the human CB(1) cannabinoid receptor has been evaluated. These compounds are derived from the previously described cannabinoid ligands 5,5'-diphenylimidazolidine-2,4-dione (hydantoins). The replacement of the oxygen by a sulfur leads to an increase of the affinity while the function-i.e., inverse agonism-determined by [(35)S]GTPgammaS experiments remains unaffected.
