Pyrazofurin
Based on 3 publication(s) in Google Scholar
Pyrazofurin is an antitumor pyrimidine nucleoside analogue and a orotate-phosphoribosyltransferase inhibitor. Pyrazofurin inhibits cell proliferation and intracellular DNA synthesis by inhibiting uridine 5'-phosphate synthase. Pyrazofurin is also an antibiotic with a broad spectrum of antiviral activity.

Actividad biológica
Pyrazofurin (75 μM; 52 h) inhibits DNA synthesis in guinea pig lymphocytes treated with Canavagin A(HY-P2149), but is reversed by exogenous uridine[1].
Pyrazofurin (0.01-200 μM; 24-96 h) inhibits the growth of head and neck cancer cell lines HEP-2, UMSCC-14B and UMSCC-14C with the IC50 between 0.06 and 0.37 μM, and decreases the levels of intracellular UTP and CTP and increases the levels of ATP and GTP[2].
Pyrazofurin (0.1-100 μM; 72 h) inhibits parainfluenza type 3, measles, vaccinia, and herpes simplex type 2 viruses in Vero cells with the ED50 between 2.8 and 20 μM [3].

Solvente y solubilidad
DMSO : 50 mg/mL (192.89 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 5 mg/mL (19.29 mM; ultrasonic and warming and heat to 60°C)
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 (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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: ≥ 2.5 mg/mL (9.64 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (9.64 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
