  α-l-RNA (α-l-ribo Configured RNA): Synthesis and RNA-Selective Hybridization of α-l-RNA/α-l-LNA Chimera

  摘要：

  Synthesis of the novel a-L-ribofuranosyl phosphoramidite derivative 7 was accomplished via the alpha-L-ribofuranosyl thymine nucleoside 4. Amidite 7 was used in automated syntheses of chimeric oligonucleotides composed of mixtures of the novel alpha-L-RNA nucleotide monomer (T-alphaL, alpha-L-ribo configured RNA), and DNA, LNA (T-L, locked nucleic acid) or alpha-L-LNA (T-alphaL(T), alpha-L-ribo configured locked nucleic acid) nucleotide monomers. For alpha-L-RNA/DNA and alpha-L-RNA/alpha-L-LNA chimeras, RNA-selective hybridization was obtained, for alpha-L-RNA/alpha-L-LNA chimera we found increased binding affinity compared to the corresponding DNA:RNA reference duplex. In addition, alpha-L-RNA/alpha-L-LNA chimera displayed significant stabilization towards 3'-exonucleolytic degradation. These, results indicate that alpha-L-RNA/alpha-L-LNA chimeras deserve further evaluation as antisense molecules. (C) 2002 Elsevier Science Ltd. All rights reserved.
