1H-1,2,3-Triazol-1-yl thiodigalactoside derivatives as high affinity galectin-3 inhibitors
Galactose C3-triazole derivatives were synthesized by Cu(I)-catalyzed cycloaddition between acetylenes and galactose C3-azido derivatives. Evaluation against galectin-3, 7, 8N (N-terminal) and 9N (N-terminal) revealed 1,4-disubstituted triazoles to be high-affinity inhibitors of galectin-3 with selectivity over galectin-7, 8N, and 9N. Conformational analysis of 1,4-di-and 1,4,5-tri-substituted gal
