A new series of structurally rigid donepezil analogues was designed, synthesized and evaluated as potential multi-target-directed ligands (MTDLs) against neurodegenerative diseases. The investigated compounds 10–13 displayed dual AChE and BACE-1 inhibitory activities in comparison to donepezil, the FDA-approved drug. The hybrid compound 13 bearing 2-aminoquinoline scaffold exhibited potent AChE inhibition
设计,合成和评估了一系列新的结构刚性多奈哌齐类似物,作为对抗神经退行性疾病的潜在多靶标定向配体(MTDL)。所研究化合物10 - 13显示双乙酰胆碱酯酶和BACE-1的抑制活性相比,多奈哌齐,FDA批准的药物。带有2-氨基喹啉骨架的杂合化合物13表现出有效的AChE抑制作用(IC 50值为14.7 nM)和BACE-1抑制作用(IC 50值为13.1 nM)。分子模型研究被用来揭示13的潜在双重结合模式到AChE和BACE-1。在PAMPA-BBB分析中,进一步研究了所研究化合物对SH-SY5Y神经母细胞瘤细胞的生存能力及其穿越血脑屏障(BBB)的能力。
