NCIt definition : A pyrimidine compound and a fluorinated cytosine analog exhibiting antifungal activity.
After penetration into the fungal cells, flucytosine is deaminated to its active metabolite
5-fluorouracil. 5-fluorouracil replaces uracil during fungal RNA synthesis, thereby
inhibiting fungal protein synthesis. In addition, fluorouracil is further metabolized
to 5-fluorodeoxyuridylic acid monophosphate, which inhibits thymidylate synthetase,
thereby interrupting nucleotide metabolism, DNA synthesis and ultimately protein synthesis.;
Alternative definition : NCI-GLOSS: A drug that treats infections caused by fungi.;
