The present disclosure provides conjugates that comprise an insulin molecule conjugated via a conjugate framework to two or more separate ligands that each include a saccharide, wherein the framework, ligand, saccharide and insulin molecule optionally comprise a fatty chain (e.g., a C8-30 fatty chain), wherein when said insulin molecule is conjugated both to a C8-30 fatty chain and one or more separate ligands that each include a saccharide, said C8-30 fatty chain is linked to insulin molecule only, and wherein when the framework or ligand comprises a fatty chain the insulin molecule is conjugated to two or more separate ligands. In certain embodiments, a conjugate is characterized in that, when the conjugate is administered to a mammal, at least one pharmacokinetic (PK) and/or pharmacodynamic (PD) property of the conjugate is sensitive to serum concentration of a second saccharide. In certain embodiments, a conjugate is also characterized by having a protracted PK profile. Exemplary conjugates and sustained release formulations are provided in addition to methods of use and preparation.
本公开提供了包含胰岛素分子通过一个共轭框架与两个或更多个单独的配体结合的共轭物,每个配体都包括一个糖苷的共轭物,其中该框架、配体、糖苷和胰岛素分子可选择包括一个脂肪链(例如,一个C8-30脂肪链),当所述胰岛素分子既与一个C8-30脂肪链结合又与一个或多个包括糖苷的单独的配体结合时,所述C8-30脂肪链仅与胰岛素分子连接,当该框架或配体包括一个脂肪链时,胰岛素分子与两个或更多个单独的配体结合。在某些实施例中,一个共轭物的特征在于,当将该共轭物注射给哺乳动物时,该共轭物的至少一个药代动力学(PK)和/或药效动力学(PD)特性对第二糖苷的血清浓度敏感。在某些实施例中,一个共轭物还具有持续的PK特性。除了使用和制备方法外,还提供了示例共轭物和缓释制剂。
