体外研究活性

Ivacaftor(10 μM) 作用于表达CFTR突变型G551D的Fisher 大鼠甲状腺(FRT) 细胞,显著提高forskolin-刺激的Cl-分泌(IT),提高~4倍,EC50为100 nM,作用于表达CFTR突变型F508del进程的重组细胞,提高6倍,EC50为25 nM。与提高forskolin刺激的IT相一致,Ivacaftor(10 μM) 提高G551D-, F508del-, 和野生型CFTR 的开放概率(Po),分别提高~6倍,~5倍 和~2倍。说明Ivacaftor 直接作用于CFTR,而提高活性。Ivacaftor(10 μM)作用于携带G551D 和F508del CFTR 突变型的原代培养的人 CF 支气管上皮细胞(HBE),有效提高 forskolin-刺激的IT,提高10倍,从5%提高到最高水平48%,EC50为236 nM,有效性比通常使用的CFTR 增强剂Genistein高70多倍,EC50 为16 μM。Ivacaftor作用于携带F508del纯合子CFTR的HBE, 显著提高forskolin刺激的IT,EC50为22 nM, 从4%提高到16%。因为CFTR增强, Ivacaftor抑制过多ENaC-调节的Na+和液体吸收,IC50为43 nM, 且作用于G551D/F508del HBE,降低反应, 导致表面液体和纤毛摆动频率(CBF)提高。[1]

%DMSO %

计算结果:

工作液浓度: mg/ml;

DMSO母液配制方法: mg 药物溶于μL DMSO溶液(母液浓度mg/mL,:如该浓度超过该批次药物DMSO溶解度,请先联系Selleck);

体内配方配制方法:μL DMSO母液,加入μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入μL ddH2O,混匀澄清。

体内配方配制方法:μL DMSO母液,加入μL Corn oil,混匀澄清。

注意:1. 首先保证母液是澄清的;
2.一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
