Network Pharmacology Study on the Mechanism of Wutou Decoction in the Treatment of Osteoarthritis / 中国药房

ABSTRACT

OBECTIVE： To study the mechanism of Wutou decoction in the treatment of osteoarthritis， and to provide a new direction and target for the treatment of osteoarthritis. METHODS： Using oral bioavailability （OB）≥30％， drug like （DL）≥0.18％ as index， active components were screened from Wutou decoction by using TCM systematic pharmacological analysis platform （TCMSP）， such as Aconitum carmichaelii， Ephedra sinica， Astragalus propinquus， Paeonia tactilora， Glycyrrhiza uralensis. Targets of osteoarthritis were obtained by retrieving therapeutic targets database （TTD） and mining thip data from gene expression database （GEO）. Target genes were analyzed by GO and KEGG pathway enrichment analysis were performed by using DAVID database. RESULTS： A total of 30 active components were screened， including quercetin， terpenoids and gardenol； 31 targets related to osteoarthritis were obtained， including β2 adrenergic receptor， arachidonate 5-lipoxygenase and androgen receptor. The biological process of Wutou decoction in treatment of osteoarthritis was mainly related to the IL-1 receptor signal transduction， synergistic activation of peroxidase proliferation activated receptor， signal transduction of tyrosine kinase receptor 2. It mainly regulated tumor necrosis factor signaling pathway， vascular endothelial growth factor signaling pathway， osteoclasts differentiation signaling pathway， nuclear factor κB signaling pathway， Toll-like receptor signaling pathway so as to play a role in the treatment of osteoarthritis. CONCLUSIONS： The study analysis the potential mechanism of Wutou decoction in the treatment of osteoarthritis based on network pharmacology， which can provide reference for further study on the material basis and target of Wutou decoction in the treatment of osteoarthritis.
