Disclosed herein are glutathione-sensitive oligonucleotides and methods of using the same. Any oligonucleotide of interest may be modified with a glutathione-sensitive moiety, including oligonucleotides used for in vivo delivery, such as nucleic acid inhibitor molecules. Typically, the glutathione-sensitive moiety is used to reversibly modify the 2'-carbon of a sugar moiety in one or more nucleotides in the oligonucleotide, although other carbon positions may also be modified with the glutathione-sensitive moiety. Also disclosed are glutathione- sensitive nucleotide and nucleoside monomers, including glutathione-sensitive nucleoside phosphoramidites that can be used, for example, in standard oligonucleotide synthesis methods. In addition, glutathione-sensitive nucleotide and nucleoside monomers without a phosphoramidite can be used therapeutically, for example, as anti-viral agents.
