RepSox is a cell permeable, selective inhibitor of the TGF-β type 1 receptor (TGFβRI) ALK5 (IC50 = 4, 18, and 23 nM for ALK5 autophosphorylation, TGF-β cellular assay, and ALK5 binding in HepG2 cells, respectively; Gellibert et al.) This inhibitor demonstrated less potent activity (IC50 > 16 μM) against 9 related kinases, including p38 MAPK and GSK3 (Gellibert et al.) This product is supplied as the hydrochloride salt of the molecule
