Among them, a seleno-digalactoside (SeDG) substituted with a benzyl group at position 3 of both saccharide residues (benzyl 3,3′-seleno-digalactoside, SeDG-Bn), attracted considerable attention for its selectivity and potent inhibitory efficacy against Gal-3.

This approach revealed the recognized epitope, the binding mode within Gal-3 binding pocket and enabled the generation of a 3D model of the complex.

The digalactose backbone orientation in Gal-3 binding site is partially modified by the benzyl group with respect to complexes with lactosamine and SeDG.
