Cat.No.S2934

Ensartinib dihydrochloride is a potent new-generation ALK inhibitor with high activity against a broad range of known crizotinib-resistant ALK mutations and CNS metastases. It potently inhibits both wild-type ALK and ALK variants (F1174, C1156Y, L1196M, S1206R, T1151, and G1202R mutants) with in vitro IC50s of <4 nM.

In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	5.000mg/ml (7.88mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

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.

Targets/IC₅₀/Ki	TPM3-TRKA (Cell-free assay) <1 nM TRKC (Cell-free assay) <1 nM GOPC-ROS1 (Cell-free assay) <1 nM ALK (Cell-free assay) <4 nM ALK variants (Cell-free assay) <4 nM
In vitro	Ensartinib potently inhibits both wild-type ALK and all evaluated ALK variants (F1174, C1156Y, L1196M, S1206R, T1151, and G1202R mutants) with in vitro IC50s of <4 nM. Besides ALK, ensartinib also potently inhibits TPM3-TRKA, TRKC and GOPC-ROS1 with an IC50 of <1 nM, and inhibits EphA2, EphA1, EphB1 and c-MET with an IC50 of 1-10 nM.
