Recently, we reported potent and small-sized beta-secretase (BACE1) inhibitors KMI-420 and KMI-429 in which we replaced the Glu residue at the P4 position of KMI-260 and KMI-360, respectively, with a 1H-tetrazole-5-carbonyl DAP (L-alpha,beta-diaminopropionic acid) residue. At the P1' position, these compounds contain one or two carboxylic acid groups, which are unfavorable for crossing the blood-brain
最近,我们报道了强效和小型β-分泌酶(BACE1)抑制剂KMI-420和KMI-429,其中我们分别用1H-四唑取代了KMI-260和KMI-360的P4位置的Glu残基-5-羰基DAP(L-α,β-二氨基丙酸)残基。这些化合物在P1'位置含有一个或两个羧酸基团,不利于穿越血脑屏障。在本文中,我们报道了具有P1'羧酸生物异构体的BACE1抑制剂,以开发实用的抗阿尔茨海默氏病药物。其中,含四唑环的化合物KMI-570(IC50 = 4.8 nM)和KMI-684(IC50 = 1.2 nM)表现出显着的BACE1抑制活性。
