A cembranoid from tobacco prevents the expression of nicotine-induced withdrawal behavior in planarian worms [PDF]

European Journal of Pharmacology, 2009
Using an adaptation of published behavioral protocols, we determined that acute exposure to the cholinergic compounds nicotine and carbamylcholine decreased planarian motility in a concentration-dependent manner. A tobacco cembranoid (1S,2E,4R,6R,7E,11E)-

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.
