Abstract

This work demonstrates that spermine is a natural antioxidant and anti-inflammatory agent. It is found that: (1) Spermine inhibits the cytochrome C reduction initiated by FMLP- or PMA-stimulated human granulocytes. (2) Spermine inhibits the Fe(III)/xanthine oxidase stimulated lipid peroxidation of brain phospholipid liposomes. The antioxidative effect disappears at high Fe(III) concentrations. (3) Spermine forms a complex with Fe(II). (4) Spermine inhibits the Fe(II)-induced depolymerization of hyaluronic acid, and EDTA abolishes this effect. (5) Spermine or spermine-Fe(II) has no superoxide mimetic effect. These findings suggest that spermine has at least two antioxidative mechanisms of action: (I) Spermine inhibits the generation of the transport of superoxide radicals from stimulated granulocytes, and (II) Spermine inhibits the Haber-Weiss reaction by forming an unreactive chelate with Fe. Spermine thus prevents generation of destructive hydroxyl radicals.
