GangliosideGM3, as well as other gangliosides, offers a variety of modifications in its sialic acid and ceramide moieties GM3 exhibits various types of important biological activities, due to the inability to effectively observe the trafficking of gangliosideGM3, developing sensitive research tools for specific monitoring of GM3 expression and activity is thus desirable. The total synthesis of a

Various pseudo-oligosacchardies and aminoacidglycoconjugates were synthesized via an intermolecular 1,3-dipolar cycloaddition (“click”) reaction using easily accessible carbohydrate and aminoacid derived azides and alkynes as building blocks. It is pertinent to mention that the conjugation reaction is highly regioselective and high yielding and can be carried out under mild reaction conditions.

Carbohydrate microarrays have been used recently for the rapid analysis of glycan-protein or glycan-cell interactions and for the detection of pathogens. As a demonstration of its significance and versatility, the microarray technology has been applied in this effort to assay glycosyltransferase activities. In addition, carbohydrate microarray based methods have been employed to quantitatively determine binding affinities between lectins and carbohydrates.
Design, synthesis and biological evaluation of azithromycin glycosyl derivatives as potential antibacterial agents
A series of 11,12-cyclic carbonate azithromycin-4 ''-O-carbamoyl glycosyl derivatives were designed, synthesized, and evaluated as antibacterial agents to search for target compounds with excellent activity. The results of preliminary antibacterial tests against eight strains in vitro revealed that all of the title compounds exhibited improved activities with broad spectrum compared with the parent compound. The glycosylated side chains may be the pharmacophores responsible for the improved activity. (C) 2013 Elsevier Ltd. All rights reserved.
