Free radicals and reactive oxygen species have the potential to damage a wide variety of organic molecules, typically by oxidizing certain moieties. These damaging species can, for example, be produced by an organism as a by-product of cellular respiration or by the reaction of iron(II) and peroxide. The present invention includes methods of using aryl-substituted heterocyclic iron chelating compounds as antioxidants, as well as preventing the reduction of iron(III) to iron(II). In addition, the present invention provides methods of treating conditions such as inflammatory disease, neoplastic disease, and ischemic episodes.
自由基和反应性氧化物具有损坏各种有机分子的潜力,通常通过氧化某些官能团来实现。这些有害的物质可以由生物体作为细胞呼吸的副产品产生,也可以由铁(II)和过氧化物的反应产生。本发明包括使用芳基取代的杂环铁螯合化合物作为抗氧化剂的方法,以及防止铁(III)还原为铁(II)的方法。此外,本发明还提供了治疗炎症性疾病、肿瘤性疾病和缺血发作的方法。
