potential disease-modifying approach to the treatment of Alzheimer’s disease. Despite over a decade of drug discovery efforts, the identification of brain-penetrant BACE1 inhibitors that substantially lower CNS Aβ levels following systemic administration remains challenging. In this report we describe structure-based optimization of a series of brain-penetrant BACE1 inhibitors derived from an iminopyrimidinone
抑制 BACE1 以防止脑 Aβ 肽形成是治疗阿尔茨海默病的潜在疾病修饰方法。尽管进行了十多年的药物发现工作,但在全身给药后能显着降低 CNS Aβ 水平的脑渗透性 BACE1 抑制剂的鉴定仍然具有挑战性。在本报告中,我们描述了一系列源自亚氨基嘧啶酮支架的脑渗透 BACE1 抑制剂的基于结构的优化。将基于结构的设计与物理化学性质的控制相结合,最终发现了化合物16,当对大鼠口服给药时,该化合物有效地降低了皮质和脑脊液 Aβ40 的水平。
