  • Superoxide dismutase mimic
    Patent number: 5227405
    Abstract: The invention relates to a water-soluble complex formed between a chelating agent and manganese and pharmaceutical compositions thereof. The complex is a low molecular weight mimic of superoxide dismutase. The invention further relates to a method of using the complex comprising treating plant and animal cells with an amount of the complex sufficient to reduce or prevent superoxide radical-induced toxicity.
    Type: Grant
