摘要:
The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to cell in vivo. The pharmacokinetic modulator improve in vivo targeting compared to the targeting ligand alone. Targeting ligand-pharmacokinetic modulator targeting moiety targeted RNAi polynucleotides can be administered in vivo alone or together with co-targeted delivery polymers.
摘要:
The present invention is directed compositions for delivery of RNA interference (RNAi) polynucleotides to cells in vivo. The compositions comprise amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or DPC) are further covalently linked to an RNAi polynucleotide or co-administered with a targeted RNAi polynucleotide-targeting molecule conjugate.

The present invention provides novel amino-lipids, compositions comprising such amino-lipids and methods of producing them. In addition, lipid nanoparticles comprising the novel amino-lipids and a biologically active compound are provided, as well as methods of production and their use for intracellular drug delivery.
摘要:
The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to hepatocytes in vivo. Targeted RNAi polynucleotides are administered together with co-targeted melittin delivery peptides. Delivery peptides provide membrane penetration function for movement of the RNAi polynucleotides from outside the cell to inside the cell. Reversible modification provides physiological responsiveness to the delivery peptides.
摘要:
This invention relates to modified double-stranded oligoribonucleic acid (dsRNA) having improved stability in cells and biological fluids, and methods of making and identifying dsRNA having improved stability, and of using the dsRNA to inhibit the expression or function of a target gene.
摘要:
The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of the Nav1.8 gene (Nav1.8 gene), comprising an antisense strand having a nucleotide sequence which is less that 25 nucleotides in length and which is substantially complementary to at least a part of the Nav1.8 gene. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier; methods for treating diseases caused by the expression of the Nav1.8 gene using the pharmaceutical composition; and methods for inhibiting the expression of the Nav1.8 gene gene in a cell.
摘要:
The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of the Huntingtin gene (HD gene), comprising an antisense strand having a nucleotide sequence which is less than 25 nucleotides in length and which is substantially complementary to at least a part of the HD gene. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier; methods for treating diseases caused by the expression of the HD gene, or a mutant form thereof, using the pharmaceutical composition; and methods for inhibiting the expression of the huntingtin gene in a cell.
