Background:
Liver fibrosis, a chronic liver disease, threatens people's health, increases the burden of healthcare, and currently lacks effective treatment measures. Bugantang (BGT) is a traditional Chinese herbal prescription from Jin Kui Yi with promising potential for treating liver fibrosis. Despite this potential, the efficacy and mechanism for treating liver fibrosis remain unclear.
Objective:
To primarily prove the efficacy, predict the active components of BGT, and explore the mechanism of BGT on liver fibrosis.
Methods:
The liver condition of CCL4-induced mice was examined using hematoxylin and eosin staining. The targets and active compounds of BGT were sourced from HERB and TCMSP databases, while the targets related to liver fibrosis were acquired from DisGeNET, Gene Expression Omnibus, and GeneCards databases. The core targets were identified, and the network of protein-protein interactions was established. KEGG and GO analyses were performed on DAVID. Molecular docking and molecular dynamics simulations assessed the active components' interactions with potential targets.
Results And Discussion:
A total of 215 targets and 152 active compounds were identified for BGT. The network analysis identified kaempferol, quercetin, 2-(2,4-dihydroxyphenyl)-7-hydroxy- 4H-chromen-4-one, sitosterol, naringenin, adenosine, plo, and beta-sitosterol as potential key compounds, and AKT1, MMP9, SRC, TNF, ESR1, NF-κB, and PPARG as potential key targets. KEGG and GO analyses revealed that the therapeutic effect of BGT on liver fibrosis may be associated with the PI3K-AKT and MAPK signaling pathways, as well as cell apoptosis, protein phosphorylation, and inflammation. Molecular docking demonstrated high-affinity binding of the identified targets to the active compounds. Additionally, molecular dynamics simulation further confirmed that the bindings of AKT1-beta-sitosterol and MMP9-quercetin exhibited good stability.
Conclusions:
The potential of BGT in alleviating liver fibrosis may be attributed to a combination of various active compounds, targets, and pathways. These results could support the use of BGT in treating liver fibrosis and facilitate the development of new drug candidates for this condition.

Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
