摘要: 基于网络药理学方法探究核桃(Juglans regia L.)防治老年痴呆(Alzheimer's disease,AD)的作用机制,通过TCMSP数据库和文献挖掘获得核桃的活性成分及相应潜在靶点;使用OMIM等数据库进行AD相关基因预测和筛选;采用Cytoscape 3.7.2软件构建“药物-活性成分-疾病-靶点”网络以形成核桃防治AD的成分及靶点相互作用关系,并进行GO功能和KEGG通路富集分析。结果表明,筛选获得29种核桃活性成分,其中17种成分具有AD相关靶点159个,PTGS1/2、RXRA、RELA、MAOB和NOS3可能是AD的关键靶点,主要信号通路为AGE-RAGE信号通路、动脉粥样硬化、PI3K-Akt信号通路、IL-17信号通路和HIF-1信号通路。核桃通过多成分、多靶点、多途径防治AD,其中作用靶点最多的成分为槲皮素、油酸、鞣花酸;受最多化合物作用的靶点为前列腺素过氧化物合成酶、视黄酸受体、转录因子p65、单胺氧化酶和一氧化氮合酶。

Abstract: The mechanism of walnut(Juglans regia L.) in prevention and treatment of Alzheimer's disease(AD) was explored based on network pharmacology. The active components and potential targets of walnut were obtained by TCMSP database and literature mining. The prediction and screening of AD related genes were performed using databases such as OMIM; Cytoscape 3.7.2 software was used to construct a “drug-active component-disease-target” network to formation of the interactive relationship of walnuts toprevent AD components and target, and analysis of GO function and KEGG pathway enrichment. The results showed that 29 walnut active ingredients were screened, 17 of which had 159 AD-related targets. PTGS1/2, RXRA, RELA, MAOB and NOS3 may be the key targets of AD. The main signal pathways were AGE-RAGE signaling pathway, atherosclerosis, PI3K-Akt signaling pathway, IL-17 signaling pathway and HIF-1 signaling pathway. Walnut can prevent and control AD through multi-component, multi-target, and multi-pathway. The components with the most targets are quercetin, oleic acid, and ellagic acid; the targets affected by the most compounds are prostaglandin G/H synthase, retinoic acid receptor RXR-alpha, transcription factor p65, amine oxidase [flavin-containing] B and nitric oxide synthase.

Key words: walnut(Juglans regia L.), Alzheimer's disease, internet pharmacology, mechanism of action
