Famciclovir: A Prodrug of Penciclovir

Famciclovir is a prodrug of penciclovir [P2164] which is an anti-herpesvirus agent. It has demonstrated inhibitory activity against herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), and varicella zoster virus (VZV). The viral thymidine kinase (TK) phosphorylates penciclovir to a monophosphate form. Subsequently, the monophosphate s converted to penciclovir triphosphate by cellular kinases. The triphosphate inhibits virus DNA polymerase competitively with deoxyguanosine triphosphate. Consequently, famciclovir interfere with herpes viral DNA synthesis and replication. In contrast, human cellular TK have very little ability to add the initial phosphate group to famciclovir (penciclovir), which has extremely low toxicity for human cell.
