this work, I prepared a complete series of mono‑deoxyfluorinated N-acetyllactosamine analogues 1-6. The synthesis of each analogue
required approximately 15 synthetic steps, including deoxyfluorination of monosaccharide precursors, chemical glycosylation and
deprotection. Their binding affinities to the two most explored human galectin-1 and -3 were determined by ELISA and 19F NMR T2-filter
techniques, which enabled the identification of hydroxyl groups, crucial in the non-covalent recognition by galectins. This binding study
also permitted to compare both tested galectins in terms of their substrate specificity, revealing subtle differences, which could be utilized
in the development of selective galectin inhibitors. Furthermore, the series is also a perfect tool to study the molecular origin of recognition
events via epitope-mapping 19F NMR techniques.
