Chemical Name: 2-(3-(6-Methylpyridine-2-yl)-1H-pyrazol-4-yl)-1,5-naphthyridine
Biological ActivityPotent and selective inhibitor of the TGF-β type I receptor/ALK5 (IC50 values are 4 and 23 nM for TGF-β type I receptor autophosphorylation and binding respectively). Selective for TGF-β type I receptor over a range of kinases, including p38 MAPK, JNK1 and GSK3 (IC50 > 16 μM). Enhances the efficiency of cellular reprogramming; replaces Sox2 by inducing Nanog expression.
