Catalog Number: 3269
Chemical Name: 2-(5-Chloro-2-fluorophenyl)-4-[(4-pyridyl)amino]pteridine
Biological Activity
Potent, orally active ATP-competitive transforming growth factor-β receptor 1 (TGF-βRI) inhibitor (IC50 = 49 nM). Displays > 100-fold and > 17-fold selectivity over TGF-βRII and other common kinases respectively. Exhibits anti-inflammatory and antitumor activity. Also promotes an antiglioma immune response. Ameliorates germinal matrix hemorrhage-induced neurological deficits in neonatal rats.

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?
