ABSTRACT:
The present invention provides nuclease resistant 3'-carbon modified oligonucleotides that can be used in the field of nucleic acid therapeutics and diagnostics. The modified oligonucleotides of the present invention have at least one modified internucleotide linkage wherein the divalent oxygen moiety at the 3'-position of the internucleotide linkage is replaced by a tetravalent carbon moiety. The 3'-carbon modified internucleotide linkage is preferably a 3'-methylene or 3'-hydroxymethylene linkage. Also provided are a method and monomeric nucleoside and nucleotide intermediates for making the modified oligonucleotides of the present invention.
