Abstract

The present study aimed to explore the targets and mechanism of Mailuo Shutong Pills(MSP) in the treatment of ischemic stroke by network pharmacology, and verify the key targets through molecular docking and animal experiment, so as to provide a theoretical basis for the clinical application of MSP. The main chemical ingredients of MSP were obtained by searching against the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and relevant literature. The potential targets of the ingredients of MSP in treating ischemic stroke were obtained from SwissTargetPrediction and DisGeNET. Protein-protein interaction(PPI) network was analyzed in STRING and plotted in Cytoscape. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out with DAVID. Molecular docking was simulated to determine the binding activity of active ingredients to key targets in AutoDock Vina. The mouse model of ischemic stroke was established. The mice were classified into a sham group, a model group, and an MSP group. After the administration, cerebral infarction volume was detected by 2,3,5-triphenyltetrazoliumchloride(TTC) staining, and Western blot was performed to determine the levels of phosphatidylinositol 3-kinase(PI3 K), protein kinase B(AKT), nuclear factor-κB(NF-κB) and their phosphorylated proteins. A total of 222 ingredients of MSP were screened out, including beta-sitosterol, quercetin, licochalcone B, and lupiwighteone, which acted on 701 targets. Totally 1 079 targets associated with ischemic stroke were retrieved, among which 192 common targets were shared by MSP and ischemic stroke. The key targets included AKT1, phosphatidylinositol 3-kinase catalytic subunit alpha(PIK3 CA), phosphatidylinositol 3-kinase regulatory subunit 1(PIK3 R1), and nuclear factor-κB p65 subunit(RELA), which were mainly involved in PI3 K/AKT, tumor necrosis factor(TNF), and NF-κB signaling pathways. The results of molecular docking revealed that PI3 K, AKT1, and RELA had good binding ability to the active ingredients of MSP. The animal experiment results showed that compared with the model group, MSP decreased cerebral infarction volume, down-regulated the expression of p-NF-κB, and up-regulated the expression of p-PI3 K and p-AKT in mouse brain. In summary, the active ingredients in MSP may treat cerebral injury by activating PI3 K/AKT signaling pathway and inhibiting NF-κB signaling pathway.

摘要

本研究旨在通过网络药理学探索脉络舒通丸(MSP)治疗缺血性脑卒中的靶点及作用机制,并通过分子对接和动物实验验证关键靶点,为MSP的临床应用提供理论依据。通过在中药系统药理学数据库与分析平台(TCMSP)及相关文献中检索,获取MSP的主要化学成分。从SwissTargetPrediction和DisGeNET中获取MSP成分治疗缺血性脑卒中的潜在靶点。在STRING中分析蛋白质-蛋白质相互作用(PPI)网络,并在Cytoscape中绘制。使用DAVID进行基因本体(GO)注释和京都基因与基因组百科全书(KEGG)通路富集分析。在AutoDock Vina中模拟分子对接,以确定活性成分与关键靶点的结合活性。建立缺血性脑卒中小鼠模型。将小鼠分为假手术组、模型组和MSP组。给药后,通过2,3,5-三苯基氯化四氮唑(TTC)染色检测脑梗死体积,并进行蛋白质免疫印迹法检测磷脂酰肌醇3-激酶(PI3K)、蛋白激酶B(AKT)、核因子-κB(NF-κB)及其磷酸化蛋白的水平。共筛选出MSP的222种成分,包括β-谷甾醇、槲皮素、甘草查尔酮B和羽扇豆黄素,这些成分作用于701个靶点。共检索到1079个与缺血性脑卒中相关的靶点,其中MSP与缺血性脑卒中共有192个共同靶点。关键靶点包括AKT1、磷脂酰肌醇3-激酶催化亚基α(PIK3CA)、磷脂酰肌醇3-激酶调节亚基1(PIK3R1)和核因子-κB p65亚基(RELA),主要参与PI3K/AKT、肿瘤坏死因子(TNF)和NF-κB信号通路。分子对接结果显示,PI3K、AKT1和RELA与MSP的活性成分具有良好的结合能力。动物实验结果表明,与模型组相比,MSP可减小小鼠脑梗死体积,下调p-NF-κB的表达,上调小鼠脑中p-PI3K和p-AKT的表达。综上所述,MSP中的活性成分可能通过激活PI3K/AKT信号通路和抑制NF-κB信号通路来治疗脑损伤。
