Catalog Number: 3988
Chemical Name: N-[2,3-Dihydro-2-oxo-3-[(3Z)-phenyl[[4-(1-piperidinylmethyl)phenyl]amino]methylene]-1H-indol-5-yl]-ethanesulfonamide hydrochloride
Biological Activity
ATP-competitive inhibitor of Aurora B kinase (IC50 = 250 nM). Prevents chromosome alignment and segregation; also induces polyploidy and prevents histone H3-Ser10 phosphorylation. Overrides the spindle assembly checkpoint and induces mitotic exit in monastrol- and taxol-treated HeLa 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?
