recently reported to possess excellent mineralocorticoid receptor (MR) antagonist in vitro potency and no calcium channel-blocker (CCB) activity. In the present study, we report the structure−activity relationships of this novel series of cyano ester dihydropyridines that resulted in R6 substituted analogues with improved metabolic stability while maintaining excellent MR antagonist activity and selectivity
最近报道了一种新的1,4-二氢吡啶5a,在C3位上含有一个氰基,在体外具有出色的盐皮质激素受体(MR)拮抗剂,并且没有钙通道阻滞剂(CCB)活性。在本研究中,我们报道了这种新颖的氰基酯二氢吡啶类新序列的结构活性关系,该关系导致R 6取代的类似物具有改善的代谢稳定性,同时保持出色的MR拮抗剂活性和对其他核受体的选择性。通过在R 6处引入五元环杂环进一步优化结构所产生的化合物具有出色的MR拮抗剂效价和合适的药代动力学特征。在对Dahl盐敏感的高血压大鼠模型中有前途的工具化合物的体内研究表明,降压(BP)与类固醇MR拮抗剂依普利农相似,为非类固醇,口服有效的MR拮抗剂提供了概念验证(POC) 。
