体外研究(In Vitro)
体外研究活性

在四个Kras突变细胞系:H23,H460,A549,和H358中,AZD6738抑制ATR激酶活性,并损害细胞活性。在ATM缺失的H23细胞中,AZD6738强烈增强顺铂诱导快速细胞死亡的作用。[1]在p53 或 ATM缺失的细胞中,AZD6738治疗引起复制叉停滞和未修复DNA损伤的积累,导致有丝分裂障碍,从而使细胞死亡。[2]

浓度 ~30 μM
孵育时间 48小时
方法

细胞在白色壁,透明底的96孔板中与指示剂量的AZD6738,NSC 119875,LY188011,或它们的组合处理48小时。ATP水平通过CellTiter-Glo发光细胞活性试验和Safire2酶标仪测量代替品活性评估。进一步分析之前,原始数据对本底发光进行校正。对于AZD6738治疗,在GraphPad Prism 6中将对数转化(x=log(x))的数据归一化为未处理对照组的平均值,通过非线性回归(log(抑制剂) vs. 对可变斜率的响应值) 生成对数剂量响应曲线。GI50值,定义为Y = 50%时,X的剂量,根据剂量反应曲线推导得出。

在负荷H460和H23肿瘤的裸鼠中,AZD6738 (50 mg/kg, p.o.)导致肿瘤生长抑制(TGI),结合顺铂引起ATM缺失的H23肿瘤快速退化。[1]在负荷LoVo异种移植物的裸鼠中,AZD6738 (50 mg/kg) + IR (2 Gy)的组合避免了毒性,同时仍保持疗效。[3]
