ALK-IN-31 (Compound Ld-10) is an orally active ALK inhibitor (IC50: 1135 nM). ALK-IN-31 exhibits excellent antiproliferative activity against lung cancer H2228 cells with an IC50 value of 1.35 µM. ALK-IN-31 induces apoptosis and arrests cell proliferation in the G0/G1 phase by affecting mitochondrial function. ALK-IN-31 exerts its anti-tumor effect by downregulating the expression of p-AKT and p-mTOR in the PI3K-AKT-mTOR signaling pathway downstream of ALK. ALK-IN-31 can be used in the study of non-small cell lung cancer (NSCLC)[1].
