of novel berberine derivatives were designed, synthesized, and biologically evaluated as inhibitors of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among these derivatives, compound 48a, berberine linked with 3-methylpyridinium by a 2-carbon spacer, was found to be a potent inhibitor of AChE, with an IC50 value of 0.048 μM and compound 40c, berberine linked with 2-thionaphthol
设计,合成了一系列新颖的小ber碱衍生物,并对其进行了生物学评估,以作为乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)的抑制剂。在这些衍生物中,发现化合物48a(通过2碳间隔基与3-甲基吡啶鎓连接的小ber碱)是有效的AChE抑制剂,IC 50值为0.048μM,化合物40c(通过小ber碱通过2-碳硫醇连接2-硫酚)4-碳间隔基,作为BuChE最有效的抑制剂,IC 50值为0.078μM。AChE-抑制剂复合物的动力学研究和分子建模模拟表明,这些小碱衍生物存在混合竞争结合模式。
