Description: Vidarabine (Ara-A; Adenine Arabinoside; 9-β-D-Arabinofuranosyladenine; Arabinofuranosyladenine) is an approved antiviral drug that interfers with the synthesis of viral DNA, and is mainly used to treat HSV and VZV: herpes simplex and varicella zoster viruses. In wild type, acyclovir and vidarabine work in concert. Since cellular kinases phosphorylate vidarabine to its active vidarabine–triphosphate form, which is independent of the viral TK for activation, vidarabine can inhibit acyclovir-resistant/TK-deficient mutants of HSV and VZV.

Calculation Results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
