additional information new constrained inhibitors of DHDPS identified and tested, time-dependent inhibition and substrate protection, dimethyl 2,2'-benzene-1,3-diylbis[(hydroxyimino)ethanoate] discovered as a relatively potent inhibitor of DHDPS enzyme, validates constrained acyclic-intermediate model as a potential inhibitor lead, modifications of the aromatic ring are possible and may result in improvements in activity Escherichia coli
