Eniluracil
Based on 1 publication(s) in Google Scholar
Eniluracil (5-Ethynyluracil) is an orally active dihydropyrimidine dehydrogenase (DPD) inhibitor. Eniluracil irreversibly inhibits DPD, increases the oral bioavailability of 5-fluorouracil to 100%, and facilitates the uniform absorption and toxicity of 5-fluorouracil. Eniluracil can be used in cancer research of combination with fluoropyrimidines (including 5-fluorouracil). Eniluracil is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Animal Model:Female Fischer 344/HSD rats (6 to 7-week-old; 150-200 g)[1].
-
Dosage:1 mg/kg
-
Administration:Intraperitoneal injection; single daily for 3 days (l h before FUra (5-fluorouracil) and for an additional 2 days after FUra therapy)
-
Result:Produced complete tumor regression that was sustained for at least 90 days posttherapy when combined with 3.5 mg/kg FUra, however, 35 mg/kg FUra alone produced partial responses in 75% of the treated animals ( the tumors regrew in all of these animals).

DMSO : 5.56 mg/mL (40.85 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: ≥ 0.56 mg/mL (4.11 mM); Clear solution
This protocol yields a clear solution of ≥ 0.56 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.6 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: ≥ 0.56 mg/mL (4.11 mM); Clear solution
This protocol yields a clear solution of ≥ 0.56 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.6 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
