Ациклостад
Ациклостад Uses, Dosage, Side Effects, Food Interaction and all others data.
Ациклостад is the brand name of Ациклостад, a synthetic purine nucleoside with inhibitory activity against herpes simplex virus(HSV-1 & HSV-2) and varicella-zoster virus (VZV). The activity of Ациклостад is highly selective due to its affinity for the enzyme thymidine kinase encoded by HSV and VZV. This viral enzyme converts Ациклостад into Ациклостад monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate and finally triphosphate by a number of cellular enzymes. In vitro, Ациклостад triphosphate stops replication of herpes viral DNA. This is accomplished in 3 ways: 1) Competitive inhibition of viral DNA polymerase, 2) Incorporation into and termination of the growing viral DNA chain and 3) Inactivation of the viral DNA polymerase.
