Molecular Mechanism of Nardostachyos Radix et Rhizoma-Agrimoniae Herba in Treatment of Arrhythmia Based on Network Pharmacology
甘松-仙鹤草药对中槲皮素、山柰酚、金合欢素等9种活性成分治疗PVCs的靶点主要涉及肿瘤坏死因子(TNF),丝裂原活化蛋白激酶1(MAPK1),蛋白激酶B1(Akt1)等。其潜在靶点主要富集在癌症通路(pathways in cancer),高级糖基化终末产物/高级糖基化终末产物受体信号通路(AGE/RAGE signaling pathway in diabetic complications)等26条相关信号通路。分子对接结果显示该药对大部分活性成分(92.59%)与主要靶点蛋白TNF,MAPK1,Akt1的结合活性较好。
To explore the material basis and mechanism of Nardostachyos Radix et Rhizoma (NRER)-Agrimoniae Herba (AH), the herbal pair effective in regulating the liver, invigorating Qi, and calming palpitations, in the treatment of premature ventricular contractions (PVCs) by network pharmacology and molecular docking.
Method
2
The chemical components and targets of NRER and AH were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) combined with relevant literature. GeneCards,Online Mendelian Inheritance in Man(OMIM),and DrugBank were used to predict the potential targets against PVCs. STRING platform was used for protein-protein interaction (PPI) analysis. Metascape platform was used for Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. Cytoscape 3.8.0 was used to construct the NRER-AH component-potential target-signaling pathway network. The main target proteins underwent molecular docking to the active components of NRER-AH by AutoDock 4.2.6.
Result
2
The targets of nine active components in NRER-AH (such as quercetin,kaempferol,and acacetin) against PVCs mainly involved tumor necrosis factor (TNF),mitogen-activated protein kinase 1(MAPK1),and protein kinase B1(Akt1). The potential targets were mainly enriched in 26 signaling pathways,such as pathways in cancer and the advanced glycosylation end product (AGE)-receptor of advanced glycosylation end product(RAGE) signaling pathway. The results of molecular docking showed that the majority of the active components (92.59%) of NRER-AH had good binding activities with the main target proteins TNF,MAPK1,and Akt1.
Conclusion
2
The active components of NRER-AH can regulate cardiac ion channels,resist inflammation, and combat oxidative stress to treat PVCs through multi-target and multi-pathway interventions. They can also improve symptoms related to depression and anxiety by inhibiting monoamine oxidase activity and protecting nerves from damage. This study is expected to provide research ideas and the theoretical basis for further exploring the material basis and mechanism of NRER-AH in the treatment of PVCs.
