The present invention discloses fusion proteins comprising transferrin, lactoferrin or melanotransferrin fused to glucagon-like peptide 1 (GLP-1). In one embodiment of the invention, the fusion protein displays increased serum half-life as compared to a GLP-1 peptide in an unfused state. The invention includes a pharmaceutical composition comprising the GLP-1 fusion protein of the invention and a carrier. The fusion protein of the invention can be administered to a subject for treatment of diseases or conditions treatable by GLP-1, including, but not limited to, diabetes, obesity, congestive heart failure and inflammatory bowel syndrome.

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.

A method is provided for detecting a change in posture of a subject. An electrical impedance is measured between two or more sites on a stomach (20) of the subject, and an impedance signal is generated responsive thereto. The change in posture is detected by performing a posture analysis of the impedance signal. A method is also provided for treating a subject. The method includes applying an electrical signal to a site of the subject selected from the list consisting of: a colon (402) of the subject, and a distal small intestine (408) of the subject. The signal is configured to stimulate cells of the subject to increase secretion of glucagon-like-peptide-1 (GLP-1) or PYY, or to decrease secretion of ghrelin, in order to treat the subject.

The present invention relates to methods of treating polycystic ovary syndrome (PCOS) comprising administering glucagon-like peptide-1 (GLP-1) to subjects suffering therefrom.

In general this invention can be viewed as encompassing novel methods of treating diabetes and insulin resistance. The inventors have made the discovery that increasing secretion of endogenous glucagon-like peptide-1 (GLP-1) in combination with inhibiting the activity of dipeptidyl peptidase I (DPP-IV) can have a significant impact on hyperglycemia and insulin secretion in subjects suffering from diabetes and/or insulin resistance. Further the invention encompasses methods of identifying subjects having elevated secretion of GLP-1, methods of assessing sensitivity to a GLP-1 secretagogue, and methods of treating diabetes in these subjects by administering a GLP-1 secretagogue to alleviate at least one symptom of diabetes.

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 present invention relates to methods of treating intermittent claudication comprising administering glucagon-like peptide-1 (GLP-1) molecules to subjects suffering therefrom.

A composition for the treatment of impaired glucose tolerance (IGT) including a compound which binds to a receptor for glucagon-like peptide-1, and a pharmaceutical carrier. The amount of the compound present is an effective amount to improve pancreatic β-cell sensitivity to blood glucose levels in a human with IGT. Also, a method for improving the pattern of insulin secretory responses in a human with IGT by administering to the human a composition comprising a compound which binds to a receptor for glucagon-like peptide-1 and a pharmaceutical carrier.

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 present invention relates to methods of treating polycystic ovary syndrome (PCOS) comprising administering glucagon-like peptide-1 (GLP-1), exendin, and analogs and agonists thereof, to subjects suffering therefrom.

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.

The invention relates to a novel GLP-1 analog and the application thereof. The GLP-1 analog with higher stability and higher hypoglycemic activity is obtained by reconstructing 8, 22 amino acid residue sites of natural GLP-1. The chemical synthesis is achieved at high efficiency and high speed by using microwave to promote solid phase synthesis, and the crude product is purified by a preparative grade HPLC and lyophilized to obtain the GLP-1 analog.

Compounds that bind the glucagon-like peptide 1 (GLP-1) receptor, methods of their synthesis, methods of their therapeutic and/or prophylactic use, and methods of their use in stabilizing GLP-1 receptor in vitro for crystallization of the GLP-1 receptor are provided. Certain compounds may have activity as modulators or potentiators with respect to glucagon receptor, GIP receptor, GLP-1 and GLP-2 receptors, and PTH receptor on their own or in the presence of receptor ligands such as GIP (1-42), PTH (1-34), Glucagon (1-29), GLP-2 (1-33), GLP-1 (7-36), GLP-1 (9-36), oxyntomodulin and exendin variants.

The present invention relates to a novel peptide showing more excellent activities on a glucagon like peptide-1 receptor and a glucagon receptor than native oxyntomodulin, and a composition for the prevention or treatment of obesity comprising the peptide as an active ingredient. Unlike native oxyntomodulin, the novel peptide of the present invention reduces food intake, suppresses gastric emptying, and facilitates lipolysis with reduced side-effects, and also shows excellent receptor-activating effects. Thus, it can be widely used in the treatment of obesity with safety and efficacy.
