of pharmacological activities, including cholinesterase inhibition. The cholinesterase inhibitors provide symptomatic treatment for Alzheimer's disease; however, multitarget-directed ligands have the potential as disease-modifying therapeutics. Herein, we prepared a series of C9-substituted berberrubine derivatives intending to discover dual cholinesterase and beta-site amyloid-precursor protein cleaving
Berberrubine 是一种天然存在的异喹啉生物碱,是小檗碱的生物活性代谢物。小檗碱具有广泛的药理活性,包括抑制胆碱酯酶。胆碱酯酶抑制剂为阿尔茨海默病提供对症治疗;然而,多靶点定向配体具有作为疾病缓解疗法的潜力。在此,我们制备了一系列 C9 取代的小檗碱衍生物,旨在发现双重胆碱酯酶和 β 位淀粉样前体蛋白裂解酶 1 (BACE-1) 抑制剂。大多数合成的衍生物在亚微摩尔范围内具有平衡的双重抑制(AChE 和 BChE)活性,并对 BACE-1 具有适度的抑制作用。两种最活跃的酯衍生物,12a和11d, 显示 AChE、BChE 和 BACE-1 的抑制作用。3-甲氧基苯甲酰酯衍生物12a抑制电鳗乙酰胆碱酯酶 (EeAChE)、马血清丁酰胆碱酯酶 (eqBChE) 和人 hBACE-1,IC 50值分别为 0.5、4.3 和 11.9 μM,并且具有出色的 BBB 渗透性 ( P e =
