NLRP3-IN-84 (Compound 32) is a NLRP3 inflammasome inhibitor. NLRP3-IN-84 can interfere with the oligomerization process of NLRP3 by inhibiting the activity of NLRP3 ATPase (IC50 = 158.4 nM). NLRP3-IN-84 inhibits Caspase-1 (IC50 = 27.7 nM), IL-1beta release (PBMC: IC50 = 19.5 nM, mPBMC: IC50 = 24.2 nM), and ASC plaque formation (IC50 = 131 nM). NLRP3-IN-84 has no inhibitory activity on NLRC4 and AIM2 inflammasomes. NLRP3-IN-84 exhibits significant in vivo anti-inflammatory effects in a mouse acute peritonitis model. NLRP3-IN-84 can be used for the study of NLRP3-related inflammatory diseases[1].
