Abstract:
Background: At present, there are no effective pharmacologic therapies for attenuating the course of
osteoarthritis (OA) in humans and current therapies are geared to mitigating symptoms. Fangfeng decoction
(FFD) is a traditional Chinese medicine prescribed for the treatment of OA. In the past, FFD has achieved positive
clinical outcomes in alleviating the symptoms of OA in China. However, its mechanism of action has not
yet been clarified.
Objective: The objective of this study is to investigate and explore the mechanism of FFD and how the compound
interacts with the target of OA; network pharmacology and molecular docking methods were applied in
this study.
Methods: The active components of FFD were screened by Traditional Chinese Medicine Systems Pharmacology
(TCMSP) database according to the inclusion criteria as oral bioactivity (OB) ≥ 30% and drug likeness (DL)
≥ 0.18. Then, gene name conversion was performed through the UniProt website. The related target genes of
OA were obtained from the Genecards database. Core components, targets, and signaling pathways were obtained
through compound-target-pathway (C-T-P) and protein-protein interaction (PPI) networks were built using
Cytoscape 3.8.2 software. Matescape database was utilized to get gene ontology (GO) function enrichment
and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of gene targets. The interactions
of key targets and components were analyzed by molecular docking in Sybyl 2.1 software.
Results: A total of 166 potential effective components, 148 FFD-related targets, and 3786 OA-related targets
were obtained. Finally, 89 common potential target genes were confirmed. Pathway enrichment results showed
that HIF-1 and CAMP signaling pathways were considered key pathways. The screening of core components
and targets was achieved through the CTP network. The core targets and active components were obtained according
to the CTP network. The molecular docking results showed that quercetin, medicarpin, and wogonin of
FFD could bind to NOS2, PTGS2, and AR, respectively.
Conclusion: FFD is effective in the treatment of OA. It may be caused by the effective binding of the relevant
active components of FFD to the targets of OA.
