diterpenoids with representatives from three skeletal classes, briareins, eunicellins and cembranes, have been isolated from a Pacific gorgonian, Solenopodium stechei. The structural diversity of the diterpenoids isolated indicates significant biosynthetic versatility for this gorgonian.
