Floxuridine (5-Fluorouracil 2'-deoxyriboside) is a pyrimidine analog and known as an oncology antimetabolite. Floxuridine inhibits Poly(ADP-Ribose) polymerase and induces DNA damage by activating the ATM and ATR checkpoint signaling pathways in vitro. Floxuridine is a extreamly potent inhibitor for S. aureus infection and induces cell apoptosis. Floxuridine has antiviral effects against HSV and CMV.

Floxuridine inhibits Poly(ADP-Ribose) polymerase and induces DNA damage by activating the ATM and ATR checkpoint signaling pathways in vitro. Floxuridine is a extreamly potent inhibitor for S. aureus infection and induces cell apoptosis[1][2]. Floxuridine has antiviral effects against HSV and CMV[3].

In Vitro

Floxuridine (0-25 μM; 4-24 hours) is affectd by inhibitors of PARP and its sensitivity of ovarian cancer cells is enhanced. Co-exposed to FdUrd and the PARP inhibitor markedly increases killing cell numbers when its compare to treatment alone in ovarian cancer cells[1].
Floxuridine (300 μM; 4-24 hours) increases p-Chk1 and p-Chk2 in ovarian cancer cell lines. It may induce DNA damage and activate the ATM and ATR checkpoint signaling pathways[1].
Floxuridine (0-2.5 μM; 24 hours) causes a G1/S-phase arrest and following removal of the FdUrd, the G1/S-phase-arrested cells moved synchronously through S phase and into G2/M[1].
Floxuridine is also a very potent inhibitor of staphylococcal growth (MIC, 0.025–0.00313 μM)[2].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (8.45 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (8.45 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
