The present invention provides the use of ATG in the preparation of a reagent for adjusting the activity of PP2A; and the use of ATG in increasing the activity of PP2A in 293T cells. The present invention also provides the use of the arctigenin in the preparation of the medicine for reducing the proteinuria of the diabetic mice. The present invention also provides the use of the arctigenin in the preparation of the reagent for inhibiting the expression of the NOX4 gene. The present invention also provides analogues of arctigenin and application thereof. The present invention provides a novel use of ATG for modulating PP2A activity, and ATG can also significantly reduce proteinuria in diabetic mice. At the same time, arctigenin could significantly inhibit the expression of NOX4 in STZ-eNOS
−/−
mice glomeruli. The ATG analogues of the present invention are more effective than the native ATG.
本发明提供了在制备用于调节PP2A活性的试剂时使用ATG的方法;以及在增加293T细胞中PP2A活性时使用ATG的方法。本发明还提供了在制备用于降低糖尿病小鼠蛋白尿的药物中使用
牛蒡苷的方法。本发明还提供了在制备抑制NOX4
基因表达的试剂中使用
牛蒡苷的方法。本发明还提供了
牛蒡苷的类似物及其应用。本发明提供了ATG用于调节PP2A活性的新用途,ATG还可以显著减少糖尿病小鼠的蛋白尿。同时,
牛蒡苷可以显著抑制STZ-eNOS−/−小鼠的肾小球中NOX4的表达。本发明的ATG类似物比原生ATG更有效。
