中药活性成分降尿酸作用机制研究进展

摘要

高尿酸血症是由嘌呤类物质代谢紊乱和(或)尿酸排泄减少引起血尿酸增高的一组异质性疾病.中药治疗高尿酸血症的研究逐步受到关注,并取得明显进展.近年来大量实验研究表明,黄酮、皂苷、生物碱等多种中药活性成分通过抑制腺苷脱氨酶和(或)黄嘌呤氧化酶的活性减少尿酸生成,或通过调控尿酸转运蛋白的表达增加尿酸排泄,从而发挥降尿酸的药理作用.该文以高尿酸血症的发病机制为基础,对中药活性成分降尿酸的作用机制研究进行总结,综述近年的研究报道.%Hyperuricemia is a heterogeneous group of diseases caused by disorders of purine metabolism and /or excretion of uric acid reduction .Chinese medicine treatment of hyperurice-mia has gradually attracted attention , and made significant pro-gress.In recent years a large number of experimental studies have shown that flavonoids , saponins , alkaloids and other active components of traditional Chinese medicine can reduce uric acid by inhibiting the activity of key enzymes in purine metabolism ,or by increasing the excretion of uric acid through regulating the expression of uric acid transporters , thereby playing an important role in reducing uric acid .Based on the pathogenesis of hyperu-ricemia, the mechanism of active components of traditional Chi-nese medicine for reducing uric acid is summarized , and recent research reports are reviewed .
