Oxidative stress is implicated, either directly or indirectly, in the pathology of a range of human diseases. As a consequence, the development of efficient antioxidants for medical use has become increasingly important. We have synthesised a range of structurally related organo-sulfur, -selenium and -tellurium agents and demonstrated that a combination of electrochemical methodology, in vitro assays
氧化应激直接或间接地牵涉到一系列人类疾病的病理学中。结果,开发用于医学的有效抗氧化剂变得越来越重要。我们已经合成了一系列结构相关的有机硫,-硒和-碲试剂,并证明了电化学方法,体外测定法和细胞培养试验的组合可用于合理化这些催化剂的抗氧化活性。基于其极低的阳极氧化电位(Epa)和对代表性氧化应激因子叔丁基氢过氧化物和过氧亚硝酸盐的高活性,预计4,4'-二羟基二苯基碲化物是有效的抗氧化剂。该化合物具有较高的活性,IC50值非常低,仅为20 nM,
