What is Floxuridine
An antineoplastic antimetabolite that is metabolized to fluorouracil when administered by rapid injection. Floxuridine is available as a sterile, nonpyrogenic, lyophilized powder for reconstitution. When administered by slow, continuous, intra-arterial infusion, it is converted to floxuridine monophosphate. It has been used to treat hepatic metastases of gastrointestinal adenocarcinomas and for palliation in malignant neoplasms of the liver and gastrointestinal tract. (PubChem)
Floxuridine mechanism of action
Floxuridine is rapidly catabolized to 5-fluorouracil, which is the active form of the drug. The primary effect is interference with DNA synthesis and to a lesser extent, inhibition of RNA formation through the drug’s incorporation into RNA, thus leading to the production of fraudulent RNA. Fluorouracil also inhibits uracil riboside phophorylase, which prevents the utilization of preformed uracil in RNA synthesis. As well, the monophosphate of floxuridine, 5-fluoro-2′-deoxyuridine-5′-phosphate (FUDR-MP) inhibits the enzyme thymidylate synthetase. This leads to the inhibition of methylation of deoxyuridylic acid to thymidylic acid, thus interfering with DNA synthesis.
