YM022 is a highly effective and selective gastrin cholecystokinin (CCK)-B receptor antagonist. YM022 can inhibit gastrin-induced gastric acid secretion and histidinedecarboxylase activation in vivo. YM022 shows the Ki values of 68 pM and 63 nM for CCK-B and CCK-A receptor, respectively.
MK785 is part of the association between inhibition of aortic histamine formation, aortic albumin permeability, and atherosclerosis. Aortic histamine synthesis was inhibited by partial inhibition of aortic histidinedecarboxylase (HD) by application of MK
