摘要:
Methods for diagnosing pathology of the liver in a subject suspected of having such pathology are disclosed. The methods comprise quantifiably detecting glycosylation, and more specifically fucosylation, on proteins in biological fluids, and comparing the detected glycosylation with reference values for the glycosylation of such proteins in healthy or disease states.
摘要:
The present invention provides methods, compositions, apparatus, and kits for assessing glycoforms of proteins as a biomarker for disease. A purified recombinant form of lectin is used as a detector molecule to specifically label target sugars expressed in disease states. The high affinity of recombinant lectin allows for automation of assays that would be used in the diagnosis of diseases such as, but not limited to, cancer or liver disease.

Provided are methods and compositions for treating hepatitis virus infections in mammals, especially humans. The methods comprise (1) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or immunomodulating/immunostimulating agents, or (2) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, or mixtures thereof, and immunomodulating/immunostimulating agents.
摘要:
A method is disclosed for the treatment of hepatitis B virus (HBV) infections which comprises administering to the infected host an N-alkyl derivative of 1,5-dideoxy-1,5-imino-D-glucitol in which the alkyl group contains from 3 to 6 carbon atoms.
摘要:
Long chain N-alkyl amino and imino compounds, oxa-substituted derivatives thereof, and pharmaceutical compositions including such compounds are described. The long chain N-alkyl group is a C8-C16 alkyl group. The long chain N-alkyl compounds and oxa-substituted derivatives thereof can be used in the treatment of viral infections, in particular hepatitis B virus or hepatitis C virus, in a cell or an individual. For example, the long chain N-alkyl compounds or oxa-substituted derivatives thereof can be derived from piperidines, pyrrolidines, phenylamines, pyridines, pyrroles, or amino acids.

摘要:
Imino sugars, such as deoxynojirimycin (DNJ), are glucose analogues that selectively inhibit cellular α-glucosidase I and II (enzymes that process N-linked glycans in glycoprotein) and exhibit broad spectrum antiviral activities against many enveloped viruses. Previously we have reported a novel DNJ derivative, OSL-95II, with antiviral activity and reduced cytotoxicity. In order to develop imino sugars with more potent antiviral activity as well as improved toxicity profile, OSL-95II was modified by diversifying the nitrogen linked alkylated side chain. The antiviral activities were initially tested in bovine viral diarrhea virus (BVDV) infected MDBK cells, yielding several imino sugar derivatives with novel structure and superior antiviral activity and toxicity profile. Furthermore, these new compounds were shown to be active against Dengue virus (DV) and West Nile virus (WNV) infection in BHK cells where potent anti-DV activity having submicromolar EC50 values and SI of greater than 900. These compounds represent a new generation of iminio sugars and their analogues, having application in the clinical treatment of infection of DV and other members of flaviviridae.
摘要:
This invention describes a relevant etiology of cancer and a novel anti-cancer therapeutic strategy, based on the discovery that a protein named serine protease inhibitor (SPIK/SPINK/PSTI) was up-regulated by hepatitis B and C virus infections consequently suppressing the cell apoptosis. Accordingly, this invention provides an inhibitor of SPIK and/or a technology of suppression of over-expression of SPIK in cells. The inhibitors include: 1) chemical compounds, which can inhibit SPIK transcripts, protein activity, and gene expression, 2) SPIK siRNA (RNAi gene silence or dsRNA of SPIK, 3) DNA anti-sense and anti-SPIK antibody. Further, this invention provides a method of using the inhibitor as an anti-cancer agent to re-instate cancer cell apoptosis (e.g., serine protease dependent cell apoptosis). Also provided is an anti-SPIK antibody specific for an epitope comprising the first nine amino acids of intact SPIK. Further, a diagnostic kit is provided comprising at least one antibody specific for an epitope comprising the first nine amino acids of intact SPIK to diagnose patients exhibiting disease symptoms or at risk for developing a disease, wherein the disease is HBV infection, HCV infection, hepatitis, cancer or hepatic cancer.
