Used primarily in research to inhibit glutathione synthesis by targeting the enzyme γ-glutamylcysteine synthetase. This inhibition leads to depletion of intracellular glutathione, making cells more susceptible to oxidative stress. Commonly applied in cancer research to sensitize tumor cells to chemotherapy and radiation. Also utilized in studies involving oxidative stress mechanisms, neurodegenerative diseases, and drug resistance in cell cultures. Its ability to modulate redox status makes it a valuable tool in experimental models exploring cellular defense systems.
