ATM-IN-13
ATM-IN-13 (A36) is an orally active, selective ATM kinase inhibitor with a human IC50 of 0.3 nM. ATM-IN-13 blocks the ATM-mediated DNA double-strand break repair signaling pathway, reduces the phosphorylation levels of ATM and p53, and inhibits ATM-dependent DNA damage response. ATM-IN-13 can be used in the research of colorectal cancer.

ATM-IN-13 (A36) potently inhibits purified ATM kinase with an IC50 of 0.3 nM[1].
ATM-IN-13 (A36) exhibits high kinase selectivity, with >3333-fold selectivity over ATR, mTOR, and PI3Kα, and 493-fold selectivity over DNA-PK relative to its ATM IC50 of 0.3 nM[1].
ATM-IN-13 (A36) inhibits proliferation of 2 Gy-irradiated HCT116 colorectal cancer cells with an IC50 of 1.7 nM[1].
ATM-IN-13 (A36) (20-40 nM; 6 days) potently enhances the cytotoxicity of irinotecan in HCT116 and SW620 colorectal cancer cells, with greater synergistic effects in SW620 cells[1].
ATM-IN-13 (A36) (10-20 nM) enhances the ability of irinotecan to suppress colony formation in colorectal cancer cells[1].
ATM-IN-13 (A36) (2 μM) inhibits the irinotecan-activated ATM signaling pathway in HCT116 colorectal cancer cells, reducing levels of γ-H2AX, phosphorylated ATM, and phosphorylated p53[1].
ATM-IN-13 (A36) (0.5-2 μM) concentration-dependently reduces irinotecan-induced γ-H2AX levels in HCT116 colorectal cancer cells, confirming inhibition of ATM-mediated DNA damage signaling[1].
ATM-IN-13 (A36) (0.008-1 μM; 48 h) alone does not alter cell cycle distribution in HCT116 or SW620 colorectal cancer cells, but enhances irinotecan-induced G2/M phase arrest in a concentration-dependent manner[1].
ATM-IN-13 (A36) (0.25-0.5 μM; 48 h) alone does not induce apoptosis in HCT116 colorectal cancer cells, but enhances irinotecan-induced apoptosis in a concentration-dependent manner[1].
ATM-IN-13 (A36) has good metabolic stability in human and rat liver microsomes and mouse/rat plasma, poor stability in mouse liver microsomes, and excellent aqueous solubility of 1258.1 μg/mL at 25°C (pH 7)[1].
ATM-IN-13 (A36) has low potential for drug-drug interactions, with IC50 > 30 μM for inhibition of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4[1].
