Abstract:
PURPOSE:To obtain the subject derivative useful for treating rheumatoid arthritis, cataract, etc., having uniform electric charge and molecular weight and stable activity by reacting a human Cu, Zn type superoxide dismutase with a specific alkyl disulfide. CONSTITUTION:Human Cu, Zn type superoxide dismutase is mixed with an alkyl disulfide of formula I (X is amino, 1-10C alkyl, amino replaced with 1-10C alkyl or 2-10C acyl group or hydroxyl; R and R are H or 1-IOC alkyl), adjusted to pH 7.0, incorporated with water and reacted at 4 deg.C for 24 hours while stirring to give the objective enzyme derivative of formula II (SOD' is group obtained by removing H from mercapto group of cystine residue at 111st of human Cu, Zn type superoxide dismutase) having uniformity with respect to electronic charge and molecular weight, stable activity, useful as a preventive and a therapeutic agent for rheumatoid arthritis, oxygen retinopathy of immature baby, cataract, etc., in which superoxide exists.
Abstract:
