Biological Activity

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

Necrosulfonamide (NSA) is a small molecule that specifically inhibits necroptosis by targeting MLKL, the terminal executioner of necroptosis.

Protocol (from reference)

Cell Assay:

[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.
Animal Study:

[4]
  • Animal Models

    Male Wistar rats

  • Dosages

    1.65 mg/kg

  • Administration

    i.p.
