CCK-B Receptor Antagonist 2 is a potent and orally active antagonist of Gastrin CCK-B (IC50: 0.43 nM). It also inhibits gastrin CCK-A activity (IC50: 1.82 μM).
Proglumide hemicalcium is a antagonist of nonpeptide and orally active cholecystokinin (CCK)-A B receptors, has antiepileptic and antioxidant activities.
Devazepide is a competitive and orally active nonpeptide antagonist of cholecystokinin (CCK) receptor (IC50s: 81 pM, 45 pM, and 245 nM for rat pancreatic, bovine gallbladder and guinea pig brain CCK receptors, respectively).
Dexloxiglumide, an active enantiomer of Loxiglumide, inhibits smooth muscle cell contractions induced by cholecystokinin-octapeptide (CCK-8). It is a selective antagonist of cholecystokinin type A (CCKA) receptors.
YM022 is a highly effective and selective gastrin cholecystokinin (CCK)-B receptor antagonist. YM022 can inhibit gastrin-induced gastric acid secretion and histidine decarboxylase activation in vivo. YM022 shows the Ki values of 68 pM and 63 nM for CCK-B and CCK-A receptor, respectively.
