The present invention provides novel N-alkyl-N-phenylhydroxylamine derivatives containing metal chelating groups, a process for preparing the same, the use of the novel compounds as therapeutics for treating and/or preventing various medical dysfunctions and diseases arising from reactive oxygen species (ROS) and/or excess Zn ions, in particular stroke, Parkinson's disease and Alzheimer's disease. The compounds of the invention possess similar or superior LPO inhibition activity to the reference compounds of Trolox and Ebselen. While showing lower toxicity, they also effectively inhibit the cerebral neuronal cell death caused by ROS and/or zinc ion, and show neuroprotective effects against ischemic neuronal degeneration.
本发明提供了含有金属螯合基团的新型N-烷基-N-苯基羟胺衍生物,以及制备这些化合物的方法,将这些新型化合物用作治疗和/或预防由活性氧化物种(ROS)和/或过量锌离子引起的各种医学功能障碍和疾病,特别是中风、帕金森病和阿尔茨海默病。该发明的化合物具有类似或优越的脂质过氧化抑制活性,相较于Trolox和Ebselen的参考化合物。同时,它们在显示较低毒性的同时,还有效抑制由ROS和/或锌离子引起的脑神经细胞死亡,并对缺血性神经退行性表现出神经保护作用。
