Ulodesine
Based on 1 publication(s) in Google Scholar
Ulodesine is a purine nucleoside phosphorylase (PNP) inhibitor, with an IC50 of 2.293 nM against human PNP, and low nanomolar IC50 values against mouse, rat and monkey PNP. Ulodesine blocks the production of uric acid precursors, reduces serum uric acid levels, clears accumulated uric acid in the blood, and elevates the levels of purine nucleosides including guanosine. Ulodesine reduces the counts of total lymphocytes, T lymphocytes and lymphocyte subsets, inhibits the proliferation of cancer cells and activated lymphocytes, and enhances vaccine immune responses. Ulodesine can be used in research related to hyperuricemia and gout.

Biological Activity
|
PNP 2.293 nM (IC50) |
Ulodesine exhibits potent nanomolar-range inhibitory activity against PNP, with an IC50 of 2.293 nmol/L[1].
Ulodesine (low nM) potently inhibits PNP and blocks proliferation of T-ALL cell lines at low nM concentrations, inhibits activated normal PBLs with lower potency, and has no effect on HUT102 CTCL cells[3].

Solvent & Solubility
DMSO : 25 mg/mL (94.60 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1 mg/mL (3.78 mM); Clear solution
This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1 mg/mL (3.78 mM); Clear solution
