Handling Instructions Technical Support

Citraconic acid (Methylmaleic acid) is an orally active inhibitor targeting the NLRP3 inflammasome and Keap1-Nrf2 pathway. Citraconic acid reduces reactive oxygen species (ROS) generation by inhibiting succinate dehydrogenase (SDH) activity. Citraconic acid also modifies the conformation of Keap1 protein, relieves its inhibition of Nrf2, promotes antioxidant gene expression, and inhibits NLRP3 activation and the release of pro-inflammatory factors such as IL-1β and IL-18. Citraconic acid has anti-inflammatory and antioxidant activities, can reduce oxidative stress and cell pyroptosis, improve tissue damage, and can be used for the research of inflammation-related diseases such as acute renal ischemia-reperfusion injury. Citraconic acid is an isomer of Itaconic acid (HY-Y052).

In Vitro

Hydrogel preparation and enzyme immobilization experiments:
Citraconic acid (molar ratio of acrylamide to 1:3; polymerization reaction time 24 h) can be used to prepare chitosan-polyacrylamide-citraconic acid semi-IPN hydrogels and significantly improve the hydrogel swelling rate (240%-400%). The yield of lipase immobilization in the encapsulation method is high[3].

In Vivo

Citraconic acid (50 mg/kg; intraperitoneal injection; once a day; 3 days) significantly reduces the levels of serum creatinine (Cr), urea (Urea) and cystatin C (Cys-C) in the rat renal ischemia-reperfusion injury model, alleviates renal tubular epithelial cell damage, inflammatory cell infiltration and oxidative stress, and inhibits NLRP3 inflammasome activation and IL-1β and IL-18 release[1].

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

Animal Model: Sprague-Dawley rat renal ischemia-reperfusion injury model (250-300 g，8-10 weeks old)[1]
Dosage: 50 mg/kg
Administration: Intraperitoneal injection, once daily for 3 consecutive days, starting 3 days before ischemia-reperfusion surgery
Result: Significantly improved renal function compared to the ischemia-reperfusion (IRI) group.

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: ≥ 2.5 mg/mL (19.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (19.22 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

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.
