Mechanism of Acanthopanax senticosus injection in the treatment of ischemic stroke based on UPLC-Q-TOF-MS and network pharmacology

目的运用超高效液相色谱-飞行时间质谱联用技术(UPLC-Q/TOF-MS)整合网络药理学研究刺五加注射液治疗缺血性脑卒中的物质基础及潜在作用机制。方法利用UPLC-Q/TOF-MS鉴定刺五加注射液的化学成分,通过Swiss Target Prediction、GeneCards和OMIM数据库预测刺五加注射液治疗缺血性脑卒中的潜在作用靶点,利用String数据库和Cytoscape软件构建蛋白质-蛋白质相互作用网络,通过Omicshare平台对治疗靶点进行GO和KEGG富集分析,运用Autodock软件进行分子对接。结果分析鉴定了刺五加注射液中53种成分,并以此为基础得到刺五加注射液治疗缺血性脑卒中的相关靶点189个及10个核心靶点,反向筛选发现刺五加注射液中的25个成分可能是治疗缺血性脑卒中的主要有效成分;KEGG富集结果显示,刺五加注射液可能主要通过调节PI3K-Akt信号通路来治疗缺血性脑卒中。结论刺五加注射液治疗缺血性脑卒中的作用机制可能与抑制炎症反应、抗氧化应激、促进血管新生和保护神经细胞等作用有关。

Objective To analyse the material basis and potential mechanism of Acanthopanax senticosus injection(ASI)in the treatment of ischemic stroke by combining UPLC-Q/TOF-MS and network pharmacology.Methods The chemical composition of ASI was identified by UPLC-Q/TOF-MS.The Swiss Target Prediction,GeneCards and OMIM databases were used to predict the potential targets for the action of ASI in the treatment of ischemic stroke.The String database and Cytoscape software were used to construct protein interaction network maps,and the Omicshare platform was used to perform gene ontology(GO)and KEGG enrichment analysis.The DockThor platform was used for molecular docking.Results The analysis of 53 components in ASI was firmly established and used as a basis to obtain 189 related targets of ASI for the treatment of ischemic stroke.Reverse screening showed that 25 components in ASI may be important active components in the treatment of ischemic stroke.Functional enrichment studies found that ASI may mainly regulate PI3K-Akt signaling pathway to treat ischemic stroke.Conclusion This study preliminarily predicted the mechanism of ASI in the treatment of ischemic stroke may be related to inhibition of inflammation,antioxidant stress,promotion of angiogenesis and protection of nerve cells.
