But little is known about the potential mechanism. This study aims to elucidate the effective components and analgesic mechanism based on network pharmacology. Methods: TCMSP was screened to collect the possible active ingredients and their CAS and SMILES was searched in Pubchem and further be used for reverse molecular docking in Swiss Target Prediction database to obtain potential targets. Pain-related molecules were obtained from GeenCards database, and the predicted targets of Paeonia Lactiflora for pain treatment were selected by Wayne diagram. For mechanism analysis, the protein-protein interactions were constructed by String, the GO analysis and KEGG analysis were conducted in DAVID. Results: Through GO analysis and KEGG analysis, we found that the pain related signaling pathways mainly involved in serotonergic synapse, calcium signaling pathway, inflammatory mediator TRP channels. Using network-based systems biology and molecular docking analyses, we predicted that 11 active ingredients in Paeonia Lactiflora has the analgesic effects with 97 potential targets. PRKCA, CASP3, ALOX15, SLC6A4, PRKCG, ALOX5, PRKCB, ALOX12, EGFR, ADRB2, RYR3, RYR1, NOS2, PTAFR, PRKCQ, and PRKCD were involved in the analgesic effects of Paeonia Lactiflora. Conclusion: Paeonia Lactiflora may alleviate pain through inflammatory mediator regulation of TRP channels, Ca2+ signaling pathway and 5-HT receptor. PRKCA, PRKCB, PRKCD,PRKCQ, and PRKCG may be new targets for pain treatment.展开更多

文摘Objective:To explore the mechanism of paeoniflorin(PF)on osteoarthritis(OA)synovial inflammation from network pharmacology to experimental pharmacology.Methods:Targets of OA were constructed by detecting the database of network database platforms(Therapeutic Target database,Drug Bank and Gene Cards),and the targets of PF were constructed by Pub Chem and Herbal Ingredients'Targets database.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis of these co-targeted genes were conducted via Database for Annotation,Visualization,and Integrated Discovery(DAVID)database,and protein-protein interaction(PPI)networks were conducted via the search tool for the retrieval of interacting genes(STRING)database.Cell counting kit-8(CCK-8)assay was performed to assess the potential toxicity of PF on human OA fibroblast-like synoviocytes(FLS),quantitative real-time polymerase chain reaction(q PCR),enzyme-linked immunosorbent assay(ELISA)and Western blot were used to verify the potential mechanism of PF in synovial inflammation.Results:Twenty-six co-targeted genes were identified.GO enrichment results showed that these co-targeted genes were most likely localized in the cytoplasm,and the biological processes mainly involved'cellular response to hypoxia''lipopolysaccharide(LPS)-mediated signaling pathway'and'positive regulation of gene expression'.KEGG pathway analysis indicated that these co-targeted genes may function through pathways associated with'hypoxia-inducible factor-1(HIF-1)signaling pathway'and'tumornecrosis factor(TNF)signaling pathway'.The PPI network showed that the top 3 hub genes were TP53,TNF,and CASP3.Molecular docking results showed that PF was well docking with TNF.CCK-8 showed no potential toxicity of 10,20 and 50μmol/L PF on human OA FLS.And PF significantly decreased the expression levels of interleukin-1β,interleukin-6,TNF-αmatrix metalloproteinase 13(MMP13),and a disintegrin and metalloproteinase with thrombospondin motifs 5(ADAMTS5)and TNF-αin LPS-induced OA FLS.Conclusion:PF exhibited potent anti-inflammatory effect in OA synovial inflammation.

文摘White mugwort (Artemisia lactiflora Wall.) is known as a medicinal herb containing phytochemicals with antioxidant and bio-activity.The optimal concentration of ethanol was investigated for extracting polyphenols from the fresh aerial part and dried powder of white mugwort as expressed by total phenolic content (TPC),phenolic compounds,antioxidant,anti-inflammatory,and anti-adipogenic activity.Among various ethanol concentrations (0,25,50 or 95%) used in the extraction process,the freeze-dried extract from fresh aerial part (FE) extracted with 95% ethanol expressed the highest antioxidant activity (DPPH radical scavenging IC50 of 0.817 ± 0.06 μl/mg dry weight (DW) and FRAP value of 11.40 ± 0.86 mmol Fe(II)/g DW) and the highest TPC (61.46 ± 3.09 mgGAE/g DW).While,the freeze-dried extract from dried powder (PE) exhibited the prominent antioxidant properties (DPPH radical scavenging IC50 of 0.975 ± 0.03 μl/mg DW and FRAP value of 07.60 ± 0.22 mmol Fe(II)/g DW),TPC (48.11 ± 1.45 mgGAE/g DW) when extracted with 50% ethanol.Seven phenolic compounds—two phenolic acids (gallic acid and tannic acid) and five flavonoids (apigenin,isoquercetin,quercetin,rutin,and catechin) were identified in FE and PE using HPLC-DAD/MS.The inflammatory genes were down-regulated in lipopolysaccharide-stimulated THP-1 monocytes treated with PE,suggesting anti-inflammatory activity.Lipid accumulation in 3T3-L1 adipocytes treated with FE at 60 μ gGAE/mL decreased to 12.8%,while the decrease of 36.8% was detected in PE.Hence,flavonoids were suggested to be responsible for the stronger bioactivity of PE over FE.Moreover,this work originally revealed the investigation of the anti-inflammatory and anti-adipogenic activity of white mugwort on THP-1 and 3T3-L1 cells.
