Acetylcholinesterase inhibitors are currently of high interest due to the many reasons. Among them, Alzheimers disease drugs are of great interest. In this study, eleven monoquaternary pyridinium salts substituted by different groups (electron donors and electron acceptors) in position four were prepared. Then, their anticholinesterase activity was tested. As observed, their IC50s ranged from 33 μM to 3981 μM. Moreover, probability of blood-brain barrier penetration was predicted.
当前,乙酰胆碱酯酶抑制剂受到高度关注,原因有很多。其中,阿尔茨海默病药物尤为引人关注。在这项研究中,制备了十一种在第四位由不同基团(电子供体和电子受体)取代的单季铵吡啶盐。随后,测试了它们的抗胆碱酯酶活性。观察到它们的IC50范围从33 μM到3981 μM。此外,还预测了它们穿透血脑屏障的概率。
