This interplay proceeds via the terminal tetrasaccharide sialyl Lewisx (sLex), present on physiological selectin ligands and E- and P-selectins located on the endothelial surface. Blocking this process is regarded as a promising therapeutic approach for inflammatory diseases where excessive leukocyte efflux is responsible for tissue damage. Selectin antagonists are generally based on sLex as lead structure, containing the essential pharmacophores pre-oriented in the bioactive conformation. In this work, we describe a set of competitive sLex mimetics possessing the carboxylic acid pharmacophore equipped with additional hydrophobic substituents as neuraminic acid (Neu5Ac) replacements. This small library of antagonists derived from Huisgen-1,3-dipolar cycloadditions allows to further probe the carbohydrate recognition domain of E-selectin. Magnani, John L. eng
