Used in research for neuroprotection, particularly in the context of ischemic stroke. It was developed to reduce brain damage by scavenging free radicals that are produced during reperfusion injury. Clinical trials focused on its potential to improve neurological outcomes when administered shortly after stroke onset, though results did not show significant efficacy in later phases, leading to discontinuation of development for that indication. Research interest remains in its mechanism as a nitrone-based antioxidant in experimental models of oxidative stress-related conditions.
