are our efforts directed toward improving both the pharmacokinetic profile as well as the AT(1) and ET(A) receptor potency of 3. Our efforts centered on modifying the 2'-side chain of 3 and examining the isoxazolylsulfonamide moiety in 3. This effort resulted in the discovery of 7 as a highly potent second-generation DARA. Compound 7 also showed substantially improved pharmacokinetic properties compared
在先前的报告中,我们证明了将AT(1)受体拮抗剂(1,厄贝沙坦)中存在的关键结构元素与联苯磺酰胺ET(A)受体拮抗剂(2)中的关键结构元素合并在一起,然后进行额外的优化,从而提供了化合物3一种双作用受体拮抗剂(DARA),可有效阻断AT(1)和ET(A)受体。本文描述的是我们致力于改善3的药代动力学以及AT(1)和ET(A)受体效能的努力。我们的努力集中于修饰3的2'侧链和检查3中的异恶唑基磺酰胺部分这项工作导致了7作为高效第二代DARA的发现。与3相比,化合物7还显示出显着改善的药代动力学特性。与单独使用DARA 3或AT(1)或ET(A)受体拮抗剂相比,DARA 7可以更大程度和更长的持续时间降低静脉注射Ang II或大ET-1引起的血压升高。在正常的高血压SHR模型中,化合物7以剂量依赖的方式清楚地显示了优于厄贝沙坦(一种AT(1)受体拮抗剂)的优越性,表明在单个分子中AT(1)和ET(A)受体阻滞剂的协同作用。
