Modified insulinotropic peptides are disclosed. The modified insulinotropic peptides are capable of forming a peptidase stabilized insulinotropic peptide. The modified insulinotropic peptides are capable of forming covalent bonds with one or more blood components to form a conjugate. The conjugates may be formed in vivo or ex vivo. The modified peptides are administered to treat humans with diabetes and other related diseases.

The present invention relates to a novel method for the production of short chain polypeptides, including polypeptides having up to 3 disulfide bonds and/or structures rich in basic amino acid residues, and open structured short chain polypeptides, e.g. glucagon, glucagon like peptides and their functional analogues, in genetically modified yeast cells, said genetically modified yeast cells, and a method for the preparation of said yeast cells.

The present invention provides pharmaceutical agents comprising a dipeptidyl peptidase IV (DPPIV) inhibitor and a biguanide agent in combination, which enhance the effects of active circulating glucagon-like peptide-1 (GLP-1) and/or active circulating glucagon-like peptide-2 (GLP-2).

Method for increasing the shelf-life of a pharmaceutical composition for parenteral administration comprising a glucagon-like peptide which is prepared from a peptide product that has been subjected to treatment at a pH above neutral pH.

The present invention relates to use of GLP-1 or a related molecule having GLP-effect for the manufacture of a medicament for preventing or treating diabetes in a mammal. The amount and timing of administration of said medicament are subsequently reduced to produce a “drug holiday”. Practice of the invention achieves effective therapy without continuous drug exposure and without continuous presence of therapeutic levels of the drug. The invention also discloses a method of treating diabetes and related disorders in a mammal by administering glucagons like peptide (GLP-1) or a related molecule having GLP-1 like effect and thereby providing a therapeutically effective amount of endogenous insulin.

What is described is a pharmaceutical formulation for intranasal delivery of glucagon-like protein-1 (GLP-1), comprising an aqueous mixture of GLP-1, a solubilizing agent, a chelator, and a surface active agent.

The present invention provides polypeptides that include an O-linked glycoconjugate in which a species such as a water-soluble polymer, a therapeutic agent of a biomolecule is covalently linked through an intact O-linked glycosyl residue to the polypeptide. The polypeptides of the invention include wild-type peptides and mutant peptides that include an O-linked glycosylation site that is not present in the wild-type peptide. Also provided are methods of making the peptides of the invention and methods, pharmaceutical compositions containing the peptides and methods of treating, ameliorating or preventing diseased in mammals by administering an amount of a peptide of the invention sufficient to achieve the desired response.

Method for increasing the shelf-life of a pharmaceutical formulation comprising a glucagon-like peptide.

The invention provides the use of a whey protein and/or whey protein hydrolysate which stimulate the cellular release of the satiety peptides choleocystokinin and glucagon-like-peptide in the preparation of edible compositions. The edible compositions can be used to control body weight and have beneficial effects on satiety. Edible compositions are also provided.

The present invention is directed to peptide analogues of glucagon-like peptide-1, the pharmaceutically-acceptable salts thereof, to methods of using such analogues to treat mammals and to pharmaceutical compositions useful therefor comprising said analogues.

The invention relates to a method for biosynthesis preparation of human glucagon-like peptide-1 (GLP-1) and an analogue thereof. With adopting of a gene engineering technology, a recombinant escherichia coli expressed GLP-1 fusion protein is constructed, and a protein enzyme digestion site is designed in the fusion protein; a fusion gene has a gene sequence with a form of A-B-C structure, wherein A is a chaperonin gene, B is a nucleotide sequence encoding a connection peptide containing the enzyme digestion site, and C is a gene encoding the GLP-1 or the analogue thereof. After recombinant engineering bacteria is subjected to induced expression, the fusion protein is purified and subjected to enzyme digestion, and then the GLP-1 and the analogue thereof are obtained and are detected to have biological activity. The preparation method of the GLP-1 and the analogue thereof provided by the invention is simple and quick, the production conditions are mild, the product is convenient to separate and extract, the process is simple, and the industrialization prospect is good.

Pharmaceutical composition for parenteral administration comprising a glucagon-like peptide and human serum albumin or a variant thereof.

The invention discloses a glucagon like peptide(GLP)-1 mutant polypeptide and a preparation method, a medicinal composition and use thereof. The mutant polypeptide is formed by bonding a Cys-containing elongation peptide to the N terminal of the glucagon like peptide-1 mutant, the mutant polypeptide itself folds to form a disulfide bond. The glucagon like peptide-1 mutant polypeptide is used for preparing a medicinal composition for treating diabetes and treating and preventing obesity. For overcoming the drawbacks of short retention time in body and need of daily injection administration of clinic GLP-1 analogue, the invention provides the GLP-1 analogue which has a longer half-life period. With the longer half-life period, the GLP-1 mutant polypeptide is not required to be injected into a patient every day, and can increase the obedience of the patient effectively.

The present invention is directed to peptide analogues of glucagon-like peptide-1, the pharmaceutically-acceptable salts thereof, to methods of using such analogues to treat mammals and to pharmaceutical compositions useful therefore comprising said analogues.

The present invention relates to dual incretin peptide mimetic compounds that agonize receptors for both human glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), and may be useful for treating type 2 diabetes mellitus (T2D).

The invention relates to a cell strain for measuring the bioactivity of GLP-1 and functional analogue thereof and an application of the cell strain and belongs to the technical field of measurement of drug bioactivity. The GLP-1R/HEK293 cell strain is preserved in the common microorganism center of China microorganism culture preservation management committee and the preservation number is CGMCCNo.5909. The invention relates to a measuring method for establishing express glucagon peptide-1 receptor (GLP-1R) genetic engineering cell strain GLP-1R/HEK293 and measuring the bioactivity of GLP-1 and analogue thereof in external stimulation on the basis of the change in the cAMP level in the cell after the GLP-1R/HEK293 cell strain is stimulated by the glucagon peptide-1 receptor (GLP-1R) and the functional analogue thereof. The measuring method is easily standardized, is excellent in repeatability and has the characteristics of low cost, convenience and accuracy, thereby being excellent in application prospect.
