The invention features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains one or more bulky groups proximal to the disulfide group. The invention also features polynucleotide constructs containing one or more components (i) containing a disulfide linkage, where each of the one or more components (i) is attached to an internudeotide bridging group or a terminal group of the polynucleotide construct, and each of the one or more components (i) contains at least 4 atoms in a chain between the disulfide linkage and the phosphorus atom of the internudeotide bridging group or the terminal group; and where the chain does not contain a phosphate, an amide, an ester, or an alkenylene. The invention also features methods of delivering a polynucleotide to a cell using the polynucleotide constructs of the invention.
该发明涉及包含一个或多个组分(i)的聚核苷酸构造,其中每个一个或多个组分连接到聚核苷酸构造的一个核苷酸桥连基团或末端基团上,每个一个或多个组分(i)包含靠近二硫键的一个或多个臃肿基团。该发明还涉及包含一个或多个组分(i)的聚核苷酸构造,其中每个一个或多个组分(i)连接到聚核苷酸构造的一个核苷酸桥连基团或末端基团上,每个一个或多个组分(i)在二硫键和核苷酸桥连基团或末端基团的磷原子之间的链中至少包含4个原子;并且该链不包含磷酸酯、酰胺、酯或烯基烃。该发明还涉及使用该发明的聚核苷酸构造将聚核苷酸传递到细胞的方法。
