Verubecestat 3 (MK-8931), a diaryl amide-substituted 3-imino-1,2,4-thiadiazinane 1,1-dioxide derivative, is a high-affinity β-site amyloid precursor protein cleaving enzyme 1 (BACE1) inhibitor currently undergoing Phase 3 clinical evaluation for the treatment of mild to moderate and prodromal Alzheimer’s disease. Although not selective over the closely related aspartyl protease BACE2, verubecestat has
Verubecestat 3(MK-8931)是一种由二芳基酰胺取代的3-亚氨基-1,2,4-噻二氮烷1,1-二氧化物衍生物,目前是一种高亲和力的β位淀粉样蛋白前体蛋白裂解酶1(BACE1)抑制剂。正在接受治疗轻度至中度和前驱性阿尔茨海默氏病的3期临床评估。尽管对密切相关的天冬氨酰蛋白酶BACE2没有选择性,但是verubecestat对BACE1的选择性比其他主要天冬氨酰蛋白酶(尤其是组织蛋白酶D)高,并且可以显着降低大鼠和非人类灵长类动物的CSF和脑Aβ水平以及人类的CSFAβ水平。在此注释中,我们描述了3的发现,包括围绕新型亚氨二氮杂二嗪烷核心的设计,验证和选择的SAR以及其临床前和1期临床表征的各个方面。
