The present study involves the integrated network pharmacology and phytoinformatics-based investigation of phytocompounds from against diabetes mellitus-linked Alzheimer's disease. It aims to investigate the mechanism of the phytocompounds in the amelioration of diabetes mellitus-linked Alzheimer's disease through network pharmacology, druglikeness and pharmacokinetics, molecular docking simulations, GO analysis, molecular dynamics simulations, and binding free energy analyses. A total of 14 predicted genes of the 26 orally bioactive compounds were identified. Among these 14 genes, GAPDH and AKT1 were the most significant. The network analysis revealed the AGE-RAGE signaling pathway to be a prominent pathway linked to GAPDH with 50.53% probability. Upon the molecular docking simulation with GAPDH, isoeugenol was found to possess the most significant binding affinity (-6.0 kcal/mol). The molecular dynamics simulation and binding free energy calculation results also predicted that isoeugenol forms a stable protein-ligand complex with GAPDH, where the phytocompound is predicted to chiefly use van der Waal's binding energy (-159.277 kj/mol). On the basis of these results, it can be concluded that isoeugenol from could be taken for further in vitro and in vivo analysis, targeting GAPDH inhibition for the amelioration of diabetes mellitus-linked Alzheimer's disease.
本研究涉及基于整合网络药理学和植物信息学的研究,探讨了 中的植物化合物对糖尿病相关阿尔茨海默病的作用机制。本研究旨在通过网络药理学、类药性和药代动力学、分子对接模拟、GO 分析、分子动力学模拟和结合自由能分析,研究 中植物化合物改善糖尿病相关阿尔茨海默病的机制。共鉴定出 种口服生物活性化合物的 14 个预测基因。在这 14 个基因中,GAPDH 和 AKT1 最为重要。网络分析显示,AGE-RAGE 信号通路与 GAPDH 的关联度最高,概率为 50.53%。通过与 GAPDH 的分子对接模拟,发现异丁香酚具有最强的结合亲和力(-6.0 kcal/mol)。分子动力学模拟和结合自由能计算结果也预测,异丁香酚与 GAPDH 形成稳定的蛋白-配体复合物,其中植物化合物主要利用范德华结合能(-159.277 kj/mol)。基于这些结果,可以得出结论, 中的异丁香酚可以进一步进行体外和体内分析,针对 GAPDH 抑制作用改善糖尿病相关阿尔茨海默病。
