Description

Potassium oxonate (Potassium azaorotate) is a uricase inhibitor that inhibits the phosphorylation of 5-FU to 5-fluorouridine-5'-monophosphate.

In Vivo

Potassium oxonate can be used in animal modeling to create hyperuricemia models. After metabolism, Potassium oxonate primarily distributes within the cells of the small intestine. In the gastrointestinal tract, Potassium oxonate is converted to cyanuric acid via two pathways: the first involves direct conversion by gut microbiota in the cecum, and the second involves conversion through xanthine oxidase, or after degradation by stomach acid into 5-aza-uracil (5-AZU), followed by conversion through aldehyde oxidase[3].

Induction of High Uric Acid[4]
Background
Potassium oxonate is a selective competitive uricase inhibitor that blocks the action of hepatic uricase.
Specific Mmodeling Methods
Mice : Kunming • male • 18-22 g
Administration: 300 mg/kg • i.p. • once daily for 14 days
Note
(1) The animals are adapted to the environment for 1 week before the experiment. All animals have access to a standard diet and water ad libitum and are acclimated to specific pathogen-free (SPF) conditions of 22 ± 2 °C, 60 ± 5% humidity, and a fixed 12-h artificial light period.
(2) On day 15, the mice are fasted for 12 hours, anesthetized with pentobarbital sodium, and then all sacrificed.
(3) Collect mouse blood samples in 2mL EP tubes, centrifuge (3000rpm, 4°C, 10min), and then store at -80°C for biochemical determination.
(4) The kidney tissue is quickly removed, weighed and divided into two parts, one part was fixed in 4% paraformaldehyde for histopathological examination, and the other part is stored at -80°C for further biochemical determination.
Modeling Indicators
Molecular changes: Increased the levels of CRE, BUN, MDA, XOD and UA. Reduced the levels of SOD and GSH-Px in serum. Increased the levels of IL-1β and IL-18 in both serum and kidney and the mRNA expressions of IL-1β, NLRP3, ASC and caspase1.
Histological changes: Inconspicuous boundaries between adjacent proximal tubule cells, swelling and proximal tubule necrosis.
Correlated Product(s): Hypoxanthine (HY-N0091)
Opposite Product(s): Curcumin (HY-N0005)

In Vivo:

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  PBS

    Solubility: 10 mg/mL (51.24 mM); Suspended solution; Need ultrasonic and warming and heat to 60°C

  • Protocol 2

    Add each solvent one by one:  0.5% CMC-Na/saline water

    Solubility: 5 mg/mL (25.62 mM); Suspended solution; Need ultrasonic and warming

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.
