Catalog Number: 4191
Chemical Name: 8-[[(4R)-3,4-Dihydro-5-methyl-2H-1-benzopyran-4-yl]amino]-N-(2-hydroxyethyl)-N,2-dimethyl-imidazo[1,2-a]pyridine-6-carboxamide
Biological Activity
H+,K+-ATPase inhibitor (pIC50 = 6 in human recombinant ion-leaky assays); more potent in acidic conditions. Highly selective for H+,K+-ATPase in vitro; displays no activity at Na+,K+-ATPase. Also displays selectivity for H+,K+-ATPase over a range of 50 receptors and ion channels (IC50 > 10 μM). Inhibits gastric acid secretion in rat and dog models.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
