|Description||Vidarabine is an antiviral drug by interfering with the synthesis of viral DNA, 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.  Vidarabine and acyclovir (ACV) alone show a concentration-dependent inhibition of plaque formation of HSV-1 in Vero cells. Vidarabine combined with acidic protein bound polysaccharide (APBP) show synergistic effects on the plaque formation of HSV-1 in Vero cells.  Vidarabine acts directly on the DNA polymerase of varicella-zoster virus (VZV) and double-strand DNA viruses, including human adenoviruses. Vidarabine specifically inhibits adenovirus type 11 replication without obvious cytotoxicity in vitro. Vidarabine acts less on the synthesis of early proteins but rather on those after DNA replication.  Vidarabine is an antiviral drug with activity against herpes viruses, poxviruses, and certain rhabdoviruses, hepadnarviruses, and RNA tumor viruses. Vidarabine also is active against vaccinia virus both in vitro and in vivo. 
|In vivo||Vidarabine is rapidly deaminated to 9-β-D-arabinofuranosyl hypoxanthine (Ara-Hx) as the principal metabolite. |
|In vitro||DMSO||53 mg/mL (198.32 mM)|
|Water||3 mg/mL (11.22 mM)|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
