poly(4-vinylpyridine), poly(4-vinylpyridine N-oxide), and polystyrene/methylrhenium trioxide systems for the selective oxidation of tocopherols and tocopherol derivatives to the corresponding ortho- and para-tocopherylquinones is described. Environment friendly, easily available, and low-cost hydrogen peroxide (H2O2) was used as the oxygen atom donor. The antiviral activity of the newly synthesized tocopherylquinones
描述了一种方便有效的方法,将异质聚(4-乙烯基吡啶),聚(4-乙烯基吡啶N-氧化物)和聚苯乙烯/甲基r三氧化二体系用于将生育酚和生育酚衍生物选择性氧化为相应的邻-和对-生育酚醌。环保,易于获得且低成本的过氧化氢(H 2 O 2)用作氧原子供体。还报道了新合成的生育酚醌及其母体生育酚对甲型流感病毒的抗病毒活性。在生物学分析的基础上,生育酚对流感病毒的活性高于相应的生育酚醌所显示的活性,因此首次暗示了氧化代谢对这些化合物的抗病毒活性的不利影响。
