A series of alkyl thioglycosides and alkyl thiodiglycosides bearing glucose and N-acetylglucosamine residues were prepd. by thiol-ene coupling in moderate to good yields (40-85%). Their binding ability towards wheat germ agglutinin was measured by competitive enzyme-linked lectin assays. One of the synthetic compds. presenting two GlcNAc units showed the highest inhibitory effect of this study with an IC50 of 11 μM corresponding to a 3182-fold improvement compared to GlcNAc. These synthetic mols. were used to produce giant vesicles, alone or in mixt. with phospholipids, mimicking bacterial outer membrane vesicles (OMV) with potential antiadhesive properties.
