An efficient and promising method of treating complex neurodegenerative diseases like Alzheimer’s disease (AD) is the multitarget-directed approach. Here in this work, a series of quinazoline derivatives (AV-1 to AV-21) were rationally designed, synthesized, and biologically evaluated as multitargeted directed ligands against human cholinesterase (hChE) and human β-secretase (hBACE-1) that exhibit
治疗阿尔茨海默病(AD)等复杂神经退行性疾病的一种有效且有前景的方法是多靶点定向方法。在这项工作中,一系列喹唑啉衍生物( AV-1至AV-21 )被合理设计、合成并进行生物学评估,作为针对人胆碱酯酶(hChE)和人β-分泌酶(hBACE-1)的多靶点定向配体,其表现出中度至良好的抑制作用。该系列的化合物AV-1 、 AV-2和AV-3对这些靶点表现出平衡且显着的抑制作用。通过 PAMPA-BBB 测定,这些化合物还表现出优异的血脑屏障渗透性。化合物AV-2显着取代乙酰胆碱酯酶外周阴离子位点 (AChE-PAS) 的碘化丙啶 (PI),并且发现在最大测试浓度 (80 μM) 下对分化的 SH-SY5Y 细胞系无神经毒性。在硫黄素 T 测定中,化合物AV-2还可以阻止 AChE 和自身诱导的 Aβ 聚集。此外,在体内行为 Y 迷宫和莫里斯水迷宫研究中,化合物AV-2分别显着改善东莨菪碱和 Aβ
