How It Works

Acyclovir is an antiviral agent that selectively inhibits the replication of herpes simplex virus. It is activated by viral thymidine kinase and then competes with deoxyguanosine triphosphate for incorporation into viral DNA, leading to chain termination and inhibition of viral DNA polymerase.

Mechanism Steps

1
Viral uptake and activation: Acyclovir enters infected cells and is phosphorylated by viral thymidine kinase to acyclovir monophosphate.
2
Conversion to active triphosphate: Cellular kinases convert acyclovir monophosphate to the active triphosphate form, acyclovir triphosphate.
3
Competitive inhibition: Acyclovir triphosphate competes with deoxyguanosine triphosphate for binding to viral DNA polymerase.
4
DNA chain termination: Incorporation of acyclovir triphosphate into viral DNA results in chain termination, halting viral replication.
