A series of benzofuran-2-carboxamide-N-benzyl pyridinium halide derivatives (6a-o) are synthesized as new cholinesterase inhibitors. The synthetic pathway involves the reaction of salicylaldehyde derivatives and ethyl bromoacetate, followed by hydrolysis and amidation with 3- and 4-picolyl amine. Subsequently, N-((pyridin-4-yl) methyl) benzofuran-2-carboxamide and substituted N-((pyridin-3-yl) methyl)
合成了一系列苯并呋喃-2-羧酰胺-N-苄基吡啶鎓卤化物衍生物(6a-o)作为新型胆碱酯酶抑制剂。合成途径涉及水杨醛衍生物与溴乙酸乙酯的反应,然后水解并用3-和4-吡啶甲基胺进行酰胺化。随后,N -((吡啶-4-基)甲基)苯并呋喃-2-甲酰胺和取代的N -((吡啶-3-基)甲基)苯并呋喃-2-甲酰胺与苄基卤反应,得到目标化合物(6a-o )。所有衍生物的化学结构通过光谱法确认。研究表明,某些合成的化合物是有效的丁酰胆碱酯酶抑制剂,IC 50值在0.054–2.7 µM的范围内。此外,在6h和6k时观察到了对Aβ自聚集的良好抑制作用(在100 µM时分别为33.1%和46.4%)。
