additional information a transition state mimic is designed for MurG, containing a functionalised proline, linked through the alpha-carboxylic acid, via a spacer, to a uridine nucleoside. A set of 15 functionalised prolines are synthesised, using a convergent dipolar cycloaddition reaction, which are coupled via either a glycine, proline, sarcosine, or diester linkage to the 5'-position of uridine. The library of 18 final compounds are tested as inhibitors of Escherichia coli glycosyltransferase MurG, overview Escherichia coli
