Oxygenated cembranoids of the decaryiol type from the Indonesian soft coral Lobophytum sp. [PDF]

Tetrahedron, 2009
Three novel cembrane diterpenoids, decaryiols B-D (5-7), characterized by a bicyclic skeleton of the decaryiol-type, have been isolated from the Indonesian soft coral Lobophytum sp., along with three known cembranoids.

New cembranoids from plexaura

Tetrahedron, 1989
Abstract Three new cembranoids, dihydroplexaurolone (2) and two dehydroplexaurolones (3) and (4), have been isolated from the gorgonlan Plexaura A. The structure of 2 was established by X-ray crystallographic studies. Crystals of 2 belong to space group P21, with a = 10.711 (2) A, b = 10.976 (3) A, c = 17.148 (4) A, β = 99.99 (2)°, and Z = 4.

Characterization of Cembranoid Interaction with the Nicotinic Acetylcholine Receptor

The Journal of Pharmacology and Experimental Therapeutics, 1998
The class of diterpenoids with a 14-carbon cembrane ring, the cembranoids, includes both competitive and noncompetitive inhibitors of the nicotinic acetylcholine receptor (AChR). All 20 coelenterate-derived cembranoids studied in this report inhibited [piperidyl-3,4-3H]-phencyclidine ([3H]-PCP) binding to its high-affinity site on the electric organ ...

Cembranoids from the Octocoral Sarcophyton ehrenbergi

Journal of Natural Products, 2010
Chemical investigation of the octocoral Sarcophyton ehrenbergi led to the isolation of six new cembranoids, (+)-12-carboxy-11Z-sarcophytoxide (1), (+)-12-methoxycarbonyl-11Z-sarcophine (3), ehrenberoxides A-C (4-6), and lobophynin C (2), along with two known compounds, (+)-sarcophytoxide (7) and (+)-sarcophine (8).

Cyclized Cembranoids of Natural Occurrence

1992
The structure of eunicillin (89), a carbobicyclic diterpenoid isolated from the Mediterranean gorgonian Eunicella stricta, was reported in 1968 (1). At that time chlorine-containing diterpenoids had been discovered in the gorgonian Briareum asbestinum (2, 3), but it was not until 1977 that the structure of the first briaran, briarein A (211), was ...
