摘  要：
要:利用分子模拟平台Discovery Studio 4.5研究分析黄腐酸和三七中人参皂苷Rg1分别对蛋白磷酸酯酶2A(Protein phosphatase2A,PP2A)的影响。结果表明,人参皂苷Rg1通过促进PP2A的活性以减少tau蛋白的过度磷酸化,从而防治阿尔茨海默病(Alzheimer disease,AD)。采用CDOCKER对接技术对黄腐酸和人参皂苷Rg1分别与PP2A结合研究表明,黄腐酸也可能与PP2A发生作用,减少tau蛋白的过度磷酸化。与人参皂苷Rg1和PP2A形成的复合物对接结果表明,黄腐酸可能促进人参皂苷Rg1与PP2A的结合,从而增强PP2A的药理活性。

摘  要：
The effects of fulvic acid and ginsenoside Rg1 in notoginsengon respectively acting on protein phosphatase 2(PP2A)were studied by the molecular simulation platform Discovery Studio 4.5.The results showed that ginsenoside Rg1 in notoginseng could promote the activity of PP2A,so as to reduce the hyperphosphorylation of tau protein,in order to prevent Alzheimer disease.Using CDOCKER technology to fulvic acid and ginsenoside Rg1 respectively with PP2A,the combination concluded fulvic acid with PP2A reduce the hyperphosphorylation of tau protein.Ginsenoside Rg1 and PP2A complexes was formed by the docking results analysis.The results of docking with ginsenoside Rg1 and PP2A indicated that fulvic acid could promote the binding of ginsenoside Rg1 to PP2A,thus enhancing the pharmacological activity of PP2A.
