Synthetic nucleic acid analogues with a conformationally restricted sugar-phosphate backbone are widely used in antisense strategies for biomedical and biochemical applications. The modified backbone protects the oligonucleotides against degradation within the living cell, which allows them to form stable duplexes with sequences in target mRNAs with the aim of arresting their translation. The biologically most active antisense oligonucleotides also trigger cleavage of the target RNA through activation of endogenous RNase H. Systematic studies of synthetic oligonucleotides have also been conducted to delineate the origin of the chirality of DNA and RNA that are both composed of D-nucleosides.
