Estimating the term…
A double- or single-stranded oligonucleotide comprising one or more respectively inter- or intra-oligonucleotide covalent cross-linkages, wherein the or each covalent linkage consists of an amide bond between a primary amine group of one strand and a carboxyl group of the other strand or the same strand, respectively, said primary amine group being directly substituted in the 2′ position of the strand nucleotide monosaccharide ring, and said carboxyl group being carried by an aliphatic spacer group substituted on a nucleotide or nucleotide analog of the other strand or the same strand, respectively. A method for preparing such oligonucleotides, and nucleotide or non-nucleotide synthons useful for preparing an oligonucleotide of the above kind, are also disclosed.
Double-stranded or single-stranded oligonucleotide containing one or more inter- or intra-oligonucleotide covalent crosslink, respectively, characterized in that the or each covalent crosslink consists of an amide linkage between a primary amine group of one strand and a carboxyl group of the other strand or of the same strand, respectively, said primary amine group being substituted directly at the 2′ position of the saccharide ring of a nucleotide of one strand, and said carboxyl group being carried by an aliphatic spacer group substituted on a nucleotide or a non-nucleotide insert of the other strand or of the same strand, respectively.
