NLRP3-IN-83 is a selective and orally active NLRP3 inflammasome activation inhibitor. NLRP3-IN-83 exhibits good inhibitory IL-1β activity with an IC50 of 1.4 μM by blocking NLRP3, independent of NF-κB signaling. NLRP3-IN-83 only slightly inhibits AIM2 inflammasome pathway, but has no effect on NLRC4 inflammasome. NLRP3-IN-83 prevent cell pyroptosis and exhibits significant anti-inflammatory efficacy in ulcerative colitis model. NLRP3-IN-83 can be used for the study of inflammatory bowel disease (IBD) [1].
