ABSTRACT:
A new class of oligonucleotide N3'.fwdarw.P5' phosphoramidates having 2' fluoro substituents are provided that have superior acid stability. The invention includes oligo-2'-fluoronucleotide N3'.fwdarw.P5' phosphoramidates, methods of synthesis, and duplexes and triplexes formed with DNA and RNA. Compounds of the invention are useful where the formation of stable and specific duplex and/or triplex structures is desired, including antisense and/or anti-gene pharmaceuticals, branched DNA components, DNA and/or RNA capture agents, components of DNA-based diagnostic assays, and the like.
