Cholinesterases (ChEs) play a vital role in the regulation of cholinergic transmission. The inhibition of ChEs is
considered to be involved in increasing acetylcholine level in the brain and thus has been implicated in the treatment of
Alzheimer’s disease. We have designed and synthesized a series of novel indole derivatives and screened them for inhibition
of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Most of the tested compounds exhibited inhibitory
activity against AChE and BChE. Among them 4f and 6e showed the highest AChE inhibitory activity with
IC50 91.21±0.06 and 68.52±0.04 µM, respectively. However compound 5a exhibited the highest inhibitory activity against
BChE (IC50 55.21±0.12 µM).
胆碱酯酶(ChEs)在调节胆碱能传递中扮演着至关重要的角色。抑制ChEs被认为能提高大脑中乙酰胆碱的水平,因此与治疗阿尔茨海默病有关。我们设计并合成了一系列新颖的吲哚衍生物,并对它们进行了乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的抑制筛选。大多数测试的化合物对AChE和BChE显示出抑制活性。其中,4f和6e对AChE表现出最高的抑制活性,IC50值分别为91.21±0.06和68.52±0.04 µM。然而,化合物5a对BChE表现出最高的抑制活性(IC50 55.21±0.12 µM)。
