Catalog Number: 5479
Alternate Names: CP-456773, MCC 950
Chemical Name: N-[[(1,2,3,5,6,7-Hexahydro-s-indacen-4-yl)amino]carbonyl]-4-(1-hydroxy-1-methylethyl)-2-furansulfonamide sodium salt
Biological Activity
Potent NLRP3 inflammasome inhibitor; inhibits IL-1β (IC50 = 7.2 nM), IL-1α (IC50 = 12-18 nM) and IL-18 (IC50 = 10.3 nM) production. Selective for NLRP3 inflammasome over NLRC4 inflammasome and Toll-like receptor signaling. Inhibits inflammasome activation by soluble and crystalline NLRP3 stimuli. Reduces severity of experimental autoimmune encephalomyelitis, skin inflammation and airway inflammation in mice. Also glutathione S-transferase omega 1 inhibitor. Orally bioavailable.
