Synthesis of 5-membered ring-type compounds as potential cholecystokinin receptor ligands
Imidazolidine-2,4-diones and 1,5-diphenyl tetrainic acid derivatives were selected in order to evaluate some 5-membered heterocyclic ring compounds as potential templates for the synthesis of CCK receptor ligands. All the compounds were evaluated in vitro towards both CCK-B and CCK-A receptors.
