The synthesis of a library of nucleoside triphoshate mimetics is described where the Mg2+ chelated triphosphate sidechain is replaced by an uncharged methylene-triazole linked monosaccharide sidechain. The compounds have been evaluated as inhibitors of Bacillus anthracis pantothenate kinase and a competitive inhibitor has been identified with a K-i that is 3-fold lower than the K-m value of ATP.
