Potent and selective inhibitor of TGF-β type I receptor (ALK5). Inhibits Smad-2 phosphorylation (IC50 = 5.3 nM). Exhibits selectivity over a panel of 27 serine/ threonine and tyrosine kinases including P38α. Attenuates TGFβ/Smad signaling, cell migration, invasion, lung metastasis and increases survival of mice in 4TI in vivo models. Suppresses renal fibrosis in obstructive nephropathy in vivo models.
