[Abstract]
Objective To screen the main active ingredients and molecular mechanism of Dianxianning Tablets through network pharmacology and molecular docking methods. Method TCMSP and Herb database were used to screen the main active ingredients and targets of Dianxianning Tablets. GeneCard, OMIM, and DisGent were selected as therapeutic targets for epilepsy. Construct the "drug active ingredient-target" network using Cytoscape 3.8.2 software. The drug-intersection gene was uploaded to the interaction database String to construct the PPI network. The drug-disease intersection genes were uploaded to Bioconductor, the bioinformatics software was used to GO and KEGG pathways of biological processes, and the key targets and components were validated by molecular docking. Genetic Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed, and key targets and components were validated by molecular docking. Results A total of 70 active ingredients and 308 targets were selected for Dianxianning Tablets, in which the first 9 active ingredients of the degree were hirsutine, kaempferol, penniclavin, and β-sitosterol, respectively. There are 10 core targets, including RELA, JUN, MAPK1, STAT3, TP53, Akt1, ESR1, TNF, MAPK8. A total of 5 195 GO entries were screened, and 259 pathways related to drug treatment of epilepsy were enriched. The results of molecular docking showed that the core target was well bound to the active ingredient. Conclusion This study provided a new understanding of DianxianNing Tables' benefitting effect for treatment of epilepsy based on network pharmacology and molecular docking technology, which jointly elucidated the relationship between the active ingredients of drugs and epilepsy, and provided a scientific basis for clinical drug treatment.
