Necrostatin 2 S enantiomer is primarily utilized in research settings to study and inhibit necroptosis, a form of programmed cell death. It serves as a valuable tool in understanding cellular death pathways and their implications in diseases such as neurodegenerative disorders, ischemic injuries, and inflammatory conditions. By blocking specific signaling pathways involved in necroptosis, it helps researchers explore potential therapeutic strategies for conditions where uncontrolled cell death is a contributing factor. Additionally, it aids in differentiating necroptosis from other cell death mechanisms, such as apoptosis, enhancing the precision of experimental outcomes in cellular and molecular biology studies.
