Toward a transition state analog inhibitor of N-acetylglucosaminyl transferase V

Carbohydrate mimetics-based glycosyltransferase inhibitors

The search for carbohydrate mimetics-based glycosyltransferase inhibitors is a dynamic field that emerged 10 years ago. This review presents a description of the different types of glycosyltransferase inhibitors containing a carbohydrate mimetic (primarily an iminosugar, a carbasugar or a C-glycoside) and data on their biological activity whenever such data are available. The purpose of this account is to foster a synergy between the two expanding research areas of glycomimetics and glycosyltransferases.

Inhibition of chitin synthetase from Saccharomyces cerevisiae by a new UDP-GlcNAc analogue

The synthesis and biological evaluation of a new UDP-GlcNAc competitor (I), designed to mimic the transition state of the sugar donor in the enzymatic reaction catalysed by chitin synthetase, is described. Compound (I) was found to competitively inhibit chitin synthetase from Saccharomyces cerevisiae with respect to UDP-GlcNAc, but displayed minimal antifungal activity.
