GSTO-IN-2 is primarily used in research settings to study the biological functions and mechanisms of glutathione S-transferase omega 1 (GSTO1). It serves as a potent and selective inhibitor of GSTO1, making it a valuable tool for investigating the role of this enzyme in various cellular processes, such as oxidative stress regulation, inflammation, and apoptosis. Researchers utilize GSTO-IN-2 to explore its potential therapeutic applications in diseases where GSTO1 activity is implicated, including neurodegenerative disorders, cancer, and immune-related conditions. Additionally, it aids in understanding the enzyme's involvement in drug metabolism and detoxification pathways, contributing to the development of targeted therapies.
