  • AMINO-LNA, THIO-LNA AND ALPHA-L-OXY-LN
    Publication number: 20140128586
    Abstract: A novel class of pharmaceuticals which comprises a Locked Nucleic Acid (LNA) which can be used in antisense therapy. These novel oligonucleotides have improved antisense properties. The novel oligonucleotides are composed of at least one LNA selected from beta-D-thio/amino-LNA or alpha-L-oxy/thio/amino-LNA. The oligonucleotides comprising LNA may also include DNA and/or RNA nucleotides.
