Recent development in the design of sialyltransferase inhibitors.

Sialylation at the non-reducing end of glycoconjugates is an important biological process in cellular recognitions, tumor metastases, and immune responses, which are mediated by a family of enzymes known as sialyltransferases. Inhibition of sialyltransferases may prove useful in elucidating the biological functions of sialylation and may have therapeutic applications. This review summarizes the recent development in this field with particular focus on the strategies used for the design of carbohydrate mimetics and the structure-activity relationships of substrate-based sialyltransferase inhibitors.
