MbtI Inhibition studies aid in the future design of [http://psychology.wikia.com/wiki/Antitubercular_drugs anti-tubercular agents] and [http://en.wikipedia.org/wiki/Broad-spectrum_antibiotic broad-spectrum antibiotics] with a novel mode of action.  Mimics of the enzyme-bound intermediate of MbtI, <scene name='69/694235/3sr6_inhibitor/3'>isochorismate</scene>, prove to be significantly more potent inhibitors than mimics of the substrate, chorismate <ref name= "1a"/><ref name="2a"/><ref name="5a"/>. The isochorismate mimic based on a 2,3-dihydroxybenzoate scaffold showed low-micromolar inhibition constants against MbtI that were an order of magnitude more potents than the natural substrates<ref name="2a"/>.
