Here we demonstrate that the treatment of intracellular tachyzoites with the PI3K inhibitor caffeine or ATM kinase-inhibitor KU-55933 affects parasite replication rate in a dose-dependent manner. KU-55933 affects intracellular tachyzoite growth and induces G1-phase arrest.

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 affects intracellular tachyzoite growth and induces G1-phase arrest. KU55933 and caffeine abrogate ADR-induced early accumulation of E2F1 in the nucleolus. H1299 cells were pretreated with ATM/ATR inhibitor caffeine (100 μM) or ATM-specific inhibitor KU55933 (250 nM) for 30 min followed by exposure to ADR (1 μM) for 6 h. KU55933, which suppresses ATM phosphorylation upon irradiation, could be applied in the radiotherapy of BCa patients with a DAB2IP gene defect. The established ATM inhibitor KU55933 was used as a positive control for ATM inhibition (24). IR-induced ATM kinase activity resulted in the expected increases in ATM-dependent phosphorylation events and CP466722 treatment inhibited all of these events. ATP-competitive ATM inhibitors like KU-55933 might act in a similar way as kd ATM protein, which, upon prolonged exposure, may cause greater side effects in vivo than a loss of ATM protein expression would.

IC 50 & Target [1] ATM Here we demonstrate that the treatment of intracellular tachyzoites with the PI3K inhibitor caffeine or ATM kinase-inhibitor KU-55933 affects parasite replication rate in a dose-dependent manner. 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 . KU55933, which suppresses ATM phosphorylation upon irradiation, could be applied in the radiotherapy of BCa patients with a DAB2IP gene defect.

KU55933 and caffeine abrogate ADR-induced early accumulation of E2F1 in the nucleolus. H1299 cells were pretreated with ATM/ATR inhibitor caffeine (100 μM) or ATM-specific inhibitor KU55933 (250 nM) for 30 min followed by exposure to ADR (1 μM) for 6 h.

ATM manufacturers are developing numerous ways to add to the so-called convenience society that ATMs helped initiate.

As an ATM inhibitor, KU-55933 significantly inhibited the increase of pho We had previously identified KU55933 as a potent and selective inhibitor of ATM , and subsequently KU600019 has been identified as a more potent ATM inhibitor Unfortunately, although these compounds provided in vitro evidence that inhibiting ATM induced chemo- and radiosensitization in tumor cell lines, to date, there have been no in vivo investigations with small-molecule ATM inhibitors. KU-55933 (ATM Kinase Inhibitor)是一种有效的，特异性 ATM 抑制剂，在无细胞试验中 IC50 / Ki 为12.9 nM/2.2 nM，与DNA-PK， PI3K/PI4K， ATR和mTOR相比，对ATM具有高度选择性。.

Functional Studies - KU-55933, competitive ATM kinase inhibitor (ab120637) HepG2 cells were incubated at 37°C for 60 minutes with vehicle control (0 µM) and different concentrations of KU-55933 (ab120637). As an ATM inhibitor, KU-55933 significantly inhibited the increase of phospho-Akt at Ser473 in MDA-MB-453 and PC-3 cells treated with insulin and IGF-I following serum starvation. In the MTT assay, KU-55933 treatment suppressed cell proliferation by about 50% at concentration of 10 μM in MDA-MB-453 and PC-3 cells.
