VIROLOGY
MECHANISM OF ANTIVIRAL ACTION
Acyclovir is a synthetic purine nucleoside analogue with _in vitro_
and _in vivo_ inhibitory activity against
herpes simplex virus types 1 (HSV-1), 2 (HSV- 2), and varicella-zoster
virus (VZV).
The inhibitory activity of acyclovir is highly selective due to its
affinity for the enzyme thymidine
kinase (TK) encoded by HSV and VZV. This viral enzyme converts
acyclovir into acyclovir
monophosphate, a nucleotide analogue. The monophosphate is further
converted into diphosphate by
cellular guanylate kinase and into triphosphate by a number of
cellular enzymes. _In vitro_, acyclovir
triphosphate s
