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.
