NLRP3-IN-8
NLRP3-IN-8 (compound 27) is an orally active, directly binding NLRP3 inflammasome inhibitor with an IC50 value of 1.23 μM against IL-1 β. NLRP3-IN-8 has good metabolic stability to liver microsomes (t1/2 = 138.63 min), and has almost no toxicity (against L02: IC50 > 100 μM).

In Vitro
NLRP3-IN-8 (compound 27) exhibits prominent anti-inflammatory activity with an IC50 of 1.23 μM[1].
NLRP3-IN-8 exhibits good metabolic stability through human liver microsomes (t1/2 = 138.63 min)[1].
NLRP3-IN-8 (0-10 μM, 1 h) significantly inhibits pyrolysis rate in a concentration-dependent manner[1].
NLRP3-IN-8 only inhibits the activation of NLRP3 inflammasomes, and could inhibit the activation of inflammasome by a variety of inducer[1].
NLRP3-IN-8 blocks NLRP3-induced ASC oligomerization[1].
NLRP3-IN-8 inhibits NLRP3 inflammasome assembly by blocking the interaction of NLRP3-NEK7 and NLRP3-ASC[1].

Cell Line:BMDMs cells
-
Concentration:0.5, 1, and 2 μM
-
Incubation Time:30 min, pretreated with LPS (200 ng/mL) for 3 h
-
Result:Dose-dependently blocked IL-1 b secretion and caspase-1 cleavage at concentrations of 0.5-2 μM. Inhibited the maturation of intracellular caspase-1 (p20), and did not affect the expression of other constituent proteins of NLRP3 inflammasome, such as pro-IL-1 β, pro-caspase-1 (p45), NLRP3, ASC and NEK7.

Animal Model:DSS-induced acute colitis model in C57BL/6 male mice[1].
-
Dosage:20 mg/kg and 10 mg/kg dissolved in 0.5% sodium carboxymethyl cellulose aqueous solution.
-
Administration:Intragastric administration, once a day, 7 days.
-
Result:Reduced the weight loss during the onset of colitis in mice, and decreased the disease activity index (DAI) in a dose-dependent manner. Reduced colon shortening, pathological index score, the expression of TNF-a, IL-6 and IL-1 β in the tissues and inhibited the decrease of goblet cells.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Pyroptosis Solutions
Pyroptosis is a lytic inflammatory cell-death pathway executed by gasdermin pores, most classically through inflammasome-mediated activation of caspase-1, cleavage of gasdermin D, membrane pore formation, LDH release, and secretion of IL-1β and IL-18. The canonical pathway is commonly modeled by priming cells with an inflammatory signal such as LPS to induce pro-IL-1β and inflammasome components, followed by an activation signal such as ATP or nigericin to activate NLRP3, ASC speck formation, caspase-1 cleavage, GSDMD cleavage, cytokine release, and pyroptotic membrane rupture. The non-canonical pathway is triggered when cytosolic LPS activates mouse caspase-11 or human caspase-4/5, leading to GSDMD cleavage and pyroptosis, and this can secondarily activate NLRP3-dependent IL-1β release. Pyroptosis is linked to inflammatory injury, infection, cancer, liver disease, ocular disease, placental inflammation, and other disease phenotypes, but unresolved questions include which gasdermin fam
