series of poly-functionalized tacrine-derived compounds namely 5-amino-2-phenyl-4H-pyrano[2,3-b]quinoline-3-carboxylates were designed and synthesized as cholinesterases inhibitors. The in vitro inhibition assay against AChE and BuChE demonstrated that most of compounds had potent AChE inhibitory with reserving potential of BuChE inhibition. Among them, compound 6i bearing a 4-(3-bromophenyl) moiety showed
设计并合成了一系列多官能化他克林衍生的化合物,即5-氨基-2-苯基-4 H-吡喃并[2,3 - b ]喹啉-3-羧酸盐,它们是胆碱酯酶抑制剂。体外对AChE和BuChE的抑制试验表明,大多数化合物具有有效的AChE抑制作用,并保留BuChE抑制作用。其中,带有4-(3-溴苯基)部分的化合物6i对AChE / BuChE表现出最强的活性(IC 50值分别为0.069和1.35μM)。6i的抗AChE活性是他克林的5倍。SAR研究表明,邻位或间位的氯/溴取代基 4-苯环的位置可以提高抗胆碱酯酶的活性。
