The macrocyclic peptidic BACE-1 inhibitors 2a–c show moderate enzymatic and cellular activity. By exchange of the hydroxyethylene- to ethanolamine-transition state mimetic the peptidic character was reduced, providing the highly potent and selective inhibitor 3. Variation of the P′ moiety resulted in the macrocyclic inhibitor 14. Both macrocycles show inhibition of BACE-1 in the brain of APP51/16 transgenic
大环肽BACE-1抑制剂2a – c显示中等的酶和细胞活性。通过交换羟基乙烯到乙醇胺的过渡态模拟物,降低了肽的特性,从而提供了高效且选择性强的抑制剂3。P'部分的变化产生了大环抑制剂14。两种大环化合物均在APP51 / 16转基因小鼠的大脑中显示出BACE-1的抑制作用,静脉注射后为3(NB-544),口服后为14(NB-533)。
