背景

Ki: 0.14 and 0.95 μM for herpes simplex virus types 1 and 2, respectively

Fialuridine is a nucleoside analog with antiviral activity.

Nucleoside analogues mimic physiological nucleosides in terms of uptake and metabolism and are incorporated into newly synthesized DNA resulting in synthesis inhibition and chain termination.

In vitro: Previous in-vitro data showed that 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-ethyluracil (FEAU) had activity against herpes simplex virus types 1 and 2 comparable to that of 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-methyluracil (FMAU), fialuridine (FIAU), and acyclovir (ACV). The cellular toxicity of FEAU was found to be much lower than that of FIAU. Biochemical experiments indicated that FEAU had similar affinity toward thymidine kinases encoded by HSV 1 and 2 and a much lower affinity for cellular thymidine kinase than thymidine [1].

In vivo: The in-vivo antiviral efficiency of FEAU was compared with that of FIAU and ACV by using the herpes encephalitis mode. Moreover, ACV and FEAU could significantly increase the number of survivors at doses of 50 and 100 mg/kg per day, respectively, and FIAU showed significant activity at 25 mg/kg per day in the animal model [1].

Clinical trial: In patients with chronic hepatitis B, fialuridine treatment induced a severe toxic reaction demonstrated by hepatic failure, lactic acidosis, pancreatitis, neuropathy, as well as myopathy. Such toxic reaction was probably caused by widespread mitochondrial damage and [2].
