Abstract

The present study involved the targeted synthesis and characterization of novel indole amines with anti-acetylcholinesterase profiling. A series of proposed indole amines was virtually screened against human acetylcholinesterase. A few indole amines (23, 24, and 25) showing strong enzyme binding in the studies were synthesized in the laboratory and characterized using spectroscopic (IR, UV, NMR, single crystal XRD) and spectrometric (EIMS, HR-EIMS) methods. The indole amine 23 was crystallized from EtOH and analyzed with single crystal XRD. These ligands interacted with the PAS site in the enzyme, and their binding may disrupt the activity. The acetylcholinesterase inhibition studies revealed that the IC values for indole amines 25 and 24 (4.28 and 4.66 μM, respectively) were comparable to that of galantamine (4.15 μM) and may be studied further as cost-effective acetylcholinesterase inhibitors.

摘要

本研究涉及具有抗乙酰胆碱酯酶活性的新型吲哚胺的靶向合成与表征。针对人乙酰胆碱酯酶虚拟筛选了一系列拟议的吲哚胺。在研究中显示出强酶结合能力的几种吲哚胺(23、24和25)在实验室中合成,并使用光谱法(红外光谱、紫外光谱、核磁共振、单晶X射线衍射)和质谱法(电子轰击质谱、高分辨电子轰击质谱)进行表征。吲哚胺23从乙醇中结晶出来,并用单晶X射线衍射进行分析。这些配体与酶中的PAS位点相互作用,它们的结合可能会破坏酶的活性。乙酰胆碱酯酶抑制研究表明,吲哚胺25和24的IC值(分别为4.28和4.66 μM)与加兰他敏(4.15 μM)相当,可作为具有成本效益的乙酰胆碱酯酶抑制剂进一步研究。
