Explore pharmacological mechanism of glycyrrhizin based on systems pharmacology / 中国中药杂志

ABSTRACT

To explore the pharmacological mechanism of glycyrrhizin with series methods of systems pharmacology, main diseases related to glycyrrhizin were obtained by text mining tool; and the target proteins of glycyrrhizin were obtained via the database of Polysearch and PubChem. Then, the target proteins interaction network of glycyrrhizin was built using the software called Cytoscape. Next, the protein groups related to glycyrrhizin were analyzed by using Gene Ontology (GO) tool, and the action pathway of its target proteins was analyzed by using enrichment method. Text mining results showed that the related diseases of glycyrrhizin included chronic hepatitis C, chronic hepatitis, hepatitis, HIV virus, liver cancer and so on. Gene ontology analysis indicated that glycyrrhizin played a role mainly through modification of proteins and chromatin. The signaling pathway enrichment results showed that the main action proteins of glycyrrhizin were related to MAPK signaling pathway, toll-like receptor signaling pathway, neurotrophic factor signaling pathway, cancer and apoptosis pathways. So we can conclude that glycyrrhizin may exert its biological functions primarily by regulating multiple pathways such as MAPK signaling pathway and Toll-like receptors signaling pathway. The pharmacological action of a drug can be rapidly and comprehensively analyzed by the ways of systems pharmacology.
