    摘要: Nucleic acid analogues provide a particularly useful tool for the preparation of complex polymeric structures of defined geometry because they are relatively stable to reaction conditions for the preparation of such structures and provide the opportunity to introduce reactive groups which would not be possible with usual nucleic acids. These supramolecular structures can be used to form fine networks in nanometer size, for the preparation of e.g., computer chips, new materials/polymers with conductivity and/or insulator properties, and robot arms in nanometer scale.

    摘要: The current invention provides oligonucleotides which comprise a dinucleotide consisting of a 5′ locked nucleic acid (LNA), a phosphorothioate internucleoside linkage bond to a 3′ RNA or RNA analogue. The dinucleotide reduces the strength of hybridization of the oligonucleotide to a complementary nucleic acid target. The modification can be used to modulate hybridisation properties in both single stranded oligonucleotides and in double stranded siRNA complexes, particularly in oligonucleotides where the use of LNA results in excessively strong hybridisation properties.

    摘要: The present invention provides a novel strategy for the synthesis of allofuranose using glucofuranose as starting material in a one-pot reaction. The novel finding is that it is possible to carry out the oxidation of 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose with DMSO/acetic anhydride and a reduction reaction in one pot obtaining high yields of recrystallised and analytical pure 1,2:5,6-di-O-isopropylidene-α-D-allofuranose.
