The invention is directed to oligonucleotides and oligonucleosides functionalized to include lipophilic moieties and having improved biostability and altered biodistribution in mammals. In one embodiment, such lipophilic oligonucleotide conjugates are used in a method of targeting antisense oligonucleotides to hepatic tissues and thereby preferentially modulating gene expression in the liver and associated tissues of a mammal.
本发明涉及功能化含有亲脂性基团的寡核苷酸和寡核苷酸的寡聚体,其在哺乳动物中具有改善的生物稳定性和改变的生物分布。在一种实施方式中,这种亲脂性寡核苷酸共轭物被用于一种将反义寡核苷酸定向至肝组织并因此优先调节哺乳动物肝脏及相关组织基因表达的方法中。
