SD-208 was used to inhibit the activity of ALK5 kinase in bovine retinal vascular cells.2
Biological Activity
Potent, orally active ATP-competitive transforming growth factor- β receptor 1 (TGF- β RI) inhibitor (IC 50 = 49nM). Displays > 100-fold and > 17-fold selectivity over TGF- β RII and other common kinases respectively. Exhibits anti-inflammatory and antitumor activity.
Biochem/physiol Actions
SD-208 is an inhibitor of TGF β receptor 1 kinase that is reportedly effective against human malignant gliomas. It increases the lytic activity and tumor infiltration by polyclonal natural killer cells, CD8 T cells and macrophages.1
