NP3-253
Based on 1 Customer Validation
NP3-253 is an orally active and brain-penetranted NLRP3 inflammasome inhibitor. NP3-253 functions as a molecular glue that prevents NACHT-subdomain rearrangements, locking NLRP3 in an inactive conformation. NP3-253 inhibits production of pro-inflammatory cytokines IL-1β and IL-18. NP3-253 can be used for the research of inflammation and neurological disease, suah as peritonitis.

NP3-253 potently inhibits NLRP3-mediated IL-1β secretion in PMA (HY-18739)-differentiated THP-1 cells with an IC50 of 0.5 ± 0.1 nM, and does not inhibit NF-κB-mediated TNF-α secretion[1].
NP3-253 potently inhibits NLRP3-mediated IL-1β secretion in human whole blood with an IC50 of 7 ± 2 nM[1].
NP3-253 does not inhibit NLRC4 inflammasome-mediated IL-1β secretion in NLRC4-overexpressing THP-1 cells at concentrations up to >33 μM, demonstrating inflammasome selectivity[1].
NP3-253 (10 μM; 2 h) has a low efflux ratio of 2.5 in MDCK-MDR1 cells, indicating it is not a strong substrate for human P-glycoprotein[1].
NP3-253 (0.5-25 μM; 10-15 min) does not inhibit human CYP3A4 or CYP2C9 at concentrations up to >25 μM, but potently inhibits CYP2D6 with an IC50 of <0.5 μM[1].
NP3-253 inhibits hERG channel binding with an IC50 of 6.49 μM, suggesting a potential cardiac liability[1].
NP3-253 shows high selectivity across a panel of 29 off-target enzymes, receptors, and ion channels tested up to 10 μM, with only weak binding to muscarinic receptor M2 (IC50 = 9.9 μM) and serotonin transporter 5HTT (IC50 = 3.8 μM)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
NP3-253 (10 mg/kg; p.o.; single dose 22 hours prior to LPS priming) fully inhibits LPS-induced IL-1β production in mouse peritonitis[1].
NP3-253 (20 mg/kg; p.o.; single dose 1 hour prior to LPS injection) completely inhibits LPS-induced IL-18 production in mouse plasma[1].
NP3-253 (0.02-2 mg/kg; p.o.; single dose 1 hour prior to second LPS injection) inhibits LPS-induced IL-1β production in mouse CSF and serum in a dose-dependent manner, with 96.5% inhibition in CSF at 2 mg/kg, and reduces downstream Ccl20 gene expression in brain tissue without affecting Il1b gene expression[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
