摘要:
The present invention provides novel peptides that can modulate the ghrelin receptor (growth hormone secretagogue receptor, GHS-R1a and sub-types, isoforms and variants thereof). These peptides are useful as antagonists of the ghrelin receptor as well as inverse agonist, partial agonist or a combination of these activities as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, gastrointestinal disorders, cardiovascular disorders, obesity and obesity-associated disorders, diabetes, central nervous system disorders, genetic disorders, and hyperpro-liferative disorders.

摘要:
This invention relates to methods and compositions for the treatment, management, reduction, or prevention of injuries to one or more major organs of the body, e.g., the brain, heart, lung, kidneys, liver, and gastrointestinal tract, of a mammal (e.g., a human) caused by one or more calcineurin or mammalian target of rapamycin (mTOR) complex inhibitors. The methods include administering an effective amount of one or more pituitary adenylate cyclase-activating polypeptide (PACAP)-like compounds to the mammal. Combination therapy with one or more PACAP-like compounds, either alone or in combination with one or more other prophylactic/therapeutic agents, plus one or more inhibitors of either calcineurin or the mTOR complexes can be used to treat organ transplantation, autoimmune diseases, graft-versus-host disease, Behçet's disease, hematological cancers, noninfectious uveitis, sarcoidosis, tuberous sclerosis complex, acute neurological diseases, age-related neurodegenerative diseases, Huntington's disease and other CAG codon repeat expansion diseases, keratoconjunctivitis sicca, and restenosis.
摘要:
The present invention relates to peptides and methods of inhibiting fusion between the virion envelope of Flaviviruses and membranes of the target cell, the process that delivers the viral genome into the cell cytoplasm. The invention provides for methods which employ peptides or peptide derivatives to inhibit Flavivirus:cell fusion. The present invention is based in part on the discovery that E1 envelope glycoprotein of hepaciviruses and E2 envelope glycoprotein of pestivirus have previously undescribed structures, truncated class II fusion proteins. The present invention provides peptides and methods of treatment and prophylaxis of diseases induced by Flaviviruses.
摘要:
The present invention is directed to a method for synthesizing a peptide using solid-state chemistry in which at least one amide bond is N-methylated, wherein said method of synthesis utilizes N-Boc protected amino acids. For example, the a peptide is first synthesized using N-BOC protected amino acids and 4-methylbenzylhydrylamine functionalized 1% cross linked polystyrene resin until reaching the amide bond to be N-methylated. Then, the amino group at the desired methylation site is methylated. If desired, the synthesis of additional peptide using N-BOC protected amino acids may continued until the desired peptide is complete.
摘要:
