Abstract
Lectins, carbohydrate-binding proteins, play important functions in all forms of life from bacteria and viruses to plants, animals, and humans, participating in cell-cell communication and pathogen binding. In an attempt to modify lectin functions, artificial lectin ligands were made usually as big dendrimeric or cluster multivalent glycomimetic structures. Here we synthesized a novel set of glycomimetic ligands through protection/deprotection multicomponent reactions (MCR) approach. Multivalent di-and tri-carbohydrate glycomimetics containing D-fructose, D-galactose, and D-allose moieties were prepared in 63-96% yield. MCR glycomimetics demonstrated different binding abilities for plant lectins Con A and UEA I, and human galectin-3. Information gained about the influence of molecule structure, multivalency and optical purity on the lectin binding ability can be used in lectin detection and sensitivity measurements to further facilitate understanding of carbohydrate recognition process.
期刊介绍:
Glycoconjugate Journal publishes articles and reviews on all areas concerned with:
function, composition, structure, biosynthesis, degradation, interactions, recognition and chemo-enzymatic synthesis of glycoconjugates (glycoproteins, glycolipids, oligosaccharides, polysaccharides and proteoglycans), biochemistry, molecular biology, biotechnology, immunology and cell biology of glycoconjugates, aspects related to disease processes (immunological, inflammatory, arthritic infections, metabolic disorders, malignancy, neurological disorders), structural and functional glycomics, glycoimmunology, glycovaccines, organic synthesis of glycoconjugates and the development of methodologies if biologically relevant, glycosylation changes in disease if focused on either the discovery of a novel disease marker or the improved understanding of some basic pathological mechanism, articles on the effects of toxicological agents (alcohol, tobacco, narcotics, environmental agents) on glycosylation, and the use of glycotherapeutics.
Glycoconjugate Journal is the official journal of the International Glycoconjugate Organization, which is responsible for organizing the biennial International Symposia on Glycoconjugates.
