Acyclic Sugar Analogs of Triciribine: Lack of Antiviral and Antiproliferative Activity Correlate with Low Intracellular Phosphorylation

Abstract

Triciribine and triciribine monophosphate have antiviral and antiproliferative activity at low or submicromolar concentrations. In an effort to improve and better understand this activity, we have synthesized a series of acyclic analogs and evaluated them for activity against select viruses and cancer cell lines. We conclude that the rigid ribosyl ring system of triciribine must be intact in order to be phosphorylated and to obtain significant antiviral and antiproliferative activity.
