Tegafur and uracil (UFT)
Also known as Ftorafur, Tefudex, Tegafur-uracil, Ufur, and Uftoral.
General information
Class/mechanism: Contains a fixed ratio (4:1) of uracil to tegafur. Tegafur is metabolized in vivo to Fluorouracil (5-FU), which is a pyrimidine analog antimetabolite that is metabolized to 5-fluoro-2'-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP). FdUMP inhibits DNA synthesis by binding to thymidylate synthase and inhibiting production of thymidylate; FUTP interferes with RNA processing when it is mistakenly incorporated in place of uridine triphosphate (UTP). Uracil helps to maintain intracellular levels of Fluorouracil (5-FU) by inhibiting its degradation.[1][2][3]
