A series of aloe-emodin derivatives were designed, synthesized and evaluated as acetylcholinesterase inhibitors. Most of the new prepared compounds showed remarkable acetylcholinesterase inhibitory activities. Among them, the compound 1-((4,5-dihydroxy-9,10-dioxo-9,10-dihydroanthracen-2-yl) methyl) pyridin-1-ium chloride (C3) which has a pyridinium substituent possessed the best inhibitory activity
设计,合成和评估了一系列芦荟大黄素衍生物,作为乙酰胆碱酯酶抑制剂。大多数新制备的化合物显示出显着的乙酰胆碱酯酶抑制活性。其中,具有吡啶鎓取代基的化合物1-((4,5-二羟基-9,10-二氧杂-9,10-二氢蒽-2-基)甲基)吡啶-1-氯(C3)具有最好的乙酰胆碱酯酶的抑制活性(IC 50 = 0.09μM)。用AUTODOCK进行的对接研究表明C3可以与乙酰胆碱酯酶的催化活性位点(CAS)和外围阴离子位点(PAS)相互作用。
