A 83-01 (ALK5 Inhibitor IV) is an inhibitor of the TGF-β type I receptors ALK5, ALK4, and ALK7 (IC50=12 45 7.5 nM). A 83-01 promotes the reprogramming of mouse fibroblasts into iPSCs. A 83-01 can be used in organoid cultures.

SB-431542 is an inhibitor of ALK5 TGF-β type I Receptor (IC50=94 nM) and is selective. SB 431542 also has inhibitory activity against ALK4 and ALK7 but not other proteins. SB 431542 can be used for induced differentiation of stem cells.

LDN193189 (LDN-193189) (DM 3189) is a selective BMP signaling inhibitor, inhibiting the transcriptional activity of ALK2 and ALK3 (IC50s: 0.8 0.8 5.3 16.7 nM for ALK1 2 3 6).

SB505124 is a selective inhibitor of TGFβR for ALK4, ALK5.

A 83-01 sodium salt is a potent inhibitor of TGF-β type I receptor ALK5 kinase, ALK4 and ALK7, with IC 50 s of 12 nM, 45 nM and 7.5 nM against the ALK5, ALK4 and ALK7 induced transcription, respectively [1].

LDN193189 Tetrahydrochloride is a selective inhibitor of BMPI-type receptors and inhibits ALK2 (IC50: 5 nM) and ALK3 (IC50: 30 nM), with weak effects on ALK4, ALK5 and ALK7 (IC50 ≥ 500 nM).

SB-505124 hydrochloride (SB505124 hydrochloride) is an orally available, selective and potent inhibitor of TGF-β type I receptors (ALK4, ALK5, ALK7) with IC50 values of 129 nM and 47 nM for ALK4 and ALK5, respectively. SB-505124 hydrochloride inhibits IL-6 production by synovial explants and reduces Th17 differentiation in mice by decreasing Il17a and Rorc gene expression and IL-17 protein production.SB-505124 hydrochloride is used in the study of colorectal cancer.
