摘要:
The present invention relates to RNA agents for inhibiting the expression of a target human gene in a cell, comprising a sense sequence and an antisense sequence, wherein the sense sequence has one or more asymmetrical 2'-O alkyl modifications and the antisense sequence has 4-20 phosphorothioate modifications, wherein the RNA agent comprises a multivalent galactose or a multivalent N-acetylgalactosamine, and wherein the antisense sequence targets the human gene sequence.
摘要:
The present invention relates to a cationic lipid having one or more biodegradable groups located in the mid- or distal section of a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.
摘要:
The present invention relates to an iRNA agent comprising different modifications as well as to a method of increasing the nuclease resistance of a duplex.
摘要:
The features of the present invention relate to compounds, compositions and methods useful for modulating the expression of vascular endothelial growth factor (VEGF), such as by the mechanism of RNA interference (RNAi). The compounds and compositions include iRNA agents that can be unmodified or chemically-modified.
