摘要:
This application discloses novel phosphoramidate and phosphonoamidate prodrugs of nucleosides, nucleotides, C-nucleosides, C-nucleotides, phosphonates, and other alcohol-containing drugs; use of these prodrugs for treatment of infectious diseases and cancers, in particular, liver infections and cancers; and methods of preparing these novel phosphoramidate and phosphonoamidate prodrugs.
摘要:
The subject of the invention is a new method of the synthesis of polyphosphate analogues, such as nucleosides, oligonucleotides, carbohydrates, peptides and proteins, which are of biological importance and are used in organic chemistry, molecular biology and biotechnology. Polyphosphate analogues, including in particular nucleoside 5′-triphosphates, display high biological activity and are responsible for the provision and storage of energy in live organisms. The method relates to the synthesis of organic polyphosphates of general formula (1), where n has a value of 0 to 2, while X stands for an organic radical, in particular nucleoside, oligonucleotide, peptide-carbohydrate or a protein radical.

The present invention also relates to processes for preparing said compounds, pharmaceutical compositions containing them and their use, alone or in combination with other HCV inhibitors, in HCV therapy.
摘要:
The present invention relates to compounds and their use in competitive protein binding assays, for example for use with glycosyl transferase and/or glycoprocessing proteins. The present application also provides kits and apparatuses for use in the assays. In particular, the present invention provides a compound of the formula (I): wherein n is 1, 2 or 3; R1 is selected from —OH, —OPO3H, —OR4, —NHR4, R6; R2 and R3 are each independently selected from —H, —OH, optionally substituted —O-alkyl and —O-alkanoyl; R4 is selected from an optionally substituted mono or polysaccharide, -alkyl, -alkenyl, -alkynyl, and L-Z, where L is a linking agent and Z is a binding agent; R6 is an optionally substituted hydrocarbon group; A is either (i) a substituted heteroaryl group, the substituent on the heteroaryl group having a double bond conjugated to the heteroaryl group, or (ii) a substituted aryl group, the substituent on the aryl group having a double bond conjugated to the aryl group.
摘要:
This invention relates to antisense oligonucleotides comprising at least one N3′→P5′ phosphorodiamidate linkage (NPN) in the backbone as well as methods for using the same. The antisense oligonucleotides can effectively prevent or decrease protein expression.
摘要:
The present disclosure describes tetrahydropyran nucleoside analogs, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, tetrahydropyran nucleoside analogs are provided, having one or more chiral substituents, that are useful for enhancing properties of oligomeric compounds including nuclease resistance and binding affinity. In some embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
摘要:
The present disclosure relates to new polymethine compounds and their use as fluorescent labels. The compounds may be used as fluorescent labels for nucleotides in nucleic acid sequencing applications.
摘要:
The present disclosure provides tricyclic nucleosides, oligomeric compounds comprising at least one of the tricyclic nucleosides and methods of using the oligomeric compounds. The methods provided herein include contacting a cell or administering to an animal at least one of the oligomeric compounds. In certain embodiments, the oligomeric compounds hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
