Oxypurinol is the active metabolite of allopurinol, which is produced at a rapid rate (half-life of about 1 hour). Two xanthine oxidoreductase enzymes are present in oxypurinol, which has a relatively long elimination half-life (about 23 hours) [1].

| Additional Infomation |
Alloxanthine is a pyrazolopyrimidine compound with the structure 4,5,6,7-tetrahydro-H-pyrazolo[3,4-d]pyrimidine, substituted with oxy groups at positions 4 and 6. It is an EC 1.17.3.2 (xanthine oxidase) inhibitor and also a drug metabolite. Oxopurinol is a metabolite of Alloxanthine and is also a xanthine oxidase inhibitor. Oxopurinol has been reported in starfish (Asterias amurensis), red mussels (Mytilus coruscus), and other organisms with relevant data. It is a xanthine oxidase inhibitor. Drug Indications: Used to treat congestive heart failure and hyperuricemia. Mechanism of Action: Oxopurinol inhibits xanthine oxidase, blocking the conversion of oxopurine. Hypoxanthine and xanthine can be converted to uric acid. Increased oxopurine concentrations, through negative feedback inhibition of xanthine oxidase, reduce uric acid concentrations in blood and urine. Oxopurinol can also promote the incorporation of hypoxanthine and xanthine into DNA and RNA, further reducing serum uric acid concentrations.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.25 mg/mL (8.22 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1.25 mg/mL (8.22 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
