(E/Z)-Necrosulfonamide is a racemic compound of Necrosulfonamide (HY-100573). Necrosulfonamide is a necroptosis inhibitor acting by selectively targeting the mixed lineage kinase domain-like protein (MLKL). Necrosulfonamide prevents MLKL-RIP1-RIP3 necrosome complex from interacting with its downstream effectors. MLKL is a critical substrate of RIP3 during the induction of necrosis[1][2].
