Abstract: Objective To analyze the mechanism of Xuduan promoting fracture healing by network pharmacology and molecular docking technology. Methods The active components of Xuduan were acquired through traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) database by setting the oral drug bioavailability (OB)≥30% and drug like index (DL)≥0.18 as screening criteria, and the target genes of the active components were obtained. The bone fracture related genes were obtained by searching TTD, OMIM, Genecards, Drugbank and PharmGkb databases. The main target genes were obtained by matching the target genes of Xuduan active components with fracture related genes. The results were visualized by EVenn. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of main target genes were analyzed by DAVID database and protein interaction network was constructed by STRING databases. Key genes in main target genes were obtained by degree and betweenness algorithms. Finally, Pymol and Autoduck softwares were used for molecular docking and calculating the minimum binding energy, binding site and fixed active pocket. Results Totally 8 active components and 63 target genes of Xuduan were screened by TCMSP database, and 53 target genes were obtained by deleting repeated target genes. Totally 5 115 genes related to bone fracture were obtained from TTD, OMIM, GeneCards, DrugBank and PharmGkb databases. Totally 34 main target genes were obtained by matching and intersection analysis. The 34 target genes were enriched in 76 biological processes, 20 cellular components and 20 molecular functions through DAVID database analysis. The protein interaction network was constructed by STRING database. A total of 34 genes and 79 connections were included. The average degree parameter was 4.65. Xuduan promoting bone healing key genes were PTGS2, HSP90AA1 and MAPK14 by calculating degree and betweenness in Cytoscape software. The active components with optimal bioavailability, as (E,E)-3,5-Di-O-caffeoylquinic acid, Gentisin and Sylvestroside Ⅲ_qt could bind with the key genes PTGS2, HSP90AA1 and MAPK14 at a less than 0 energy. The binding sites were obtained by Pymol and Autoduck software. Conclusion Through network pharmacology and molecular docking technology, the possible potential mechanism of Xuduan promoting fracture healing were clarified, and its effective components and key genes were predicted.
