  Antiviral Oligo- and Polyribonucleotides Containing Selected Triazolo[2,3-a]purines

  摘要：

  Several amphipathic (hydrophobic base, hydrophilic backbone) polyribonucleotides have recently been shown to have potent antiviral activity against HIV and human cytomegalovirus (HCMV). The working hypothesis developed during these studies was that the ability to form an ordered, non-hydrogen-bonded array in solution was an important criterion for activity. To explore further the role of structure and molecular size on the inhibition of virus replication, one new polynucleotide and two 32-mer oligonucleotides based on the triazolo[2,3-a]purine ring system have now been prepared. High-molecular-weight polynucleotide 4a (PTPR) and sulfur-containing 32-mer 5b (TTPR) were moderately active against HIV but showed greater potency against HDMV than ganciclovir. Both 4a and 5b gave clear evidence of cooperative melting behavior, whereas inactive 32-mer 5a showed no such behavior.
