Description: Acyclovir monophosphate is the monophosphate ester of Acyclovir. Acyclovir is an antiviral agent with activity against herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella zoster virus. Acyclovir is converted by a herpesvirus enzyme into acyclovir triphosphate that inhibits the synthesis of deoxyribonucleic acid (DNA) molecules in the virally infected cells, thereby inhibiting viral replication. It induces apoptosis in cells transfected with HSV-TK (suicidal gene therapy).
