Necrosulfonamide Chemical Properties,Usage,Production

Description

Necrosulfonamide (1360614-48-7) specifically blocks necroptosis downstream of RIP3 activation by preventing MLKL-RIP3 interaction.1 Displays neuroprotective effects after ischemic brain injury.2 Prevents cystine-starvation-induced necroptosis and ferroptosis in human triple negative breast cancer cells.3 Binds to gasdermin D inhibiting pyroptosis and associated inflammatory cell death and sepsis.4 Rescues cells from TLR3 ligand-induced death.5

Uses

Necrosulfonamide is a necroptosis inhibitor. Necrosulfonamide is a pharmacological inhibitor of mixed lineage kinase domain-like protein (MLKL).

Definition

ChEBI: Necrosulfonamide is a sulfonamide that is a 3-methoxypyrazin-2-yl derivative of (E)-N-(4-(N-(4,6-dimethylpyrimidin-2-yl)sulfamoyl)phenyl)-3-(5-nitrothiophene-2-yl)acrylamide. Necrosulfonamide specifically blocks necrosis downstream of the activation of RIP3 (the receptor-interacting serine-threonine kinase 3), a key signalling molecule in the programmed necrosis (necroptosis) pathway. It is a sulfonamide, a member of pyrazines and a member of thiophenes.

storage

Store at +4°C
