Acyclovir, 9-[2-(hydroxyethoxy)methyl]-9H-guanine (Zovirax),is the most effective of a series of acyclic nucleosidesthat possess antiviral activity. In contrast with true nucleosidesthat have a ribose or a deoxyribose sugar attached to apurine or a pyrimidine base, the group attached to the basein acyclovir is similar to an open chain sugar, albeit lackingin hydroxyl groups. The clinically useful antiviral spectrumof acyclovir is limited to herpesviruses. It is most active (invitro) against HSV type 1, about two times less against HSVtype 2, and 10 times less potent against varicella-zostervirus (VZV).
