| abstract |
The present invention relates to a composite regulating metabolism, proliferation, differentiation and apoptotic mechanisms and applicable for the treatment for a variety of medical conditions, the composite comprising and oxidized glutathione-based compound, which has a disulfide bond, and a metal material, in particular where the metal is either platinum or palladium. The oxidized glutathione-based compound and metal material can be present in a ratio of 3000 to 1 and preferably 1000 to 1. The oxidized glutathione-based compound can be oxidized glutathione itself or salts or derivatives. A feature of the invention is that the composite has a more stabilized disulfide bond than the oxidized glutathione-based compound itself that significantly enhanced the biological-pharmacological activity of the composite and increased ability thereof for chemical modification resulting in new products possessing new therapeutic effects. Methods for preparing the composite are provided, such methods being beneficial in that the composite is provided in high yields and at high purity. Methods for treating various medical conditions with the composites of the present invention are also disclosed. |
