WebThe disorder is caused by mutations in the GDP-fucose transporter, which limits the synthesis of fucosylated glycans. One of these is sialyl Lewis-X (sLeX), a glycan essential for leukocyte rolling before extravasation. Oral fucose supplements effectively reduced leukocytosis in two patients by allowing synthesis of sufficient sLeX. WebSialyl LewisX (sLeX) is a natural ligand of E-selectin that is overexpressed by inflamed and tumor endothelium. Although sLeX is a potential ligand for drug targeting, synthesis of the tetrasaccharide is complicated with many reaction steps. In this study, structurally simplified novel sLeX analogues were designed and linked with 1,2-distearoyl-sn-glycero-3 …
