Carbohydrate Triazoles and Isoxazoles as Inhibitors of Galectins‐1 and ‐3.

Galactosides and lactosides bearing triazoles or isoxazoles, regiospecifically prepared by [1,3]-dipolar cycloadditions between alkynes, azides or nitrile oxides, provided specific galectin-1 and -3 inhibitors with potencies as low as 20 µM.
