The action of the aspartyl protease renin is the rate-limiting initial step of the renin-angiotensin-aldosterone system. Therefore, renin is a particularly promising target for blood pressure as well as onset and progression of cardiovascular and renal diseases. New pyrimidine derivatives 5–14 were designed in an attempt to enhance the renin inhibitory activity of compound 3 identified by our previous
天冬氨酰蛋白酶肾素的作用是肾素-血管紧张素-醛固酮系统的限速起始步骤。因此,肾素是血压以及心血管和肾脏疾病的发作和发展的特别有希望的靶标。设计新的嘧啶衍生物5 – 14是为了增强化合物3的肾素抑制活性,这种化合物是通过我们以前的基于片段的药物设计方法确定的。引入对于在催化位点与两种天冬氨酸相互作用必不可少的碱性胺,并优化S1 / S3结合元素,包括通过Leu114诱导拟合的结构改变(Leu114由“ Leu-in”变为“ Leu-out”)。基于合理结构的药物设计方法导致了N的发现-(piperidin-3-yl)pyrimidine-5-carboxamide 14,比化合物3强65,000倍的有效肾素抑制剂。出人意料的是,化合物14的抑制活性的这种显着增强已经通过仅向化合物3整体添加七个重原子而实现。化合物14在大鼠中显示出优于其他天冬氨酰蛋白酶的优异选择性和中等的口服生物利用度。
