DNA-dependent protein kinase (DNA-PK) binds to strand breaks produced during normal cellular processes or in response to genotoxic stresses, such as ionizing radiation, targeting substrates that facilitate DNA repair. NU 7026 is a cell-permeable, potent, specific, and ATP-competitive inhibitor of DNA-PK (IC50 = 230 nM).{17273} It poorly inhibits phosphioinositide 3 kinase (IC50 = 13 ?M) and is inactive against ataxia telangiectasia mutated kinase, ATR, and poly (ADP-ribose) polymerase.{17273} NU 7026 impairs cellular DNA double strand break repair and decreases survival in cells exposed to ionizing radiation.{17273} It also potentiates the cytotoxicity of topoisomerase II poisons used in the treatment of leukemia. For example, it potentiates the growth inhibitory effects of mitoxantrone in K562 cells more than 10-fold.{17274}
