KU-55933 (ATM Kinase Inhibitor)是一种特异性的ATM抑制剂,IC50/Ki为12.9 nM/2.2 nM,与DNA-PK, PI3K/PI4K, ATR和mTOR相比,作用于ATM具有高度选择性。
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.

动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
