Necrostatin-1 (4311-88-0) is an inhibitor of necroptosis (non-apoptotic cell death pathway; EC50 = 494 nM).1 It is an ATP-competitive death domain receptor-associated adaptor kinase (RIP1) inhibitor (EC50 = 182 nM).2 Necrostatin-1 displays a protective effect in a mouse model of ischemic brain injury1, inhibits myocardial cell death and reduces infarct size in various mouse heart models3 and inhibits glutamate-induced oxytosis in HT-22 cells4.
