  • Publication number: 20160303243
    Abstract: The invention relates to anionic conjugates of glycosylated bacterial metabolites that may be used to mimic the structure and/or activity of the anionic bioactive molecules known as glycosaminoglycans (GAGs). The invention also relates to processes for the preparation of the conjugates. Such conjugates are useful in the prophylaxis and/or treatment of disease conditions and in particular chronic disease conditions such as inflammatory (including allergic) diseases, metastatic cancers and infection by pathogenic agents including bacteria, viruses or parasites.

  • Patent number: 8209131
    Abstract: The present invention relates generally to chemical agents useful in the prophylaxis and/or treatment of disease conditions and in particular chronic disease conditions such as inflammatory including allergic diseases, metastatic cancers and infection by pathogenic agents including bacteria, viruses or parasites. More particularly, the chemical agents contemplated by the present invention are selected from glycosaminoglycan (GAG) molecules derived from a larger GAG, GAG-like molecules which resemble GAGs in some of their characteristics but may be derived from a larger non-GAG polysaccharide and molecules having a GAG-like composite structure as well as agents which bind to the same sites as GAGs, GAG-like molecules or GAG-like composite molecules. The present invention also provides assays to identify GAG and GAG-like therapeutic agents including GAG-like composite structures as well as analogs, homologs and orthologs thereof.

  • Patent number: 6077951
    Abstract: The present invention consists in methods of preparing derivatives either isolation or from glycopeptides or glycoproteins. The methods comprise producing sugar hydrazones, sugar pyrazoles, glycosylpyrazones, azoglycan dyes and hydrazoglycan dyes. The present invention also relates to the removal of O-glycans from glycopeptides or glycoproteins, immobilising reducing sugars onto solid supports and methods to obtain sugars from glycopeptide or glycoprotein comprising subjecting the glycopeptide or glycoprotein to solid-phase Edman degradation followed by separating and characterizing the sugars.
