A series of hydroxylated 3-hydroxycoumarins was synthesised by the reaction of 3-aryl-2-hydroxypropenoic derivatives with boron tribromide. They were evaluated for their ability to scavenge the 2,2-diphenyl-1-picrylhydrazyl radical, the superoxide anion radical, the hydroxyl radical and the peroxynitrite anion and to inhibit copper-induced human LDL peroxidation. The physicochemical results were in
通过3-芳基-2-羟基丙烯酸衍生物与三溴化硼的反应合成了一系列羟基化的3-羟基香豆素。他们评估了它们清除2,2-二苯基-1-吡啶并肼基,超氧阴离子基,羟基和亚硝酸根阴离子以及抑制铜诱导的人LDL过氧化的能力。根据理化结果,确定在C-6和C-7位置上羟基化的化合物是该系列中最活跃的,具有与槲皮素和维生素C相当的抗氧化能力。这些化合物在形成时会形成邻-和对-醌型衍生物清除自由基,可作为药理研究的新先导化合物。
