摘要:
Single chain insulin analogs are provided having high potency and specificity for the insulin receptor. As disclosed herein optimally sized linking moieties can be used to link human insulin A and B chains, or analogs or derivatives thereof, wherein the carboxy terminus of the B25 amino acid of the B chain is linked to the amino terminus of the A1 amino acid of the A chain via the intervening linking moiety. In on embodiment the linking moiety comprises a polyethylene glycol of 6-16 monomer units and in an alternative embodiment the linking moiety comprises a non-native amino acid sequence derived form the IGF-1 C-peptide and comprising at least 8 amino acids and no more than 12 amino acid in length. Also disclosed are prodrug and conjugate derivatives of the single chain insulin analogs.

Methods are provided for administering an extended half-life GLP-1/GIP coagonist peptide to a patient in need thereof for reducing weight gain, inducing weight loss, treating hyperglycemia, reducing blood glucose levels, or normalizing blood glucose levels in said patient.
摘要:
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.
摘要:
Insulin-like growth factor analogs are disclosed wherein substitution of the IGF native amino acids, at positions corresponding to positions B16 and B17 of native insulin, with tyrosine and leucine, respectively, increases potency of the resulting analog at the insulin receptor by tenfold. Also disclosed are prodrug and depot formulations of the IGF analogs, wherein the IGF analog has been modified by the linkage of a dipeptide to the analog through an amide bond linkage. The prodrug and depot formulations disclosed herein have extended half lives of at least 2 hours, 10 hours, and more typically greater than 2 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 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.
