SYNTHESIS AND USE OF ISOTOPICALLY-LABELLED GLYCANS

Isotopically-labelled glycans and their synthesis and use as internal standards in the analysis by mass spectrometry of glycan mixtures is described. The methods of synthesis described herein may be used conveniently to prepare libraries of heavy glycans for use in the qualitative and quantitative identification of glycans in natural samples.

Efficient synthesis of meningococcal X polysaccharide repeating unit (n-acetylglucosamine-4-phosphate) as analytical standard for polysaccharide determination

Serogroup X Neisseria meningitidis (MenX) is emerging in many African countries as a major cause of meningococcal meningitis, but no preventative therapy against this serogroup is yet available. N-Acetylglucosamine-4-phosphate (4P-GlcNAc), the monomeric repeating unit of MenX polysaccharide, is an important requirement for the development of an analytical method specific for MenX polysaccharide quantification. At the moment, this compound is not commercially available. Herein an efficient preparation of this monosaccharide is reported.

MENINGOCOCCUS SEROGROUP X CONJUGATE

The invention provides a conjugate of a Neisseria meningitidis serogroup X capsular polysaccharide and a carrier molecule. The conjugate is typically made by (a) oxidising a primary hydroxyl group in the capsular polysaccharide, to give an oxidised polysaccharide with an aldehyde group; and (b) coupling the oxidised polysaccharide to a carrier molecule via the aldehyde group, thereby giving the conjugate. The conjugate may be part of an immunogenic composition. This composition may comprise one or more further antigens, particularly capsular polysaccharides from serogroups A, W135, C and Y and conjugated forms thereof. The composition may be in an aqueous formulation. The composition is useful as a vaccine, e.g. for raising an immune response in a mammal. The invention also provides processes for making the conjugate.

A preparative synthesis of human chitinase fluorogenic substrate (4' -deoxychitobiosyl)-4-methylumbelliferone

To meet the increasing clinical demand for the diagnostic agent (4′-deoxychitobiosyl)-4-methylumbelliferone, a flexible and scalable route of synthesis is needed. In this paper such a route is presented. The key to the route is the use of a partially protected thiophenyl glucosamine as starting material for the preparation of both the reducing and nonreducing end building blocks of the 4′-deoxychitobiose disaccharide.

Six D-glucosamine derivatives, diversely substituted at the nitrogen atom, were tested as acceptors in glycosylation reactions with 1,3,4,6-tetra-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranose (1) as the donor and trimethylsilyl trifluoromethanesulfonate as the promoter.The observed yields were high with 2-phthalimido- and 2-azido-D-glucosamine acceptors and more generally good with acceptors of the 1,6-anhydro-D-glucosamine series.The disaccharides benzyl 4-O-(3,4,6-tri-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranosyl)-3,6-di-O-benzyl-2-deoxy-2-phthalimido-β-D-glucopyranoside (20), benzyl 4-O-(3,4,6-tri-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranosyl)-2-allyloxycarbonylamino-3,6-di-O-benzyl-2-deoxy-β-D-glucopyranoside (21), 4-O-(3,4,6-tri-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranosyl)-1,6-anhydro-2-azido-3-O-benzyl-2-deoxy-β-D-glucopyranose (22), 4-O-(3,4,6-tri-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranosyl)-2-allyloxycarbonylamino-1,6-anhydro-3-O-benzyl-2-deoxy-β-D-glucopyranose (23), 2-acetamido-4-O-(3,4,6-tri-O-acetyl-2-allyloxycarbonylamino-2-deoxy-β-D-glucopyranosyl)-1,6-anhydro-3-O-benzyl-2-deoxy-β-D-glucopyranose (24) and 2-acetamido-4-O-(2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-β-D-glucopyranosyl)-1,6-anhydro-3-O-benzyl-2-deoxy-β-D-glucopyranose (25) have thus been synthesized.
