| Description | Floxuridine (FUDR) is an antimetabolite, floxuridine inhibits thymidylate synthase, resulting in disruption of DNA synthesis and cytotoxicity. |
| In vitro | Floxuridine exhibits higher affinity for PEPT1 than the corresponding 5'-O-mono amino acid ester prodrugs. [1] Floxuridine combined with Leucovorin results in synergistic inhibitory effects on growth of human T-lymphoblast leukemia cells. [2] Floxuridine significantly inhibits the uptake of both [(3)H]-inosine and [(3)H]-adenosine (60-70% of control), while its amino acid ester prodrugs including Val, Phe, Pro, Asp, and Lys esters exhibits markedly decreased inhibition potency (10-30% of control). [3] Floxuridine inhibits cell proliferation by more than 50% relative to the untreated control cells at 36 days, the cell numbers still increases fourfold compared with the initial cell density. Floxuridine results in prolonged effects on the proliferation of human Tenon's capsule fibroblasts in vitro. [4] Floxuridine (FUDR) is an ideal drug for hepatic arterial infusion (HAI) due to its short half life, steep dose response curve, high total body clearance, and high hepatic extraction. [5] |

H2O/DMSO
DMSO
| |||||||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
