Abstract:
A novel series of cannabinoid ligands with a structurally unique tri-aryl core has been designed, synthesized and assayed. Receptor binding assays show that these compounds possess CB2 receptor sub-type selectivity with binding affinities ranging from 1.07 (+/-0.05) for 7 to 4.77 (+/-0.57) nM for 6. The selectivity of the compounds was enhanced 9-600-fold for the CB2 receptor over the CB1 receptor. The results of our present study identify a novel, highly selective cannabinoid scaffold with a non-classical core.
