Abstract: Peptide inhibitors of dipeptidyl-aminopeptidase type IV (DP-IV) are provided. The peptide inhibitors have an isomeric purity of about 96–99 percent. The peptide inhibitors include one or more amino acids covalently coupled to boroproline moiety. The compounds are useful as DP-IV inhibitors, in vivo and in vitro.

Abstract: The present invention provides methods and compositions for modification and regulation of glucose and lipid metabolism, generally to reduce insulin resistance, hyperglycemia, hyperinsulinemia, obesity, hyperlipidemia, hyperlipoproteinemia (such as chylomicrons, VLDL and LDL), and to regulate body fat and more generally lipid stores, and, more generally, for the improvement of metabolism disorders, especially those associated with diabetes, obesity and/or atherosclerosis. The compositions of the present invention include dipeptidylpeptidase inhibitors, which are able to inhibit the proteolysis of GLP-1 and accordingly increase the plasma half-life of that hormone. The subject inhibitors may be peptidyl, peptidomimetic (e.g. boronyl peptidomimetics), or non-peptidyl nitrogen containing heterocycles.

Abstract: The present invention provides methods and compositions for modifying glucose metabolism and treating Type II diabetes in an animal, along with modifying metabolism of a peptide hormone in an animal. Compositions disclosed herein comprise one or more peptides and/or peptide analogs which include a functional group that reacts with an active site residue of a protease.

Abstract: An inhibitory compound having the structure: Group I-Group II. Group I has the structure: where H represents a hydrogen; C represents a carbon; O represents an oxygen; N represents a nitrogen; each R, independently, is chosen from the group consisting of the R groups of an amino acid, including proline; each broken line, independently, represents a bond to an H or a bond to one R group, and each H′ represents that bond or a hydrogen; and p is an integer between 0 and 4 inclusive. Alternatively Group I has the structure: where n is between 0 and 3 inclusive, each G2 and G3 independently is H or C1-3 (one to three carbon atoms) alkyl, G1 is NH3 (H3 represents three hydrogens), (H2 represents two hydrogens), or where G5 and G6 can be NH, H, or C1-3 alkyl or alkenyl with one or more carbons substituted with a nitrogen. G1 bears a charge, and G1 and Group II do not form a covalently bonded ring structure at pH 7.0.

Abstract: The present invention provides methods and compositions for modification and regulation of GLP 1 metabolism, glucose and lipid metabolism, generally to reduce insulin resistance, hyperglycemia, hyperinsulinemia, obesity, hyperlipidemia, hyperlipoproteinemia (such as chylomicrons, VLDL and LDL), and to regulate body fat and more generally lipid stores, and, more generally, for the improvement of metabolism disorders, especially those associated with diabetes, obesity and/or atherosclerosis. The compositions described herein are high-affinity boronyl and non-boronyl peptidomimetic inhibitors of DPIV.

Abstract: A method for substantially reducing the pathogenicity of an infectious agent, without killing the infectious agent, by removing or degrading a surface protein of the infectious agent, by contacting the infectious agent with substantially pure, non-pasteurized, naturally occurring lactoferrin under conditions sufficient to remove or degrade the protein, is disclosed.

Abstract: The invention relates to an isolated nucleic acid encoding Streptococcus pneumoniae IgA protease and an isolated polypeptide comprising Streptococcus pneumoniae IgA protease and methods of use thereof.

Abstract: The application discloses a nickel binding protein and its encoding DNA isolated from Helicobacter pylori. This organism is the primary cause of chronic gastritis and ensuing peptic ulcers, and has been implicated in stomach cancer. The nickel binding protein is useful to inhibit assembly of active ureases, the enzymes responsible for the pathogenic features of the bacterium. Potential uses include as a vaccine, a diagnostic, a drug target, and a therapy in itself.
