In this study, the TMZ sensitizing effects of 2 ATM specific inhibitors were studied in established and xenograft-derived glioblastoma (GBM) lines that are inherently sensitive to TMZ and derivative TMZ-resistant lines. KU-55933是一种特异性的ATM激酶抑制剂，IC50值为13 nM[1]。ATM可以刺激Akt的Ser473磷酸化，介导胰岛素诱导的Akt充分激活。在血清饥饿后用胰岛素和IGF-I处理的MDA-MB-453和PC-3细胞中，作为ATM的抑制剂，KU-55933显著抑制Akt Ser473磷酸化的增加。 In this paper, we identified the nontoxic compound CP466722 as an inhibitor of ATM and offer a comparison to the established ATM inhibitor KU55933 ( 24). In response to IR, ATM initiates a signaling cascade and phosphorylates downstream targets (e.g., p53, Chk2, and SMC1) on characteristic sites which can be used as a measure of cellular ATM kinase activity ( 8 , 10 , 11 , 13 ). ku-55933 atm kinase inhibitor. high purity, best price.

To determine if pharmacological inactivation of ATM has similar effects as genetic inactivation, we used the ATM kinase inhibitor KU55933. Potent and selective ATM kinase inhibitor IC 50 s= 13, 2500, 9300, 16600, >100000 and >100000 nM for ATM, DNA-PK, mTOR, PI 3-kinase, PI 4-K and ATR respectively. 1 Decreases viability of MCF-7, A549 and HCT116 cells and decreases p21 CIP1 levels in vitro. 2 Disruption of ATM signaling in primary A-T fibroblasts leads to dysregulation of ribonucleotide reductase and increase resistance to KU-55933A is a potent, selective and ATP-competitive inhibitor of ATM Kinase (Ki = 2.2 nM; IC₅₀ = 13 nM).

KU-55933 affects intracellular tachyzoite growth and induces G1-phase arrest. In this study, we have observed that in contrast to the ATM selective inhibitor KU55933, ATM/ATR dual inhibitors such as caffeine and CGK733 can suppress cyclin D1 levels in cancer cell lines. A recent study suggests that mitogen-activated cyclin D1 expression is required for the induction of premature senescence .

KU-55933 is a potent and selective ATP-competitive inhibitor of ATM kinase (IC50 = 13 nM  ATM Kinase Inhibitor (KU 55933) is a cell-permeable, potent, selective and ATP- competitive inhibitor of ATM (Ataxia telangiectasia mutated), a serine/threonine  5 Apr 2016 For example, KU55933, a specific inhibitor of the protein kinase ataxia- telangiectasia mutated (ATM), which is a key player in the signaling  Phosphorylation of ATM on S1981 is inhibited by ATMi, consistent with the anticipated The KU55933 ATM inhibitor used was from Kudos Pharmaceuticals   23 Apr 2018 A number of selective inhibitors of ATM have been disclosed, the first of which, 2 ( KU-55933), was developed by KuDOS Pharmaceuticals (now  KU-55933 is a specific ATM inhibitor, which has pro-apoptotic effect on tumor cells. In this study, we analyzed the synergistic effect of sorafenib and KU-55933   DNA repair inhibitors as radiosensitizers in human lung cells kinase (DNA-PK); KU55933 (10 μM), an inhibitor of ataxia-telangiectasia mutated kinase (ATM);  KU55933 is a potent and selective ATP-competitive inhibitor of ATM, with an IC50 of 13 nmol/l and a Ki of 2.2 nmol/l.
