  • Publication number: 20160175430
    Abstract: The present invention relates to methods of manufacture of immunogenic glycoconjugates, in particular for use in pharmaceutical compositions for inducing a therapeutic immune response in a subject. The immunogenic glycoconjugates of the invention comprise one or more oligosaccharides or polysaccharides that are conjugated to one or more carrier proteins via an active aldehyde group. Accordingly, the invention provides methods of making (i) unsaturated microbial N-acyl derivative oligosaccharides or polysaccharides; (ii) novel conjugates of unsaturated N-acyl derivatives; and (iii) glycoconjugate compositions comprising conjugate molecules of fragments of microbial unsaturated N-acyl derivatives that serve as a covalent linker to one or more proteins. The invention further encompasses the use of the immunogenic glycoconjugates pharmaceutical compositions for the prevention or treatment of an infectious disease.

  • Publication number: 20150093411
    Abstract: The present invention provides multivalent chimeric conjugate vaccine molecule and methods of using the conjugate to immunize subjects against bacterial infections. A conjugate molecule of the invention comprises multiple bacterial capsular polysaccharides linked to a carrier protein. Accordingly, the conjugate molecule provides immune protection against multiple types of bacteria in a single vaccines. In particular, conjugate molecules of the invention are used to prevent or attenuate Group B Streptococcus and meningococcal infections.

  • Publication number: 20070054870
    Abstract: Compounds and methods are provided for modulating in vitro and in vivo processes mediated by selectin binding. More specifically, selectin modulators and their use are described, wherein the selectin modulators that modulate (e.g., inhibit or enhance) a selectin-mediated function comprise particular glycomimetics alone or linked to a member of a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids) or a member of a class of compounds termed BACAs (Benzyl Amino Carboxylic Acids).

  • Publication number: 20070037775
    Abstract: Compositions and methods are provided related to Pseudomonas bacteria. The compositions and methods may be used for diagnosis and therapy of medical conditions involving infection with Pseudomonas bacteria. Such infections include Pseudomonas aeruginosa in the lungs of patients with cystic fibrosis. A compound useful in the present methods may be used in combination with a therapeutic agent or may be linked to a therapeutic agent. Pseudomonas bacteria may be inhibited by blocking colonization, inhibiting virulence factors, arresting growth or killing the bacteria.
