  Design and Preparation of a Potent Series of Hydroxyethylamine Containing β-Secretase Inhibitors That Demonstrate Robust Reduction of Central β-Amyloid

  摘要：

  A series of potent hydroxyethyl amine (HEA) derived inhibitors of beta-site APP cleaving enzyme (BACE1) was optimized to address suboptimal pharmacokinetics and poor CNS partitioning. This work identified a series of benzodioxolane analogues that possessed improved metabolic stability and increased oral bioavailability. Subsequent efforts focused on improving CNS exposure by limiting susceptibility to Pgp-mediated efflux and identified an inhibitor which demonstrated robust and sustained reduction of CNS beta-amyloid (A beta) in Sprague-Dawley rats following oral administration.

  有效的，口服有效的羟乙基胺衍生的β-位淀粉样前体蛋白裂解酶（BACE1）抑制剂的设计与合成

  摘要：

  先前我们已经证明羟乙胺可能是BACE1酶的有效抑制剂，并且在该支架中具有CYP 3A4抑制活性的BACE1抑制剂的产生提供了具有足够生物利用度和药代动力学特征的化合物（例如1），以减少中央淀粉样β肽（口服给药后野生型大鼠的Aβ）水平。在本文中，我们描述了羟乙胺系列的P1-苯环的进一步修饰，以提供有效的双BACE1 / CYP 3A4抑制剂，该抑制剂表现出对CNS的改善渗透性。这些化合物中的几种引起口服给药后大鼠CSF和大脑中Aβ含量的强烈降低，并且化合物37的心血管安全性相对于1有所改善。

  beta-Secretase inhibitors are potentially disease-modifying treatments for Alzheimer's disease. Previous efforts in our laboratory have resulted in hydroxyethylamine-derived inhibitors such as 1 with low nanomolar potency against beta-site amyloid precursor protein cleaving enzyme (BACE). When dosed intravenously, compound 1 was also shown to significantly reduce A beta(40) levels in plasma, brain, and cerebral spinal fluid. Herein, we report further optimizations that led to the discovery of inhibitor 16 as a novel, potent, and orally efficacious BACE inhibitor.
