designed and synthesized. METHODS Their antioxidant activity was evaluated by detecting the 2-thiobarbituric acid reactive substance (TBARS) produced in the ferrous salt/ascorbate-induced autoxidation of lipids, which were present in microsomal membranes of rat hepatocytes. The lipophilicity of these compounds indicated as partition coefficient between n-octanol and buffer was investigated by ultraviolet
背景技术外源性抗氧化剂被认为是治疗神经退行性疾病的有前途的治疗方法,因为它们可以预防和/或最小化氧化引起的神经元损害。目的设计并合成了基于黄cut苷(2)的结构上的三系列亲脂性化合物,黄re苷(2)是黄cut苷(1)在体内的一种代谢产物。方法通过检测亚铁盐/抗坏血酸诱导的脂质自氧化产生的2-硫代巴比妥酸反应性物质(TBARS)来评估其抗氧化活性,所述脂质存在于大鼠肝细胞的微粒体膜中。用紫外(UV)分光光度计研究了表示为正辛醇和缓冲液之间分配系数的这些化合物的亲脂性。结果该研究表明在C4'-OH位置被苄基取代的化合物5e表现出强的抗氧化活性和良好的亲脂性。结论5e可能是预防或减少与神经退行性过程相关的氧化状态的有效候选者。
