Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) has a multifactorial and complex pathogenesis. Notably, the disorder of Bile acid (BA) metabolism and lipid metabolism-induced lipotoxicity are the main risk factors of MASLD. Lupeol, traditional regional medicine from Xinjiang, has a long history of use for its anti-inflammatory, anti-tumor, and immune-modulating properties. Recent research suggests its potential as a therapeutic option for MASLD due to its proposed binding capacity to the nuclear BA receptor, Farnesoid X receptor (FXR), hence could represent a therapeutic option for MASLD. In this study, a natural triterpenoid drug lupeol improved BA metabolism and MASLD in mice through the FXR signaling pathway and the gut-liver axis. Furthermore, lupeol effectively restored gut healthiness and improved intestinal immunity, barrier integrity, and inflammation, as indicated by the reconstructed gut flora. Compared with fenofibrate (Feno), lupeol treatment significantly reduced weight gain, fat deposition, and liver injury, decreased serum total cholesterol (TC) and triglyceride (TG) levels, and alleviated hepatic steatosis and liver inflammation. BA analysis showed that lupeol treatment accelerated BA efflux and decreased uptake of BA by increasing hepatic FXR and bile salt export pump (BSEP) expression. Gut microbiota alterations could be related to enhanced fecal BA excretion in lupeol-treated mice. Therefore, consumption of lupeol may prevent HFD-induced MASLD and BA accumulation, possibly via the FXR signaling pathway and regulating the gut microbiota.

Comput Biol Chem 2024; 110:108088. [PMID: 38685167 DOI: 10.1016/j.compbiolchem.2024.108088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 04/05/2024] [Accepted: 04/24/2024] [Indexed: 05/02/2024]
Abstract
Cichorium glandulosum, a common traditional Chinese medicine used by Uyghur and Mongolian ethnic groups, is recognized for its potential to ameliorate metabolic disorders. However, the specific efficacy and mechanisms of Cichorium glandulosum in treating the comorbidity of hyperuricaemia and hyperlipidaemia remain unexplored. This study aims to explore the pharmacological effects and mechanisms of Cichorium glandulosum on this comorbidity through a combination of animal experiments, network pharmacology, and molecular docking techniques. A rat model of hyperuricaemia combined with hyperlipidaemia was established through a high-fat and high-purine diet, and the effective parts of the aqueous extract of Cichorium glandulosum to reduce uric acid and lipid levels were screened and the components of the parts were analysed by LC-MS/MS. The active components, core targets, and key pathways were analysed using network pharmacology and validated by molecular docking. Animal experimental results indicated that the n-butanol extract of Cichorium glandulosum showed a significant therapeutic effect on this comorbidity. Analysis of the n-butanol extract yielded 35 active ingredients and 138 intersecting targets related to diseases. Key targets identified through compound-target-pathway (C-T-P) and Protein-Protein Interaction (PPI) analyses included RELA, CASP3, PTGS2, TNF, and ESR1. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed 2515 functional items and 164 pathways, respectively. Molecular docking demonstrated that isochlorogenic acid A, baicalin, chicoric acid, and lactucopicrin showed the highest binding affinity to RELA and PTGS2. The n-butanol fraction from the aqueous extract of Cichorium glandulosum was found to reduce uric acid and lipid levels effectively. In summary, Cichorium glandulosum has a therapeutic effect on hyperuricaemia combined with hyperlipidaemia through its multi-component, multi-target, and multi-pathway characteristics.

Abstract
Cichorium intybus L. (Asteraceae), belonging to the tribe Cichorieae of the family Asteraceae, has a long history as an edible and medicinal food. Sesquiterpene lactones are commonly considered as its major active constituents. In the current study, five unreported sesquiterpene lactones, including one 12,8-guaianolide and four 12,6-guaianolides were isolated from C. intybus roots, as well as 16 known analogues. The planar structures and relative configurations of these compounds were elucidated by extensive spectroscopic analysis. The absolute configurations were determined by the time-dependent density functional theory (TDDFT)-based electronic circular dichroism (ECD) calculation method. Bioassay results showed that seven of the isolates exhibited remarkable NO production inhibitory activity in LPS-stimulated RAW264.7 macrophages, with IC50 values ranging from 1.83 to 38.81 μM. Some of them can significantly decrease the secretion of inflammatory cytokines (TNF-α and IL-6). Cytotoxicity assays demonstrated that intybusins B, as well as four known compounds, displayed obvious inhibitory activities against four human tumor cells, with IC50 values ranging from 9.01 to 27.07 μM.

Abstract
Samwirin A (SW), a natural compound isolated from Sambucus williamsii or Rourea harmandiana, is known to exhibit potent antiosteoporosis activity and promote cell proliferation in rat osteoblast-like UMR 106 cells. Antiosteoporosis activity suggests that the compound must also exhibit antioxidant activity but this has not been studied thus far. In the present study, the antioxidant activity of SW was examined by experimental and computational studies. It was found that SW exhibits good hydroperoxyl scavenging activity, particularly in water at physiological pH (k overall = 1.01 × 107 M-1 s-1). The single-electron transfer mechanism defines the HOO• + SW reaction in water, while the activity in the lipid medium is moderate and it follows the formal hydrogen transfer mechanism. The rate constant of the HOO• scavenging reaction in the aqueous solution is about 78 times higher than the reference compound Trolox. The computational results are in line with experimental data underscoring that SW is a promising radical scavenger in aqueous media at physiological pH.
