alk2 in 2

ALK2-IN-2 is a potent and selective inhibitor of activin receptor-like kinase 2 (ALK2) with an IC50 of 9 nM, demonstrating 700-fold higher inhibition of ALK2 compared to ALK3.

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).

ALK2-IN-4 succinate is a potent and effective inhibitor of ALK2 (ActRI), providing significant promise for therapeutic uses [ActR-1].

M4K2281 is a potent and selective inhibitor of ALK2 with a half-maximal inhibitory concentration (IC50) of 2 nanomolar. In both biochemical and cellular assays, M4K2281 and M4K2308 demonstrate strong efficacy against ALK2. Moreover, M4K2281 exhibits a brain-to-plasma ratio that ranges from moderate to high.

Blu-782 (ALK2-IN-1) is a activin receptor-like kinase-2 (ALK2) inhibitor ( IC50 of <10 nM)

M4K2163 dihydrochloride, a potent and selective activin receptor-like kinase-2 (ALK2) inhibitor that is permeable to the blood-brain barrier (BBB), has an IC50 of 19 nM. This compound is useful in diffuse intrinsic pontine glioma (DIPG) research [1] [2].
