Antiviral Agents

Nucleoside analogs are initially phosphorylated by viral thymidine kinase (TK) to eventually form a nucleoside triphosphate.

Acyclovir (Zovirax)

Synthetic purine nucleoside analogue that inhibits herpes virus replication. Herpes virus TK, but not host cell TK, uses acyclovir as a purine nucleoside, converting it into acyclovir monophosphate, a nucleotide analogue. Guanylate kinase converts the monophosphate form into diphosphate and triphosphate analogues that inhibit viral DNA replication.

Valacyclovir (Valtrex)

Valacyclovir is metabolized to acyclovir and L-valine with better oral absorption than acyclovir.
