The present invention relates to the field of biopharmaceuticals, and in particular to a protein, a protein conjugate, a pharmaceutical composition and its use for treating diabetes. The fusion protein of the present invention is obtained by linking two polypeptides, wherein one polypeptide is an interleukin-1 receptor antagonistic protein or an analogue thereof, and another polypeptide is GLP-1 receptor binding polypeptide or an analogue thereof, or an insulin receptor binding polypeptide or an analogue thereof, or a GIP receptor binding polypeptide or an analogue thereof. The fusion proteins of the present invention and conjugates thereof have a significant efficacy in treating diabetes, and can be used in a lower dose, resulting in marked reduction in side effects.
本发明涉及生物制药领域,尤其涉及一种蛋白质、一种蛋白质共轭物、一种药物组合物及其治疗糖尿病的用途。本发明的融合蛋白是通过连接两种多肽获得的,其中一种多肽是白介素-1 受体拮抗蛋白或其类似物,另一种多肽是 GLP-1 受体结合多肽或其类似物,或胰岛素受体结合多肽或其类似物,或 GIP 受体结合多肽或其类似物。本发明的融合蛋白及其共轭物对治疗糖尿病有显著疗效,而且使用剂量较低,副作用明显减少。
