reported the fragment-based discovery of LY2811376, the first BACE1 inhibitor reported to demonstrate robust reduction of human CSF Aβ in a Phase I clinical trial. We also reported on the discovery of LY2886721, a potent BACE1 inhibitor that reached phase 2 clinical trials. Herein we describe the preparation and structure activity relationships (SAR) of a series of BACE1 inhibitors utilizing trans-cyclopropyl
在寻找疾病改良剂以减缓阿尔茨海默氏病的进展中,BACE1的抑制已成为重要的策略。我们先前报道了LY2811376的基于片段的发现,LY2811376是第一个BACE1抑制剂,据报道在一项I期临床试验中证明了人CSFAβ的强烈降低。我们还报告了LY2886721的发现,LY2886721是一种有效的BACE1抑制剂,已达到2期临床试验。在这里,我们描述了一系列利用反式环丙基部分作为构象约束条件的BACE1抑制剂的制备和结构活性关系(SAR)。描述了这些BACE1抑制剂的设计,立体化学复杂的有机合成的详细信息以及生物学活性。
