further development. To overcome these shortcomings, the structure modification of thienoquinoline was carried out in this study, which led to the discovery of novel thienopyridine derivatives as specific urea transporter inhibitors. Further optimization obtained the promising preclinical candidate 8n with not only excellent inhibition effect on urea transporters and diuretic activity on rat model, but
尿素转运蛋白(UTs)在尿液浓缩机制中起着重要作用,被公认为是开发具有保盐利尿活性的小分子抑制剂的新型靶标。硫喹啉衍生物是我们小组确定的一类新型UT-B抑制剂,在动物模型中起着重要的利尿作用。然而,差的溶解度和低的生物利用度限制了它的进一步发展。为了克服这些缺点,本研究对噻吩并喹啉进行了结构修饰,从而发现了新型噻吩并吡啶衍生物作为特定的尿素转运蛋白抑制剂。进一步的优化获得了有希望的临床前候选药物8n 对大鼠模型的尿素转运蛋白和利尿活性均具有优异的抑制作用,还具有一定的水溶性和Log P值。
