  • Patent number: 8921568
    Abstract: Iminosugar compounds are described that have inbuilt delivery features by virtue of covalent incorporation of a tocopherol moiety, or alternative moieties that are analogs of tocopherol or select analogs of cholesterol, or its antagonist “Ezitimibe”; and are likely to have broad spectrum antiviral activity. The compounds differ from previous iminosugar compounds, even lipophillic ones, being more hydrophobic and resembling fats and oils in their partition behavior in vivo into lipid phases of lipoproteins, cellular lipid droplet organelles and biological membranes. These features confer a number of unique delivery attributes in vivo, favorable to the therapy of virus infections involving cells of the lymphoid system and the liver, in particular, but these features are also favorable in general for the treatment of virus infections of man and animals.

  • Patent number: 8889364
    Abstract: The inventors have proposed a novel panel of human plasma protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Plasma from patients with hepatic cirrhosis induced by infection with the hepatitis C virus (HCV) were analyzed. Several proteins associated with liver scarring and potentially also related to viral infection were identified. These proteins include 14-3-3 protein zeta/delta, adiponectin, afamin, alpha-1-antitrypsin, alpha-2-HS-glycoprotein, apolipoprotein C-III, apolipoprotein E, C4b-binding protein beta chain, intact/cleaved complement C3dg, corticosteroid-binding globulin, fibrinogen gamma chain, beta haptoglobin at pH 5.46-5.

  • Patent number: 8039208
    Abstract: One can identify and quantify one or more glycosylation markers of a physiological condition such as a disease or a stage of disease by utilizing quantitative HPLC analysis of glycans which have been released from unpurified glycoproteins. The unpurified glycoproteins can be total glycoproteins or a selection of the total glycoproteins. The identified glycosylation marker can be a native glycan or a digestion product which has been segregated and amplified by exoglycosidase digestions. This strategy is compatible with a high throughput format and glycan data base searching. One can utilize the identified glycosylation marker, for example, for monitoring the physiological condition in a subject. One can also use the glycosylation marker to identify glycoproteins that carry the glycosylation marker which can also be used to monitor the physiological condition. The biomarker may also be a subset of glycoforms of a glycoprotein that are separated in trains of spots on 2D gel.

  • Publication number: 20110184019
    Abstract: 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.

  • Publication number: 20110182982
    Abstract: One can treat a viral infection such as hepatitis B (HBV), hepatitis C(HCV), and bovine viral diarrhea virus (BVDV) infections via the delivery of pH sensitive liposomes directly into the endoplasmic reticulum (ER) membrane. Two exemplary liposome formulations are DOPE/CHEMS (DC liposomes) and DOPE/CHEMS/PEG-PE (DCPP liposomes). DC and DCPP liposomes can optimize the intracellular delivery of N-butyl deoxynojirimycin (NB-DNJ), and consequently increase the in vivo activity of this iminosugar several orders of magnitude, and could be used in combination with other therapeutic agents such as interferon and/or ribavirin. The optimized release of NB-DNJ directly into the ER can be also applied for the treatment of other viruses, for which NB-DNJ is known to be an effective antiviral, such as human immunodeficiency virus (HIV).

  • Publication number: 20110143351
    Abstract: The present invention provides novel biomarkers for use in the diagnosis and prognosis of cancerous and malignant conditions and further of diseases which are mediated by a proinflammatory immune response. The biomarkers are glycoproteins, the levels of expression of which have been correlated by the inventors to correspond to particular disease conditions. The invention further extends to methods for use in monitoring the response to therapy of a treatment for use in the treatment of a cancerous condition or proinflammatory disease.
