    • Provided herein are glucagon analogs comprising a modified amino acid sequence of native human glucagon (SEQ ID NO: 2) that exhibit activity at the glucagon receptor, activity at the GLP-1 receptor, or activity at each of the glucagon receptor and the GLP-1 receptor. In some embodiments, the glucagon analog exhibits at least 100% or more of the activity of native glucagon at the glucagon receptor and/or at least 100% or more of the activity of native GLP-1 at the GLP-1 receptor. In some embodiments, the glucagon analog has an EC50 at the GLP-1 receptor which is within 50-fold or less than the EC50 at the glucagon receptor. In some embodiments, the glucagon analog has an EC50 at the GLP-1 receptor which is two- to ten-fold greater than the EC50 at the glucagon receptor. Related conjugates, dimers and multimers, and pharmaceutical compositions, and uses thereof, are further provided.
    • 本文提供的是包含显示胰高血糖素受体活性,GLP-1受体活性或每种胰高血糖素受体和GLP-1受体活性的天然人胰高血糖素(SEQ ID NO:2)的修饰氨基酸序列的胰高血糖素类似物, 1受体。 在一些实施方案中,胰高血糖素类似物在胰高血糖素受体上表现出至少100%或更多的天然胰高血糖素的活性和/或天然GLP-1在GLP-1受体的至少100%或更多的活性。 在一些实施方案中,胰高血糖素类似物在GLP-1受体处具有在胰高血糖素受体的50倍或更小的EC 50内的EC 50。 在一些实施方案中,胰高血糖素类似物具有GLP-1受体的EC 50,其比胰高血糖素受体的EC50大2至10倍。 还提供了相关的缀合物,二聚体和多聚体,以及药物组合物及其用途。
