Antiviral activity ацикловира объясняется его
the ability to inhibit the synthesis of virus DNA, i.e. due to
suppression of replication of drug-sensitive viral particles.
Genetic apparatus – nucleic acids DNA and RNA are
complex compounds with nitrogenous bases included in them.
Each individual has its own sequence of nitrogenous
Nitrogenous bases when combined with carbohydrates (deoxyribose
and ribose) form nucleosides. One of them, called thymidine,
is activated in deoxythymidine by the action of the enzyme thymidine kinase.
Deoxythymidine is incorporated into the chain of replicated DNA. Acyclovir
being a synthetic substance, similar in structure to thymidine.
As a result, it interacts with the enzyme
thymidine kinase, turning into mono-, di- and triphosphate. Exactly
Acyclovir triphosphate is able to integrate into a chain of replicated
DNA and cause its damage. At the same time oppression occurs.
viral DNA polymerase, viral synthesis is violated and viral
the particle does not multiply.
Clinically, the effect of acyclovir is manifested by stopping.
