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.

Technical Data

Soluble to 20 mM in DMSO with gentle warming
>98 %
Store at RT
