Application

Famciclovir is used in herpes virus infections and hepatitis B drug development research. It may be used as a reference compound. Famciclovir may be used to study the factors that control its conversion into penciclovir and other metabolites.

Biochem/physiol Actions

Famciclovir is an antiretroviral guanosine analog used to treat herpesvirus infections and hepatitis B. Famciclovir is rapidly converted to penciclovir. Viral thymidine kinase phosphorylates penciclovir to a monophosphate form that celular kinases convert in turn to penciclovir triphosphate. Penciclovir triphosphate competitively inhibits viral DNA polymerase and thus viral replication. Prolonged administration can lead to resistance; it is often manifested as selection of pre-existing resistant strains with mutations in the reverse transcriptase domain of the DNA polymerase gene.
