Patent ID: 11390642

Abstract:
Disclosed herein are glutathione-sensitive oligonucleotides and methods of using the same. The glutathione-sensitive oligonucleotides may comprise at least one nucleotide represented by Formula I: wherein A, B, I, J, L, R1, R2, R3, R4, U1, U2, W, and X are as defined in the specification. An illustrative glutathione-sensitive oligonucleotide of the disclosure may have the following chemical structure:  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. 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.
