However, the mechanisms by which its naturally self-assembled supramolecular complexes, formed during aqueous decoction, contribute to therapeutic outcomes remain underexplored, representing a critical gap in understanding TCM's holistic pharmacology.</div></div><div><h3>Aim of the study</h3><div>This study sought to elucidate the self-assembly mechanisms underlying QCWZD's therapeutic effects, with a focus on characterizing the anti-inflammatory properties of its naturally self-assembled complexes formed during decoction and their role in UC intervention.</div></div><div><h3>Methods</h3><div>The submicron precipitate of QCWZD was isolated via gradient centrifugation and characterized for size and morphology using dynamic light scattering (DLS) and scanning electron microscopy (SEM). A DSS-induced murine UC model was used to evaluate the efficacy of QCWZD and its fractions (supernatant and submicron precipitate). Meanwhile, UPLC-ZenoTOF-MS/MS and triple quadrupole LC-MS/MS were employed to identify and quantify the bioactive components. Representative self-assembled complexes were synthesized under conditions mimicking decoction and characterized using DLS and SEM. Thermodynamic binding behavior was probed using isothermal titration calorimetry (ITC). Non-covalent interaction mechanisms of complex formation were characterized by UV, FT-IR, and <sup>1</sup>H NMR spectroscopy. Anti-inflammatory activity of the self-assembled complexes was validated in LPS-stimulated RAW264.7 macrophages.</div></div><div><h3>Results</h3><div>QCWZD's submicron precipitate accelerated UC remission in mice, reducing the disease activity index (DAI), restoring colon length, and suppressing NF-κB p65 phosphorylation compared to the model group. Mass spectrometry identified berberine-glycyrrhizic acid (BER-GL) and matrine-glycyrrhizic acid (MAT-GL) as dominant self-assembled complexes. ITC revealed binding affinity between glycyrrhizic acid (GL) and alkaloids (BER: <em>K</em><sub>d</sub> = 2.55 × 10<sup>−4</sup> M, 1:1 binding ratio; MAT: <em>K</em><sub>d</sub> = 6.77 × 10<sup>−4</sup> M, 1:2 binding ratio), driven by enthalpy. Charge-transfer and hydrogen-bonding interactions between glycyrrhizic acid (GL) and the alkaloids berberine (BER) and matrine (MAT) lead to stable self-assemblies. BER-GL and MAT-GL complexes significantly suppressed pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) while upregulating IL-10 in RAW264.7 cells, outperforming free alkaloids.</div></div><div><h3>Conclusion</h3><div>Building on QCWZD's established efficacy in treating ulcerative colitis (UC) via the NF-κB pathway, this work demonstrates that the aqueous self-assembly of BER-GL and MAT-GL, derived from QCWZD's submicron p","PeriodicalId":15761,"journal":{"name":"Journal of ethnopharmacology","volume":"352 ","pages":"Article 120169"},"PeriodicalIF":4.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144336643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, candidate genes were obtained by overlapping differentially expressed genes (DEGs) from NAFLD and control samples in GSE63067 with the drug target genes. Subsequently, candidate biomarkers were further obtained using the algorithm in cytoHubba plug-in. Biomarkers were further identified via receiver operating characteristic (ROC) analysis and expression validation, and enrichment analysis was executed to explore the potential mechanisms of NAFLD biomarkers. HPLC and UPLC/QE-HFX were used to determine the chemical components of JWYCHT. Finally, the findings were validated through molecular biology experiments involving a mouse model of NAFLD induced by high-fat diet.</div></div><div><h3>Results</h3><div>A total of 416 DEGs were acquired, with 51 candidate genes subjected to enrichment analysis.

ROC analysis confirmed CASP1 and CXCL10 as viable biomarkers, with the latter (odds ratio = 1.305, <em>p</em> < 0.05) emerging as a risk factor for NAFLD. 41 compounds were identified by UPLC/QE-HFX in JWYCHT. The HPLC results demonstrated distinct variations in chemical profiles between JWYCHT, YCHT, and their component medicinal herbs. A series of molecular experiments revealed that JWYCHT effectively treated NAFLD in the mouse model.
