摘要:
Compositions and formulations comprising insulin or insulin analogs comprising a carboxy terminal portion (CTP) peptide comprising amino acids 112-118 to 145 of the beta subunit of human chorionic gonadotropin (hCGβ) or a partial variant thereof that includes at least one O-glycosylation site of the CTP peptide, wherein the CTP peptide of the CTP peptide-based insulin or insulin analog is O-glycosylated are described. In particular embodiments, the O-glycosylated insulin analogs are produced in vivo and in further embodiments, the O-glycosylated CTP-based insulin analogs comprise predominantly mannotriose and mannotetrose O-glycans or predominantly mannose O-glycans.
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.
摘要:
Provided herein are glucagon superfamily peptides conjugated with GR ligands that are capable of acting at a glucocorticoid receptor. Also provided herein are pharmaceutical compositions and kits of the conjugates of the invention. Further provided herein are methods of treating a disease, e.g., a metabolic disorder, such as diabetes and obesity, comprising administering the conjugates of the invention.
摘要:
Provided herein are peptide combinations comprising a GIP agonist peptide and a glucagon antagonist peptide. In some embodiments, the peptide combination is provided as a composition, e.g., a pharmaceutical composition, while in other embodiments, the peptide combination is provided as a kit. In yet other embodiments, the peptide combination is provided as a conjugate, e.g., a fusion peptide, a heterodimer. In specific aspects, the GIP agonist peptide is an analog of native human glucagon. In specific aspects, the glucagon antagonist peptide is an analog of native human glucagon. In some embodiments, the GIP agonist peptide is covalently attached to the glucagon antagonist peptide via a linker. Method of treating a disease, e.g., a metabolic disorder, such as diabetes and obesity, comprising administering the peptide compositions described herein are further provided.
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 (KRNRNNIA) and SEQ ID NO: 28 (KRNR).
