  Effect on Acetylcholinesterase and Anti-oxidant Activity of Synthetic Chalcones having a Good Predicted Pharmacokinetic Profile

  摘要：

  背景：乙酰胆碱酯酶（AChE）是开发治疗阿尔茨海默病（AD）药物的重要靶点。本研究中，我们探讨了22种合成的查尔酮对AChE活性的影响。 目标：本工作的目的是合成并评估查尔酮对AChE活性的影响，以及其抗氧化活性并预测其药代动力学特征。 方法：通过克莱森-施密特缩合合成查尔酮，并采用Elmann比色法评估其对AChE的抑制作用。为了确定抗氧化活性，选择了DPPH自由基清除法。 结果：我们发现所有查尔酮均抑制该活性，IC50值范围为0.008至4.8 µM。我们选择了活性最强的化合物19，其IC50值为0.008 µM，进行动力学研究，结果表明其呈现竞争性抑制模式。分子对接模拟显示化合物19与AChE的活性位点之间有良好的相互作用。考虑到药代动力学参数的预测是选择潜在药物候选物的有用工具，我们的研究结果表明，大多数查尔酮，包括活性最强的，具有良好的药代动力学特征和血脑屏障渗透性。反应性氧种（ROS）在AD相关事件中的参与促使我们评估这些查尔酮作为自由基清除剂的潜力。 结论：我们发现化合物19是一种有效的AChE抑制剂，基于动力学研究，它作为竞争性抑制剂发挥作用。

  In the present study, a series of 46 chalcones were synthesised and evaluated for antiproliferative activities against the human TRAIL-resistant breast (MCF-7, MDA-MB-231), cervical (HeLa), ovarian (Caov-3), lung (A549), liver (HepG2), colorectal (HT-29), nasopharyngeal (CNE-1), erythromyeloblastoid (K-562) and T-Iymphoblastoid (CEM-SS) cancer cells. The chalcone 38 containing an amino (-NH2) group on ring A was the most potent and selective against cancer cells. The effects of the chalcone 38 on regulation of 43 apoptosis-related markers in HT-29 cells were determined. The results showed that 20 apoptotic markers (Bad, Bax, BcI-2, Bcl-w, Bid, Bim, CD40, Fas, HSP27, IGF-1, IGFBP-4, IGFBP-5, Livin, p21, Survivin, 5TNE-R2, TRAIL-R2, XIAP, caspase-3 and caspase-8) were either up regulated or down regulated.

  Background: Acetylcholinesterase (AChE) is an important target in the development of drug to treat Alzheimer's disease (AD). In this work, we investigated the effect of twenty-two synthesized chalcones on AChE activity. Objective: This work is aimed to synthesize and evaluate the effect of chalcones on the AChE activity, as well as anti-oxidant activity and predict their pharmacokinetic profile. Method: Chalcones were synthesized through a Claisen-Schmidt condensation and their inhibitory effect on the AChE was evaluated by the Elmann's colorimetric method. To determine the anti-oxidant activity the DPPH radical scavenging method was chosen. Results: We found that all chalcones inhibit this activity, with IC50 values ranging from 0.008 to 4.8 µM. We selected the most active compound 19 with an IC50 value of 0.008 µM for a kinetic study demonstrating a competitive inhibition mode. Molecular docking simulations showed a good interaction between 19 and the active site of AChE. Considering the prediction of pharmacokinetic parameters being a useful tool for selecting potential drug candidates, our study results suggest that the majority of chalcones, including the most active one, have a promising pharmacokinetic profile and blood-brain barrier permeability. The involvement of reactive oxygen species (ROS) in AD-related events has encouraged us to evaluate these chalcones as radical scavengers. Conclusion: We have found that compound 19 is a potent AChE inhibitor, and based on kinetic studies, it acts as a competitive inhibitor.
