novel antibiotics. Dehydroquinase is the third enzyme of the pathway, catalyzing the reversible dehydratation of 3-dehydroquinic acid to form 3-dehydroshikimic acid. Here we present the synthesis of novel inhibitors with high affinity for Helicobacter pylori typeIIdehydroquinase and efficient inhibition characteristics. The structure of Helicobacter pylori typeIIdehydroquinase in complex with the

competitive inhibitors of Mycobacterium tuberculosistypeIIdehydroquinase, an essential enzyme in Mycobacterium tuberculosis bacteria, is reported. The inhibitors reported here are mimics of the enol intermediate and the effect of substitution on C2 was studied. The crystal structures of Mycobacterium tuberculosistypeIIdehydroquinase in complex with three of the reported inhibitors are also described
