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).

In Vitro
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].

-
Cell Line:LPS-primed J774A.1 cells
-
Concentration:LPS-primed J774A.1 cells
-
Incubation Time:1 h and stimulated with Nigericin for 1 h
-
Result:Reduced the production of caspase-1 (p20) and decreased the level of mature IL-1β (p17).
Did not affect the expression levels of pro-caspase-1, pro-IL-1β, NLRP3 and ASC.
Inhibited the self-oligomerization process of NLRP3.
Reduced the binding of NLRP3 to the adaptor protein ASC.
Significantly inhibited the formation of ASC oligomers.
In Vivo

-
Animal Model:DSS-induced ulcerative colitis model established in 6-8-week-old C57BL/6 mice[1]
-
Dosage:10 and 20 mg/kg
-
Administration:Intragastric administration (i.g.), once daily for 7 days
-
Result:Significantly improved symptoms of weight loss and rectal bleeding and shortening.
