  Replacement of Carbohydrate Sulfates by Sugar C‐Sulfonic Acid Derivatives

  摘要：

  3'-Substituted p-methoxyphenyl beta-lactosides and one of their 3'-epimer were synthesized. The common feature of these compounds is the presence of a strong negative charge at position C-3' in the form of sulfonic acid moieties. The 3',4'-diol derivative of p-methoxyphenyl lactoside was also glycosylated with the thioglycoside of the sulfoulosonic acid. The two-regioisomeric trisaccharides were isolated but their deprotection failed. The aim of the present study was to find carbohydrate ligand(s), which can inhibit the adhesion between Helicobacter pylori and the gastrointestinal epithelial cells.
