The synthesis of fluorinated C-mannopeptides and their evaluation as E- and P-selectin inhibitors is described. These molecules are difluorinated analogues of CH(2)-glycopeptides already reported to act as sLe(x) mimics. The alpha and beta anomers of these CF(2)-glycopeptides have been prepared, as well as their 1-hydroxy analogues which were present in solution as an equilibrium mixture of alpha- and beta-pyranose and alpha- and beta-furanose forms. These molecules showed inhibitory activities comparable to their CH(2) counterparts with a moderate influence of the pseudo-anomeric center configuration.
