MNP2 is a NLRP3-ASC interaction inhibitor. MNP2 selectively binds to the PYD domain of ASC (Ka=149 nM) and blocks ASC-PYM binding (Ka=58 nM), thereby inhibiting the interaction between ASC and NLRP3 and suppressing the formation of the NLRP3 inflammasome. MNP2 inhibits IL-1beta release and caspase-1 maturation, and reduces the efflux of potassium and chloride ions. MNP2 prevents mitochondrial damage and reactive oxygen species production, and significantly decreases NLRP3 inflammasome formation in neurodegenerative pathologies induced by beta-amyloid, Tau protein and alpha-synuclein. MNP2 is applicable for the research of neurodegenerative diseases[1].
