| Research Abstract |
Thisstudy concerns the development and applications of chemical tools that regulate the redox status of cells by designing and synthesizing specific inhibitors of γ-glutamylcysteine synthetase (GCS), therate-determiningenzymeinglutathione synthesis, and γ-glutamyl transpeptidase (GGT), the initial andprimarily important enzyme in the glutathione metabolism.The inhibitors are to serve as chemical probes to investigate the relationships between cell redox potential and various diseases and as leads to agrochemicals and pharmaceuticals, as well as to antiaging cosmetics.
