Methods for synthesizing proinsulin polypeptides are described that include contacting a proinsulin polypeptide including an insulin polypeptide coupled to one or more peptides by peptide bond(s) capable of being cleaved to yield the insulin polypeptide with an oligomer under conditions sufficient to couple the oligomer to the insulin polypeptide portion of the proinsulin polypeptide and provide a proinsulin polypeptide-oligomer conjugate, and cleaving the one or more peptides from the proinsulin polypeptide-oligomer conjugate to provide the insulin polypeptide-oligomer conjugate. Methods of synthesizing proinsulin polypeptide-oligomer conjugates are also provided as are proinsulin polypeptide-oligomer conjugates. Methods of synthesizing C-peptide polypeptide-oligomer conjugates and other pro-polypeptide-oligomer conjugates are also provided.
描述了合成前胰岛素多肽的方法,包括将包括胰岛素多肽和一个或多个肽段的前胰岛素多肽与一个寡聚体接触,这些肽段通过肽键结合,可以被切割以产生胰岛素多肽,条件足以将寡聚体与前胰岛素多肽的胰岛素多肽部分结合并提供前胰岛素多肽-寡聚体共轭物,并从前胰岛素多肽-寡聚体共轭物中切割一个或多个肽段,以提供胰岛素多肽-寡聚体共轭物。还提供了合成前胰岛素多肽-寡聚体共轭物的方法,以及前胰岛素多肽-寡聚体共轭物。还提供了合成C肽多肽-寡聚体共轭物和其他前多肽-寡聚体共轭物的方法。
