Exploration of the pharmacophore of 3-alkyl-5-arylimidazolidinediones as new CB(1) cannabinoid receptor ligands and potential antagonists: synthesis, lipophilicity, affinity, and molecular modeling.


A set of 29 3-alkyl 5-arylimidazolidinediones (hydantoins) with affinity for the human cannabinoid CB(1) receptor was studied for their lipophilicity and conformational properties in order to delineate a pharmacophore. These molecules constitute a new template for cannabinoid receptor recognition, since (a) their structure differs from that of classical… (More)
