Network Pharmacology and Molecular Docking to Explore the Mechanism of Action of Danxiong Huoxue Tablets for the Prevention and Treatment of Heterotopic Ossification

Background: Danxiong Huoxue tablets have been used clinically to prevent and treat Heterotopic Ossification (HO) after total hip arthroplasty, but its therapeutic mechanism is not clear. Objectives: This study investigated the potential mechanism of action of Danxiong Huoxue tablets against HO using network pharmacology and molecular docking methods. Methods: The TCMID and SymMap databases and the existing literature were used to screen the active ingredients and targets of Danxiong Huoxue tablets, and the targets of heterotopic ossification were obtained from Gene Cards, DisGeNET, and PharmGkb databases. The PPI network diagram was constructed using the String database and Cytoscape 3.9.1 software. Finally, the core targets were analyzed by GO and KEGG enrichment and validated by molecular docking. Results: A total of 39 active ingredients and 328 corresponding targets of Danxiong Huoxue tablets were identified, which were enriched in signaling pathways, such as PI3K/Akt and MAPK. Molecular docking verified that there was good binding activity between the core targets and the corresponding components. Conclusion: Danxiong Huoxue tablets may prevent and treat HO by acting on key targets, such as SRC, AKT1, JUN, and TNF, and regulating the PI3K/Akt signaling pathway and MAPK signaling pathway.
