YM022
Based on 2 publication(s) in Google Scholar
YM022 is a highly potent, selective and orally active gastrin/cholecystokinin (CCK)-B receptor (CCK-BR) antagonist. YM022 shows the Ki values of 68 pM and 63 nM for CCK-B and CCK-A receptor, respectively. YM022 can inhibit gastrin-induced gastric acid secretion and histidine decarboxylase activation in vivo.

YM022 inhibits binding to canine pancreas CCK-A receptor in a dose-dependent manner, with an IC50 value for [3H]devazepide binding of 136 nM[1].
YM022 inhibits the binding of [125I]CCK-8 to canine cloned gastrin/CCK-B receptor in a dose-dependent manner, with an IC50 value for [125I]CCK-8 binding of 0.73 nM[1].
Selectivity [ratio of (IC50 for gastrin/CCK-B receptor)/(IC50for CCK-A receptor)] of YM022 is 186[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
YM022 (subcutaneous injection; 300 μmol/kg; single dose) lowers the oxyntic mucosal HDC activity and raises the serum gastrin concentration in a dose-dependent manner (measured 24 h after dosage). Maximum enzyme inhibition is achieved at a dose of 300 μmol/kg for YM022 and the inhibition of HDC lasts for 4 weeks. At sacrifice, drug residues can be seen at the injection site for as long as 4 (YM022) weeks after injection in rat[3].
YM022 is suspended in 2% Methocel for oral ingestion and in PEG300 for subcutaneous injection[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
