FLUO 20 |
| The use of nucleosides and nucleoside analogues as therapeutic agents has a long and prosperous history in anticancer and antiviral drug discovery. Recently, several groups have synthesized nucleosides containing modified sugar ring scaffolds that bias the furanose conformation to assume either a North (A-DNA like) or South (B-DNA like) ring pucker. We have prepared several of these analogues that contain a fluorine atom in the ring and studied their structures with both NMR (1H and 19F) and ab initio calculations. We sought to define the precise roles played by the highly electronegative fluorine atoms in defining specific sugar conformations. The talk will highlight recent progress in this area and discuss the therapeutic consequences of fluorine substitution into nucleoside monomers and oligomers. |
