Based upon modeling results obtained using the crystal structure of huperzine A in complex with acetylcholinesterase (AChE), two novel analogues of this potent AChE inhibitor were designed with phenol or catechol rings replacing the pyridone ring. From the modeling studies, the catechol analogue appeared capable of replacing one of the crystallographic waters bridging huperzine with Tyr 130 and Glu
基于使用石杉碱甲晶体结构与乙酰胆碱酯酶(AChE)结合获得的建模结果,设计了该有效AChE抑制剂的两个新类似物,其中苯酚或邻苯二酚环取代了吡啶酮环。通过建模研究,发现邻苯二酚类似物能够用AChE的Tyr 130和Glu 199取代石杉碱桥接的结晶水。通过使用钯催化的双环化策略合成这些材料以及AChE抑制分析的结果进行了详细介绍。
