Study on the Molecular Mechanism of Danggui Buxue Decoction in Intervention of Perimenopausal Syndrome Based on Network Pharmacology and Molecular Docking

[Objectives]This study was conducted to explore the intervention mechanism of Danggui Buxue Decoction in perimenopausal syndrome based on network pharmacology and molecular docking.[Methods]The chemical components and targets of Danggui Buxue Decoction were acquired through the TCMSP database,and the main targets of perimenopausal syndrome were obtained through the GeneCards database.The component targets and disease targets were intersected,and combining with active components and Chinese herbs in the decoction,a traditional Chinese medicine-component-target network was constructed using Cytoscape 3.7.1 software.The STRING platform was employed for protein-protein interaction analysis.The DAVID analysis platform was used to conduct target GO and KEGG enrichment analysis,so as to predict the action mechanism Danggui Buxue Decoction.Finally,an active component-disease target-signal pathway network diagram was constructed.[Results]Twenty two components in Danggui Buxue Decoction related to perimenopausal syndrome and 120 corresponding targets were obtained,including active components such as 1,7-dihydroxy-3,9-dimquercetin and kaempferol,and key targets such as TNF,ESR1 and PPARG.The results of GO analysis and KEEG analysis indicated that Danggui Buxue Decoction might regulate the transcription of RNA polymerase II promoter,DNA templating,gene expression,signal transduction,hypoxia response and other biological processes by regulating multiple signal pathways such as chemical carcinogenesis-receptor activation,cancer pathways,lipid and atherosclerosis,tryptophan metabolism,malaria,steroid hormone biosynthesis and chemical carcinogenesis-DNA adduct.[Conclusions]Danggui Buxue Decoction intervenes in perimenopausal syndrome through multiple components,targets and pathways,providing a basis for elucidating the intervention mechanism of Danggui Buxue Decoction and expanding its clinical application.

Danggui Buxue decoction promotes proliferation and differentiation of Caco-2 cells and antagonizes obesity by stimulating apolipoprotein-IV expression

Background:Chinese medicine has been proposed as a novel approach to the prevention of metabolic disorders such as obesity.Danggui Buxue decoction,a decoction prepared from Huangqi(Astragali Radix)and Danggui(Angelicae Sinensis Radix),has been used to nourish vitality and enhance blood circulation in traditional Chinese medicine.However,the effect of Danggui Buxue decoction on obesity is still primarily unknown.Methods:Cell proliferation,differentiation,and apolipoprotein-IV transcription were investigated to explore the function of Danggui Buxue decoction by methyl thiazolyl tetrazolium assay,alkaline phosphatase assay,and luciferase assay,respectively.Results:Danggui Buxue decoction promoted cell growth by up to 15%(P=0.034)and induced cell differentiation by up to 38%(P=0.006)at 0.3 mg/mL.Moreover,Danggui Buxue decoction enhanced the transcription of apolipoprotein-IV by 2.4 times(P=0.027),activating its promoter by 28.9%(P=0.031)at 0.3 mg/mL.In addition,Danggui Buxue decoction functioned in a dose-dependent manner.Conclusion:These results suggest that Danggui Buxue decoction promotes cell differentiation by enhancing apolipoprotein-IV transcription and alkaline phosphatase activity,and it may also have a potential anti-obesity effect because apolipoprotein-IV transcription is closely related to the reduction of food intake.

Dissecting the underlying pharmaceutical mechanism of Danggui Buxue decoction acting on idiopathic pulmonary fibrosis with network pharmacology

Backgroud:Danggui Buxue decoction(DBD),a classical prescription in traditional Chinese medicine,has been found to have protective effect on bleomycin-induced pulmonary fibrosis in rats by reducing alveolar inflammation and fibrosis.However,the biological activity of individual chemical components and mechanism of action of whole formula are not clear.Methods:Potential targets of active ingredients of DBD were collected through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and SymMap database.Target genes related to idiopathic pulmonary fibrosis were obtained from the Online Mendelian Inheritance in Man database,Therapeutic Targets Database and Gkb database.Then,the common targets were obtained by overlapping the potential targets of active ingredients in DBD and diseases related targets.The selected targets were subjected to Kyoto Encyclopedia of Genes and Genomes signaling pathway and Gene Ontology analysis,and the network map of active component-target-pathway was established using Cytoscape 3.7.1 software.The active components of DBD with most targets were selected for fibrosis-related marker verification.The mRNA and protein expression of fibrosis markers,α-smooth muscle actin,collagen 1 and fibronectin,were detected in TGF-β1-induced fibroblast cell line after treatment with the active components.Results:The 14 active ingredients,such as quercetin and kaempferol,were screened from DBD.It acts on 26 targets like estrogen receptor 2 and prostaglandin-endoperoxide synthase 2,and mainly involves 38 signaling pathways such as cell inflammation and autophagy.Kaempferol and quercetin are the two compounds with the highest network regulation,which can inhibit the transformation of fibroblasts into myofibroblasts and reduce the expression of fibrosis markersα-smooth muscle actin,collagen 1 and fibronectin.Conclusion:The integration mode of multi-component,multi-target,multi-channel and mechanism of DBD in the treatment of idiopathic pulmonary fibrosis are predicted by means of network pharmacology.Our study could indicate the direction of further anti-fibrotic mechanism research.
