Catalog Number: 5393
Chemical Name: 11-Cyclopentyl-2-[[2-ethoxy-4-[[4-(4-methyl-1-piperazinyl)-1-piperidinyl]carbonyl]phenyl]amino]-5,11-dihydro-5-methyl-6H-pyrimido[4,5-b][1,4]benzodiazepin-6-one
Biological Activity
Potent and selective ERK5 inhibitor; inhibits EGFR-induced ERK5 autophosphorylation (EC50 = 90 nM) and ERK5 enzymatic activity (IC50 = 162 nM). Exhibits at least 30-fold selectivity for ERK5 over LRRK2 in a cell based assay. Also selective for ERK5 over a panel of other kinases. Orally bioavailable.

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?
