Acyclovir (Zovirax) and its l-valyl ester prodrug valacyclovir, represent a new generation of antiviral agents, mainly because of the unique mechanism of action. This purine nucleoside is more efficiently phosphorylated by the thymidine kinase-induced virus of the thymidine kinase host. Once activated to the triphosphate form, it is a better substrate and inhibitor of the virus, against the host, DNA polymerase. The binding to the DNA polymerase is irreversible. Once acyclovir is incorporated into the viral DNA the chain's DNA is complete.

Acyclovir (Zovirax) is relatively safe (probenecid makes the drug safer) and is useful against a variety of infections caused by DNA viruses, especially the family Herpesviridae. However, the resistance increases. Acyclovir is not able to eliminate latent infections. It is available as an ophthalmic ointment, a topical ointment and cream theme, an IV of preparation, and various oral formulations. The deoxyacyclovir prodrug is more easily absorbed by the gastrointestinal tract than Acyclovir. Another antiviral analog purine nucleoside is ganciclovir, a synthesis of guanine effective against human cytomegalovirus. Its mechanism of action is similar to that of Acyclovir.
