S1QEL is primarily used in research settings to study mitochondrial function and its role in various diseases. It specifically targets and inhibits the superoxide production at mitochondrial complex I, which is crucial for understanding oxidative stress mechanisms. This makes it a valuable tool in exploring conditions like neurodegenerative diseases, ischemia-reperfusion injury, and aging. By reducing oxidative damage, S1QEL helps researchers investigate potential therapeutic strategies for mitigating mitochondrial dysfunction. Its application extends to pharmacological studies aimed at developing treatments for diseases linked to excessive reactive oxygen species (ROS) production.
