Abstract:

This study aimed to explore the mechanism of Huanglian Wendan Decoction in the treatment of Helicobacter pylori associated gastritis by network pharmacology and molecular docking methods. The active ingredients and drug target genes of Huanglian Wendan Decoction were screened using the traditional Chinese medicine system pharmacology database and analysis platform. The H. pylori associated gastritis disease-related targets were found by the GeneCards and DisGENET databases, and the common target genes of diseases and drugs were obtained via the Venny online mapping tool. Cytoscape 3.8.2 software and the STRING database were used to construct a drug-compound-target interaction network and a protein-protein interaction network diagram, respectively. Gene ontology function and Kyoto encyclopedia of genes and genomes pathway enrichment analysis were performed using the DAVID database. The target proteins and active ingredients with the top three selection scores were selected for molecular docking using Autodocktools 1.5.6 software. A total of 127 active ingredients of Huanglian Wendan Decoction were screened, such as quercetin, nobiletin, and naringenin. A total of 101 potential target proteins were obtained, such as Akt1, JUN, TNF-α, and STAT3, which involved 90 signal pathways, including the p53 signal pathway, NOD-like receptor signal pathway, and TNF signal pathway. Molecular docking results revealed that the key targets, STAT3, TP53, and Akt1, had high affinity for the active ingredients quercetin, nobiletin, and naringenin. In addition, Akt1 had the highest binding affinity for naringenin. Network pharmacology and molecular docking analysis predicted the action target and related signal pathway of Huanglian Wendan Decoction in the treatment of H. pylori associated gastritis, which will provide a theoretical basis for clinical application and subsequent experimental research.
