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.

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.

AZ12601011 is an orally active, selective and potent TGFBR1 kinase inhibitor.AZ12601011 inhibits the release of inflammatory factors, interleukin (IL)-1β, IL-6 and tumor necrosis factor-α, and inhibits the growth of breast tumors.AZ12601011 directly binds to TGF-βR1 and blocks downstream Smad3 activation, which can be used to prevent renal fibrosis.

SB-525334 is a potent and selective inhibitor of the TGF-β1R and ALK5 (IC50: 14.3 nM).

LDN-212854 (BMP Inhibitor III), a novel BMP inhibitor, exhibits greater selectivity for BMP versus the TGF-β type I receptors; possesses differences towards ALK2(IC50=1.3 nM) versus ALK1/3 compared to other inhibitors.

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.

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

SM 16 is an ALK5/ALK4 kinase inhibitor with Ki values of 10 nM and 1.5 nM, respectively.

Vactosertib (EW-7197) is an orally bioavailable inhibitor of the serine/threonine kinase, transforming growth factor (TGF)-beta receptor type 1 (TGFBR1), also known as activin receptor-like kinase 5 (ALK5), with potential antineoplastic activity.

ALK4290 (AKST4290) is a potent, orally active CCR3 inhibitor (compound Example 2) with a Ki of 3.2 nM for hCCR3[1], suitable for research into neovascular age-related macular degeneration and Parkinsonism[2][3].

ALK4290 dihydrochloride (AKST4290 dihydrochlorid) serves as a potent and orally active inhibitor of CCR3, exhibiting a K i of 3.2 nM for hCCR3 [1]. It is primarily used in research related to neovascular age-related macular degeneration and Parkinsonism [2] [3].

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).

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].

K 02288 is a novel small molecule inhibitor of ALK1/2/3/6.

AZ 12799734 is an orally active, selective and potent dual inhibitor of TGFBR1 and ALK5 with inhibitory effects on BMP and TGFβ for the study of tumours.

LDN-193189 Tetrahydrochloride (DM-3189 Tetrahydrochloride) is a selective inhibitor of BMP type I receptors, inhibiting ALK2 and ALK3 (IC₅₀ = 5/30 nM), with weaker activity against ALK4, ALK5, and ALK7, and can be used for research into progressive osseous fibrodysplasia.

M4K2234 (Compound 26b) is a selective inhibitor of ALK2, displaying IC50 values of 5 nM for ALK2 and 2144 nM for ALK5. As a chemical probe for ALK1 and ALK2 kinases, it is used in mechanistic studies of BMP signaling and in cancer research where dysregulated ALK2 activity is implicated. Its high selectivity profile supports targeted investigations into ALK-mediated pathways.
