An internal standard for the quantification of necrosulfonamide
Necrosulfonamide-d4 is intended for use as an internal standard for the quantification of necrosulfonamide by GC- or LC-MS. Necrosulfonamide is an inhibitor of necroptosis, apoptosis, and pyroptosis.1,2 It inhibits IL-8-induced increases in receptor-interacting serine/threonine kinase 1 (RIPK1), RIPK3, mixed lineage kinase domain-like protein (MLKL), caspase-3, and caspase-8 levels, as well as IL-8-induced necroptosis and apoptosis in isolated human nucleus pulposus cells.1 Necrosulfonamide binds to gasdermin D and inhibits NLRP3- and pyrin-mediated pyroptosis in mouse bone marrow-derived macrophages (BMDMs) when used at a concentration of 5 µM.2 In vivo, necrosulfonamide (20 mg/kg) increases survival in a mouse model of LPS-induced sepsis. It also improves motor function and reduces spinal edema in a mouse model of surgically induced spinal cord injury (SCI).3
