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.

Biologische Aktivität
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].

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).
