This study explored the uric acid-lowering effects of hederagenin (HD) through molecular docking analysis and a chronic hyperuricemia (HUA) mouse model. Molecular docking was performed to evaluate HD's interactions key urate-regulating proteins, including xanthine oxidase (XOD), ABCG2, OAT1, URAT1, and GLUT9. To establish a chronic HUA model, mice were fed a yeast-adenine diet supplemented with potassium oxonate. The mice were randomly assigned to six groups: normal control, HUA model control, benzbromarone (BEN) group, and three HD treatment groups at doses of 50, 100, and 200 mg/kg. Serum uric acid (UA) levels, liver and kidney function indicators, XOD activity, and oxidative stress markers were assessed. Histopathological analyses of the liver and kidney were also conducted. In addition, gene and protein expression levels of urate transporters and inflammatory markers were assessed using RT-PCR and Western blotting. The results showed that HD interacts with XOD and urate transporters, significantly reducing serum UA levels and inhibiting XOD activity in HUA model. It also modulated the expression of urate transporter to enhance UA excretion. Moreover, HD protected liver and kidney function by reducing pro-inflammatory cytokine levels and inhibiting the TLR4/Myd88/NF-κB and NLRP3 signaling pathways. These findings suggest HD may serve as a promising therapeutic agent for lowing uric acid and preventing organ damage associated with HUA.
本研究通过分子对接分析和慢性高尿酸血症(HUA)小鼠模型,探讨了常春藤皂苷元(HD)的降尿酸作用。进行分子对接以评估HD与关键尿酸调节蛋白的相互作用,这些蛋白包括黄嘌呤氧化酶(XOD)、ABCG2、OAT1、URAT1和GLUT9。为建立慢性HUA模型,给小鼠喂食补充了氧嗪酸钾的酵母 - 腺嘌呤饮食。将小鼠随机分为六组:正常对照组、HUA模型对照组、苯溴马隆(BEN)组以及三个剂量分别为50、100和200mg/kg的HD治疗组。评估血清尿酸(UA)水平、肝肾功能指标、XOD活性和氧化应激标志物。还对肝脏和肾脏进行了组织病理学分析。此外,使用RT-PCR和蛋白质印迹法评估尿酸转运蛋白和炎症标志物的基因和蛋白表达水平。结果表明,HD与XOD和尿酸转运蛋白相互作用,显著降低HUA模型中的血清UA水平并抑制XOD活性。它还调节尿酸转运蛋白的表达以增强UA排泄。此外,HD通过降低促炎细胞因子水平并抑制TLR4/Myd88/NF-κB和NLRP3信号通路来保护肝肾功能。这些发现表明,HD可能是一种有前景的治疗剂,可用于降低尿酸并预防与HUA相关的器官损伤。
