Résumé :
Most glycosylation reactions are performed by mixing the glycosyl donor and acceptor together followed by the addition of a promoter. While many oligosaccharides have been synthesized successfully using this premixed strategy, extensive protective group manipulation and aglycon adjustment often need to be performed on oligosaccharide intermediates, which lower the overall synthetic efficiency. Preactivation-based glycosylation refers to strategies where the glycosyl donor is activated by a promoter in the absence of an acceptor. The subsequent acceptor addition then leads to the formation of the glycoside product. As donor activation and glycosylation are carried out in two distinct steps, unique chemoselectivities can be obtained. Successful glycosylation can be performed independent of anomeric reactivities of the building blocks. In addition, one-pot protocols have been developed that have enabled multiple-step glycosylations in the same reaction flask without the need for intermediate purification. Complex glycans containing both 1,2-cis and 1,2-trans linkages, branched oligosaccharides, uronic acids, sialic acids, modifications such as sulfate esters and deoxy glycosides have been successfully synthesized. The preactivation-based chemoselective glycosylation is a powerful strategy for oligosaccharide assembly complementing the more traditional premixed method.

Résumé :
The cell microenvironment plays a pivotal role in mediating cell adhesion, survival, and proliferation in physiological and pathological states. The relevance of extracellular matrix (ECM) proteins in cell fate control is an important issue to take into consideration for both tissue engineering and cell biology studies. The glycosylation of ECM proteins remains, however, largely unexplored. In order to investigate the physio-pathological effects of differential ECM glycosylation, the design of affordable chemoselective methods for ECM components glycosylation is desirable. We will describe a new chemoselective glycosylation approach exploitable in aqueous media and on non-protected substrates, allowing rapid access to glyco-functionalized biomaterials.

Résumé :
Purpose: The [18F]-fluorodeoxyglucose ([18F]-FDG) is known to be one of the most used radio-pharmaceuticals for positron emission tomography. [18F]-FDG allows the assessment of glycolytic activity, which is more enhanced in tumor cells than in normal cells. It is also used in the assessment of heart and neurological diseases. The aim of our work is to follow the possibility of modifying [18F]-fluorodeoxyglucose and to develop an indirect radiofluorination procedure applicable under standard clinical conditions. Material/Methods: In the clinic of nuclear medicine at the University Hospital Sta. Marina-Varna, for routine clinical purposes, [18F]-FDG is produced by the nucleophilic method of fluorination, using mannose triflate as a precursor. In addition to being used as a universal radiopharmaceutical, [18F]-FDG may be involved as a prosthetic group in biorthogonal reactions. [18F]-glycosylation by oxime or hydrazone formation is a chemoselective method for indirect radiofluorination of sensitive molecules. The process can improve the pharmacokinetics and stability of the labeled compounds in the blood. Results: We developed a method for modifying fluorine-deoxyglucose by forming a hydrazone bond with bifunctional tetrazine {3-[4-(6-phenyl-[1,2,4,5]-tetrazine-3-yl)-phenoxy]-propyl}-hydrazine) (Tz). The progress of the process and the product obtained were monitored by radio TLC. The radiolabeled tetrazine product will be used for future biorthogonal click reactions with trans-cyclooctene under physiological conditions.

Résumé :
9 Background: While the importance of glycosylation in many cancers is well established, the use of glycomics in biomarker research has lagged behind genomics and proteomics. This is due, in part, to the lack of practical platforms capable of analyzing clinically relevant sample numbers. To address these challenges, we have developed a novel glycomics technology (the GlycanMap platform) that combines a high-throughput assay with custom bioinformatics and rapidly provides both biomarker candidates and information on the underlying biology. Methods: N-glycans were enzymatically released from their parent glycoproteins and captured on chemoselective beads. After washing to remove non-glycan components, purified glycans were derivatized to stabilize labile sialic acids and released from the beads. The steps described above were automated on a 96-well format robotics system to maximize throughput and reduce variability and can be performed in less than 24 hours. Released glycans were analyzed by MALDI-TOF MS using internal standards to facilitate quantitation. In addition to comparing individual glycans between groups, glycan changes were also analyzed with respect to known glycan biosynthetic pathways. Results: The automated assay was compatible with multiple biological sample types, including serum/plasma, tissue, and cell lysates. Human serum was used to assess assay performance and yielded 50-60 glycans with CVs of 10-15% and good linearity. The lower limit of detection was approximately 100 nM. The assay was applied to drug-treated colon cancer cells (HCT116) and revealed significant (> 2-fold) changes in 17 glycans. Projection of these glycan changes on the known N-glycan pathway showed that the most significant changes occurred in the medial-Golgi. Conclusions: We have developed and optimized a high-throughput glycomics platform to facilitate large-scale biomarker studies and assured its practical performance in terms of sensitivity, repeatability, and linearity. Application of this assay to drug-treated colon cancer cells demonstrated that projection of individual glycan changes against known glycan pathways provided additional information about biological mechanism and relevance.

Résumé :
Pseudomonas aeruginosa is a highly prevalent gram-negative bacterium that is becoming more difficult to treat because of increasing antibiotic resistance. As chemotherapeutic treatment options diminish, there is an increased need for vaccines. However, the creation of an effective P. aeruginosa vaccine has been elusive despite intensive efforts. Thus, new paradigms for vaccine antigens should be explored to develop effective vaccines. In these studies, we have focused on the synthesis of two L-rhamnose–bearing epitopes common to glycoforms I and II of the outer core domain of Pseudomonas aeruginosa lipopolysaccharide, α-L-Rha-(1→6)-α-D-Glc-(1→4)-α-D-GalN-(Ala)-α-aminooxy (3) and α-L-Rha-(1→3)-β-D-Glc-(1→3)-α-D-GalN-(Ala)-α-aminooxy (4), respectively. The target trisaccharides were both prepared starting from a suitably protected galactosamine glycoside, followed by successive deprotection and glycosylation with suitably protected D-glucose and L-rhamnose thioglycosides. Global deprotection resulted in the formation of targets 3 and 4 in 22 and 35% yield each. Care was required to modify basic reaction conditions to avoid early deprotection of the N-oxysuccinamido group. In summary, trisaccharides related to the L-rhamnose–bearing epitopes common to glycoforms I and II of the outer core domain of Pseudomonas aeruginosa lipopolysaccharide have been prepared as their aminooxy glycosides. The latter are expected to be useful in chemoselective oxime-based bioconjugation reactions to form Pseudomonas aeruginosa vaccines.
