  • Patent number: 8957106
    Abstract: A proliferation of cells can be reduced by contacting the cells with a compound having formula (I) where R and R? are each alkyl groups, R? is hydrogen or an alkyl group and X3, X4 and X5 are each independently selected from the group consisting of hydrogen, benzyl, t-butyldimethylsiloxy radical and triphenylmethyl. Accordingly, compounds of formula (I) can be used for treatment of tumors including melanoma. Also a secretion of a matrix metalloproteinase (MMP) enzyme by cells can be reduced by contacting the cells with the compound having formula (I). Accordingly, compounds of formula (I) can be used for treatment physiological conditions associated with an elevated MMP level, such as tumors.

  • 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.

  • 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.

  • Publication number: 20080085526
    Abstract: The inventors have proposed a novel panel of human serum 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. Serum from patients with varying degrees of hepatic scarring induced by infection with the hepatitis C virus (HCV) was analysed. Several proteins associated with liver scarring and/or viral infection were identified. These proteins include the inter-?-trypsin inhibitor heavy chain H4 fragments, complement factor H-related protein 1, CD5L, Apo L1, and ?2GPI. Increased and decreased thiolester cleavage of a2M and Complement C3, respectively, was also detected. The concentrations of these novel biomarkers can be determined using an immunoassay where the concentrations would reflect the extent of fibrosis. A fibrosis scoring scale for each of the novel biomarkers is proposed.

  • Publication number: 20060269974
    Abstract: One can identify and quantify one or more glycosylation markers of cancer 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. One can utilize the identified glycosylation marker, for example, for diagnosing and/or monitoring cancer in a subject. One can also use the glycosylation marker to identify glycoprotein biomarkers that carry the glycosylation marker. Such biomarkers can also be used for monitoring and/or diagnosing cancer. The biomarker may also be a subset of glycoforms of a glycoprotein that are separated in trains of spots on 2D gel.

  • Publication number: 20060269979
    Abstract: One can identify and quantify one or more glycosylation markers of an autoimmune disease such as rheumatoid arthritis 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 utilized for monitoring and/or diagnosing the autoimmune disease.

  • Publication number: 20060270048
    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: 20060134099
    Abstract: Human rabies monoclonal antibodies (rabies MAbP) comprising rabies human MAb S057 heavy chain and light chain subunits are expressed and assembled in plants under the control of two strong constitutive promoters. Additionally, regulatory control elements such as alfalfa mosaic virus untranslated leader sequence and Lys-Asp-Glu-Leu (KDEL) endoplasmic reticulum retention signal were linked at the N- and C-terminus of the heavy chain of human rabies MAbP, respectively to regulate expression of the rabies MAbP. Rabies MAbP was as effective at neutralizing the activity of the rabies virus as the mammalian-derived antibody (MAbM) or human rabies immunoglobulin (HRIG).
