Provided herein are peptides and variant peptides that exhibit enhanced activity at the GLP-1 receptor, as compared to native glucagon.

Glucagon/GLP-1 receptor co-agonists

Disclosed herein are insulin agonist peptides conjugated to incretins wherein the incretin-insulin conjugate has agonist activity at the insulin receptor and the corresponding incretin receptor, and stimulates weight loss in an individual administered the compound.

Incretin-insulin conjugates

Provided herein are glucagon analogs which exhibit potent activity at the GIP receptor, and, as such are contemplated for use in treating diabetes and obesity. In exemplary embodiments, the glucagon analog of the present disclosures exhibit an EC50 at the GIP receptor which is within the nanomolar or picomolar range.

Analogs of glucagon exhibiting GIP receptor activity

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 (KRNRNNIA) and SEQ ID NO: 28 (KRNR).

Modified glucagon peptides are disclosed having improved solubility and stability, wherein the native glucagon peptide has been modified by pegylation, or the addition of a carboxy terminal peptide selected from the group consisting of SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, or both.

Glucagon analogs exhibiting physiological solubility and stability

Modified glucagon peptides are disclosed having enhanced potency at the glucagon receptor relative to native glucagon. Further modification of the glucagon peptides by forming intramolecular 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, acylation, alkylation, substitution of carboxy terminal amino acids, C-terminal truncation, or the addition of a carboxy terminal peptide selected from the group consisting of SEQ ID NO: 26 (GPSSGAPPPS), SEQ ID NO: 27 (KRNRNNIA) and SEQ ID NO: 28 (KRNR).

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).

Modified glucagon peptides are disclosed having improved solubility and/or half-life while retaining glucagon agonist activity. The glycogen peptides have been modified by substitution of native amino acids with, and/or addition of, charged amino acids to the carboxy terminus of the peptide. The modified glucagon agonists can be further modified by pegylation, or the addition of a carboxy terminal peptide selected from the group consisting of SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 23, or both to further enhance the solubility of the glucagon agonist analogs.
