| 体外研究 | CP-466722(CP466722,6-10μM)抑制IR诱导的ATM激酶活性,并且抑制可以快速且完全逆转。 CP466722(6,10μM)抑制小鼠细胞中p53诱导和ATM依赖性磷酸化,但CP466722不能抑制Chk1的ATR活性和ATR依赖性磷酸化。 CP466722(6μM)破坏细胞中依赖ATM的细胞周期检查点[1]。 CP466722(1μM)完全抑制MCF7细胞中的ATM依赖性磷酸化。 CP466722(10μM)可降低MCF7细胞中的pKAP1磷酸化,IC50为0.41μM。 CP466722(10μM)抑制pATM和pKAP1信号[2]。 CP-466722(CP466722,5-50μM)比MCF-7癌细胞更强烈地抑制SKBr-3癌细胞的增殖。 CP466722(10μM)在处理48小时后也略微增加了G1期MCF-7和SKBr-3细胞的比例[3]。 |
| 激酶实验 | 为了筛选ATM激酶活性的小分子抑制剂，进行体外激酶测定，并开发ELISA测定法，其测量ATM下游靶标p53的磷酸化状态。纯化重组GST-p53（1-101）和全长Flag标记的ATM和ATR用于ELISA和体外激酶测定。简言之，将Nunc 96孔Maxisorp板用PBS中的2μg纯化的重组GST-p53（1-101）包被过夜（4℃）。所有后续孵育均在室温下进行。将板洗涤（0.05％v / v-Tween / PBS），然后加入纯化的重组全长ATM激酶（30-60ng），最终体积为80μL反应缓冲液（20mM HEPES，50mM NaCl2，在化合物存在或不存在下，10mM MgCl 2,10mM MnCl 2,1mM DTT和1μMATP）。将包括CP-466722（10μM）的化合物一式两份加入板中，并孵育激酶测定法（90分钟）。洗涤平板（0.05％v / v-吐温/ PBS），封闭（1小时，1％w / v-BSA / PBS）并在抗磷酸化（Ser15）-p53抗体（1：1000 / PBS）之前冲洗。加入板中并孵育（1小时）。为了减少非特异性结合板，在用HRP缀合的山羊抗兔IgG二抗（1：5000 / PBS）温育（1小时）之前洗涤（0.05％v / v-Tween / PBS）。用TMB底物试剂检测与磷酸化GST-p53（1-101）蛋白连接的二抗。开发平板（15-30分钟）并在确定吸光度（λ450nm）之前停止反应（1M H 2 SO 4终浓度）。在ELISA测定中抑制ATM激酶活性的化合物的特征在于使用体外激酶测定法抑制ATM / ATR激酶。使用抗磷酸化（Ser15）-p53抗体的Western印迹用作ATM / ATR抑制的读数[1]。 |
| 细胞实验 | 将细胞一式三份（40,000个细胞/板）铺板，根据需要孵育，然后将培养基和胰蛋白酶消化的细胞组合并测定活力：Vi-CELL TM XR细胞活力分析仪[1]。 |
