Abstract:
Hypertension is a kind of chronic cardiovascular system disease caused by a series of factors and carriers dysfunction, which belongs to the category of Tibetan medicine "Chalong disease", and has a high rate of disability and mortality. Zuomua Decoction is a classical Tibetan medicine for Chalong disease, but its mechanism is not clear. Therefore, in this paper we explored the multi-components, multi-targets and multi-channels mechanism of Zuomua Decoction in the treatment of hypertension based on network pharmacology and molecular docking technology. First of all, the chemical components of Zuomua Decoction were obtained in the retrieval of traditional Chinese medicine systems pharmacology database(TCMSP), China National Knowledge Infrastructure(CNKI) and Wanfang database. The potential targets of Zuomua Decoction were predicted by BATMAN-TCM database, and the targets of hypertension were obtained by using DisGeNET database. The intersection of these two targets set was taken to obtain the potential targets of Zuomua Decoction in the treatment of hypertension, and then the chemical compositions-targets network was constructed. Secondly, the intersection targets were imported into STRING database to obtain the interaction relationship of intersection targets, and the protein interaction network of Zuomua Decoction in the treatment of hypertension was constructed in Cytoscape. Topological, GO, and KEGG enrichment analysis were used to construct the key targets-signal pathways-biological processes network diagram and explore the mechanism of Zuomua Decoction in the treatment of hypertension. Finally, the key targets were selected to construct the pharmacodynamic identification models to verify the effect mode of Zomua Decoction in treating hypertension. The results showed that there were 61 chemical components and 90 potential targets in the compounds-targets network. We obtained 21 key targets, 154 signal pathways, and 382 biological processes in topological, GO, and KEGG enrichment analysis of the protein interaction network, and in the comprehensive analysis, it was found that Zuomua Decoction could reduce blood pressure by regulating renin angiotension aldosterone system, balancing the concentration of intracellular calcium and sodium ions and regulating vasoconstriction and relaxation. ACE, AGTR1, and ADRB2 were used as the carriers for molecular docking study on the components of Zuoma Decoction, and the results showed that the chemical components of Zuomua Decoction had a good binding activity with key targets. The purpose of this study is to provide ideas for the in-depth study of Zuoma Decoction in the treatment of hypertension, and provide scientific basis for its clinical rational application.
