Abstract:
Galactofuranosylation has been accomplished with 1-bromo-1-deoxy-2,3,5,6-tetra-O-benzoyl-a-D-galactofuranoside in the presence of cadmium carbonate as promotor. Glycosylation agent has been prepared by bromination of penta-O-benzoyl-ab-D-galactofuranoside with a solution of hydrogen bromide in glacial acetic acid. The precursor of the latter reaction has been produced by benzoylation of D-galactose that had been heated in pyridine while still warm. The following hydroxysteroids have been selected as being representative in terms of configuration, type of hybridization of carbon bearing hydroxy

Abstract:
An efficient and improved one-pot method for the synthesis of galactofuranosides via iodine-promoted cyclization of galactose diethyl dithioacetal in the presence of alcohol, acting both as solvent and nucleophile, is described. The reaction is carried out at room temperature. Alcohols, such as methanol, cyclohexanol and tert-butanol, were used as nucleophiles for the reaction using 2%, 3% and 5% iodine promoter, respectively. A key finding in this study was that the iodine-promoted cyclization of galactose diethyl dithioacetal with alcohol led to selective formation of β-galactofuranoside all

Abstract:
Using an indirect method, we have synthesised α-linked carbasugar analogues of galactofuranosides for the first time. Ring opening of a β-talo configured carbasugar 1,2-epoxide by alcohol nucleophiles under Lewis acidic conditions proceeded with very good regioselectivity to give α-talo configured C1-substituted ethers with a free OH-group at the C2 position. Inversion of configuration at C2 by an oxidation–reduction sequence gave the α-galacto configured carbahexofuranose C1 ethers. A carbadisaccharide corresponding to the Galf(α1→3)Manp substructure from Apodus deciduus galactomannan was syn

Their mechanism of action was explored using electron paramagnetic resonance spectroscopy (EPR) and nuclear magnetic resonance (NMR), and ultrastructural alterations were analyzed by transmission electron microscopy (TEM).

Abstract:
Kinetically controlled Fischer glycosidation was achieved under flow conditions. β-Hydroxy-substituted sulfonic acid functionalized silica (HO-SAS) was used as an acid catalyst. This reaction directly converted aldohexoses into kinetically favored furanosides to enable the practical synthesis of furanosides. After optimization of the reaction temperature and residence time, glucofuranosides, galactofuranosides, and mannofuranosides were synthesized in good yields.

Des immunoadjuvants sont ajoutés aux formulations dans le but d’augmenter l’intensité et la durée de la réponse immunitaire. Les glycolipides sont des composés qui possèdent des propriétés immunoadjuvantes puisqu’ils peuvent transporter des agents thérapeutiques et /ou interagir avec les cellules du système immunitaire.

Abstract:
In this thesis, carbohydrate mimicry is investigated through the syntheses of carbohydrate analogues and evaluation of their inhibitory effects on carbohydrate-processing enzymes. Galactofuranosides are interesting structures because they are common motifs in pathogenic microorganisms but not found in mammals. M.tuberculosis, responsible for the disease tuberculosis, has a cell wall containing a repeating unit of alternating (1→5)- and (1→6)-linked β-D-galactofuranosyl residues. Synthetic inhibitors of the enzymes involved in the biosynthesis of the cell wall could find great therapeutic use.

Les leishmanioses affectent chaque année près de 2 millions de personnes dans le monde. Une cible d’intérêt a été découverte dans le glycocalyx du parasite : le LPG, qui semble jouer un rôle important pour sa survie, sa virulence et dans les interactions hôte-parasite. Il est à noter que cet oligosaccharide possède des unités β-D-Galf, motif totalement absent chez les mammifères. Ainsi, la synthèse de mimes du LPG contenant des motifs Galf pourrait conduire à la fabrication de sondes diagnostiques spécifiques au parasite, mais aussi à l’émergence de nouveaux traitements.

La leishmaniose est une maladie tropicale négligée pour laquelle l’arsenal thérapeutique actuel est limité. Ce travail de thèse s’est intéressé à rechercher des nouvelles cibles thérapeutiques en ciblant la paroi des leishmanies. Le lipophosphoglycane (LPG), constituant majoritaire de la paroi, présente un motif glucidique particulier, le galactofuranose, qui semble une cible thérapeutique intéressante car il est absent des membranes de mammifères. Les galactofuranosyl-transférases sont impliquées dans le métabolisme de ce furanose, et ce travail a débuté par l’étude de ces enzymes et par la c
