Iminosugar glycoconjugates

The iminosugar conjugates according to the invention are N-alkylated 1,5-dideoxy-1,5-iminohexitol or 1,5-dideoxy-1,5-iminopentitol derivatives. The iminosugar component can be, for example, D-gluco-, L-ido-, D-galacto-, D-manno-, 2-acetamido-2-deoxy-D-gluco- or xylo-configuration. The N-substituent is a protected L-alpha-aminoacid derivative, showing L-lysine-like structural features. The linkage between the carbohydrate and the peptide component is not via the usual glycosidic position, but shows structural features of a very stable tertiary amine. Thus the linkage is very stable. These new compounds are synthesised by using catalytic intramolecular reductive amination of dicarbonyl sugars with partially protected amino acids. The process of intramolecular reductive amination itself is carried out using Pearlman’s catalyst (Pd(OH)2/C) and H2 at ambient pressure and room temperature. The resulting accessible class of iminosugar conjugate compounds is represented by the general structure shown in Figure 4(c). The alkyl chain length parameter n can be freely chosen from n=0 upwards. Preferably n is between 0 and 10, and more preferably n is 2, 3, or 4. Residue R1 can be chosen from H, OH, or NHAc, with Ac being Acetyl. R2 can be H, OH, or NHAc. R3, R4, R5, R6 can be H or OH. R7 and R8 can be H, CH2OH CH3, COQH, or COOR with R being Alkyl or Aryl. R9 and R10 can be chosen from H, NH2, NHR, with R being a protective group, an amino acid, a peptide, or a protein. R11 can be OH, O-Alkyl, O-Aryl, NH2, N-Alkyl, N-Aryl, amino acid or peptide, connected via an amide bond.

A new approach to the neoglycopeptides: Synthesis of urea- and carbamate-tethered N-acetyl-D-glucosamine amino acid conjugates

(Chemical Equation Presented) A novel approach to the synthesis of Fmoc-protected neoglycopeptide building blocks is described. Oxidation of N-acetyl-D-glucosamine isonitrile afforded the corresponding highly reactive glycopyranosyl isocyanate, which reacted with amino acid derivatives to furnish the corresponding urea- and carbamate-tethered Fmoc-protected N-acetyl-D-glucosamine amino acid conjugates in good yields.

Probing multivalent carbohydrate-lectin interactions by an enzyme-linked lectin assay employing covalently immobilized carbohydrates

We report here the synthesis of a series of mono- to trivalent N-acetylglucosamine (GlcNAc) derivatives as ligands for the plant lectin wheat germ agglutinin (WGA). Their WGA binding potencies were determined by an established enzyme-linked lectin assay (ELLA) employing microtiter plates with non-covalently immobilized porcine stomach mucin (PSM) as reference ligand and an ELLA with a new GlcNAc derivative covalently immobilized via a thiourea linkage. Comparison of both assays revealed that the type of presentation of GlcNAc residues on the microtiter plates either as part of a glycoprotein or as a covalently immobilized monosaccharide derivative strongly influences the outcome of the assay. Although the apparent dissociation constants KDELLA for the interaction of peroxidase-labeled WGA with the microtiter plates are comparable for both surfaces, IC50 values obtained with the PSM-free ELLA were substantially lower. Even more strikingly, this ELLA displayed a better differentiation between ligands of different valency leading to significantly higher relative inhibitory potencies of multivalent ligands compared to monovalent. Additionally, problems associated with the use of PSM, such as maximum inhibition at considerably less than 100% and poor reproducibility of IC50 values could be overcome with this type of ELLA.

Synthesis of beta-D-fructofuranosyl-(2?1)-2-acetamido-2-deoxy- alpha-D-glucopyranoside (N-acetylsucrosamine) using beta-fructofuranosidase- containing Aspergillus oryzae mycelia as a whole-cell catalyst

Using soft granules consisting of Celite 535 and dried Aspergillus oryzae NBRC100959 mycelia containing beta-fructofuranosidase as a whole-cell catalyst, N-acetylsucrosamine [beta-d-fructofuranosyl-(2?1)-2-acetamido- 2-deoxy-alpha-d-glucopyranoside] was produced from sucrose and 2-acetamido-2-deoxy-d-glucose by enzymatic transfructosylation. The isolated yield of N-acetylsucrosamine from the reaction mixture was 22.1% (from sucrose). The result of N-terminal amino acid sequence analysis indicated that the enzyme involved in the synthesis of N-acetylsucrosamine is a product from gene (NCBI accession number; NW-001884675, locus tag; AOR-1-1114084) encoding putative beta-fructofuranosidase on chromosome 6 of strain NBRC100959. The N-acetylsucrosamine we produced is highly soluble in water and is more stable in acidic solution than sucrose. The disaccharide was also produced using dried mycelia prepared from another A. oryzae strains.

Thiyl glycosylate of olefinic proteins: S-linked glycoconjugate synthesis

Tagged for thiolation: A novel glycoconjugation strategy utilizes a non-natural olefin-containing amino acid (homoallylglycine, Hag) as a “tag” for modification and a photoinitiated hydroglycothiolation reaction that is selective only for the Hag olefinic “tag”. Application of this method to a number of model proteins allowed complete and precise site-selective glycosylate generating glycoconjugates that include, for example, virus-like particles displaying up to 180 glycans at preselected positions (see scheme).

Stereoisomer Differentiation of 2-Acetamido-2-deoxyhexose by Mass Spectrometric Measurement of Relative Gas-Phase Alkali Ion Affinities

Cationized dimers + of 2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-D-mannose, and 2-acetamido-2-deoxy-D-galactose were generated by fast atom bombardment (FAB) using different alkali cations and glycerol, S-valerolactame, and diethanolamine matrices.From their unimolecular decomposition (metastable ions) mainly two kinds of ions are observed resulting from the retention of the cation either by the amino sugar (ion a) or/and by the matrix (ion b).For a given hexosamine their relative abundance depends on the alkali cation and the matrixused.When the matrix is diethanolamine and the alkali cation is lithium or sodium, the N-acetylglucosamine stereoisomers can be differentiated by the relative abundances of ions a and b of the cationized dimer.
