In this work, a complete series of mono-deoxyfluorinated N-acetyllactosamine analogues (6 compounds) have been prepared. The synthesis of each analogue required about 15 synthetic steps, including stereoselective deoxyfluorination of monosaccharide precursors and chemical glycosylation. The binding affinities of the prepared analogues to human gal-1 and gal-3 were determined by ELISA assay and 19F NMR T2-filter techniques. These experiments revealed that individual galectins tolerate fluorine at different positions which makes deoxyfluorinated carbohydrates promising galectin inhibitors.
