We have previously shown that hydroxyethylamines can be potent inhibitors of the BACE1 enzyme and that the generation of BACE1 inhibitors with CYP 3A4 inhibitory activities in this scaffold affords compounds (e.g., 1) with sufficient bioavailability and pharmacokinetic profiles to reduce central amyloid-β peptide (Aβ) levels in wild-type rats following oral dosing. In this article, we describe further
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。
