CRID3 sodium salt

Biological Activity

Potent NLRP3 inflammasome inhibitor; closes the active conformation of NLRP3 to the inactive state. Directly interacts with the Walker B motif within the NLRP3 NACHT domain. Inhibits IL-1β, IL-18 and IL-1α production (IC₅₀ values are 7.2, 10.3 and 12-18 nM, respectively). Selective for NLRP3 over NLRC4 inflammasome and Toll-like receptor signaling. Reduces severity of experimental autoimmune encephalomyelitis, skin inflammation and airway inflammation in mice. Also glutathione S-transferase omega 1 inhibitor. Orally bioavailable.
