Catalog Number: 2542
Chemical Name: N-(2,4-Difluorophenyl)-N'-[4-[(6,7-dimethoxy-4-quinolinyl)oxy]-2-fluorophenyl]urea
Biological Activity
Potent, selective inhibitor of VEGFR-2 tyrosine kinase (IC50 = 0.9 nM). Displays some inhibitory activity towards c-Kit, PDGFRα and FGFR-2 (IC50 values range from 40 to 170 nM) but is highly selective over other receptor tyrosine kinases (IC50 > 10000 nM for FGFR-2, EGFR and HGFR). Inhibits VEGF-stimulated proliferation of human umbilical vein endothelial cells (HUVEC) and inhibits tumor growth in vivo; antiangiogenic.

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?
