Ethionamide (ETH) is a second-line drug for the treatment of tuberculosis. As a prodrug, ETH has to be activated by EthA. ethA is controlled by its repressor EthR. 2-Phenylethyl-butyrate (2-PEB) inhibits EthR binding, enhances expression of EthA, and thereby enhances the growth-inhibitory effects of ethionamide, isoxyl, and thiacetazone in Mycobacterium tuberculosis strains with resistance to ETH due to inhA promoter mutations but not ethA mutations. ...[more]
