Biological Activity for Necrosulfonamide

Necrosulfonamide is a necroptosis inhibitor. Blocks mixed lineage kinase domain-like protein (MLKL), a critical substrate of receptor-interacting serine-threonine kinase 3 (RIP3) during necrosis. Prevents MLKL-RIP1-RIP3 necrosome complex from interacting with downstream necrosis effectors. Binds and inhibits gasdermin D. Inhibits pyroptosis.

Necrosulfonamide work well to block pyroptosis.
By Xiaogang Wang on 06/12/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: THP-1 cell line

We used Necrosulfonamide as a positive control to inhibit the induction of pyroptosis by staphylococcal cytolysin. Differentiated THP-1 cells were pretreated with 25uM Necrosulfonamide (NSA) for 1 h before treating with or without 1 ug/ml Staphylococcal pore-forming toxin for 4 h. The LDH release in culture supernatants of treated cells was measured. Our data indicated that Necrosulfonamide treatment can significantly inhibit staphylococcal cytolysin induced pyroptosis.
