    摘要: Glucagon antagonists are provided which comprise amino acid substitutions and/or chemical modifications to glucagon sequence. In one embodiment, the glucagon antagonists comprise a native glucagon peptide that has been modified by the deletion of the first two to five amino acid residues from the N-terminus and (i) an amino acid substitution at position 9 (according to the numbering of native glucagon) or (ii) substitution of the Phe at position 6 (according to the numbering of native glucagon) with phenyl lactic acid (PLA). In another embodiment, the glucagon antagonists comprise the structure A-B-C as described herein, wherein A is PLA, an oxy derivative thereof, or a peptide of 2-6 amino acids in which two consecutive amino acids of the peptide are linked via an ester or ether bond.

    摘要: Prodrug formulations of bioactive polypeptides are provided wherein the bioactive polypeptide has been modified by the linkage of a dipeptide to the bioactive polypeptide through an ester linkage. The prodrugs disclosed herein in some embodiments have extended half lives of at least 1.5 hours (e.g., at least 10 hours), and more typically greater than 20 hours and less than 70 hours, and are converted to the active form at physiological conditions through a non-enzymatic reaction driven by chemical instability.

    摘要: Modified glucagon peptides are disclosed having enhanced potency at the glucagon receptor relative to native glucagon. Further modification of the glucagon peptides by forming lactam bridges or the substitution of the terminal carboxylic acid with an amide group produces peptides exhibiting glucagon/GLP-1 receptor co-agonist activity. The solubility and stability of these high potency glucagon analogs can be further improved by modification of the polypeptides by pegylation, substitution of carboxy terminal amino acids, or the addition of a carboxy terminal peptide selected from the group consisting of SEQ ID NO: 26 (GPSSGAPPPS), SEQ ID NO: 27 (K-RNRNNIA) and SEQ ID NO: 28 (KRNR).
