KU 55933,587871-26-9,IC-0236435
KU-55933 is a specific inhibitor of ATM kinase with IC50 value of 13 nM [1].
ATM can stimulate Ser473 phosphorylation of Akt and mediate its full activation in response to insulin. 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. In a panel of cell lines that have varied Akt activities, KU-55933 treatment caused cell proliferation inhibition correlated with the Akt phosphorylation. KU-55933 was also found to induce G1 cell cycle arrest through down-regulating the cyclin D1 level in MDA-MB-453 and PC-3 cells [2].
