发现和优化1-苯氧基-2-氨基茚满作为Na + / H + 3型交换子(NHE3)的有效,选择性和口服生物利用抑制剂
摘要:
基于高通量筛选(HTS)的命中,描述了作为3 + Na + / H +交换剂(NHE3)抑制剂的1-苯氧基-2-氨基茚满的设计,合成及其构效关系。化学最优化导致发现了以13d为最佳化合物的有效,选择性和口服生物利用的NHE3抑制剂,显示出较高的体外通透性和缺乏CYP2D6抑制作用作为主要优化参数。将1-苯氧基-2-氨基茚满对准13d的X射线结构然后为NHE3抑制捕获指南提供了3D-QSAR模型以进行优化。这些模型显示出良好的相关系数,并可以进行活性估算。在计算机中针对Caco-2渗透性和CYP2D6抑制作用的ADMET模型也已成功应用于该系列。此外,对接CYP2D6 X射线结构为3D-QSAR模型提供了可靠的对齐方式。最终,重命名为SAR197的13d在体外和体内药代动力学(PK)和药理研究中进行了表征,以揭示其减少阻塞性睡眠呼吸暂停的潜力。
