the enol intermediate in the reaction catalyzed by typeIIdehydroquinase were synthesized to investigate the effect on the inhibition potency of replacing the oxygen atom in the side chain by a carbon atom. The length and the rigidity of the spacer was also studied. The inhibitory properties of the reported compounds against typeIIdehydroquinase from Mycobacterium tuberculosis and Helicobacter pylori

The present invention is directed to a compound of formula I, its diastereoisomers, its enantiomers or its pharmaceutically acceptable salts or solvates, to procedures of obtaining the same, and use as competitive inhibitors of the third enzyme of the shikimic acid pathway, the type II dehydroquinase.

Herein is described a method of accessing indoleâtriazole and benzothiopheneâtriazole analogues that selectively promote or inhibit biofilm formation by Gram-positive and Gram-negative bacteria. Structure/function studies revealed that the addition of a bromine atom at the 2-position of the indoleâtriazole scaffold altered activity against both Gram-negative and Gram-positive bacteria and could transform a biofilm inhibitor into a biofilm inducer. Isosteric replacement of the indole core by a benzothiophene significantly impaired anti-biofilm activity. A competition assay exposing Escherichia coli to the most potent biofilm inducer and an inhibitor of E. coli biofilm formation was performed. The inducer exhibited the ability to mute the effect of the anti-biofilm compound for this targeted bacterial population.
