Study on the mechanism of Dihuang Decoction in treating Alzheimer disease and diabetes mellitus with same method based on network pharmacology / 国际中医中药杂志

ABSTRACT

Objective:To study the common pharmacodynamic substance basis and potential mechanism of Dihuang Decoction in treating Alzheimer disease (AD) and diabetes mellitus (DM) with same method based on network pharmacology; To provide bioinformatics basis.Methods:The effective components of Dihuang Decoction were retrieved through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and CNKI. The drug targets were obtained by combining and UniProt database. The targets of AD and DM related diseases were obtained by GeneCards, OMIM and TTD databases respectively. Cytoscape 3.7.1 software was used to construct the Disease - drug - component - target network. R studio software was used to construct a Circos diagram of the effective compounds and disease targets.Protein-protein interaction (PPI) network was constructed using STRING platform. GO enrichment and KEGG enrichment analysis was conducted through DAVID database, Metascape, R Studio software.Results:A total of 206 active components were obtained; PPI network construction screened 51 key targets; GO enrichment analysis revealed the functions of GABA, cholinergic synapse, estrogen response, BCL-2 family protein complex and so on; KEGG enrichment analysis revealed FoxO signaling pathway, HIF-1 signaling pathway, insulin resistance pathway and other pathways.Conclusion:Dihuang Decoction has the synergistic characteristics of multiple components, multiple targets and multiple pathways in treating AD and DM with same method, mainly through proanthocyanidin B7, proanthocyanidin B5, proanthocyanidin B1 and other active ingredients, acting on TNF, IL-6, ESR1, PPARG, AKT1 and other targets, regulating FoxO signaling pathway, HIF-1 signaling pathway, etc.
