  The invention features a hybridized polynucleotide construct including a passenger strand, a guide strand loadable into a RISC complex, and one or more auxiliary moieties. At least one of the auxiliary moieties is non-bioreversibly linked to an internucleoside phosphate or phosphorothioate in the passenger strand. The invention further features methods of delivery a polynucleotide construct to a cell and methods of reducing the expression of a protein in a cell. The methods typically involve contacting the cell with the hybridized polynucleotide construct.

  The disclosure provides methods and compositions for delivering polynucleotides into cells. The disclosure provides transiently protected polynucleotides comprising an anionic charge-neutralizing moiety/group, which may also confer additional functionality. These compounds can enter the cytosol of cells by endocytic or macropinocytic mechanisms. The transient protecting group is bioreversible, i.e., once inside a cell, it is designed to be removed by enzymatic activity or by passive intracellular methods (e.g., changes in pH or reductive environment).

  该披露提供了将多核苷酸传递到细胞中的方法和组合物。该披露提供了暂时保护的多核苷酸，其中包含一个阴离子电荷中和的基团，这可能还赋予了额外的功能。这些化合物可以通过内吞或巨胞吞噬机制进入细胞的细胞质。暂时的保护基团是可生物逆转的，即一旦进入细胞内，它被设计为能够通过酶活性或被动的细胞内方法（例如，pH值的变化或还原环境）来去除。

  Disclosed is a method for indirectly coupling a small molecule ligand to a molecule to be labelled with the ligand, the method comprising the step of: contacting a scaffold molecule, to which is attached at least one small molecule ligand, with the molecule to be labelled, the scaffold molecule having at least one group which is reactive towards a receiver moiety present or formed in situ on the molecule to be labelled, so as to forma bond between the scaffold molecule and the molecule to be labelled, thereby indirectly coupling the small molecule ligand to the molecule to be labelled.
