WebJun 7, 2024 · A fluorinated cytosine analog that is used as an antifungal agent. 5-Fluorocytosine is an antimetabolite that acts as an antifungal agent with in vitro and in vivo activity against Candida and Cryptococcus. 5-Fluorocytosine enters the fungal cell via cytosine permease; thus, flucytosine is metabolized to 5-fluorouracil within fungal … WebFlucytosine is taken up within sensitive fungal cells by cytosine permease, which converts it to 5-fluorouracil. The 5-fluorouracil is then further metabolized to yield 5-fluorodeoxyuridine monophosphate, a competitive inhibitor of thymidylate synthetase. The formation of thymidine monophosphate from deoxyuridine monophosphate is thus blocked ...
