The catalytic site of muscle glycogen phosphorylase b (GPb) has been probed with five fluorine glucose derivatives. These inhibitors had fluorine instead of hydroxyl at the 3′ position of the glucose moiety and a variety of pyrimidine derivatives at the 1′ position. The best of this carbohydrate-based family of five inhibitors displays a K i value of 46 μM.
