Floxuridine: An Antitumor Antimetabolite with Inhibition of Thymidylate Synthase

Floxuridine (FUDR), an antitumor antimetabolite, is a prodrug of 5-fluorouracil (5-FU) [F0151]. Floxuridine is rapidly catabolized to 5-FU in vivo. Similarly to 5-FU, floxuridine inhibits thymidilate synthetase (TS) which is an enzyme that catalyzes the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP). dTMP forms thymidine, a nucleic acid in deoxyribonucleic acid (DNA). Therefore, the primary effect of floxuridine is to interfere with the synthesis of DNA. (The product is for research purpose only.)
