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.

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.

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
