Objective:
To explore the material basis of Caulis sinomenii (CS) in treating osteoarthritis (OA), and to give a pharmacodynamic illustration for the multi-targeting therapeutics of CS.
Methods:
The computational methods, consisting of molecular docking and biological network were carried out to search the database targeting twelve important OA related enzymes: ASAMTS4, ASAMTS5, MMP-1, MMP-3, MMP-13, MMP-8, MMP-2, COX-2, COX-1, IL-1beta, TNF-alpha, iNOS, and map the ligand-target interaction networks about molecules from CS and DrugBank. After that, an aggregate analysis was performed to analyze the mechanisms of compositions in CS.
Results:
Totally 14 had good interaction in all molecules in database with two or more than two of the OA correlated enzymes, and 6 molecules had interaction with four or more enzymes. Moreover, both herb ligand-target interaction network and drug ligand-target interaction network were similar in the interaction profiles and network features, which revealed multi-drugs effects in CS.
Conclusions:
There were a lot of multi-target molecules in CS, providing pharmacodynamic illustrations for the multi-target therapeutics of Chinese medicine. Meanwhile, they supplied certain reference and inspiration for finding out new drugs for OA therapy.
