  Tuning the Preference of Thiodigalactoside- and Lactosamine-Based Ligands to Galectin-3 over Galectin-1

  摘要：

  Inhibitors for galectin-1 and -3 were synthesized from thiodigalactoside and lactosamine by derivatization of the galactose C3. Introduction of 4-phenyl-1H-1,2,3-triazol-1-yl substituents at the thiodigalactoside C3 by CuAAC, targeting arginine-arene interactions, increased the affinity to 13 nM but yielded little selectivity. The builder 4-(4-phenoxypheny1)-1H-1,2,3-triazol-1-yl substituent, however, increased the preference for galectin-3 over galectin-1 to more than 200-fold. Modeling showed more arginine-arene interactions for galectin-3 than for galectin-1. Introducing 4-phenoxyaryl groups on lactosamine had a similar effect.
