Vizocross 40%
Vizocross 40% Uses, Dosage, Side Effects, Food Interaction and all others data.
Vizocross 40% is the brand name of Vizocross 40%, a synthetic purine nucleoside with inhibitory activity against herpes simplex virus(HSV-1 & HSV-2) and varicella-zoster virus (VZV). The activity of Vizocross 40% is highly selective due to its affinity for the enzyme thymidine kinase encoded by HSV and VZV. This viral enzyme converts Vizocross 40% into Vizocross 40% monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate and finally triphosphate by a number of cellular enzymes. In vitro, Vizocross 40% 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.
