Catalog Number: 2727
Alternate Names: CP 597396
Chemical Name: [1-(Quinolin-5-yl)-5-cyclopropyl-1H-pyrazole-4-carbonyl]guanidine dihydrochloride
Biological Activity
Sodium-hydrogen exchanger isoform 1 (NHE1) inhibitor that displays selectivity over other NHE isoforms (Ki values are 14, 2200 and 220000 nM for human NHE1, human NHE2 and rat NHE3 respectively). Inhibits NHE1 dependent 22Na+ uptake in vitro (IC50 = 14 nM) and provides cardioprotection from myocardial ischemic injury in vivo (EC50 = 0.25 nM). Also inhibits MMP2/9 activity and invasion in breast cancer cells.

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?
