| Description | Potent and selective ATM kinase inhibitor IC50s= 13, 2500, 9300, 16600, >100000 and >100000 nM for ATM, DNA-PK, mTOR, PI 3-kinase, PI 4-K and ATR respectively.1Decreases viability of MCF-7, A549 and HCT116 cells and decreases p21CIP1?levels?in vitro.2?Disruption of ATM signaling in primary A-T fibroblasts leads to dysregulation of ribonucleotide reductase and increase resistance to inhibitors of mitochondrial respiration and translation.3?Sensitizes radio-resistant cancer cells.4Provides neuroprotection against H2O2-induced cell damage.5 | | Uses | KU-55933 has been used as an ataxia-telangiectasia mutated (Atm) inhibitor. | | Uses | A potent and specific ATM kinase inhibitor with an IC50 and a Ki of 13 nM and 2.2 nM, respectively. | | Definition | ChEBI: 2-(4-morpholinyl)-6-(1-thianthrenyl)-4-pyranone is a thianthrene. | | Biological Activity | Potent, selective and competitive ATM kinase inhibitor (K i = 2.2 nM, IC 50 values are 13, 2500, 9300, 16600, > 100000 and > 100000 nM at ATM, DNA-PK, mTOR, PI 3-kinase, PI 4-K and ATR respectively). Decreases viability of MCF-7, A549 and HCT116 cells and decreases p21 CIP1 levels in vitro . Acts as a radio- and chemosensitizer for the treatment of cancer. | | Biochem/physiol Actions | KU-55933 is a very potent, specific inhibitor of Ataxia telangiectasia (A-T) mutated (ATM) kinase (IC50 = 13 nM). KU-22933 treatment sensitizes cancer cells to ionizing radiation and cytotoxic drugs. The compound KU-22933 blocks ATM-mediated phosphorylyation of p53, gH2AX, NBS1, and SMC1. | | storage | Desiccate at -20°C | | References | 1) Hickson?et al.?(2004),?Identification and characterization of a novel and specific inhibitor of the ataxia-telangiectasia mutated kinase ATM; Cancer Res.,?64?9152
