生物活性

產品描述 Ceralasertib (AZD6738) 是一種口服具有活性的,選擇性 ATR 激酶抑制劑,IC50 為 1 nM。Phase 1/2。
靶點
ATR [1]
(Cell-free assay)
1 nM
體外研究(In Vitro)
體外研究活性

在四個Kras突變細胞系:H23,H460,A549,和H358中,AZD6738抑制ATR激酶活性,并損害細胞活性。在ATM缺失的H23細胞中,AZD6738強烈增強順鉑誘導快速細胞死亡的作用。[1]在p53 或 ATM缺失的細胞中,AZD6738治療引起復制叉停滯和未修復DNA損傷的積累,導致有絲分裂障礙,從而使細胞死亡。[2]

細胞實驗 細胞系 H23,H460,A549,和 H358 細胞
濃度 ~30 μM
孵育時間 48小時
方法

細胞在白色壁,透明底的96孔板中與指示劑量的AZD6738,NSC 119875,LY188011,或它們的組合處理48小時。ATP水平通過CellTiter-Glo發(fā)光細胞活性試驗和Safire2酶標儀測量代替品活性評估。進一步分析之前,原始數據對本底發(fā)光進行校正。對于AZD6738治療,在GraphPad Prism 6中將對數轉化(x=log(x))的數據歸一化為未處理對照組的平均值,通過非線性回歸(log(抑制劑) vs. 對可變斜率的響應值) 生成對數劑量響應曲線。GI50值,定義為Y = 50%時,X的劑量,根據劑量反應曲線推導得出。

體內研究活性

在負荷H460和H23腫瘤的裸鼠中,AZD6738 (50 mg/kg, p.o.)導致腫瘤生長抑制(TGI),結合順鉑引起ATM缺失的H23腫瘤快速退化。[1]在負荷LoVo異種移植物的裸鼠中,AZD6738 (50 mg/kg) + IR (2 Gy)的組合避免了毒性,同時仍保持療效。[3]
