Fialuridine (FIAU): A Thymidine Nucleoside Analog with Activity against Herpes Viruses and Hepatitis B Virus (HBV)

Fialuridine (FIAU) is a thymidine nucleoside analog with activity against various herpes viruses and hepatitis B virus (HBV). FIAU blocks the action of DNA polymerases, thus inhibiting viral replication. FIAU owes its effect to preferential phosphorylation by virus-encoded thymidine kinase to its 5'-diphosphate form. After further conversion to triphosphate form, it acts as an inhibitor or alternate substrate for the viral DNA polymerase. On the other hand, it appear that FIAU causes mitochondrial toxicity leading to fatal liver failure alongside lactic acidosis. (The product is for research purpose only.)
