摘要:
The present invention relates to proteins which specifically bind to IgA1 and which have been modified to comprise either O- or N-linked glycans. The invention encompasses methods for decreasing IgA1, preferably abnormally glycosylated IgA1, in an individual by administering to the individual a glycan-modified IgA1 binding protein of the invention. The invention also encompasses a method for the treatment of a disease characterized by IgA1 deposition wherein a glycan-modified IgA1 binding protein is administered to an individual in need thereof.
摘要:
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.
摘要:
A method of inhibiting the growth of Helicobacter pylori is described. The method involves administering to a mammal a composition containing a surfactant/emulsifying agent and which is substantially free of calcium, magnesium, aluminum and silicon ions.
摘要:
A compound having the structure ##STR1## where T is of the fomrula ##STR2## where each D.sup.1 and D.sup.2, independently, is a hydroxyl group of a group which is capable of being hydrolysed to a hydroxyl group in aqueous solution at physiological pH; a group of the formula ##STR3## where G is either H,F or an alkyl group containing 1 to about 20 carbon atoms and optional heteroatoms which can be N, S, or O; or a phosphonate group of the formula ##STR4## where J is O-alkyl, N-alkyl, or alkyl, each comprising about 1-20 carbon atoms and, optionally, heteroatoms which can be N, S, or O; T being able to form a complex with the catalytic site of an enzyme, X is a group having at least one amino acid, ##STR5## and each R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, and R.sup.8 is separately a group which does not interfere significantly (i.e., does not lower than Ki of the compound to less than 10.sup.-7 M) with site-specific recognition of the compound by the enzyme, and allows a complex to be formed with the enzyme.

摘要:
The present invention features noninvasive methods for diagnosing IgA or IgM kidney disorders, such as IgA nephropathy, Henoch-Schönlein purpura, and IgM nephropathy, in a mammal. The invention also features compositions and kits useful in diagnosing these disorders.
摘要:
The present invention provides methods for modification and regulation of glucagon-like peptide 1 (GLP-1) metabolism by administering therapeutically effective amounts of an inhibitor of dipeptidylpeptidase IV (DPIV) or a pharmaceutically acceptable salt thereof, where the inhibitor has a Ki for inhibition of DPIV of 10 nM or less; and the inhibitor is administered in an amount sufficient to inhibit DPIV proteolysis of GLP-1 but not sufficient to suppress the immune system of the animal.
摘要:
The present invention discloses the use of bacterial IgA1 proteases to treat IgA1 deposition in tissue and organs. Bacterial IgA1 proteases specifically cleave IgA1 molecules and thus provide a means to specifically cleave and remove IgA1 depositions. Accordingly, therapeutic agents for the treatment of diseases characterized by IgA deposition are provided. In particular, therapeutic agents to treat IgA nephropathy, Dermatitis herpetiformis (DH), and Henoch-Schoenlein purpura (HS) are disclosed.

摘要:
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.
