General description
A cell-permeable pyridinyloxypyridine compound that acts as a potent and highly selective inhibitor against TGFβ RI/ALK5 (IC50 = 72 nM, [ATP] = 1 mM) by targeting both the ATP-binding site and the “selectivity pocket”, while exhibiting much reduced or little activity against a panel of 75 other kinases (IC50<1 µM). Shown to reduce TGFβ1-induced nuclear translocation of a GFP-Smad2 fusion reporter in MDA-MB-468 cells (IC50 = 22 nM) in vitro and exhibit excellent oral bioavailability (F = 75%, AUC = 4.95 µM.h) with low clearance (12 ml/min/kg) in rats in vivo.
