摘要:
The present invention is directed to novel oligonucleotides with improved antisense properties. The novel oligonucleotides comprise at least one Locked Nucleic Acid (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. The present invention also provides a new class of pharmaceuticals which comprise antisense oligonucleotides and are useful in antisense therapy.
摘要:
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.

摘要:
The present invention relates to large scale preparation of LNA phosphoramidites using a 2-cyanoethyl-N,N,N′,N′-tetra-substituted phosphoramidite and a nucleophilic activator, e.g. 2-cyanoethyl-N,N,N′,N′-tetraisopropylphosphoramidite and 4,5-dicyanoimidazole. The method is faster and more cost efficient that previously known methods.
