Abstract:
ObjectiveBased on network pharmacology and molecular docking techniques， the mechanism of essential oil from Chimonanthus nitens leaves （CLO） in the treatment of acute lung injury （ALI） was predicted， and a rat model of ALI was established to verify the mechanism of CLO. MethodThe composition of CLO was determined by gas chromatography-mass spectrometry （GC-MS）. The component targets were obtained from PharmMapper and SwissTargetPrediction databases， ALI-related targets were obtained from GeneCards， Online Mendelian Inheritance in Man （OMIM） and DisGeNET， cross-over analysis with differential expressed genes （DEGs） of ALI obtained from Gene Expression Omnibus （GEO） on the Venny 2.1.0 platform yielded potential anti-ALI targets of CLO. Protein-protein interaction （PPI） analysis of potential targets was carried out by STRING 11.5. The tissue expression profiles of potential targets were obtained from the National Center for Biotechnology Information （NCBI） and the target tissue distribution maps were constructed. Potential targets were analyzed for Gene Ontology （GO） function and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment by RStudio 4.0.0 software. Composition-target-pathway network was constructed by Cytoscape 3.9.1 software， and key components and pathways were screened out and verified by molecular docking. ALI model was established by lipopolysaccharide （LPS） induction， levels of interleukin （IL）-6 and tumor necrosis factor （TNF）-α in serum of rats were measured， the expression levels of IL-17 protein in the lung tissue of ALI rats were analyzed by immunohistochemistry. ResultA total of 19 components of CLO were identified by GC-MS， and 18 potential targets were obtained by target screening. After PPI analysis， 15 target proteins with interaction relationship were obtained， further analysis showed that they were highly expressed in lung and thymus. The network diagram of component-target-pathway was analyzed to obtain the key components， including bornyl acetate， linalool， elemol， geranyl isobutyrate， and the core targets of matrix metalloproteinase 13 （MMP13）， S100 calcium binding protein A9 （S100A9）， spleen tyrosine kinase （SYK）， as well as the main signaling pathways， such as IL-17 and TNF. The results of molecular docking showed that the key components were stably bound to MMP13 and S100A9 of IL-17 signaling pathway. The results of pharmacological experiment confirmed that CLO could significantly inhibit the expression of IL-6 and TNF-α in serum of ALI rats， and decrease the expression of IL-17 protein in lung tissue of ALI rats. ConclusionCLO can achieve the therapeutic effect on ALI and protect lung tissue， the mechanism may be related to the decrease of the expression of IL-6 and TNF-α in serum and the inhibition of the activation of IL-17 signaling pathway in lung tissue of ALI rats.
