Biological Activity

Description Necrosulfonamide is a very specific and potent necrosis inhibitor and blocks mixed lineage kinase domain-like protein (MLKL).
necrosis(MLKL) [1]
In vitro

Necrosulfonamide inhibits MLKL-mediated Necrosis by blocking its N-terminal CC domain function. It blocks necrosis downstream of RIP3 activation. Necrosulfonamide has no effect on apoptosis induced by TNF-α plus Smac mimetic in non-RIP3-expressing Panc-1 cells, even at 5 μM concentration. Necrosulfonamide efficiently blocks necrosis in human cells, but not mouse cells. The reason for the species specificity of necrosulfonamide is that the cysteine at residue 86 in human MLKL that is covalently modified by necrosulfonamide is replaced by a tryptophan residue in mouse MLKL(mixed lineage kinase domain-like protein)[2].

Protocol (from reference)

Cell Research:[3]
  • Cell lines: HT-29 cells
  • Concentrations: 1 μM
  • Incubation Time: 8 or 12 hrs
  • Method: Necrosis inhibitors induce diverse effects on MLKL phosphorylation. HT-29 cells are treated with T/S/Z with or without necrosis inhibitors for 12 hr or 8 hr. The number of dead cells is determined by measuring released protease activity in culture medium. The whole-cell extracts are prepared and analyzed by western blotting. The final concentrations of 10 μM necrostatin-1 or 1 μM necrosulfonamide are used to block necrosis.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
