Catalog Number: 2072
Alternate Names: NG 97
Chemical Name: (2R)-2-[[6-[(3-Amino-5-chlorophenyl)amino]-9-(1-methylethyl)-9H-purin-2-yl]amino]-3-methyl-1-butanol
Biological Activity
Cell-permeable cyclin-dependent kinase inhibitor. IC50 values are 0.033, 0.033, 0.028 and 0.020 μM for cdk1/cyclin B, cdk2/cyclin A, cdk2/cyclin E, and cdk5/p35 respectively. Inhibits ERK1 (IC50 = 12.0 μM) and ERK2 (IC50 = 3.1 μM) and is 3000-fold selective over a range of other protein kinases (IC50 > 100 μM). Arrests cell cycle at G2/M boundary (IC50 = 1.25 μM), and induces apoptosis at concentrations > 10 μM.

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?
