Description: Vidarabine phosphate is an adenosine monophosphate analogue in which ribose is replaced by an arabinose moiety. It is the monophosphate ester of Vidarabinewith antiviral and possibly antineoplastic properties.Vidarabine (Ara-A) is an approved antiviral drug that interfers with the synthesis of viral DNA, and is used to treat herpes simplex and varicella zoster viruses. Vidarabine and Acyclovir have a synergistic effect on wild type . Vidarabine is capable of inhibiting acyclovir-resistant/TK-deficient mutants of HSV and VZV, because it is phosphorylated to its active vidarabine–triphosphate form by cellular kinases and is not dependent for its activation on the viral TK.
