G. Pentassuglia et al., SYNTHESIS OF 5-MEMBERED RING-TYPE COMPOUNDS AS POTENTIAL CHOLECYSTOKININ RECEPTOR LIGANDS, Il Farmaco, 52(10), 1997, pp. 573-581
Imidazolidine-2,4-diones and 1,5-diphenyl tetramic acid derivatives we
re selected in order to evaluate some 5-membered heterocyclic ring com
pounds as potential templates for the synthesis of CCK receptor ligand
s. All the compounds were evaluated in vitro towards both CCK-B and CC
K-A receptors.
