Synthesis and antiviral activity of 2-deoxy-1,5-anhydro-D-mannitol nucleosides containing a pyrimidine base moiety
摘要:
Nucleoside analogues containing a 2-deoxy-1,5-anhydro-D-mannitol and a pyrimidine base moiety were synthesized starting from D-glucose via a nucleophilic opening of an epoxide with the heterocyclic base and an inversion of configuration at the 3'-position. Study of the conformation of these molecules, that show some activity against herpesviruses (HSV, VZV, CMV) should increase our understanding of the structural requirements of hexitol nucleosides for antiviral activity.

The present invention is directed to nucleoside analogues with as substitute for the sugar part a 1,5-anhydrohexitol moiety, doexygenated and substituted with a nucleobase at the 2-position, of which the hexitorl ring is further substituted with at least one alkoxy substituent at the 3-position or at the 1-position, and to oligonucleotides wherein at least some of the nucleotides are part of the afore mentioned hexitol nucleoside analogues and exhibit sequence-specific hydridization to complementary sequences of nucleic acids, and maintaining or improving the hybridisation strength. The invention further relates to nucleoside analogues with a 1,5-anhydrohexitol moiety as the sugar part, deoxygenated and substituted with a nucleobase at the 2-position, of which the hexitol ring is substituted with a methoxy substituent at the 1-position, having at the same time either a hydroxy or an alkoxy group at the 3-position, or having a 3-deoxygenated position. The inclusion of one or more of the afore mentioned hexitol nucleoside analogues in oligonucleotides provides, inter alia, either for improved binding or for maintained binding of these oligonucleotides to a complementary strand. This invention further relates to the chemical synthesis of these oligomers which are useful diagnostics, therapeutics and as research agents.

As part of a project concerning the investigation of new hexitol nucleic acids (HNA), the 1,5-anhydro-2-deoxy-D-altritol nucleoside building blacks with a uracil, cytosine, adenine and guanine base moiety were synthesized. The uracil analogue was used for the automated synthesis of corresponding oligonucleotides. Hybridization capabilities of these altritol nucleic acids (ANA) are illustrated by the Tm values obtained for the (a(h)U)(13)/(dA)(13) duplex.
