Synthesis and Biological Evaluation of S-Neofucopeptides as E- and P-Selectin Inhibitors.

Abstract 0

The synthesis of /-L-fucosylated cysteamine, 3-thiopropionic acid, and 3-thioacetic acid derivatives as building blocks for the preparation of S-neofucopeptides is shown. These compounds were used in the synthesis of new thiofucosides derivatives (8, 9, 9, 10, 22, 22, 24, 26) that show affinity towards E- and P-selectins. They constitute a new series of hydrolytically stable and low-molecular-weight mimetics of the natural SLex tetrasaccharide.
