Necrosulfonamide is a pharmacological inhibitor of MLKL with IC50 values of 124 nM in human HT-29.target: MLKL IC50 : 124 nM.In vitro: Necrosulfonamide significantly decreases BV6/DAC-induced cell death in MV4-11 cells. Treating cells with necrosulfonamide or knocking down MLKL expression arrests necrosis at a specific step at which RIP3 formed discrete punctae in cells. necrosulfonamide had no effect on apoptosis induced by TNF-α plus Smac mimetic in non-RIP3-expressing Panc-1 cells. Complete inhibition was observed at NSA concentration of 0.5 M. NSA is also an effective inhibitor of the necroptotic pathway induced by STS in the presence of caspase inhibitor.
