We previously identified a spiro[piperidine-4,1-pyrido[3,4-b]indole] class of co-potentiators that function in synergy with existing CFTR potentiators such as VX-770 or GLGP1837 to restore channel activity of a defined subset of minimal function cystic fibrosis transmembrane conductance regulator (CFTR) mutants. Here, structure-activity studies were conducted to improve their potency over the previously
我们之前确定了一种螺[哌啶-4,1-吡啶并[3,4-b]吲哚]类共增强剂,它们与现有的 CFTR 增强剂(如 VX-770 或 GLGP1837)协同作用,以恢复定义子集的通道活性最小功能囊性纤维化跨膜电导调节器 (CFTR) 突变体。在这里,进行了结构-活性研究以提高其对先前鉴定的化合物20(最初称为 CP-A01)的效力。37 螺[哌啶-4,1-吡啶并[3,4-b]吲哚]的靶向合成通常使用通用的两步或三步反应方案完成,每一步都具有高效率。构效关系研究确定类似物2i具有 6'-甲氧基吲哚和 2,4,5-三氟苄基取代基,具有最大的激活 N1303K-CFTR 的效力,EC 50 ∼600 nM 比小分子筛选中鉴定的原始化合物提高了约 17 倍.
