UPLC-MS/MS Metabolomics Reveals Babao Dan’s Mechanisms in MASH Treatment with Integrating Network Pharmacology and Molecular Docking

Background: Metabolic dysfunction-associated steatohepatitis (MASH) is a progressive disease that easily develops into cirrhosis and hepatocellular carcinoma, but its pathogenesis is not clear, and most therapeutic drugs have obvious limitations. However, Babao Dan (BBD) has a good therapeutic effect on liver disease, but its treatment mechanism is still to be studied. Therefore, we further investigated the mechanism of BBD in treating MASH. Methods: We predicted BBD-related targets through network pharmacology and further verified the binding ability of BBD-related targets through molecular docking. We also detected relevant indicators before and after model treatment, as well as metabolomics analysis and identification of the mechanism of action of BBD on MASH. Results: Through network pharmacology methods, 158 key cross targets and the top 10 core targets were identified, and it was determined that the PI3K-AKT signaling pathway plays an important regulatory role in the treatment of MASH with BBD. The molecular docking results indicate that the representative compounds quercetin and 17 Beta Estradiol have good binding activity with five core targets. Metabolomics has identified four metabolic biomarkers, such as Piceid, and it is determined that the key pathway for BBD treatment of MASH is the bile secretion pathway. Conclusions: BBD effectively treats MASH by modulating Piceid and other biomarkers, targeting ESR1 and other core proteins via quercetin and 17-beta-estradiol, and regulating the PI3K-AKT and bile secretion pathways to alleviate liver injury.
