Abstract

See full text

The present disclosure relates to novel nucleotide precursors and nucleotide analogs that can be incorporated into oligonucleotides, including double-stranded oligonucleotides such as siRNAs. Oligonucleotides containing these analogs have superior biological activity, for example, increased in vitro stability and improved in vivo potency especially duration of action. The improved oligonucleotides are useful for silencing (e.g., reducing or eradicating) the expression of a target gene. In particular embodiments, this invention encompasses specific nucleotide analogs to be included in double-stranded RNAs (dsRNAs), and especially in siRNAs, that can hybridize to messenger RNAs (mRNAs) of interest, so as to reduce or block the expression of target genes of interest. The present compounds have general formula (I), wherein each of Ra, Rb, Rc and Rd is independently, H or a (C1-C6) alkyl group and B is a heterocyclic nucleobase.
