Floxuridine (5-fluorodeoxyuridine) is an oncology drug that belongs to the class known as antimetabolites with an GI50 of 5.1 μM for the inhibition of PEPT1. IC50 value: Target: Nucleoside antimetabolite/analogFloxuridine (Fludara) is a prodrug of floxuridine and an oncology agent with an GI50 of 5.1 μM for the inhibition of MDCK/PEPT1. Floxuridine (Fludara) belongs to the class known as antimetabolites. Floxuridine (Fludara) is most often used in the treatment of colorectal cancer. Floxuridine, an analog of 5-fluorouracil, is a fluorinated pyrimidine. Floxuridine (Fludara) works because it is broken down by the body into its active form, which is the same as a metabolite of 5-Fluorouracil [1]. FdUrd induced an immediate increase in tumor uptake of 5-[(125)I]iodo-2'-deoxyuridine, that vanished after 6 h, as also confirmed by flow cytometry. Biodistribution measurements showed that FdUrd pretreatment increased [(18)F]FLT uptake in all tumors by factors of 3.2 to 7.8 compared with controls, while [(18)F]FDG tumor uptake was about fourfold and sixfold lower in breast cancers and lymphoma. Dynamic PET in FdUrd pretreated mice showed that [(18)F]FLT uptake in all tumors increased steadily up to 1.5 h. MRI showed a well-vascularized homogenous lymphoma with high [(18)F]FLT uptake, while in breast cancer, a central necrosis shown by MRI was inactive in PET, consistent with the histomorphological analysis [2].Clinical indications: Colorectal tumor; Liver tumorFDA Approved Date: December 1970

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
