== Publication Abstract from PubMed ==

Locked nucleic acid (LNA) analogues with 2',4'-bridged sugars show promise in antisense applications. S-5'-Me-LNA has high RNA affinity, and modified oligonucleotides show weakened immune stimulation in vivo. Conversely, an R-5'-methyl group dramatically lowers RNA affinity. To test the effects of S- and R-6'-methyl groups on 3'-fluoro hexitol nucleic acid (FHNA) stability, we synthesized S- and R-6'-Me-FHNA thymidine and incorporated them into oligo-2'-deoxynucleotides. As with LNA, S-6'-Me is stabilizing whereas R-6'-Me is destabilizing. Crystal structures of 6'-Me-FHNA-modified DNAs explain the divergent consequences for stability and suggest convergent origins of these effects by S- and R-6'-Me (FHNA) [-5'-Me (LNA and RNA)] substituents.
