Mechanism of Erzhiwan in treating osteoporosis based on molecular docking technology and molecular dynamics...

This experiment was a network pharmacology research based on the theoretical system of traditional Chinese medicine. TCMSP database, PubChem database, RCSB database, and SwissTargetPrediction database were used to study the effective chemical constituents of Ligustri lucidi Fructus and Ecliptae Herba in Erzhiwan, a traditional prescription for nourishing the liver and kidney. Then Genecards database, OMIM database, OMIM Gene Map, and Metascape database were used to study the therapeutic targets of osteoporosis. At last, Cytoscape 3.6.0 software, its built-in Bisogenet and CytoNCA, AutoDockTools-1.5.6 software, PYMOL-2.2.0 software, and Gromacs software, by drawing the relationship diagram between chemical components and disease targets, PPI network of disease, semi-flexible molecular docking technology, evaluation and analysis of enrichment pathway, and molecular dynamics simulation, were used to study the therapeutic mechanism of Erzhiwan on osteoporosis. It is found that the intervention and regulation of Erzhiwan on osteoporosis were mainly realized through multiple targets of active ingredients and multiple pathways, which provided support for the continued development of Erzhiwan.
