for their inhibitory activity against the enzymes acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and monoamine oxidases A and B (MAO‐A/B). The results of in vitro studies revealed IC50 values in the micromolar range, with the majority of the compounds showing selectivity for the MAO‐B isoform. N‐[2‐Oxo‐1‐(prop‐2‐ynyl)indolin‐3‐ylidene]benzo[d][1,3]dioxole‐5‐carbohydrazide (3) was identified
合成了一组具有可变的isatin部分的胡椒基,并评估了它们对乙酰胆碱酯酶(AChE),丁酰胆碱酯酶(BChE)以及单胺氧化酶A和B(MAO-A / B)的抑制活性。体外研究结果表明,IC 50值在微摩尔范围内,大多数化合物对MAO-B同工型具有选择性。N- [2-氧代-1-(丙-2-炔基)吲哚-3-基]苯并[ d ] [1,3]二恶唑-5-碳酰肼(3)被鉴定为铅AChE抑制剂,IC 50 = 0.052±0.006μ米。N -[(3 E)-5-氯-2-氧-2,3-二氢-1 H-吲哚-3-亚基] -2- ħ -1,3-苯并二氧杂环戊-5-碳酰肼(2)为引MAO-B抑制剂,IC 50 = 0.034±0.007μ米,并表现出对MAO-B的50倍更大的选择性通过MAO-A。动力学研究表明,化合物2和3分别显示出对AChE和MAO-B的竞争性和可逆性抑制。分子对接研究揭示了在所研究的酶的活性位点口
