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. Necrosulfonamide significantly decreases BV6/DAC-induced cell death in MV4-11 cells. Necrosulfonamide is also an effective inhibitor of the necroptotic pathway induced by STS in the presence of caspase inhibitor.

| Cell lines | HaCaT cells |
| Preparation method | For therapy, necrosulfonamide (NSA) was applied in different concentrations (1, 5 and 10 μM) 1 h after SM exposure. The medium was not removed during the experiment procedure. DMSO served as solvent and was added to the THP-medium for the sham-treated wells in equivalent amounts. After NSA therapy, cells were incubated for another 24 h under before mentioned conditions. |
