降尿酸食药同源组合物的筛选及其作用机制研究

Screening of Urate-lowering Food-Medicine Homologous Combinations and Investigation of the Mechanism

  • 摘要: 目的:以芹菜籽、黑枸杞、桦褐孔菌等10种食药同源物质为研究对象,筛选具有降尿酸功能的食药同源组合物配方并探究其缓解高尿酸血症的机制。方法:采用体外抗氧化能力和黄嘌呤氧化酶抑制能力筛选具有高体外活性的食药同源单体,通过“均匀设计法”优化具有高活性的食药同源组合物(food-medicine homologous combinations 1,FMHC1),利用体外消化模拟探究FMHC1的胃肠道行为,再以腺苷和黄嘌呤氧化酶诱导高尿酸血症HK-2细胞模型,通过检测细胞上清液中的尿酸含量,IL-6、TNF-α、IL-10、TGF-β的水平以及MDA、CAT、SOD、GSH-Px的活性,评价FMHC1对细胞模型的保护作用。结果:获得FMHC1配方:芹菜籽41%、桦褐孔菌39%、黑枸杞10%、金银花5%以及玉米须5%,且FMHC1经胃肠消化后黄嘌呤氧化酶抑制活性仅下降4.89%±1.02%和11.08%±1.59%,表现出优异的生物利用度,在高尿酸血症细胞模型中,FMHC1使尿酸水平降低35.52%,并通过双向调节炎症因子(上调IL-6 25.82%、TNF-α 66.51%和下调IL-10 73.10%、TGF-β 49.18%),有效改善炎症反应,同时显著增强抗氧化能力,使MDA水平降低61.20%,CAT、SOD、GSH-Px的活性分别提高2.86倍、0.63倍、2.00倍。结论:筛选的FMHC1通过多途径协同作用,具备开发为高尿酸血症膳食干预剂的潜力。

     

    Abstract: Objective: To develop potential formulations for alleviating hyperuricemia, we screened approximately 10 medicinal and food homologous ingredients, including Apium graveolens L., Lycium ruthenicum Murray, and Inonotus obliquus, and explored their biological functions and underlying mechanisms. Methods: Based on the quantitative analysis from in vitro antioxidant capacity and xanthine oxidase inhibition for each candidate, the optimized formulation containing different ingredients, namely the homologous combinations 1 (FMHC1), could be obtained using the “Uniform Design Method”. Further, the in vitro digestion behavior of FMHC1 was investigated. Besides, the protection efficiency on the hyperuricemia cell model that was established by inducing HK-2 cells with adenosine and xanthine oxidase was evaluated, by determining the levels of uric acid in cell supernatant, pro-inflammatory cytokines (IL-6, TNF-α), anti-inflammatory cytokines (IL-10, TGF-β), as well as the oxidative stress markers (MDA, CAT, SOD, GSH-Px). Results: The ideal formulation for FMHC1 was 41% Apium graveolens L., 39% Inonotus obliquus, 10% Lycium ruthenicum Murray, 5% Lonicera japonica Thunb, and 5% Stigma Maydis. The experimental results showed that FMHC1 displayed high bioavailability, where the inhibitory efficiency for xanthine oxidase was decreased by only 4.89%±1.02% (gastric phase) and 11.08%±1.59% (intestinal phase) after in vitro digestion. Moreover, the uric acid level in the hyperuricemia cell model was down-regulated by 35.52%. These occurrences might be attributed to the ameliorated inflammatory responses through regulation of cytokines. Upon the administration, the IL-6 and TNF-α were upregulated by 25.82% and 66.51%, respectively, whereas the corresponding IL-10 and TGF-β were downregulated by 73.10% and 49.18%. Besides, the antioxidant capacity was significantly enhanced. As a result, about 61.20% loss for MDA level in cell line occurred, and the activities for CAT, SOD, and GSH-Px were enhanced by 2.86, 0.63, and 2.00 times, respectively. Conclusion: The screened FMHC1 demonstrates great potential in dealing with hyperuricemia through multiple pathways, and could be considered to be a promising diet in disease intervention.
