ensartinib hydrochloride

Ensartinib hydrochloride (X-396 dihydrochloride) is a potent new-generation ALK inhibitor with high activity against CNS metastases and a broad range of known crizotinib-resistant ALK mutations. It potently inhibits both wild-type ALK and ALK variants (C1156Y, F1174, G1202R, L1196M, S1206R, and T1151 mutants) with in vitro IC50s of <4 nM.

Ensartinib (X-396) is a potent dual ALK MET inhibitor with IC50 values of <0.4 nM for ALK and 0.74 nM for MET.

X-376 (Ensartinib) is an orally available small molecule inhibitor of the receptor tyrosine kinase anaplastic lymphoma kinase (ALK) with potential antineoplastic activity. Upon oral administration, X-396 binds to and inhibits ALK kinase, ALK fusion proteins, and ALK point mutation variants. Inhibition of ALK leads to the disruption of ALK-mediated signaling and eventually inhibits tumor cell growth in ALK-expressing tumor cells. ALK belongs to the insulin receptor superfamily and plays an important role in nervous system development.
