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 ce
