标题:Synthesis Of A 6-Methyl-7-Deaza Analogue Of Adenosine That Potently Inhibits Replication Of Polio And Dengue Viruses
摘要:Bioisosteric Deaza Analogues Of 6-Methyl-9-Beta-D-Ribofuranosylpurine,A Hydrophobic Analogue Of Adenosine,Were Synthesized And Evaluated For Antiviral Activity. Whereas The 1-Deaza And 3-Deaza Analogues Were Essentially Inactive In Plaque Assays Of Infectivity,A Novel 7-Deaza-6-Methyl-9-Beta-D-Ribofuranosylpurine Analogue,Structurally Related To The Natural Product Tubercidin,Potently Inhibited Replication Of Poliovirus (Pv) In Hela Cells (Ic50 = 11 Nm) And Dengue Virus (Denv) In Vero Cells (Ic50 = 62 Nm). Selectivity Against Pv Over Cytotoxic Effects To Hela Cells Was > 100-Fold After Incubation For 7 H. Mechanistic Studies Of The 5'-Triphosphate Of 7-Deaza-6-Methyl-9-Beta-D-Riboluranosylpurine Revealed That This Compound Is An Efficient Substrate Of Pv Rna-Dependent Rna Polymerase (Rdrp) And Is Incorporated Into Rna Mimicking Both Atp And Gtp.
