Study on the mechanism of Qing'e pill in the treatment of postmenopausal osteoporosis based on systemic pharmacology and molecular docking

Objective To explore the molecular mechanism of Qing''e pill in the treatment of postmenopausal osteoporosis, and to explore the potential therapeutic target of Qing''e pill. Methods TCMSP and BATMAN-TCM database were used to screen the compounds of Qing''e pill. The potential targets were identified in the PharMapper database. The related targets of postmenopausal osteoporosis were searched through GeneCards, PubMed, and CTD database. David software was used to perform the GO enrichment and KEGG pathway enrichment analysis on the key targets of Qing''e pill acting on postmenopausal osteoporosis. The key targets were located with the BioGPS database, and the molecular docking analysis was carried out with iGEMDOCK software. Results There were 32 effective chemical components, corresponding to 100 targets, through the network pharmacology analysis of 4 traditional Chinese medicines in Qing''e pill. 150 biological processes, 28 cell components, and 38 molecular functions were found through the GO analysis. 36 signal pathways with significant target enrichment were found through the KEGG analysis. The targets were enriched in the lung, liver, heart, kidney, and ovary through the organ positioning analysis with the bBioGPS software. Through molecular docking analysis, it was found that the key target of CYP3A4 had a high binding degree with hirsutin_qt. Conclusion Qing''e pill has the multi-component and multi-target characteristics. It can play its pharmacological role in regulating multiple signal pathways, regulating multiple tissues and organs by participating in a variety of biological processes to interfere postmenopausal osteoporosis.
