    • The present disclosure provides recombinantly expressed insulin polypeptides that comprise an N-linked glycan motif. The N-linked glycan motif is not present in wild-type insulins and enables the recombinant expression of glycosylated insulin polypeptides (e.g., in yeast cells). Based on results obtained with synthetic glycosylated insulin conjugates we predict that when these recombinant glycosylated insulin polypeptides are administered to a mammal, at least one pharmacokinetic or pharmacodynamic property of the glycosylated insulin polypeptide will be sensitive to serum concentrations of glucose (or an exogenous saccharide such as alpha-methyl mannose). Exemplary insulin polypeptides, polynucleotides encoding these insulin polypeptides, glycosylated insulin polypeptides, pharmaceutical formulations and sustained release formulations are provided in addition to methods of use and preparation.
    • 本公开提供了包含N-连接的聚糖基序的重组表达的胰岛素多肽。 N-连接的聚糖基序不存在于野生型胰岛素中并且能够重组表达糖基化胰岛素多肽(例如在酵母细胞中)。 基于用合成糖基化胰岛素缀合物获得的结果,我们预测当将这些重组糖基化胰岛素多肽施用于哺乳动物时,糖基化胰岛素多肽的至少一种药代动力学或药效学性质将对血清葡萄糖浓度(或外源糖类 作为α-甲基甘露糖)。 除了使用和制备方法外,还提供了示例性的胰岛素多肽,编码这些胰岛素多肽的多核苷酸,糖基化的胰岛素多肽,药物制剂和缓释制剂。
