描述 | The ataxia-telangiectasia mutated (ATM) protein kinase is a master regulator of the DNA damage response (DDR), and it coordinates checkpoint activation, DNA repair, and metabolic changes in eukaryotic cells in response to DNA double-strand breaks and oxidative stress[1]. AZD1390 is a potent, highly selective, orally bioavailable, brain-penetrant ATM inhibitor with an IC50 of 0.78 nM in cell[2]. AZD1390 blocks ATM-dependent DDR pathway activity and combines with radiation to induce G2 cell cycle phase accumulation, micronuclei, and apoptosis. AZD1390 radiosensitizes glioma and lung cancer cell lines, with p53 mutant glioma cells generally being more radiosensitized than wild type[2]. In in vivo syngeneic and patient-derived glioma as well as orthotopic lung-brain metastatic models, AZD1390 dosed in combination with daily fractions of ionizing radiation (IR) (whole-brain or stereotactic radiotherapy) significantly induced tumor regressions and increased animal survival compared to IR treatment alone[2]. |
