Description and Uses
Ethionamide is an antimycobacterial compound that is active against M. tuberculosis (MICs = 0.3-1.25 μg/ml). It is activated via oxidation by flavin monooxygenase and inhibits the InhA enzyme involved in mycolic acid biosynthesis. Formulations containing ethionamide have been used in the second-line treatment of multi-drug resistant tuberculosis.
Antibacterial (tuberculostatic).
