are key enzymes in metabolism, pathogenic/antipathogenic mechanisms and normal cellular functions. Recently, a novel approach for glycosidase inhibition that conveys multivalent glycomimetic conjugates has emerged. Many questions regarding the mechanism(s) of multivalent enzyme inhibition remain unanswered. Herein we report the synthesis of a collection of novel homo‐ and heterovalent glyco(mimetic)‐fullerenes

Photorhabdusasymbiotica is a gram‐negative bacterium that is not only as effective an insect pathogen as other members of the genus, but it also causes serious diseases in humans. The recently identified lectinPHL from P. asymbiotica verifiably modulates an immune response of humans and insects, which supports the idea that the lectin might play an important role in the host–pathogen interaction

Fullerene hexakis-adducts bearing 12 peripheral carbohydrate moieties have been prepared by grafting sugar derivatives onto the fullerene core through the copper mediated Huisgen 1,3-dipolar cycloaddition of azides and alkynes.

influence on the binding affinity of the divalent fucosides. The relationship between the EG length and chelate binding efficiency to FleA was explored according to polymer theory. Hexa‐ and octavalent compounds based on cyclodextrin and octameric silsesquioxane scaffolds were nanomolar FleA inhibitors, surpassing their monovalent fucose analogue by more than three orders of magnitude. Importantly, some
