CP-456773, also known as MCC950 and CRID3, is a potent and selective cytokine release inhibitor and NLRP3 inflammasome inhibitor for the treatment of inflammatory diseases. CP-456773 inhibits interleukin 1β (IL-1β) secretion and caspase 1 processing. MCC950 blocked canonical and noncanonical NLRP3 activation at nanomolar concentrations. MCC950 specifically inhibited activation of NLRP3 but not the AIM2, NLRC4 or NLRP1 inflammasomes. MCC950 reduced interleukin-1β (IL-1β) production in vivo and attenuated the severity of experimental autoimmune encephalomyelitis (EAE), a disease model of multiple sclerosis. MCC950 is a potential therapeutic for NLRP3-associated syndromes, including autoinflammatory and autoimmune diseases, and a tool for further study of the NLRP3 inflammasome in human health and disease.
