  • Publication number: 20250243485
    Abstract: Described are novel targeting ligands that may be linked to compounds, such therapeutic compounds, that are useful in directing the compounds to the target in vivo. The targeting ligands disclosed herein can serve to target expression-inhibiting oligomeric compounds, such as RNAi agents, to liver cells to modulate gene expression. The targeting ligands disclosed herein, when conjugated to an expression-inhibiting oligomeric compound, may be used in a variety of applications, including use in therapeutic, diagnostic, target validation, and genomic discovery applications. Compositions including the targeting ligands disclosed herein when linked to expression-inhibiting oligomeric compounds are capable of mediating expression of target nucleic acid sequences in liver cells, such as hepatocytes, which may be useful in the treatment of diseases or conditions that respond to inhibition of gene expression or activity in a cell, tissue, or organism.

  • Publication number: 20250113829
    Abstract: Post-transcriptionally chemically modified double strand RNAs (MdsRNAs) and post-transcriptionally chemically modified RNAs (MRNAs) having a high molecular weight polyalkyloxy modification at the 2?-OH position are described. This modification allows for greater bioavailability of the compound, better stability of the compound, and allows for greater stability against nucleases. The MdsRNAs and MRNAs can be economically produced in a readily scalable manner. Compositions of MdsRNAs and MRNAs having chemically modified nucleotides are described, such that the MdsRNAs and MRNAs are modified to contain high molecular weight polyalkyloxy polymers. Synthetic methods for efficiently making these MdsRNAs and MRNAs and methods of using MdsRNAs and MRNAs are described.
