Alpha-LNA (alpha-D-configured locked nucleic acid).
Two pyrimidine alpha-LNA nucleoside monomers have been synthesised and incorporated into alpha-configured oligonucleotides. A fully modified mixed alpha-LNA sequence displays unprecedented parallel stranded hybridisation with complementary RNA and a remarkable selectivity for RNA over DNA. Modelling shows alpha-LNA:RNA to form an extended duplex with a very broad major groove.
