Description

General description

Chemical structure: nucleoside

Application

Used in studies on TMP biosynthesis.

Biochem/physiol Actions

Nucleoside analog that has antifungal activities. 5-FC is deaminated by cytosine deaminase to product 5-fluorouracil, resulting in RNA miscoding. 5-Fluorocytosine inhibits DNA and RNA synthesis and interferes with ribosomal protein synthesis.
