NLRP3-IN-83
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).

NLRP3-IN-83 (Compound 10) (0.625-5 μM, 1-25 h) significantly inhibits IL-1β release in LPS (HY-D1056)-primed J774A.1, LPS -primed murine BMDMs with Nigericin (HY-127019) or SiO2, and a PMA (HY-18739)-differentiated human THP-1 macrophage model in a concentration-dependent manner[1].
NLRP3-IN-83 (1-5 μM, 2 h) significantly reduced the levels of caspase-1 (p20) and IL-1β in the supernatants, while not affecting the expression levels of pro-caspase-1, pro-IL-1β, NLRP3, and ASC in LPS-primed J774A.1 cells[1].
NLRP3-IN-83 (1-5 μM) can prevent cell pyroptosis by inhibiting the cleavage of GSDMD and reducing the release of LDH in LPS-primed J774A.1 cells[1].
NLRP3-IN-83 (2.5-10 μM, 24 h) shows no significant toxicity to J774A.1 macrophages and human embryonic kidney cells HEK-293T[1].
NLRP3-IN-83 (1-5 μM, 2-6 h) inhibits NLRP3 inflammasome activation and has no significant effect on the NF-κB signaling pathway[1].
