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] |

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。 |

動物體內配方計算器(澄清溶液)
第一步:請輸入基本實驗信息(考慮到實驗過程中的損耗,建議多配一只動物的藥量)
第二步:請輸入動物體內配方組成(配方適用于不溶于水的藥物;不同批次藥物配方比例不同,請聯(lián)系Selleck為您提供正確的澄清溶液配方)
計算結果:
工作液濃度: mg/ml;
DMSO母液配制方法: mg 藥物溶于μL DMSO溶液(母液濃度mg/mL,注:如該濃度超過該批次藥物DMSO溶解度,請先聯(lián)系Selleck);
體內配方配制方法:取μL DMSO母液,加入μL PEG300,混勻澄清后加入μL Tween 80,混勻澄清后加入μL ddH2O,混勻澄清。
體內配方配制方法:取μL DMSO母液,加入μL Corn oil,混勻澄清。
注意:1. 首先保證母液是澄清的;
2.一定要按照順序依次將溶劑加入,進行下一步操作之前必須保證上一步操作得到的是澄清的溶液,可采用渦旋、超聲或水浴加熱等物理方法助溶。
