Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	ALK2 (Cell-free assay) 24 nM
In vitro	The kinase most highly inhibited by LDN-214117 is ALK2 (IC50, 24 nM), followed by TNIK, RIPK2, and ABL1. This compound demonstrates selective inhibition of ALK2 and ALK1 in preference to ALK3 kinase activity. It exhibits relatively selective inhibition of BMP6 versus BMP2 or BMP4. In a cell-based assay, this chemical exhibits a selective inhibition on BMP6 with IC50 of approximately 100 nM, and 164-fold selectivity for BMP6 versus TGF-β1.
Kinase Assay	ALK2 kinase assay
Kinase Assay	Purified recombinant ALK2 proteins, ATP, ATP[γ-32P], and dephosphorylated casein at final concentrations of 2.5 nM, 6 μM, 0.05 μCi/μL, and 0.5 mg/mL, respectively, are aliquoted in kinase buffer containing 0.2% BSA supplemented with 10 mM MnCl2 into 96-microwell plates, in combination with inhibitor compounds diluted at varying concentrations (0.01 nM to 100 μM). Positive control samples lacking this compound, and negative controls lacking recombinant kinase, are also measured. The mixture is reacted at RT for 45 min, quenched with a final concentration of 2% phosphoric acid. The reaction mixture is transferred to 96-well P81 phosphocellulose filter plates and bound for 5 min. The plates are washed 20 times with 150 μL of 1% phosphoric acid solution per well by vacuum manifold. Plates are dried at RT for 1 h, sealed, and assayed with Microscint 20 scintillation fluid using a Spectramax L luminometer. Data is normalized to positive controls at 100% enzyme activity, with negative controls being subtracted as background.
