摘要:
The invention features an improved lipid formulation comprising a cationic lipid of formula (A), a neutral lipid, a sterol and a PEG or PEG-modified lipid, where R1 and R2 are independently alkyl, alkenyl or alkynyl, each can be optionally substituted, and R3 and R4 are independently lower alkyl or R3 and R4 can be taken together to form an optionally substituted heterocyclic ring. In one embodiment, R1 and R2 are independently selected from oleoyl, pamitoyl, steroyl, linoleyl and R3 and R4 are methyl. Also disclosed are targeting lipids, and specific lipid formulations comprising such targeting lipids.

The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the ALAS1 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of ALAS1.
摘要:
The invention provides methods for delivering a double-stranded nbonucleic acid (dsRNA) to the central nervous system of a subject, and particularly, to oligodendrocytes of a subject by localized delivery to the brain, e.g., to the corpus caïlosum. For example, the dsRNA molecules can include a first sequence that is selected from the Sroup consisting of the sense sequences of Tables 8, 10, 13-16, and a second sequence selected from the group consisting of the antisense sequences of Tables 8, 10, and 13-16. The dsRNA molecules can include naturally occurring nucleotides or can include at least one modified nucleotide, such as a 2′-O-methyl modified nucleotide, a nucleotide comprising a 5′-phosphorothioate group, or a terminal nucleotide linked to a conjugate group, such as to a cholesteryl derivative or a vitamin E group. Alternatively, the modified nucleotide may be chosen from the group consisting of a 2f-deoxy-2′-fliιioro modified nucleotide, a 2′-de-oxy-modified nucleotide, a locked nucleotide, an abasic nucleotide, 2′-amino-modified nucleotide, 2′-alkyl-modified nucleotide, morpholino nucleotide, a phosphoramidate, and a non-natural bas comprising nucleotide. Generally, such modified sequences will be based on a first sequence of a dsRNA selected from the group consisting of the sense sequences of Tables 8, 10, and 13-16, and a second sequence selected from the group consisting of the antisense sequences of Tables 8 10, and 13-16.
