摘要:
A process for the recombinant preparation of a calcitonin fragment and the use of the fragment in the preparation of calcitonin and related analogs is provided. The process includes recombinantly forming a fusion protein which includes the calcitonin fragment linked to a carbonic anhydrase. The recombinantly formed fusion protein is subsequently cleaved to produce a polypeptide which includes the calcitonin fragment. A method for producing a calcitonin carba analog which includes condensing a desaminononapeptide with the recombinantly formed calcitonin fragment is also provided.

摘要:
A method for the isolation and/or purification of a recombinant peptide by employing a fusion protein construct which includes a carbonic anhydrase and a variable fused polypeptide is provided. The method includes precipitating either the fusion protein construct or a fragment of the fusion protein construct including the carbonic anhydrase. Inclusion bodies which includes the fusion protein construct and a method of producing a peptide which includes expressing the fusion protein construct as a part of an inclusion body are also provided. Fusion protein constructs which include a carbonic anhydrase and certain target peptides are also provided.

The invention relates to methods for treating a patient suffering from acute coronary syndrome, but who is not suffering from a Q-wave myocardial infarction, comprising administration of a therapeutically effective amount of a GLP-1 molecule. The GLP-1 can be self-administered, and can be administered in one or more doses, as needed, on an intermittent or continuous basis, to optimize metabolism in cardiac tissue and to prevent cardiac damage associated with ischemia.

A composition and method for improved administration of nutrients is described. The method includes co- or separate administration of a source of nutrients, especially carbohydrates, and insulintropic peptides and derivatives, analogs, fragments and the like. The method and composition provide high carbohydrate nutrition while avoiding hyper- and hypoglycemia and their attendant deleterious effects.
摘要:
It has now been discovered that GLP-1 treatment after acute stroke or hemorrhage, preferably intravenous administration, can be an ideal treatment because it provides a means for optimizing insulin secretion, increasing brain anabolism, enhancing insulin effectiveness by suppressing glucagon, and maintaining euglycemia or mild hypoglycemia with no risk of severe hypoglycemia.
摘要:
The invention provides a method of producing a polypeptide having a C-terminal α-carboxamide group. It particularly concerns an enzymatic modification of selected substrate polypeptides which result in cleavage of the substrate polypeptide to form a product peptide with a C-terminal arginine residue having an α-carboxamide group (C-terminal 'Arg-NH2'). The method includes contacting an aqueous-based solution including (i) ammonia reagent and (ii) the substrate polypeptide with (iii) clostripain.
摘要:
The invention provides for a chemical method for preparing a recombinant single copy polypeptide or a portion thereof with a modified terminal amino acid α-carbon reactive group selected from the group consisting of N-terminal α-amine, C-terminal α-carboxyl, and a combination thereof. The steps of the method involve forming the recombinant single copy polypeptide or a portion thereof so that the single copy polypeptide is protected with one or more biologically added protecting groups at the N-terminal α-amine, C-terminal α-carboxyl. The recombinant single copy polypeptide can then be reacted with up to three chemical protecting agents to selectively protect reactive side chain groups and thereby prevent side chain groups from being modified. The recombinant single copy polypeptide can be cleaved with at least one cleavage reagent specific for the biological protecting group to form an unprotected terminal amino acid α-carbon reactive group. The unprotected terminal amino acid α-carbon reactive group is modified with at least one chemical modifying agent. The side chain protected terminally modified single copy polypeptide is then deprotected at the side chain groups to form a terminally modified recombinant single copy polypeptide. The number and sequence of steps in the method can be varied to achieve selective modification at the N- and/or C-terminal amino acid of a recombinantly produced polypeptide.
摘要:
Individuals in need of treatment of ischemia-related reperfusion are treated, preferably intravenously, with a composition which includes a compound which binds to a receptor for the glucagon-like peptide-1. The invention relates to both the method and compositions for such treatment.
