Description

CORM-3, a carbon monoxide-releasing molecule, attenuates NF-κB p65 nuclear translocation, reduces ROS generation and enhances intracellular glutathione and superoxide dismutase levels. CORM-3 reduces NLRP3 inflammasome activation[1][2][3].

IC50 & Target

NLRP3

 

In Vitro

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].

In Vivo

CORM-3 (4 mg/kg, ip) reduces NLRP3 inflammasome activation and inhibits hyperglycemia-induced inflammation in mice[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

In Vivo:

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.

  • Protocol 1

    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.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (37.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 3.75 mg/mL (12.73 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 3.75 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (37.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
