Described are novel targeting ligands that may be linked to compounds, such therapeutic compounds that are useful in directing the compounds to the in vivo target. 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 a therapeutic 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.
本文介绍的新型靶向配体可与化合物(如治疗性化合物)连接,有助于将化合物导向体内靶点。本文公开的靶向配体可用于将表达抑制性寡聚化合物(如 RNAi 制剂)靶向肝细胞,以调节基因表达。本文公开的靶向配体与治疗化合物连接后可用于多种应用,包括治疗、诊断、靶点验证和基因组发现应用。包括本文公开的靶向配体的组合物与表达抑制性低聚化合物连接时,能够介导肝细胞(如肝细胞)中靶核酸序列的表达,这可能有助于治疗对细胞、组织或生物体中基因表达或活性的抑制有反应的疾病或病症。
