Figure 1 Different mechanisms of 5-fluorouracil action. 5-Fluorouracil (5_FU) and its derivative active metabolites exert their antitumor function at the levels of enzyme thymidylate synthase, DNA and RNA, leading to DNA and RNA damage and cell death. TS: Thymidylate synthase; FdUMP: Fluorodeoxyuridine’ monophosphate; FdUDP: Fluorodeoxyuridine diphosphate; FdUTP: Fluorodeoxyuridine triphosphate; FUMP: Fluorouridine monophosphate; FUDP: Fluorouridine diphosphate; FUTP: Fluorouridine triphosphate; CH2THF: 5,10-methylenetetrahydrofolate; dTTP: Deoxythymidine triphosphate; dUMP: Deoxyuridine monophosphate.
