目的:基于网络药理学探讨生脉散治疗病毒性心肌炎(VMC)的主要活性成分及其潜在作用机制。方法:运用本草组鉴数据库(HERB)初步获取生脉散的活性成分,结合SwissADME和SwissTargetPrediction平台筛选其中的主要活性成分,并预测其靶点。通过GeneCards及DisGeNET数据库筛选VMC相关靶点。取药物靶点与疾病靶点交集,获得生脉散治疗VMC的潜在治疗靶点。运用STRING数据库构建潜在治疗靶点蛋白质-蛋白质相互作用(PPI)网络图,并通过Cytoscape 3.7.1软件挖掘PPI网络中的核心靶点。运用Cytoscape 3.7.1软件构建“中药-活性成分-靶点-疾病”相互作用网络图,将潜在治疗靶点导入DAVID 6.8数据库进行基因本体(GO)功能及京都基因与基因组百科全书(KEGG)通路富集分析。结果:本研究共筛选出生脉散治疗VMC的有效活性成分151个,涉及55个潜在治疗靶点,405个生物过程,36个细胞组分,55个分子功能和147条代谢通路。结论:生脉散可通过调控细胞因子、蛋白激酶、天然免疫基因等多靶点、多途径干预VMC的进程,为其临床应用提供了理论基础。 相似文献

Antiviral active peptide from oyster 总被引:1,自引:0,他引:1
An active peptide against herpes virus was isolated from the enzymic hydrolysate of oyster (Crassostrea gigas) and purified with the definite direction hydrolysis technique in the order of alcalase and bromelin. The hydrolysate was fractioned into four ranges of molecular weight (〉10 kDa, 10-5 kDa, 5-1 kDa and 〈1 kDa) using ultrafiltration membranes and dialysis. The fraction of 10-5 kDa was purified using consecutive chromatographic methods including DEAE Sephadex A-25 column, Sephadex G-25 column, and high performance liquid chromatogram (HPLC) by activity-guided isolation. The antiviral effect of the obtained peptide on herpetic virus was investigated in Vero cells by observing cytopathic effect (CPE). The result shows that the peptide has high inhibitory activity on herpetic virus. 相似文献
