Carbohydrates are involved in many important pathological processes, such as bacterial and viral infections, by means of carbohydrate-protein interactions. Glycoconjugates with multiple carbohydrates are involved in multivalent interactions, thus increasing their binding strengths to proteins. In this work, we report the efficient synthesis of novel muramic and glucuronic acid glycodendrimers as potential Dengue virus antagonists. Aromatic scaffolds functionalized with a terminal ethynyl groups were coupled to muramic and glucuronic acid azides by click chemistry through optimized synthetic strategies to afford the desired glycodendrimers with high yields. Surface Plasmon Resonance studies have demonstrated that the compounds reported bind efficiently to the Dengue virus envelope protein. Molecular modelling studies were carried out to simulate and explain the binding observed. These studies confirm that efficient chemical synthesis of glycodendrimers can be brought about easily offering a versatile strategy to find new active compounds against Dengue virus.

Biological activity of N-acetyl-6-sulfo-β-D-glucosaminides (6-sulfo-GlcNAc 1) having a structural homology to N-acetylneuraminic acid (Neu5Ac 2) and 2-deoxy-2,3-dehydro-N-acetylneuraminic acid (Neu5Ac2en 3) was examined in terms of inhibitory activity against influenza virus sialidase (influenza, A/Memphis/1/71 H3N2). pNP 6-Sulfo-GlcNAc 1a was proved to show substantial activity to inhibit the virus sialidase (IC50=2.8 mM), though p-nitrophenyl (pNP) GlcNAc without 6-sulfo group and pNP 6-sulfo-GlcNH3+ 1b without 2-NHAc showed little activity (IC50 >50 mM). The activity was enhanced nearly 100-fold when the pNP group of 1a was converted to p-acetamidophenyl one 5 (IC50=30 μM) or replaced with 1-naphthyl 6 (IC50=10 μM) or n-propyl one 8 (IC50=11 μM).

Rhizobial bacteria synthesize lipo-chitin oligosaccharide signal molecules (Nod factors) that are essential for the formation of symbiotic organs on the roots of host plants, a process known as nodulation. Biosynthesis of the chitin oligosaccharide moiety
