IOWH-032是细胞外囊性纤维化跨膜传导调节因子(CFTR)有效的合成抑制剂,在基于T84和CHO-CFTR细胞的实验中,IC50值为1.01 μM[1]。CFTR氯离子通道是肠病原菌引起腹泻的主要驱动力,因此它是一种有吸引力的药物靶标。CFTR通过控制氯离子进出细胞,在跨上皮流体稳态中起重要作用,最终引起细胞内外的水分交换[1]。
体外实验:IOWH032抑制CFTR的活性,基于T84-CFTR细胞测定的IC50值为6.87 μM [1]。IOWH-032以浓度依赖性方式迅速阻断和加强hCFTR的活性,Kd值分别为6.1 nM和0.64 nM。然而,IOWH-032不能增强mCFTR的活性,阻断mCFTR的Kd值为42.9 μM[2]。
体内实验:在小鼠的闭环模型中,IOWH032显著抑制霍乱毒素(CTX)诱导的分泌。此外,在定制大鼠模型中,与对照组(霍乱毒素)相比,口服剂量为5 mg/kg的IOWH032将粪便产出指数减少70%[1]。
