KU 59403 is a potent ATM inhibitor, with IC 50 values of 3 nM, 9.1 μM and 10 μM for ATM, DNA-PK and PI3K, respectively.
性状
Solid
IC50 & Target[1][2]
IC50: 3 nM (ATM).
体外研究(In Vitro)
KU 59403 (1 μM) enhances VP-16 (1 μM) cytotoxicity to a similar extent in HCT116 and HCT116-N7 cells, and in the p53 mutant SW620 cells and human breast cancer cell line, MDAMB-231, sensitisation is 11.9±4.7 and 3.8±1.8-fold respectively. Inhibition of IR-induced ATM activity by KU 59403 (1 μM) is approximately 50% in MDA-MB231 cells and >50% in HCT116 cells that have low ATM expression and activity. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
KU59403 with a single daily dose of 12.5 mg/kg causes a significant sensitization.
Increasing the dose of KU59403 to 25 mg/kg given twice daily results in the greatest chemo-sensitisation with a 3-fold increase in BMY-40481-induced tumour growth delay in both SW620 and HCT116-N7 xenografts, in the absence of a significantly increased toxicity. has not independently confirmed the accuracy of these methods. They are for reference only.
