產品描述：
SB-431542 is a potent and selective inhibitor of the TGF-β1 receptor ALK5 (IC50 = 94 nM)1. It is a less potent antagonist of ALK4 (IC50 = 140 nM)2 and ALK7.3 It does not affect the BMP receptors ALK2, ALK3, ALK6, or a panel of other kinases tested.3 SB-431542 specifically blocks Smad signaling, reducing gene expression relevant to fibrosis and cancer.3 Through its effects on ALK/Smad signaling, SB-431542 suppresses renewal in embryonic and induced pluripotent stem cells and promotes their differentiation.4,51.Callahan, J.F., Burgess, J.L., Fornwald, J.A., et al.Identification of novel inhibitors of the transforming growth factor ?1 (TGF-?1) type 1 receptor (ALK5)Journal of Medicinal Chemistry45(5)999-1001(2002)
