摘要:
Provided herein are modified 5′ diphosphate nucleosides and oligomeric compounds prepared therefrom. More particularly, modified 5′ diphosphate nucleosides are provided that can be further modified at the 2′ and 5′ positions. In some embodiments, the oligomeric compounds provided herein are expected to hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA. The oligomeric compounds are also expected to be useful as primers and probes in diagnostic applications.
摘要:
The present invention provides nucleosides of formula (1) and oligonucleotides comprising at least on nucleoside of formula (2):Formula (1) and Formula (2). Another aspect of the invention relates to a method of inhibiting the expression of a gene in call, the method comprising (a) contacting an oligonucleotide of the invention with the cell; and (b) maintaining the cell from step (a) for a time sufficient to obtain degradation of the mRNA of the target gene.

摘要:
Compositions comprising first and second oligomers are provided wherein at least a portion of the first oligomer is capable of hybridizing with at least a portion of the second oligomer, at least a portion of the first oligomer is complementary to and capable of hybridizing to a selected target nucleic acid, and at least one of the first or second oligomers includes a modified sugar and/or backbone modification. In some embodiments the modification is a 2′ substituent group on a sugar moiety that is not H or OH. Oligomer/protein compositions are also provided comprising an oligomer complementary to and capable of hybridizing to a selected target nucleic acid and at least one protein comprising at least a portion of an RNA-induced silencing complex (RISC), wherein at least one nucleotide of the oligomer has a modified sugar and/or backbone modification.
