A polymerizable alcohol having 9 PEG repeats was prepared in order to mimic an oligosaccharide moiety. Sialyl α(2→3) lactose, which is known as a sugar moiety of GM3 ganglioside, was also prepared, and the polymerizable alcohol was condensed with the sialyl α(2→3) lactose derivative to afford the desired glycomonomer, which was further polymerized with or without acrylamide to give water-soluble glycopolymers. The glycopolymers had higher affinities than those of glycopolymers having sialyl lactose moieties with shorter aglycon moieties.

A water-soluble glycomonomer having a sialyl α2 → 3 lactose (SLac) moiety was prepared from a known imidate derivative of the SLac and an acrylamide alcohol by means of Schmidt's protocol followed by transesterification. Polymerization of the monomer proceeded in water as the solvent in the presence of ammonium persulfate (APS)-tetramethylethylenediamine (TEMED). Since acryl amide (AAm) was used as a regulator for the arrangement of sugar density, three kinds of glycopolymers having different sugar densities were obtained. Infection inhibition assays of mumps virus (MuV) for Vero cells using the glycopolymers were performed, and the results showed that a glycopolymer having a low sugar density has the highest inhibitory potency. In comparison to sialyl Lewis X (SLeX) as the strongest inhibitor in a previous study, SLac polymer with the low sugar density showed ten-times stronger inhibitory potency than that of SLex. This finding suggested that multivalent conversion of the monomeric SLac with appropriate spatial arrangement are able to effectively inhibit the interaction between the attachment glycoprotein of MuV and glycan receptors on Vero cells.

Autoantibody signatures of circulating mucin fragments stem from cancer tissues, and microenvironments are promising biomarkers for cancer diagnosis and therapy. This study highlights dynamic epitopes generated by aberrantly truncated immature O-glycosylation at consecutive threonine motifs (TTX) found in mucins and intrinsically disordered proteins (IDPs). NMR analysis of synthetic mucin models having glycosylated TTX motifs and colonic MUC2 tandem repeats (TRs) containing TTP and TTL moieties unveils a general principle that O-glycosylation at TTX motifs generates a highly extended and rigid conformation in IDPs. We demonstrate that the specific conformation of glycosylated TTX motifs in MUC2 TRs is rationally rearranged by concerted motions of multiple dihedral angles and noncovalent interactions between the carbohydrate and peptide region. Importantly, this canonical conformation of glycosylated TTX motifs minimizes steric crowding of glycans attached to threonine residues, in which O-glycans possess restricted orientations permitting further sugar extension. An antiadhesive microarray displaying synthetic MUC2 derivatives elicited the presence of natural autoantibodies to MUC2 with impaired O-glycosylation at TTX motifs in sera of healthy volunteers and patients diagnosed with early stage colorectal cancer (CRC). Interestingly, autoantibody levels in sera of the late stage CRC patients were distinctly lower than those of early stage CRC and normal individuals, indicating that the anti-MUC2 humoral response to MUC2 neoepitopes correlates inversely with the CRC stage of patients. Our results uncovered the structural basis of the creation of dynamic epitopes by immature O-glycosylation at TTX motifs in mucins that facilitates the identification of high-potential targets for cancer diagnosis and therapy.

CM-Str (4-(Chloromethyl)styrene) was used as a useful starting material for the construction of a series of functional monomers. Substitution of the chlorine to the corresponding azide was performed, and the reduction of the azide proceeded smoothly to afford an aminostyrene, which was used as a common precursor for the preparation of functional monomers. Condensation of the amine with a fluorophore, biotin and carbohydrate was accomplished. Among the monomers, a carbohydrate monomer was polymerized with or without acrylamide as a model polymerization to yield the corresponding water-soluble glycopolymers, and biological evaluations of the glycopolymers for a lectin, and wheat germ agglutinin (WGA), were carried out on the basis of the fluorescence change of tryptophan in the WGA.

Bivalent glycoconjugates have a minimal valence with avidity potential on protein-carbohydrate interactions as well as simplicity of chemical structures enabling simple synthesis with low cost. Understanding the way to maximize the affinities of bivalent glycoconjugates is important for the development of cost-effective tools for therapeutic and diagnostic research. However, there has been little discussion about the effects of constraints imposed from ligand scaffolds on the binding abilities. We synthesized three kinds of biantennary N-acetylglucosamine glycosides with different scaffolds using isobutenyl bis(propargyl)ether as a common scaffold precursor. Decoration of the scaffold branches with GlcNAc moieties through copper-catalyzed azide-alkyne cycloaddition and grafting of the alkenyl focal point to another bivalent biotin dendron through thiol-ene and nucleophilic substitution reactions were successfully carried out in an orthogonal manner. The association constants of the ligands against wheat germ agglutinin were determined by a fluorometric titration assay. A bivalent biotin counterpart provided higher affinity than an isobutyl scaffold, whereas an isobutenyl scaffold yielded more enhancement than a bivalent biotin counterpart. The present work suggested that the constraint and steric bulk of ligand scaffolds are possible factors for improving binding properties of glycoconjugates against lectins or proteins.

Survivin, an inhibitor of the apoptosis protein family, is a potent tumor marker for diagnosis and prognosis. The enzyme-linked immunosorbent assay (ELISA) is one of the methods that has been used for detection of survivin. However, ELISA has several disadvantages caused by the use of conventional antibodies, and we have therefore been trying to develop a novel ELISA system using camelid single-domain antibodies (VHHs) as advantageous replacements. Here we report a supplemental approach to improve the VHH-polyclonal antibody sandwich ELISA for survivin detection. Iodoacetyl-functionalized pullulan was synthesized, and its thiol reactivity was characterized by a model reaction with L-cysteine. The thiophilic pullulan was applied to an immunoassay as an additive upon coating of standard assay plates with an anti-survivin VHH fusion protein with C-terminal cysteine. The results showed that the mole ratio of the additive to VHH had a significant effect on the consequent response. Mole ratios of 0.07, 0.7, and 7 led to 90% lower, 15% higher, and 69% lower responses, respectively, than the response of a positive control in which no additive was used. The background levels observed in any additive conditions were as low as that of a negative control lacking both VHH and the additive. These results indicate the applicability of the thiol-reactive pullulan as a response enhancer to VHH-based ELISA. (C) 2017 Elsevier Ltd. All rights reserved.

The identification of MUC1 tumor-associated Tn antigen (alpha GalpNAc1-O-Ser/Thr) has boosted the development of anticancer vaccines. Combining microarrays and saturation transfer difference NMR, we have characterized the fine-epitope mapping of a MUC1 chemical library (naked and Tn-glycosylated) toward two families of cancer-related monoclonal antibodies (anti-MUC1 and anti-Tn mAbs). Anti-MUC1 mAbs clone VU-3C6 and VU-11E2 recognize naked MUC1-derived peptides and bind GalNAc in a peptide-sequence-dependent manner. In contrast, anti-Tn mAbs clone 8D4 and 14D6 mostly recognize the GalNAc and do not bind naked MUC1-derived peptides. These anti-Tn mAbs show a clear preference for glycopeptides containing the Tn-Ser antigen rather than the Tn-Thr analogue, stressing the role of the underlying amino acid (serine or threonine) in the binding process. The reported strategy can be employed, in general, to unveil the key minimal structural features that modulate antigen-antibody recognition, with particular relevance for the development of Tn-MUC1-based anticancer vaccines.

A series of 20 4'-O-glycosides of the aminoglycoside antibiotic paromomycin were syntheized and evaluated for their ability to inhibit protein synthesis by bacterial, mitochondrial and cytosolic ribosomes. Target selectivity, i.e., inhibition of the bacterial ribosome over eukaryotic mitochondrial and cytosolic ribosomes, which is predictive of antibacterial activity with reduced ototoxicity and systemic toxicity, was greater for the equatorial than for the axial pyranosides, and greater for the D-pentopyranosides than for the L-pentopyranosides and D-hexopyranosides. In particular, 4'-O-,beta-D-xylopyranosyl paromomycin shows antibacterioribosomal activity comparable to that of paromomycin, but is significantly more selective showing considerably reduced affinity for the cytosolic ribosome and for the A1555G mutant mitochondrial ribosome associated with hypersusceptibility to drug-induced. ototoxicity. Compound antibacterioribosomal activity correlates with antibacterial activity, and the,ribosomally more active compounds show activity against Escherichia coli, Klebsiella pneumonia, Enterobacter cloacae, Acinetobacter baumannii, and methicillin-resistant Staphylococcus aureus (MRSA). The paromomycin glycosides retain activity against clinical strains of MRSA that are resistant to paromomycin, which is demonstrated to be a consequence of 4'-O-glycosylation blocking the action of 4'-aminoglycoside nucleotidyl transferases by the use Of recombinant E. coli carrying the specific resistance determinant.

The synthesis of a series of a-trifluoromethylcyclohexanols and analogous trimethylsilyl ethers by addition of the RuppertPrakash reagent to substituted cyclohexanones is presented. A method for the assignment of configuration of such compounds, of related a-trifluoromethylcyclohexylamines and of quaternary trifluoromethyl-substituted carbons is described based on the determination of the (3)J(CH) coupling constant between the fluorine-decoupled (CF3)-C-13 resonance and the vicinal hydrogens. This method is dubbed fluorine-decoupled carbon spectroscopy and abbreviated FDCS. The method is also applied to the configurational assignment of substances bearing mono-, di-, and perfluoroalkyl rather than trifluoromethyl groups. The configuration of all substances was verified by either F-19-H-1 heteronuclear Overhauser spectroscopy (HOESY) or X-ray crystallography. The relative merits of FDCS and HOESY are compared and contrasted. 2J(CH), (3)J(CH), and (4)J(CH) coupling constants to F-19 decoupled CF3 groups in alkenes and arenes have also been determined and should prove to be useful in the structural assignment of trifluoromethylated alkenes and arenes.

The human macrophage galactose-type lectin (MGL) is a key physiological receptor for the carcinoma-associated Tn antigen (GalNAc--1-O-Ser/Thr) in mucins. NMR and modeling-based data on the molecular recognition features of synthetic Tn-bearing glycopeptides by MGL are presented. Cognate epitopes on the sugar and matching key amino acids involved in the interaction were identified by saturation transfer difference (STD) NMR spectroscopy. Only the amino acids close to the glycosylation site in the peptides are involved in lectin contact. Moreover, control experiments with non-glycosylated MUC1 peptides unequivocally showed that the sugar residue is essential for MGL binding, as is Ca2+. NMR data were complemented with molecular dynamics simulations and Corcema-ST to establish a 3D view on the molecular recognition process between Gal, GalNAc, and the Tn-presenting glycopeptides and MGL. Gal and GalNAc have a dual binding mode with opposite trend of the main interaction pattern and the differences in affinity can be explained by additional hydrogen bonds and CH- contacts involving exclusively the NHAc moiety.

Anti-MUC1 monoclonal antibodies (mAbs) are powerful tools that can be used to recognize cancer-related MUC1 molecules, the O-glycosylation status of which is believed to affect binding affinity. We demonstrate the feasibility of using a rapid screening methodology to elucidate those effects. The approach involves i) " one-bead-one-compound"- based preparation of bilayer resins carrying glycopeptides on the shell and mass-tag tripeptides coding Oglycan patterns in the core, ii) on-resin screening with an anti-MUC1 mAb, iii) separating positive resins by utilizing secondary antibody conjugation with magnetic beads, and (iv) decoding the mass-tag that is detached from the positive resins pool by using mass spectrometric analysis. We tested a small library consisting of 27 MUC1 glycopeptides with different O-glycosylations against anti-MUC1 mAb clone VU-3C6. Qualitative mass-tag analysis showed that increasing the number of glycans leads to an increase in the binding affinity. Six glycopeptides selected from the library were validated by using a microarray-based assay. Our screening provides valuable information on O-glycosylations of epitopes leading to high affinity with mAb.

A series of 4'-O-glycopyranosyl paromomycin analogs and a 4'-O-(glucosyloxymethyl) analog were synthesized and evaluated for their ribosomal activity to determine the influence of the glycosyl moiety on drug activity and selectivity. Antibacterial activity against clinical strains of Escherichia coli and Staphylococcus aureus was also investigated. White all compounds were less active than paromomycin itself, differences in activity were seen between the gluco-, manno-, and galactopyranosyl series and between individual anomers. These differences in activity, which are discussed in terms of variations in affinity for the ribosomal decoding A site, may prove useful in the design of subsequent generations of improved aminoglycoside antibiotics with reduced toxicity.

Background: Human serum MUC1 peptide fragments bearing aberrant O-glycans are secreted from columnar epithelial cell surfaces and known as clinically important serum biomarkers for the epithelial carcinoma when a specific monoclonal antibody can probe disease-relevant epitopes. Despite the growing importance of MUC1 glycopeptides as biomarkers, the precise epitopes of most anti-MUC1 monoclonal antibodies remains unclear.
Methods: A novel protocol for the fabrication of versatile microarray displaying peptide/glycopeptide library was investigated for the construction of highly sensitive and accurate epitope mapping assay of various anti-MUC1 antibodies.
Results: Selective imine-coupling between aminooxy-functionalized methaciylic copolymer with phosphorylcholine unit and synthetic MUC1 glycopeptides-capped by a ketone linker at N-terminus provided a facile and seamless protocol for the preparation of glycopeptides microarray platform. It was demonstrated that anti-KL-6 monoclonal antibody shows an extremely specific and strong binding affinity toward MUC1 fragments carrying sialyl T antigen (Neu5Ac alpha 2,3Gal beta 1,3GalNAc alpha 1 ->) at Pro-Asp-Thr-Arg motif when compared with other seven anti-MUD monoclonal antibodies such as VU-3D, VU-12E1, VU-11E2, Ma552, VU-3C6, SM3, and DF3. The present microarray also uncovered the occurrence of IgG autoantibodies in healthy human sera that bind specifically with sialyl T antigen attached at five potential O-glycosylation sites of MUD tandem repeats.
Conclusion: We established a straightforward strategy toward the standardized microarray platform allowing highly sensitive and accurate epitope mapping analysis by reducing the background noise due to nonspecific protein adsorption.
General significance: The present approach would greatly accelerate the discovery research of new class autoantibodies as well as the development of therapeutic mAbs reacting specifically with disease-relevant epitopes. (C) 2013 Elsevier B.V. All rights reserved.

Functionalized, high-generation (G7) polyamidoamine (PAMAM) dendrimers are a convenient scaffold for the fully automated enzymatic synthesis of oligosaccharides such as biologically important sialyl Lewis X tetrasaccharide derivatives. In this study, we expanded this strategy to the synthesis of more complicated glycopeptides by assessing the feasibility of G7 PAMAM dendrimer-based polymer supports for attaching glycopeptide intermediates during the subsequent enzymatic modification steps. A monosaccharide-attached glycopeptide containing an N-terminal heterobifunctional linker was prepared by microwave-assisted solid-phase synthesis and was coupled with an aminooxy-functionalized G7 PAMAM dendrimer through oxime bond formation. This reaction proceeded smoothly at pH 4 and afforded the conjugates in 98% yield when 0.2 equivalents of the glycopeptide were combined with 1 equivalent of the aminooxy group of dendrimer. Although modifications using recombinant human β1,4-galactosyltransferase/uridine-5'-diphospho-α-D-galactose disodium salt and recombinant rat α2,3-sialyltransferase/cytidine-5'- monophospho-β-D-N-acetylneuraminic acid disodium salt gave the trisaccharide Neu5Acα2,3Galβ1,4GlcNAc in quantitative yields, treatment with recombinant human α1,3-fucosyltransferase in the presence of excess guanosine 5'-diphospho-β-L-fucose disodium salt did not convert this trisaccharide into the tetrasaccharide sialyl Lewis X tetrasaccharide on the dendrimer. Further optimization studies are required to improve the efficiency of branched-type sugar elongations and product release from polymers by selective peptidases for constructing a high-throughput glycopeptide synthetic system. © 2013 The Society of Polymer Science, Japan (SPSJ) All rights reserved.

Microwave-assisted solid-phase synthesis allows for the rapid and large-scale preparation and structureactivity characterization of tandem repeating glycopeptides, namely monodispersed synthetic antifreeze glycopeptides (syAFGPs, H-[Ala-Thr(Gal1,3GalNAc1)-Ala]n-OH, n=26). By employing novel AFGP analogues, we have demonstrated that of the monodispersed syAFGPn (n=26, degree of polymerization, DP=26, Mw=12573690Da), syAFGP5 (DP=5, Mw=3082Da) and syAFGP6 (DP=6, Mw=3690Da) exhibit the ability to form typical hexagonal bipyramidal ice crystals and satisfactory thermal hysteresis activity. Structural characterization by NMR and CD spectroscopy revealed that syAFGP6 forms a typical poly-L-proline typeII helix-like structure in aqueous solution whereas enzymatic modification by sialic acid of the residues at the C-3 positions of the nonreducing Gal residues disturbs this conformation and eliminates the antifreeze activity.

A macrocyclic mechanism-based inhibitor for neuraminidases (NAs) bearing a 2-difluoromethylphenyl aglycone and a linker between the aglycone and C-9 positions of sialic acid was synthesized and evaluated. The macrocyclic structure was designed to keep the aglycone moiety in the active site of the neuraminidase after cleavage of the glycoside bond. When Vibrio chorelae neuraminidase (VCNA) was treated with a similar acyclic derivative in the presence of detergent, the irreversible inhibition property was disabled. In contrast, this macrocyclic compound acted as an irreversible inhibitor for VCNA in the presence of detergent. Inhibition assay for various NAs using this macrocyclic compound revealed that the irreversible inhibition property depends on the kcat of the neuraminidase treated. NAs having small kcat values, such as Influenza viruses, Clostridium, Trypanosoma cruzi, and Human, were also inhibited irreversibly. However, Salmonella typhimurium NA, which has an extremely high kcat, was not affected irreversibly by the inhibitor. Interestingly, in contrast to common kcat inhibitors, the irreversibility of inhibition by this macrocyclic compound is inversely proportional to the kcat of the target neuraminidase.

Protein O-glycosylation is an essential step for controlling structure and biological functions of glycoproteins involving differentiation, cell adhesion, immune response, inflammation, and tumorigenesis and metastasis. This study provides evidence of site-specific structural alteration induced during multiple sialylation at Ser/Thr residues of the tandem repeats in human MUC1 glycoprotein. Systematic nuclear magnetic resonance (NMR) study revealed that sialylation of the MUC1 tandem repeating glycopeptide, Pro-Pro-Ala-His-Gly-Val-Thr-Ser-Ala-Pro-Asp-Thr-Arg-Pro-Ala-Pro-Gly-Ser-Thr-Ala with core 2-type O-glycans at five potential glycosylation sites, afforded a specific conformational change at one of the most important cancer-relevant epitopes (Pro-Asp-Thr-Arg). This result indicates that disease-relevant epitope structures of human epithelial cell surface mucins can be altered both by the introduction of an inner GalNAc residue and by the distal sialylation in a peptide sequence-dependent manner. These data demonstrate the feasibility of NMR-based structural characterization of glycopeptides synthesized in a chemical and enzymatic manner in examining the conformational impact of the distal glycosylation at multiple O-glycosylation sites of mucin-like domains.

A standardized and smooth protocol for solid-phase glycopeptides synthesis under microwave irradiation was developed. Double activation system was proved to allow for highly efficient coupling of Tn-Ser/Thr and bulky core 2-Ser/Thr derivatives. Versatility and robustness of the present strategy was demonstrated by constructing a Mucine-1 (MUC1) fragment and glycosylated fragments of tau protein. The success of this approach relies on the combination of microwave energy, a resin consisting totally of polyethylene glycol, a low excess of sugar amino acid and the "double activation" method.

Despite the growing importance of mucin core O-glycosylation in many biological processes including the protection of epithelial cell surfaces, the immune response, cell adhesion, inflammation, and tumorigenesis/metastasis, the regulation mechanism and conformational significance of the multiple introduction of alpha-GalNAc residues by UDP-GalNAc: polypeptide N-acetylgalactosaminyltransferases (ppGalNAcTs) remains unclear. Here we report an efficient approach by combining MS and NMR spectroscopy that allows for the identification of O-glycosylation site(s) and the effect of O-glycosylation on the peptide backbone structures during enzymatic mucin domain assembly by using an isoform UDP-GalNAc: polypeptide N-acetylgalactosaminyltransferase-T2 (ppGalNAcT2) in vitro. An electron-capture dissociation device in a linear radio-frequency quadrupole ion trap (RFQ-ECD) combined with a time-of-flight (TOF) mass spectrometer was employed for the identification of Thr/Ser residues occupied by alpha-GalNAc branching among multiple and potential O-glycosylation sites in the tandem repeats of human mucin glycoproteins MUC4 (Thr-Ser-Ser-Ala-Ser-Thr-Gly-His-Ala-Thr-Pro-Leu-Pro-Val-Thr-Asp) and MUC5AC (Pro-Thr-Thr-Val-Gly-Ser-Thr-Thr-Val-Gly). In the present study, O-glycosylation was initiated specifically at Thr10 in naked MUC4 peptide and additional introduction of alpha-GalNAc proceeded preferentially but randomly at three other Thr residues to afford densely glycosylated MUC4 containing six alpha-GalNAc residues at Thr1, Ser2, Ser5, Thr6, Thr10, and Thr15. On the contrary, O-glycosylation of naked MUC5AC peptide occurred predominantly at consecutive Thr residues and led to MUC5AC with four alpha-GalNAc residues at Thr2, Thr3, Thr7, and Thr8. The solution structures determined by NMR spectroscopic studies elicited that the preferential introduction of alpha-GalNAc at Thr10 of MUC4 stabilizes specifically a beta-like extended backbone structure at this area, whereas other synthetic models with a single alpha-GalNAc residue at Thr1, Thr6, or Thr15 did not exhibit any converged three-dimensional structure at the proximal peptide moiety. Such conformational impact on the underlying peptides was proved to be remarkable in the glycosylation at the consecutive Thr residues of MUC5AC.

Despite the growing importance of synthetic glycans as tools for biological studies and drug discovery, a lack of common methods for the routine synthesis remains a major obstacle. We have developed a new method for automated glycan synthesis that employs the enzymatic approach and a dendrimer as an ideal support within the chemical process. Recovery tests using a hollow fiber ultrafiltration module have revealed that monodisperse G6 (MW = 58 kDa) and G7 (MW = 116 kDa) poly(amidoamine) dendrimers exhibit a similar profile to BSA (MW = 66 kDa). Characteristics of the globular protein-like G7 dendrimer with high solubility and low viscosity in water greatly enhanced throughput and efficiency in automated synthesis while random polyacrylamide-based supports entail significant loss during the repetitive reaction/separation step. The present protocol allowed for the fully automated enzymatic synthesis of sialyl Lewis X tetrasaccharide derivatives over a period of 4 days in 16% overall yield from a simple N-acetyl-D-glucosamine linked to an aminooxy-functionalized G7 dendrimer.

Despite increasing importance of protein glycosylation, most of the large-scale glycoproteomics have been limited to profiling the sites of N-glycosylation. However, in-depth knowledge of protein glycosylation to uncover functions and their clinical applications requires quantitative glycoproteomics eliciting both peptide and glycan sequences concurrently. Here we describe a novel strategy for the multiplexed quantitative mouse serum glycoproteomics based on a specific chemical ligation, namely, reverse glycoblotting technique, focusing sialic acids and multiple reaction monitoring (MRM). LC-MS/MS analysis of de-glycosylated peptides identified 270 mouse serum peptides (95 glycoproteins) as sialylated glycopeptides, of which 67 glycopeptides were fully characterized by MS/MS analyses in a straightforward manner. We revealed the importance of a fragment ion containing innermost N-acetylglucosamine (GlcNAc) residue as MRM transitions regardless the sequence of the peptides. Versatility of the reverse glycoblotting-assisted MRM assays was demonstrated by quantitative comparison of 25 targeted glycopeptides from 16 proteins between mice with homo and hetero types of diabetes disease model.

Notch receptors are cell surface glycoproteins that play key roles in a number of developmental cascades in metazoa. The extracellular domains of Notch-1 receptors are composed of 36 tandem epidermal growth factor (EGF)-like repeats, many of which are modified at highly conserved consensus sites by an unusual form of O-glycan, with O-fucose. The O-fucose residues on certain EGF repeats may be elongated. In mammalian cells this can be a tetrasaccharide, Sia alpha 2,3Gal beta 1,4GlcNAc beta 1,3Fuc alpha 1 ->. This elongation process is initiated by the action of O-fucose-specific beta 1,3 N-acetylglucosaminyltransferases of the Fringe family. There is evidence that the addition of GlcNAc by Fringe serves as an essential modulator of the interaction of Notch with its ligands and the triggering of activation. Here we describe the efficient synthesis, folding, and structural characterization of EGF repeat 12 (EGF 12) of a mouse Notch-1 receptor bearing different O-fucose glycan chains. We demonstrate that the three disulfide bonds, Cys(456)-Cys(467) (C1-C3), Cys(461)-Cys(476) (C2-C4), and Cys(478)-Cys(487) (C5-C6) were correctly formed in the nonglycosylated as well as the O-fucosylated forms of EGF 12. Three-dimensional structural studies by NMR reveal that the methyl group of fucose is in close contact with ILe(475), Met(477), Pro(478) residues and this stabilizes the conformation of the antiparallel beta-sheet of EGF 12. The addition of the GlcNAc residue on O-fucosylated EGF 12 induces a significant conformational change in the adjacent tripeptide sequence, Gln(462)Asn(463)Asp(464), which is a motif involved in the natural, enzymatic O-fucosylation at the conserved site (Cys(461)X(4)Ser/ThrCys(467)).

UDP-GalNAc:polypeptide alpha-N-acetylgalactosaminyltransferases (ppGalNAcTs, EC 2.4.1.41), a family of key enzymes that initiate posttranslational modification with O-glycans in mucin synthesis by introduction of alpha-GalNAc residues, are structurally composed of a catalytic domain and a lectin domain. It has been known that multiple Ser/Thr residues are assigned in common mucin glycoproteins as potential O-glycosylation sites and more than 20 distinct isoforms of this enzyme family contribute to produce densely O-glycosylated mucin glycoproteins. However, it seems that the functional role of the lectin domain of ppGalNAcTs remains unclear. We considered that electron capture dissociation mass spectrometry (ECD-MS), a promising method for highly selective fragmentation at peptide linkages of glycopeptides to generate unique c and z series of ions, should allow for precise structural characterization to uncover the mechanism in O-glycosylation of mucin peptides by ppGalNAcTs. In the present study, it was demonstrated that a system composed of an electrospray source, a linear RFQ ion trap that isolates precursor ions, the ECD device, and a TOF mass spectrometer is a nice tool to identify the preferential O-glycosylation sites without any decomposition of the carbohydrate moiety. It should be noted that electrons used for ECD are accelerated within a range from 1.75 to 9.75 eV depending on the structures of glycopeptides of interest. We revealed for the first time that additional installation of a alpha-GalNAc residue at potential glycosylation sites by ppGalNAcT2 proceeds smoothly in various unnatural glycopeptides having alpha-Man, alpha-Fuc, and beta-Gal residues as well as alpha-GalNAc residues. The results may suggest that ppGalNAcT2 did not differentiate totally presubstituted sugar residues in terms of configuration of functional groups, D-, L-configuration, and even alpha-, beta-stereochemistry at an anomeric carbon atom when relatively short synthetic peptides were employed for the acceptor substrates. Unexpected characteristics of ppGalNAcT2 motivated us to challenge site-directed installation of alpha-GalNAc residues at desired position(s) by protecting some hydroxyl groups of Thr/Ser residues with selectively removable sugars, notably a novel concept as "carbohydrate as protective groups", toward a goal of the systematic chemical and enzymatic synthesis of biologically important mucin glycopeptides.

Human serum Krebs von den Lungen-6 (KL-6) antigen, a high-molecular-weight glycoprotein classified as a polymorphic epithelial mucin (MUC1), is a biomarker of diseases such as interstitial pneumonia, lung adenocarcinoma, breast cancer, colorectal adenocarcinoma, and hepatocellular carcinoma. Anti-KL-6 monoclonal antibody (anti-KL-6 MAb) is therefore a potential diagnostic and therapeutic reagent. Although glycosylation at Thr/Ser residues of the tandem-repeating MUC1 peptides appears to determine the disease-associated antigenic structures of KL-6, an essential epitope structure recognized by anti-KL-6 MAb remains unclear. In the present study, a novel compound library of synthetic MUC1 glycopeptides allowed the first rapid and precise evaluation of the specific epitope structure of anti-KL-6 MAb by combined use of a tailored glycopeptides library and common ELISA protocol. We demonstrated that the minimal antigenic structure, an essential epitope, recognized by anti-KL-6 MAb is a heptapeptide sequence Pro-Asp-Thr-Arg-Pro-Ala-Pro (PDTRPAP), in which the Thr residue is modified by Neu5Ac alpha 2,3Gal beta 1,3GalNAc alpha (2,3-sialyl T antigen, core 1-type O-glycan). Anti-KL-6 MAb did not bind with other tumor-relevant antigens, such as GalNA alpha(Tn), Neu5Ac alpha 2,6GalNAc alpha(STn), and Gal beta 1,3GalNAc alpha (T), except for Neu5Ac alpha 2,3Gal beta 1,3(Neu5Ac alpha 2,6) GalNAc alpha(2,3/2,6-disialyl T). However, anti-KL-6 MAb could not differentiate the above minimal antigenic glycopepticle from some core 2-based glycopeptides involving this crucial epitope structure and showed a similar binding affinity toward these compounds, indicating that branching at the O-6 position of GalNAc residue does not influence the interaction of anti-KL-6 MAb with some MUC1 glycoproteins involving an essential epitope. Actually, anti-KL-6 MAb reacts with 2,3/2,6-disialyl T having a 2,3-sialyl T component. This is why anti-KL-6 MAb often reacts with various kinds of tumor-derived MUC1 glycoproteins as well as a clinically important MUC1 glycoprotein biomarker of interstitial pneumonia, namely KL-6, originally discovered as a circulating pulmonary adenocarcinoma-associated antigen. In other words, combined use of anti-KL-6 MAb and some probes that can differentiate the sugars substituted at the O-6 position of the GalNAc residue in MUC1 glycopeptides including the PDTRPAP sequence might be a promising diagnostic protocol for individual disease-specific biomarkers. It was also revealed that glycosylation at neighboring Thr/Ser residues outside the immunodominant PDTRPAP motif strongly influences the interaction between anti-KL-6 MAb and MUC1 glycopeptides involving the identified epitope. Our novel strategy will greatly facilitate the processes for the identification of the tumor-specific and strong epitopes of various known anti-MUC1 MAbs and allow for their practical application in the generation of improved antibody immunotherapeutics, diagnostics, and MUC1-based cancer vaccines.

An efficient protocol for the construction of MUC1-related glycopeptide analogues having complex O-glycan and N-glycan chains was established by integrating chemical and enzymatic approaches on the functional polymer platforms. We demonstrated the feasibility of sortase A-mediated ligation between two glycopeptide segments by tagging with signal peptides, LPKTGLR and GG, at each C- or N-terminal position. Structural analysis of the macromolecular N,O-glycopeptides was performed by means of ESI-TOFMS (MS/MS) equipped with an electron-captured dissociation device. Immunological assay using MUC1 glycopeptides synthesized in this study revealed that N-glycosylation near the antigenic O-glycosylated PDTR motif did not disturb the interaction between the anti-MUC1 monoclonal antibody and this crucial O-glycopeptide moiety. NMR study indicated that the N-terminal immunodominant region [Ala-ProAsp-Thr(O-glycan)-Arg] forms an inverse gamma-turn-like structure, while the C-terminal region composed of N-glycopeptide and linker SrtA-peptide was proved to be an independently random structure. These results indicate that the bulky O- and N-glycan chains can function independently as disease-relevant epitopes and ligands for carbohydrate-binding proteins, when both are combined by an artificial intervening peptide having a possible effect of separating N- and C-terminal regions. The present strategy will greatly facilitate rapid synthesis of multiply functionalized complex neoglycopeptides as new types of convenient tools or models for the investigation of the structure-function relationship of various glycoproteins and development of novel class glycopeptide-based biopharmaceuticals, drug delivery systems, and biomedical materials.

The efficiency of cyclodextrins (CDs), alpha-CD, beta-CD and gamma-CD, for the blotting of hydrophobic substrates to water-soluble polymers and for the synthesis of neoglycolipids using glycosyltransferase is described. CDs did not disturb HPLC purification and did not bring lather. These merits are superior to surfactants commonly used in such a case. The utility of CDs as a novel and efficient supporting material for enzymatic glycosylation is also discussed. (C) 2008 Elsevier Ltd. All rights reserved.

We have established a facile and efficient protocol for the preparative-scale synthesis of various compound libraries related to lactosaminoglycans: cell surface oligosaccharides composed of N-acetyllactosamine as a repeating disaccharide unit, based on chemical and enzymatic approaches. Substrate specificity and feasibility of a bacterial glycosyltransferase, Neisseria meningitidis beta 1,3-N-acetylglucosaminyltransferase (LgtA), were investigated in order to synthesize various key intermediates suited for the construction of mammalian O-glycopeptides and glycosphingolipids containing poly-N-acetyllactosamine structures. Recombinant LgtA exhibited the highest glycosyltransferase activity with strongly basic conditions (pH = 10, glycine-NaOH buffer) and a broad range of optimal temperatures from 20 to 30 C. Interestingly, it was found that LgtA discriminates L-serine and L-threonine and functions both as a core-1 beta 1,3-N-acetylglucosaminyltransferase and core-2 beta 1,3-N-acetylglucosaminyltransferase toward Fmoc-Ser derivatives, while LgtA showed only core-2 beta 1,3-N-acetylglucosaminyltransferase activity in the presence of Fmoc-Thr derivatives. Combined use of LgtA with human beta 1,4-galactosyltransferase allowed for controlled sugar extension reactions from synthetic sugar amino acids and gave synthetic lactosaminoglycans, such as a decasaccharide derivative, Gal,(1 -> 4) GlcNAc beta(1 -> 3) Gal beta(1 -> 4) GlcNAc beta( 1 -> 3) Gal beta(1 -> 4) GlcNAc beta(1 -> 3) Ga beta(1 -> 4) GlcNAc beta(1 -> 6)[Gal beta(1 -> 3)] GalNAc alpha 1 f Fmoc-Ser-OH (6), and a dodecasaccharide derivative, Gal beta( 1 f 4) GlcNAc beta(1 -> 3) Gal beta( 1 -> 4) GlcNAc beta(1 -> 3) Gal beta(1 -> 4)GlcNAc beta(1 -> 6)[Gal beta(1 -> 4) GlcNAc beta(1 -> 3) Gal beta(1 -> 4) GlcNAc beta(1 -> 3) Gal beta(1 -> 3)] GalNAc alpha 1 f Fmoc-Ser-OH(9). A partially protected pentasaccharide intermediate, GlcNAc beta(1 -> 3) Gal beta(1 -> 4)GlcNAc,(1 -> 6)[Gal beta(1 -> 3)] GalNAc alpha 1 -> Fmoc-Thr-OH (11), was applied for the microwave-assisted solid-phase synthesis of a MUC1-related glycopeptide 19 (MW = 2610.1). The findings suggest that this sugar extension strategy can be employed for the modification of lactosyl ceramide mimetic polymers to afford convenient precursors for the synthesis of various glycosphingolipids.

A MUCI-related glycopeptide having five core-2 hexasaccharide branches C330H527N46O207, MW = 8450.9) was synthesized by a new strategy using a combination of microwave-assisted solid-phase synthesis (MA-SPGS) and enzymatic sugar elongation. Synthesis of a key glycopeptide intermediate was best achieved in a combination of PEGA [poly(ethylene glycol)-poly-(NN-dimethylacrylamide) copolymer] resin and MA-SPGS using glycosylated amino acid building blocks with high speed and high purity. Deprotection of the glycopeptide intermediate and subsequent glycosyltransferase-catalyzed sugar elongations were performed for generation of the additional diversities with the sugar moieties of glycopeptides using beta 1,4-galactosyltransferase (beta 1,4-GaIT) and two kinds of alpha 2,3-sialyltransferases [ST3Gal III; alpha 2,3-(N)-SiaT and ST3Gal II; alpha 2,3-(O)-SiaT]. These reactions proceeded successfully in the presence of 0.2% Triton X-100 to convert the chemically synthesized trisaccharide glycans to disialylated hexasaccharide.

Coupling of glycosylated Fmoc-Thr or Fmoc-Ser with N-terminal amino acids on a resin proceeded smoothly under microwave irradiation for 20 min with much higher efficiency (98% yield per coupling) than found in more general conditions. Compared with a conventional protocol, the present method greatly reduces the time required for solid-phase glycopeptide synthesis from 4 days to 7 h, as is the case with the synthesis of Muc-1-related 20-residue glycopeptide carrying five core-2 trisaccharide chains.

Although microwave irradiation has been used in chemical reactions as an efficient heating tool since 1986, we have found that microwave also contribute other factors while studying carbohydrate-related syntheses. 1) With microwave irradiation under Lewis acid conditions, methyl glycosides could behave as glycosyl donors. 2) In a case of synthesis Lewis X, microwave irradiation even at low temperatures was very effective as reducing byproducts and side-reactions. Especially, galactosylation for 4-OH in a fucosyl glucosamine acceptor has proceeded in high yield without producing byproducts, e.g., cleavage of the fucosyl bond or nucleophilic rearrangement of methylthio group. 3) Based on a preliminary study of microwave effect for coupling Fmoc-threonine having acetylated-Core2 to alanine onto supported resin, we successfully synthesized oligopeptide which consisted of twenty of amino acid residues with five of trisaccharides, a partial structure of MUC1 glycoprotein, in shorter time and higher yields. In addition, we also revealed that benzyl protection of glutamic acid was not suitable for basic microwave condition. 4) Microwave could activate azido groups and resulted to accelerate reductions by PPh_3 and Staudinger Ligations.

The mucin-type glycoprotein MUC1 is known to be aberrant glycosylated in various cancer cells. We report the efficient method for the syntheses of MUC1-related glycopeptides having different sugar chains based on core2-type trisaccharide structure by combination of microwave-assisted solid-phase syntheses and enzymatic sugar elongation. Characterizations by MUC1 antibody assay will also be discussed.

In this study, we have developed a prodrug with a mechanism for the release of anti-influenza drugs by the action of neuraminidase, the sialic acid degrading enzyme of the influenza virus. A drug block and a neuraminidase-sensitive sialic acid block were synthesized and linked to form a desired prodrug. When the prodrug was subjected to the action of neuraminidase, hydrolysis of the sialic acid occurred first, followed by spontaneous degradation of the linker connecting the sialic acid and the drug, and finally the drug was observed to be released.

In this study, a mechanism to release an amine-containing compound by the action of neuraminidase has been constructed and applied to a chromogenic substrate and a lipid-soluble peptide. In the presence of neuraminidase, the prodrug-type substrates not only release amine-containing compounds but also reduce the activity of neuraminidase by side reaction with the intermediate generated in the process of release.
