  • Publication number: 20190211333
    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: 20190078088
    Abstract: The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents, capable of inhibiting Apolipoprotein C-III (also called APOC3, apoC-III, APOC-III, and APO C-III) gene expression, and compositions that include APOC3 RNAi agents. The APOC3 RNAi agents disclosed herein may be conjugated to targeting ligands, including ligands that include N-acetyl-galactosamine, to facilitate the delivery to cells, including to hepatocytes. Pharmaceutical compositions that include one or more APOC3 RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the APOC3 RNAi agents in vivo provides for inhibition of APOC3 gene expression, and can result in lower triglycerides and/or cholesterol levels in the subject. The APOC3 RNAi agents can be used in methods of treatment of APOC3-related diseases and disorders, including hypertriglyceridemia, cardiovascular disease, and other metabolic-related disorders and diseases.

  • Publication number: 20190010494
    Abstract: Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of an alpha-ENaC (SCNN1A) gene. The alpha-ENaC RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of an alpha-ENaC gene. Pharmaceutical compositions that include one or more alpha-ENaC RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described alpha-ENaC RNAi agents to epithelial cells, such as pulmonary epithelial cells, in vivo, provides for inhibition of alpha-ENaC gene expression and a reduction in ENaC activity, which can provide a therapeutic benefit to subjects, including human subjects.

  • Publication number: 20180312537
    Abstract: Described herein are methods of modifying a peptide with a chemical agent. The peptide may be an amphipathic peptide, such as a melittin-like peptide. The reactants are dissolved in an organic solvent and the reaction is allowed to proceed during sequential additions of a first base and a second base. Reaction in organic solvent with sequential base additions yields greater than 90% modification of both N-terminal and internal primary amine modification.
