The invention relates to a process for preparing a conjugate that includes a pentopyranosyl nucleic acid and a biomolecule. The process includes the steps of providing a pentopyranosyl nucleic acid having at least two pentopyranosyl nucleotide subunits that are covalently linked between carbon 4 and carbon 2 of their respective pentopyranosyl rings. The pentopyranosyl nucleic acid also has an electrophilic reactive group. A biomolecule having a nucleophilic reactive group is also provided. The electrophilic reactive group of the pentopyranosyl nucleic acid and the nucleophilic reactive group of the biomolecule are reacted to form a covalent bond.

Process for preparing a pentopyranosyl nucleic acid conjugate

The present invention relates to compositions and methods for suppressing an immune response, e.g., by inhibiting class II MHC-mediated activation of T cells. The subject compounds and methods may be used to treat or prevent disorders such as rheumatoid arthritis and/or multiple sclerosis.

Immunosuppressant compounds, methods and uses related thereto

The invention relates to compounds including at least one pentopyranosyl nucleic acid and a biomolecule conjugated through a covalent linkage to the at least one pentopyranosyl nucleic acid. The pentopyranosyl nucleic acid has at least two pentopyranosyl nucleotide subunits covalently linked between carbon 4 and carbon 2 of their respective pentopyranosyl rings. The pentopyranosyl nucleic acid does not non-covalently bond or hybridize to naturally occurring DNA or RNA. The invention also relates to compounds comprising a biotin molecule and a pentopyranosyl nucleic acid conjugated through a covalent linkage to the biotin molecule. Processes for preparing conjugates are also described.

Pentopyranosyl nucleic acid conjugates

The invention relates to a pentopyranosylnucleoside of the formula (I) or of the formula (II) their preparation and use for the production of a therapeutic, diagnostic and/or electronic component.

Pentopyranosyl nucleic acid arrays, and uses thereof

The present invention relates to a linker nucleoside, its preparation and use for the covalent bonding of biomolecules to oligonucleotides, in particular p-RNA oligonucleotides.
