ACTIONS AND CLINICAL PHARMACOLOGY
Fluorouracil (5-fluorouracil) is a fluorinated pyrimidine
antimetabolite which is structurally
similar to uracil, one of the necessary building blocks in cellular
division and growth.
Figure 1
Its usefulness is based on uracil being utilized preferentially for
nucleic acid biosynthesis in
some tumors. 5-fluorouracil is metabolized to 5-fluorouridine
triphosphate (F-UTP),
2-deoxyfluorouridine monophosphate (Fd-UMP), and 2-deoxyfluorouridine
triphosphate
(Fd-UTP) in cells to concentrations that result in both DNA-directed
and RNA-directed
cytotoxicities (see Figure 1). Fd-UMP is the intracellular cytotoxic
form of 5-fluorouracil. It
competes with the natural substrate d-UMP (deoxyuridine monophosphate)
for the catalytic site

on thymidylate synthetase (a key enzyme in DNA synthesis), forming a
covalent complex with
the enzyme that is unable to undergo the normal catalytic reaction of
converting d-UMP to
d-TMP. The presence of a reduced folate cofactor is required for tight
binding of Fd-UMP to
thymidylate synthetase. Folinic acid (leucovorin), which is
metabolized to 5,10-methylene-
tetrahydropteroylglutamine (a reduced folate), is able to modulate the
ant
