A novel series of coumarin derivatives linked to benzyl pyridinium group were synthesized and biologically evaluated as inhibitors of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The enzyme inhibitory activity of synthesized compounds was measured using colorimetric Ellman’s method. It was revealed that compounds 3e, 3h, 3l, 3r and 3s have shown higher activity compared with
合成了一系列与苄基吡啶鎓基团连接的香豆素衍生物,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。合成的化合物的酶抑制活性使用比色Ellman法测量。揭示了与盐酸多奈哌齐作为标准药物相比,化合物3e,3h,3l,3r和3s显示出更高的活性。这些系列中的大多数化合物具有纳摩尔范围的IC 50,其中化合物3r(IC 50 = 0.11 nM)是对抗乙酰胆碱酯酶最有活性的化合物。
