ALK3 Inhibitor

Dorsomorphin (BML-275) is a selective and ATP-competitive AMPK inhibitor (K_i=109 nM in the absence of AMP). Dorsomorphin (BML-275) selectively inhibits BMP type I receptors ALK2, ALK3, and ALK6. Dorsomorphin can reverse autophagy activation and anti-inflammatory effect of Urolithin A (HY-100599).

LDN193189 (DM-3189) is a potent selective BMP type I receptor (BMP I) inhibitor. LDN193189 efficiently inhibits transcriptional activity of the BMP type I receptors ALK2 and ALK3 with IC₅₀ values of 5 nM and 30 nM, respectively. LDN193189 can be used for the research of bone morphogenetic protein signalling, such as fibrodysplasia ossificans progressiva.

Dorsomorphin (Compound C) dihydrochloride is a potent, selective and ATP-competitive AMPK inhibitor, with a K_i of 109 nM. Dorsomorphin dihydrochloride inhibits BMP pathway by targeting the type I receptors ALK2, ALK3, and ALK6. Dorsomorphin dihydrochloride can reverse autophagy activation and anti-inflammatory effect of Urolithin A (HY-100599).

LDN193189 (DM-3189) Tetrahydrochloride is a potent selective BMP type I receptor (BMP I) inhibitor. LDN193189 efficiently inhibits transcriptional activity of the BMP type I receptors ALK2 and ALK3 with IC₅₀ values of 5 nM and 30 nM, respectively. LDN193189 can be used for the research of bone morphogenetic protein signalling, such as fibrodysplasia ossificans progressiva.

LDN-214117 is an orally active ALK2 inhibitor with well-tolerated and good brain penetration. LDN-214117 has a high selectivity and low cytotoxicity for ALK2 with an IC₅₀ value of 24 nM. LDN-214117 also is a specific bone morphogenetic proteins (BMPs) signaling inhibitor and has relatively selective inhibition for BMP6 with an IC₅₀ value of 100 nM. LDN-214117 can be used for the research of fibrodysplasia ossificans progressiva (FOP), diffuse intrinsic pontine glioma (DIPG) .

HM-279 is a potent and orally active ALK5 inhibitor with an IC₅₀ of 4.7 nM. HM-279 shows cross-reactivity with ALK7 (IC₅₀ = 6.8 nM), but HM-279 has fair to good selectivity against other TGF-β receptor family kinases, with 4.5-693-fold selectivity. HM-279 demonstrates antitumor activity in vivo through CD8⁺ T cell immunity. HM-279 can be used for the research of colon cancer.

LDN-212854 is a bone morphogenetic protein (BMP) inhibitor that potently inhibits ALK2 (IC₅₀: 1.3 nM). LDN-212854 also inhibits ALK1 (IC₅₀: 2.40 nM). LDN-212854 can be used in the research of fibrodysplasia ossificans progressive and cancers, such as hepatocellular carcinoma (HCC).

ML347 (LDN193719) is a highly selective ALK1/ALK2 inhibitor. ML347 has IC₅₀ values of 46 and 32 nM against ALK1 and ALK2, respectively, >300-fold selective over ALK3. ML347 block the phosphorylation of Smad1/5 by TGF-β1.

AZ12799734 is a selective, orally active TGFBR1 kinase inhibitor with an IC₅₀ of 47 nM. AZ12799734 is also a pan BMP and TGFβ inhibitor.

CDD-2789 is a potent and selective ALK2 inhibitor with an IC₅₀ 0.54 μM and a K_d of 2.1 nM, respectively. CDD-2789 exhibits >120-fold selectivity over ALK3/5/6. CDD-2789 reduces activin A- and BMP2-induced SMAD1/5 phosphorylation in fibroblasts. CDD-2789 can be used for ALK2-related cancer research.
