Vidarabine: An Arabinosyladenine with Ant-Virus and Anti-Cancer Activities

Vidarabine (arabinosyladenine, ara-A) is a synthetic purine nucleoside, and was first synthesized by Lee et al. in 1960. Vidarabine was originally intended as an anti-cancer agent, while the anti-viral activity against herpesvirus and vaccinia virus was reported by Rudder et al in 1965. And also the activity against varicella-zoster virus was reported by Miller et al. in 1968. Vidarabine had a broad-spectrum activity against DNA viruses but little activity against RNA viruses. Vidarabine is converted to the active form vidarabine triphosphate (ara-ATP) which inhibits viral DNA polymerase activity in vitro and in vivo. (The product is for research purpose only.)
