Acyclovir Mechanism Of Action

Mechanism of action acyclovir (9[2-hydroxymethyl]guanine) is a nucleoside analog that selectively inhibits the replication of herpes simplex virus types 1 and 2 (hsv-1, hsv-2) and varicella-zoster virus (vzv). after intracellular uptake, it is converted to acyclovir monophosphate by virally-encoded thymidine kinase.
