Ivacaftor(10 μM) 作用于表達CFTR突變型G551D的Fisher 大鼠甲狀腺(FRT) 細胞,顯著提高forskolin-刺激的Cl-分泌(IT),提高~4倍,EC50為100 nM,作用于表達CFTR突變型F508del進程的重組細胞,提高6倍,EC50為25 nM。與提高forskolin刺激的IT相一致,Ivacaftor(10 μM) 提高G551D-, F508del-, 和野生型CFTR 的開放概率(Po),分別提高~6倍,~5倍 和~2倍。說明Ivacaftor 直接作用于CFTR,而提高活性。Ivacaftor(10 μM)作用于攜帶G551D 和F508del CFTR 突變型的原代培養(yǎng)的人 CF 支氣管上皮細胞(HBE),有效提高 forskolin-刺激的IT,提高10倍,從5%提高到最高水平48%,EC50為236 nM,有效性比通常使用的CFTR 增強劑Genistein高70多倍,EC50 為16 μM。Ivacaftor作用于攜帶F508del純合子CFTR的HBE, 顯著提高forskolin刺激的IT,EC50為22 nM, 從4%提高到16%。因為CFTR增強, Ivacaftor抑制過多ENaC-調(diào)節(jié)的Na+和液體吸收,IC50為43 nM, 且作用于G551D/F508del HBE,降低反應(yīng), 導(dǎo)致表面液體和纖毛擺動頻率(CBF)提高。[1]
