AbstractIdiopathic pulmonary fibrosis (IPF) is an interstitial lung disease that leads to progressive dyspnea and dry cough, with extracellular matrix deposition as the main pathological feature. Yifei Tongluo granules (YTG) are a traditional Chinese medicine formula that could nourish Qi-Yin, clear phlegm, and invigorate blood circulation. In this research, network pharmacology and molecular docking were used to elucidate the potential mechanism of YTG for treating IPF. A total of 278 biologically active compounds were included in YTG, and 16 compounds were selected for pharmacological analysis and molecular docking through "drugs-compounds-intersecting targets of YTG and IPF" network construction. Protein-protein interaction network was constructed using 330 YTG-IPF intersecting targets. Furthermore, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were performed. A total of 10 core targets were screened by protein-protein interaction, and molecular docking was used to further validate the binding ability of the compounds to the core targets. The network pharmacology and molecular docking results showed that Danshenol A, isorhamnetin, Ginsenoside-Rh4, quercetin, and kaempferol might be the main active compounds in the treatment of IPF by YTG, whereas MAPK1, MAPK3, EGFR, and SRC are the core targets while PI3K/AKT pathway and MAPK pathway are the main signaling pathways through which YTG regulates relevant biological processes to intervene in IPF. This study shows that YTG can treat IPF by inhibiting the epithelial-mesenchymal transit process, fibroblast proliferation, fibroblast-to-myofibroblast conversion, myofibroblast anti-apoptosis, collagen expression, and other mechanisms.YTG can be widely used as an adjuvant therapy for IPF in clinical practice, and this study provides the basis for subsequent experimental studies.Copyright © 2023 the Author(s).
