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).

体外実験

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].

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

体内実験

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.

Stock Solution Working Solution

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
