ATM-IN-2
ATM-IN-2 is a selective and orally active ATM inhibitor with an IC50 of 4 nM. ATM-IN-2 exhibits excellent kinase selectivity (>700-fold over PIKK family members). ATM-IN-2 exerts its anti-tumor effect by inhibiting ATM phosphorylation and the downstream signaling pathways (p53, H2AX), and promotes cell apoptosis. ATM-IN-2 can be used for the study of chemosensitizer candidate such as colon cancer.

Biological Activity
|
ATM 4 nM (IC50) |
ATM-IN-2 (Compound 25a) (0-10000 nM, 6-7 days) shows good inhibitory activity against HEL116 and SW620 cells, with IC50 values of 58.2 and 66.6 nM, and effectively inhibits the ability of cell clonal formation[1].
ATM-IN-2 (1-4 μM, 2 days) enhances the therapeutic efficacy of Irinotecan (HY-16562) by exacerbating G2/M phase arrest, and promoting apoptosis, and achieving synergistic antiproliferative effects in HCT116 cells[1].
ATM-IN-2 (0.25-2 μM, 4 h) significantly inhibits ATM signaling activation in HCT116 and SW620 cells[1].
