To explore the main active components, potential targets and mechanisms of Polygonatum in the treatment of Alzheimer's disease (AD) by using network pharmacological techniques and methods.
The active components of Polygonatum were screened in TCMSP. AD-related targets were retrieved from GeneCards database, TTD database and DrugBank database. Cytoscape 3.7.2 software was used to establish the "yellow essence-component-target" network, which was imported into STRING database to obtain the target PPI network. Key genes were screened using "CytoHubba" function, and GO biological process and KEGG pathway enrichment analysis were performed.
β-Sitosterol, baicalin, diosgenin and other active components in Polygonatum may exert an effect of prevention and treatment of AD through AKT1, CASP3, TP53, VEGFA, HIF1, mTOR and other key gene targets to regulate neurodegenerative pathways, including various diseases, PI3K-Akt signaling pathway, MAPK signaling pathway, and apoptosis signaling pathway.
Polygonatum may regulate and integrate multi-components, multi-targets and multi-pathways to achieve prevention and treatment of AD.
