pathway is the kinase IspE, and we report here the development and biological evaluation of new ligands for this enzyme from Escherichia coli and Aquifex aeolicus species as model systems for the pathogenic enzymes. The study focuses on analysis of the methylerythritol pocket of the 4-diphosphocytidyl-2-C-methyl-D-erythritol binding site. A series of 5-substituted 1-(thiolan-2-yl)cytosines with increasingly
