摘要

The objective of this study was to investigate the biological activities and mechanisms of chlorogenic acid (CGA) in the treatment of septic acute liver injury (SALI) based on the network pharmacology, molecular docking, in vivo studies, and other techniques. Chlorogenic acid and potential related targets of septic acute liver injury were searched from the public databases. Then, the protein–protein interaction (PPI), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted. Subsequently, molecular docking was performed to predict the binding of the active compound to the core target. Finally, in vivo experiments were carried out for further validation. A total of 60 common targets were identified between acute septic liver injury and chlorogenic acid, among which 9 common core targets (EGFR, ESR1, GSK3B, PTGS2, TLR4, PPARA, HSP90AA1, ACE, and MMP9) were screened with Cytoscape. Molecular docking indicated that these core targets had good binding activity to chlorogenic acid (− 7.2, − 6.8, − 7.7, − 8.7, − 6.1, − 6.8, − 7.3, − 8.4, and − 8.6 kcal/mol respectively). In the SALI mouse model, chlorogenic acid can improve pathological damage to the liver and apoptosis of liver cells, and anti-inflammatory properties significantly by the TLR4/NF-κB pathway (all P < 0.05). The biological activity and regulatory network of CGA on SALI were revealed, and the anti-inflammatory effect of CGA was verified, which could be associated with the TLR4/NF-κB pathway.
