Biological Activity
|
NLRP3 |
CORM-3 suppresses caspase-1 activation and the secretion of interleukin (IL)-1β and IL-18 in macrophages in response to lipopolysaccharide (LPS) and ATP. CORM-3 inhibits the oligomerization of the adaptor protein apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), which is required for NLRP3-dependent caspase-1 activation[2].

Animal Model:WT mice (C57BL/6J male, 8e10 weeks old)[2].
-
Dosage:4 mg/kg.
-
Administration:IP for 3 h before i.p. injection of E. coli LPS (10 mg/kg), and IP injection after 7-day-treatment of S0130.
-
Result:Resulted in significantly lower plasma levels of IL-1β and IL-18 in response to LPS challenge in vivo in WT mice relative to that in vehicle-treated control mice, whereas TNF-a levels were unchanged.
Had lower expression of cleaved caspase-1 and cleaved IL-1b in response to ATP and nigericin, relative to vehicle control, whereas the expression of procaspase-1 and pro-IL-1β expression was unchanged.

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
Solubility: 3.75 mg/mL (12.73 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 3.75 mg/mL.
