Abstract: Objective To analyze the molecular mechanism of Prunella vulgaris in the treatment of thyroid cancer using network pharmacology combined with molecular docking technology. Methods TCMSP database was used to predict the main active components of Prunella vulgaris, and TCMSP and PubChem database were used to obtain the corresponding targets of all active components. Thyroid targets for the treatment of thyroid cancer were collected through GeneCards and OMIM database. The interaction information between proteins was obtained by using STRING database, and the topology analysis and visualization were carried out by using R language. GO and KEGG pathway analysis was conducted on the intersection targets of drugs and diseases obtained above using the clusterProfiler. Cytoscape 3.7.2 was used to construct the active component-target-disease network, and the core compounds were obtained through topological analysis. The core targets and compounds were verified by molecular docking. Results Quercetin, luteolin, kaempferol and sitosterol may be the core components in the treatment of thyroid cancer, while AKTI, VEGFA, CASP3, MYC, JUN, MAPK8, IL6, EGFR, MAPK1 and EGF may be the important therapeutic targets. Conclusion The treatment of thyroid carcinoma by Prunella vulgaris shows the characteristics of multiple components, multiple targets and multiple pathways, which provides a theoretical basis for the screening and further study of the effective components of Prunella vulgaris.
