Fialuridine

개요Fialuridine (FIAU) is one of a series of 2'-fluoro-substituted arabinosyl pyrimidine nucleosides that have demonstrated potent antiviral activities against a number of clinically important viruses, including hepatitis B virus (HBV). Analogs of FIAU have been shown to inhibit viral replication in the woodchuck and duck models of HBV infection. Although the mechanism of the anti-HBV activity is not well understood, evidence suggests that the triphosphate analog of FIAU is a potent inhibitor of HBV DNA polymerase activity. During early clinical investigation FIAU showed much promise as an antiHBV drug because it markedly reduced the level of HBV DNA in the serum of patients with chronic hepatitis B. However, clinical trials were terminated after adverse events occurred following oral administration of FIAU (0.1 and 0.25 mg/kg of body weight per day) for more than 2 months. The mechanism of the unexpected delayed toxicity is unresolved.

용도Fialuridine has been used in the selection of clones.

일반 설명Fialuridine (1-(2-deoxy-2-fluoro-β-d-arabinofuranosyl)-5-iodouracil, or FIAU) is an antiviral agent. It is a thymidine-based nucleoside analogue.
