Acyclovir is a synthetic antiviral nucleoside analogue. A screening program for antiviral drugs begun at Burroughs Wellcome in the 1960s resulted in the discovery of acyclovir in 1974. Preclinical investigation brought the drug to clinical trials in 1977 and the first form of the drug (topical) was available to physicians in 1982. Activity of acyclovir is greatest against herpes 1 and herpes 2, less against varicella zoster, still less against Epstein-Barr, and very little against cytomegalovirus. Acyclovir is an antiviral agent only after it is phosphorylated in infected cells by a viral-induced thymidine kinase. Acyclovir monophosphate is phosphorylated to diphosphate and triphosphate forms by cellular enzymes in the infected host cell where the drug is concentrated. Acyclovir triphosphate inactivates viral deoxyribonucleic acid polymerase.

In Vitro Use Guide

In uptake studies using valacyclovir, the extraction solution (water/methanol, 50:50) was added to the Caco-2 cells after the uptake period. After standing for 1 h at room temperature, the solutions were centrifuged and the supernatants were filtered. The filtrate was analyzed by highperformance liquid chromatography (HPLC). Valacyclovir showed a marked inhibitory effect (K=440 +/- 29mkM) on [14C]glycylsarcosine uptake via the apical PEPT1.
