Abstract
Oligonucleotides with a novel sugar-phosphate backbone containing at least one internucleoside 3′-NHP(O)(S−)O-5′ linkage, and methods of synthesizing and using the inventive oligonucleotides are provided. The inventive thiophosphoramidate oligonucleotides were found to retain the high RNA binding affinity of the parent oligonucleotide N3′→P5′ phosphoramidates and to exhibit a much higher acid stability.
