The present invention provides polypeptides that include an O-linked glycosylation site that is not present in the wild-type peptide. The polypeptides of the invention include glycoconjugates in which a species such as a water-soluble polymer, a therapeutic agent of a biomolecule is covalently linked through an intact O-linked glycosyl residue to the polypeptide. Also provided are methods of making a glycoconjugate, methods of isolating a glycoconjugate from a reaction mixture, pharmaceutical compositions containing a glycoconjugate, and methods of treating, ameliorating or preventing diseased in mammals by administering an amount of a glycoconjugate sufficient to achieve the desired response.
本发明提供了包括一个O-连接糖基化位点的多肽,该位点不存在于野生型多肽中。本发明的多肽包括糖基共轭物,其中一种物种,如水溶性聚合物、生物分子的治疗剂通过完整的O-连接糖基残基与多肽共价连接。还提供了制备糖基共轭物的方法、从反应混合物中分离糖基共轭物的方法、含有糖基共轭物的药物组合物以及通过给予足够量的糖基共轭物来治疗、改善或预防哺乳动物疾病的方法,以达到所需的反应。
