Abstract

Neuroinflammation plays a pivotal role in the development and progression of neurodegenerative diseases, with a complex interplay between immune responses and brain activity. Understanding this interaction is crucial for identifying therapeutic targets and developing effective treatments. This study aimed to explore the neuroprotective properties of flavonoid compounds from Spondias mombin via the modulation of neuroinflammatory pathway using a comprehensive in-silico approach, including network pharmacology, molecular docking, and dynamic simulations. Active flavonoid ingredients from S. mombin were identified, and their potential protein targets were predicted through Network Pharmacology. Molecular docking was conducted to determine the binding affinities of these compounds against targets obtained from network pharmacology, prioritizing docking scores ≥ - 8.0 kcal/mol. Molecular dynamic simulations (MDS) assessed the stability and interaction profiles of these ligand-protein complexes. The docking study highlighted ≥ - 8.0 kcal/mol for the ligands (catechin and epicatechin) against FYN kinase as a significant target. However, these compounds failed the blood-brain barrier (BBB) permeability test. MDS confirmed the stability of catechin and the reference ligand at the FYN kinase active site, with notable interactions involving hydrogen bonds, hydrophobic contacts, and water bridges. GLU54 emerged as a key residue in the catechin-FYN complex stability due to its prolonged hydrogen bond interaction. The findings underscore the potential of S. mombin flavonoids as therapeutic agents against neuroinflammation, though optimization and nanotechnology-based delivery methods are suggested to enhance drug efficacy and overcome BBB limitations.

通过网络药理学和分子动力学模拟,报告精选的 spondias mombin 黄酮类化合物的抗神经炎症潜力。
神经炎症在神经退行性疾病的发生和发展过程中起着举足轻重的作用,免疫反应和大脑活动之间存在着复杂的相互作用。了解这种相互作用对于确定治疗靶点和开发有效的治疗方法至关重要。本研究旨在通过网络药理学、分子对接和动态模拟等综合的硅学方法,探索Spondias mombin中的黄酮类化合物通过调节神经炎症通路而具有的神经保护特性。通过网络药理学方法鉴定了Spondias mombin中的活性类黄酮成分,并预测了其潜在的蛋白质靶点。通过分子对接确定了这些化合物与网络药理学预测的靶点的结合亲和力,优先考虑对接得分≥ - 8.0 kcal/mol的化合物。分子动态模拟(MDS)评估了这些配体-蛋白质复合物的稳定性和相互作用概况。对接研究强调,配体(儿茶素和表儿茶素)对 FYN 激酶的作用靶点≥ - 8.0 kcal/mol。然而,这些化合物未能通过血脑屏障(BBB)渗透性测试。MDS 证实了儿茶素和参考配体在 FYN 激酶活性位点的稳定性,其显著的相互作用包括氢键、疏水接触和水桥。GLU54 是儿茶素-FYN 复合物稳定性的关键残基,因为它具有长时间的氢键相互作用。研究结果强调了S. mombin黄酮类化合物作为神经炎症治疗药物的潜力,不过建议采用优化和基于纳米技术的给药方法来提高药效和克服BBB的限制:
