摘要:
The invention features a oligonucleotide of formula I, or pharmaceutically acceptable salts, or prodrugs thereof: which are capable of inducing an anti-viral or an antibacterial response, in particular, the induction of type I IFN, IL-18 and/or IL-1β by binding to RIG-I. The invention relates to methods of making and using modified oligonucleotide comprising at least one triphosphate or analogs thereof. The invention further relates to methods for treating various disorders and diseases such as viral infections, bacterial infections, parasitic infections, tumors, allergies, autoimmune diseases, immunodeficiencies and immunosuppression.
摘要:
The present invention provides compounds of formula (1). 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:
The present invention provides nucleosides and oligonucleotides comprising a 5′ phosphate mimics of formula (IVc) or (Vc). One aspect of the present invention relates to modified nucleosides and oligonucleotides comprising such dinucleotide of formula (Ia). 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:
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.
