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.
PF-0463481 is safe and well-tolerated and has the potential for the study of diabetic nephropathy. PF-0463481 is an effective and orally active dual CCR2CCR5 antagonist. It also has comparable human and rodent CCR2 potency (rat IC50=20.8 nM). PF-0463481
AZD2423 is a potent, selective, orally bioavailable, and non-competitive CCR2 chemokine receptor negative allosteric modulator and it has an IC50 of 1.2 nM for CCR2 Ca2+ flux [1][2][3].
