SD 208 is a 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.
SD 208 is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen Kinase Inhibitor Library. Find out more about compound libraries available from Tocris.
