  New semicarbazones as gorge-spanning ligands of acetylcholinesterase and potential new drugs against Alzheimer’s disease: Synthesis, molecular modeling, NMR, and biological evaluation

  摘要：

  Two new compounds (E)-2-(5,7-dibromo-3,3-dimethyl-3,4-dihydroacridin-1(2H)-ylidene)hydrazinecarbothiomide (3) and (E)-2-(5,7-dibromo-3,3-dimethyl-3,4-dhihydroacridin-1(2H)-ylidene) hydrazinecarboxamide (4) were synthesized and evaluated for their anticholinesterase activities. In vitro tests performed by NMR and Ellman's tests, pointed to a mixed kinetic mechanism for the inhibition of acetylcholinesterase (AChE). This result was corroborated through further docking and molecular dynamics studies, suggesting that the new compounds can work as gorge-spanning ligands by interacting with two different binding sites inside AChE. Also, in silico toxicity evaluation suggested that these new compounds can be less toxic than tacrine.

  A new mild enzymatic methodology for synthesizing quinoline derivatives by Friedländer condensation was developed. A series of quinoline derivatives were synthesized and characterized by 1H NMR, 13C-NMR, IR and MS. The probable enzymatic mechanism was proposed. It provides a novel method to prepare quinoline derivatives.Graphical Abstract

  is associated with the memory loss. In this work, a new guanylhydrazone was designed and synthesized as an AChE inhibitor. This new compound was compared to tacrine and other guanylhydrazones. All of them were studied by molecular docking and tested in vitro as AChE inhibitors by Ellman's test and Fig-NMR method. A high inhibition of AChE by the new compound was observed, showing that this compound has

  由于这是痴呆症的最常见类型，因此开发用于治疗阿尔茨海默氏病（AD）的药物非常重要。抑制乙酰胆碱酯酶（AChE）对于增加在患者中观察到的低水平的乙酰胆碱（ACh）神经递质很重要，这与记忆力丧失有关。在这项工作中，设计并合成了一种新的胍hydr作为AChE抑制剂。将该新化合物与他克林和其他胍基compared进行了比较。所有这些均通过分子对接研究，并通过Ellman试验和Fig-NMR法在体外作为AChE抑制剂进行了测试。观察到新化合物对AChE的高度抑制作用，表明该化合物具有治疗AD的巨大潜力。
