WebFlucytosine (Fig. 5.92) is an antimetabolite that enters fungal cells via cytosine permease, where it is converted intracellularly to fluorouracil (5-FU), which acts as a false nucleoside, inhibiting synthesis of both DNA and RNA (Harvey et al., 2009; From: Antifungal Compounds Discovery, 2024 View all Topics Add to Mendeley About this page WebCytosine permease With the aid of cytosine permease, flucytosine reaches the fungal cell where it is converted by cytosine deaminase into 5-fluorouracil [51-21-8]. Cytosine …

WebJul 17, 2006 · A genome-wide search for cytosine permease homologues identified two uncharacterized candidate genes, designated FCY21 and FCY22, both of which exhibit highest similarity to FCY2. Disruption of either FCY21 or FCY22 resulted in strains displaying low-level resistance, indicating the functional involvement of both gene … WebJul 17, 2006 · Abstract. 5-Fluorocytosine (5-FC), a medically applied antifungal agent (Ancotil ® ), is also active against the model organism Saccharomyces cerevisiae. 5-FC … WebFlucytosine is 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 … swansea tourist attractions
