Abstract:

BACKGROUND: The treatment of osteoporosis is a major problem that plagues the medical field. In particular, the development and application of new drugs have always been the focus of modern pharmacology and regenerative medicine. As a common medicinal herb, Inulae flos has not been studied for its value in the prevention and treatment of osteoporosis. The relationship between the two is analyzed from the network pharmacology level to provide a certain theoretical basis for new drug development and disease treatment. 

OBJECTIVE: To explore the application prospects of Inulae flos in the treatment of osteoporosis by means of network pharmacology. 

METHODS: The active ingredients of Inulae flos were screened by TCMSP database. The targets of active ingredients were predicted from TCMSP and Swiss Target Prediction database, and the targets of osteoporosis were predicted by GeneCards database and DrugBank database. Protein-protein interaction network analysis was conducted with String database. Cytoscape software was used to construct a protein-protein interaction network diagram and a drugcomponent-target-disease network diagram. David database was used for enrichment analysis. Molecular docking prediction was completed using autodock vina software. 

RESULTS AND CONCLUSION: There were 19 effective pharmaceutical active ingredients of Inulae flos and 180 potential targets for osteoporosis treatment, such as AKT1, TP53, VEGFA. Quercetin, luteolin, and kaempferol are considered to be the key effective ingredients for the treatment of osteoporosis by Inulae flos. The results of enrichment analysis showed that the therapeutic effect of Inulae flos on osteoporosis may be related to cell proliferation and apoptosis, aging, hormone levels and hypoxic stress and other life processes, and may be directly or indirectly associated with mediating signaling pathways such as FOXO, PI3K-Akt, and hypoxia inducible factor 1. The therapeutic effect of Inulae flos on osteoporosis needs to be verified by more basic experiments. Our research provides new ideas and new methods for follow-up experiments.
