摘 要 目的:探讨葶苈子潜在的药理作用机制,为其进一步开发利用和临床应用提供参考。方法:利用中药系统药理学分析平
台数据库和STRING数据库筛选并确认葶苈子的有效成分和相关靶标蛋白;运用Cytoscape 3.7.0软件构建葶苈子有效化合物-靶
标蛋白可视化网络,并进行网络拓扑学分析;借助STRING数据库和Cytoscape 3.7.0软件构建并分析葶苈子靶标蛋白-蛋白相互作
用(PPI)网络;通过DAVID生物信息学资源数据库对靶标蛋白进行KEGG通路富集分析。结果:共筛选获得葶苈子有效化合物9
个,包括槲皮素、山柰酚、β-谷甾醇等;获得靶标蛋白174个,主要包括人前列腺素内源性过氧化物合酶2(PTGS2)、核受体共激活
因子2、孕酮受体等,其中转录因子AP-1(JUN)、丝裂原活化蛋白激酶1(MAPK1)是PPI网络中的核心蛋白。KEGG富集通路包括
磷脂酰肌醇3-激酶/蛋白激酶B(PI3K/Akt)信号通路、肿瘤坏死因子α(TNF-α)信号通路、缺氧诱导因子1信号通路、Toll样受体信
号通路、甲状腺激素信号通路等。结论:葶苈子中的槲皮素、山柰酚、β-谷甾醇等有效化合物可能通过PI3K/Akt信号通路、TNF-α
信号通路等作用于PTGS2、JUN、MAPK1等靶标蛋白,进而发挥泻肺平喘、利水消肿的功效。

ABSTRACT OBJECTIVE:To investigate the potential pharmacological mechanism of the seed of Draba nemorosa,and to
provide reference for further development,utilization and clinical application. METHODS:Effective components and related target
proteins of D. nemorosa were screened and identified by using TCMSP and STRING database. Cytoscape 3.7.0 software was used
to construct a visual network of effective components and target proteins for the seed of D. nemorosa,and the network topology
analysis was performed. The targeting protein-protein interaction(PPI)network was constructed and analyzed by STRING database
and Cytoscape 3.7.0 software. KEGG pathway enrichment of target proteins was analyzed by DAVID bioinformatics resource
database. RESULTS:A total of 9 effective components were screened from the seed of D. nemorosa,including quercetin,
kaempferol,β-sitosterol,etc. Totally 174 target proteins were obtained,mainly including PTGS2,NCOA2,PGR,etc. Among
them,JUN and MAPK1 were core proteins in PPI network. KEGG enrichment pathway included PI3K/Akt signaling pathway,
TNF-α signaling pathway,HIF-1 signaling pathway,Toll-like receptor signaling pathway and thyroid hormone signal pathway,etc.
CONCLUSIONS:Effective components from the seed of D. nemorosa such as quercetin,kaempferol and β-sitosterol may act on
PTGS2,JUN and MAPK1 target proteins through PI3K-Akt signaling pathway and TNF-α signaling pathway,thus exert the effects
of purging lung,relieving asthma,promoting edema and reducing edema.
