using cell-based assays, of a series of benzoflavone analogues to examine structure-activity relationships and to identify compounds having greater potency for activation of both wild type CFTR and a mutant CFTR (G551D-CFTR) that causes cystic fibrosis in some human subjects. Using UCCF-029 as a structural guide, a panel of 77 flavonoid analogues was prepared. Analysis of the panel in FRT cells indicated
我们以前对黄酮类化合物和相关杂环的筛选具有激活囊性纤维化跨膜电导调节剂(CFTR)氯化物通道的能力,这表明UCCF-029是一种7,8-苯并黄酮,是一种有效的活化剂。在本研究中,我们描述了使用基于细胞的分析方法对一系列苯并黄酮类似物进行合成和评估,以检查其结构活性关系,并鉴定出对野生型CFTR和突变型CFTR(G551D -CFTR)在某些人类受试者中引起囊性纤维化。使用UCCF-029作为结构指导,制备了77种类黄酮类似物。对FRT细胞中面板的分析表明,黄酮A环在7,8位的苯环显着提高了化合物活性和几种类黄酮的效力。在3或4位上引入B环吡啶基氮也可提高CFTR活性,但这种结构修饰的影响不如苯甲环化均匀。最有效的新类似物UCCF-339以1.7 microM的K(d)激活了野生型CFTR,它比以前最有效的CFTR类黄酮活化剂芹菜素具有更高的活性。苯并黄酮类化合物中的几种化合物也可以活化G5
