    摘要: The present invention relates to synthesis, purification and methods to obtain high purity novel 2′-arabino-O-methyl nucleosides and the corresponding phosphoramidites of various arabinonucleoside bases and introduction of such units into defined sequence synthetic DNA and RNA. Various synthetic oligonucleotides, such as HIV integrase inhibitor 14-mer and thrombin binding oligonucleotide, thrombin-1, bearing ara-2′-omethyl modification have been synthesized. It is anticipated the oligonucleotides incorporating these monomers will exhibit biological activities related to antisense approach approach, design of better SiRNA's, diagnostic agents. Similarly, it is anticipated that oligonucleotides incorporating such novel nucleosides will be useful to develop therapeutic candidates designing stable G-quadruplexes and Aptamers for oligonucleotide structure, folding topology, evaluation of biochemical properties and design and develop as therapeutic agents. It is further anticipated that the nucleosides, phosphates and triphosphates of this invention could develop as therapeutic agents.
