Catalog Number: 1213
Chemical Name: 2-(2-Amino-3-methoxyphenyl)-4H-1-benzopyran-4-one
Biological Activity
Inhibitor of mitogen-activated protein kinase kinase (MKK / MEK). Acts by binding to the inactivated form of MEK, thereby preventing its phosphorylation by cRAF or MEK kinase (IC50 = 2-7 μM). Inhibits cell growth and proliferation in acute myelogenous leukemia (AML) cell lines; causes G1 arrest by blocking p53-dependent p21 induction. Enhances embryonic stem cell self-renewal. Also available as part of the MAPK Cascade Inhibitor Tocriset™ and MAPK Inhibitor Tocriset™.

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?
