| 体外研究活性 | KU-55933是有效的特定ATM抑制剂，IC50为13 nM，Ki值为2.2 nM。KU-55933也抑制DNA-PK和PI3K，IC50分别为2.5和16.6 μM。KU-55933也抑制mTOR活性，IC50为9.3 μM。KU-55933有效作用于ATM依赖的磷酸化作用。KU-55933抑制ATM依赖的磷酸化作用，存在剂量依赖性，IC50为300 nM。小于30 μM时，KU-58050不能抑制p53的ATM-依赖性磷酸化作用（位点为第15位丝氨酸）。在UV-诱导的H2AX（位点为第139位丝氨酸）, NBS1（位点为第343为丝氨酸）, CHK1（位点为第345位丝氨酸）,及SMC1（位点为第966位丝氨酸）中，加入KU-55933没有明显作用效果。紫外处理时，KU-55933切除由电离辐射诱导的ATM磷酸化底物。KU-55933使HeLa细胞对电离辐射敏感。在癌细胞中，KU-55933抑制生长因子诱导的Akt的磷酸化作用。KU-55933抑制癌细胞增殖。KU-55933抑制ATM，通过阻断下游TAp63α的激活，提高存活力。[2] | |||

| 方法 | U2OS细胞经过电离辐射(3, 5, 或15 Gy) 或者UV处理(5或50 J/m2)，通过p-p53（Ser15）和p53 的Western blot分析而测定ATM反应。在不同时间点获得细胞萃取物，SDS-PAGE分离蛋白，加入p-p53(Ser15)抗体，ATM增多。加入p53抗体观察到p53随着时间变化趋于稳定。为了测定KU-55933的IC50值，使用p-p53(Ser15)抗体检测KU-55933抑制ATM的效果。KU-55933加到细胞中，预温育1小时，然后进行电离辐射。在体外，使用扫描密度测定法测定IC50值。 |
