General description

A cell-permeable naphthyridinyl pyrazolo compound that acts as a potent, selective, reversible, and ATP-competitive inhibitor of TGF-β type I receptor (ALK5; IC50 = 23 nM, 4 nM and 18 nM for ALK5 binding, ALK5 auto-phosphorylation and TGF-β cellular assay in HepG2 cells, respectively). Minimally affects a panel of 9 closely related kinases including p38 MAPK at IC50 >16 µM. Also available as a 50 mM solution in DMSO (Cat. No. 508158).
