Newly developed cannabinoids may hold the promise of the development of useful and safe drugs. This study aimed to investigate the behavioral effects of the novel 1',1'-dithiolane delta8-HC analogue AMG-3, a cannabinomimetic molecule with high affinity for CB1/CB2 receptors. This analog was chosen for its binding affinity to these receptors, which is higher(More)
The synthetic cannabinoid (-)-2-(6a,7,10,10a-tetrahydro-6,6,9-trimethyl-1-hydroxy-6H-dibenzo[b,d]+ ++pyranyl)-2-hexyl-1,3-dithiolane (AMG-3) is a cannabimimetic molecular probe with one of the highest binding affinities reported to date. Therefore, due to its potential pharmacological importance, its structure was sought to be elucidated and its(More)
Accumulated evidence indicates that within the cannabinoid structure the aliphatic side chain plays a pivotal role in determining cannabimimetic activity. We describe the synthesis and affinities for the CB1 and CB2 receptors of a series of novel delta 8-THC analogues in which the side-chain pharmacophores are conformationally more defined than in the(More)
The presence of halogens within the classical cannabinoid structure leads to large variations in the compounds' potencies and affinities for the CB1 receptors. To explore the structure activity relationships within this class of analogs we have used a series of halogen-substituted (−)-Δ8-tetrahydrocannabinol analogs and compared their affinities for the CB1(More)
A general and convenient synthesis of beta-ketols and alpha,beta-alkenones has been achieved by a Knoevenagel condensation of a beta-ketoacid with an aldehyde in aqueous medium. Saponification of a beta-ketoester by an aqueous KOH 10% solution gives the potassium salt of the beta-ketoacid, which is condensed in situ with an aldehyde at pH 7.8-8.0, at 60(More)
We have studied the thermotropic properties of a wide variety of cannabinoids in DPPC bilayers. The molecules under study were divided into four classes: (a) classical cannabinoids possessing a phenolic hydroxyl group; (b) delta9-THC metabolites with an additional hydroxyl group on the C ring; (c) non-classical cannabinoids, and (d) cannabinoids with a(More)
Earlier work from our laboratories has provided evidence for the existence of a subsite within the CB1 and CB2 cannabinoid receptor binding domain corresponding to substituents at the benzylic side chain position of classical cannabinoids. The existence and stereochemical features of this subsite have now been probed through the synthesis of a novel series(More)
A set of 30 novel Delta8-tetrahydrocannabinol and cannabidiol analogues were subjected to three-dimensional quantitative structure-activity relationship studies using the comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) approaches. Using a combination of molecular modeling techniques and NMR(More)
