M4K-2009 (Compound 6a) potently inhibits wild-type recombinant ALK2 with an IC50 value of 13 nM, and maintains comparable inhibitory activity against ALK2G328V, ALK2R206H and ALK2R258G[1].
M4K-2009 inhibits wild-type ALK2 in HEK-293 cells with an IC50 of 45 nM, and exhibits potent activity against ALK2G328V, ALK2G356D, ALK2Q207D and ALK2R206H in the same cell line[1].
M4K-2009 (1 μM) exhibits high selectivity at the kinome-wide level. At a concentration of 1 μM, only 2.1% of the 374 tested kinases are inhibited by over 50%, and its potent off-target activity is restricted solely to DDR1 (IC50 = 41 nM) and TNIK (IC50 = 96 nM)[1].
M4K-2009 inhibits the viability of DIPG-XXI cells with a GI50 of 52 nM; it also inhibits the viability of HSJD-DIPG-007 cells with a GI50 of 130 nM[1].
M4K-2009 moderately inhibits

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.96 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.96 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
