Catalog Number: 3994
Chemical Name: 9-Cyclopentyl-2-[[2-methoxy-4-[(1-methylpiperidin-4-yl)oxy]-phenyl]amino]-7-methyl-7,9-dihydro-8H-purin-8-one
Biological Activity
Potent and selective monopolar spindle 1 (Mps1) kinase inhibitor (IC50 = 35 nM). Displays selectivity over 46 other kinases including Cdk1 and aurora kinase B. Interferes with chromosome alignment and overrides spindle assembly checkpoint. Inhibits the recruitment of Mad1, Mad2 and centromere protein E (CENP-E) to kinetochores.

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?
