Three beta,gamma-modified alpha-l-threofuranosyl nucleoside triphosphates were synthesized. The beta,gamma-modified tTTPs undergo a single incorporation event with HIV RT but undergo multiple incorporations to form full-length product with engineered thermophilic polymerases.

polymers composed of TNA (α-l-threofuranosyl-(3′,2′) nucleicacid). This property, coupled with enhanced nuclease stability relative to natural DNA and RNA, warrants further investigation into the structural and functional properties of TNA as an artificial genetic polymer for synthetic biology. Here, we report a highly optimized chemical synthesis protocol for constructing multigram quantities of TNA
A TNA loop modified primer pair was designed to construct a stable terminal-closed linear gene, which can be used as an efficient gene expression system in eukaryotic cells.

A new synthesis route to a-L-threose nucleoside phosphonates via 2-O and 3-O selectively protected L-threose is developed. The key intermediates 2-O-benzoyl-L-threonolactone and 1-O-acetyl-2-O-benzoyl-3-O-t-butyldiphenylsilyl-L-threofuranose were functionalized to synthesize 2'-deoxy-2'-fluoro- and 3'-C-ethynyl L-threose 3'-O-phosphonate nucleosides. The key intermediates developed are important intermediates for the synthesis of new L-threose-based nucleoside analogues, TNA phosphoramidites, and TNA triphosphates.

The present invention relates to novel pro-drugs of L-2′-deoxythreose nucleoside phosphonates, such as phosphoramidate, phosphorodiamidate and phospho-diester pro-drugs. The invention also relates to a process for preparing these novel prodrugs of nucleoside phosphonates. The invention also relates to the use of these novel phosphonate-modified nucleosides to treat or prevent viral infections and their use to manufacture a medicine to treat or prevent viral infections, particularly infections with viruses belonging to the HBV family.
