Mechanism of Berberidis Cortex in treating type 2 diabetes mellitus based on network pharmacology and molecular docking
Objective To explore the effective substances and mechanism of Berberidis Cortex in treating type 2 diabetes mellitus.Methods Based on the absorbed components derived from Berberidis Cortex,SwissADME,TCMSP,and Swiss Target Prediction databases were employed to conduct an initial activity assessment and forecast potential targets.Subsequently,GeneCards,DisGeNET,and DrugBank databases were utilized to obtain targets related to type 2 diabetes mellitus.The STRING database was used to construct a protein interaction network of targets for core target selection.R language was applied for GO function and KEGG pathway analysis based on the screening results.Finally,Cytoscape 3.10.1 software was used to construct an interaction network of"herbs-absorbed components-targets-signal pathways-disease"to screen core and key targets.Additionally,molecular docking was performed to verify the biological activity of"core components-key targets".Results After preliminary activity screening,28 candidate active components were obtained,and subsequent Swiss Target Prediction predicted interactions with 571 components.Network pharmacology analysis revealed that Berberidis Cortex had 306 intersecting targets with type 2 diabetes mellitus.Berberidis Cortex potentially exerts its anti-diabetic effects through components such as 8-oxoberberine,bufotenine,bufotenidine,berberine,and jatrorrhizine,acting on key targets like PIK3CA,MAPK1,IKBKB,Akt1,and EGFR.This modulation occurs through PI3K/Akt,MAPK,TNF,and NF-κB signaling pathways,collectively contributing to its anti-diabetic effects.Conclusion By integrating the identification of absorbed components,network pharmacology,and molecular docking results,predicted potential therapeutic components and targets of Berberidis Cortex in treating type 2 diabetes mellitus were preliminarily predicted.This provides a reference for revealing the pharmacological substance basis and mechanism of action of Berberidis Cortex and a target for further research on treating type 2 diabetes mellitus with Berberidis Cortex.
