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.
本文披露了谷胱甘肽敏感的寡核苷酸以及使用这些寡核苷酸的方法。感兴趣的任何寡核苷酸都可以通过谷胱甘肽敏感的基团进行修饰,包括用于体内传递的寡核苷酸,比如核酸抑制分子。通常,谷胱甘肽敏感的基团用于可逆地修饰寡核苷酸中一个或多个核苷酸的糖基的2'-碳,尽管其他碳位置也可以用谷胱甘肽敏感的基团进行修饰。此外,本文还披露了谷胱甘肽敏感的核苷酸和核苷单体,包括谷胱甘肽敏感的核苷酸磷酰胺二酰胺,例如,可以在标准寡核苷酸合成方法中使用。此外,没有磷酰胺二酰胺的谷胱甘肽敏感的核苷酸和核苷单体可以在治疗中使用,例如作为抗病毒剂。
