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.

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 addition, 1.25 mg/kg single administration of the compound shows statistically significant protection against S. aureus infection^[2].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
