  Resistance towards exonucleases of dinucleotides with stereochemically altered internucleotide phosphate bonds

  摘要：

  Kinetic constants for the hydrolytic susceptibility of the internucleotide phosphate bond in normal dinucleotides [e.g., 2'-deoxycytidylyl-(3' > 5')-2'-deoxyuridine (dCpdU) and 2'-deoxyadenylyl-(3'--> 5')-2-deoxycytidine (dApdC)] and isomeric dinucleotides [e.g., 2-deoxycytidylyl-(3' --> 5')-1'-deoxy-2-isouridine (dCpisodU) and 1'-deoxy-2'-isoadenylyl-(3' --> 5')-2-deoxycytidine (isodApdC)], toward 5'- and 3'-exonucleases, phosphodiesterase I (PDE I) and phosphodiesterase II (PDE II) were experimentally determined and remarkable differences emerged. The study is of importance in the discovery of nuclease-stable inhibitors of HIV integrase, but may also have ramifications in the area of anti-sense oligonucleotides of therapeutic interest.

  Discovery of a nuclease-resistant, non-natural dinucleotide that inhibits HIV-1 integrase

  摘要：

  Integration of HIV viral DNA into human chromosomal DNA catalyzed by HIV integrase is essential for the replication of HIV. Discovery of novel inhibitors of HIV integrase is of considerable significance in approaches to the development of therapeutic agents against AIDS. We have synthesized a new dinucleotide 1 with an internucleotide phosphate bond that is unusually resistant to exonucleases. This compound exhibits potent anti-HIV-1 integrase activity.
