Application
Ethionamide: A Thioamide Anti-Tuberculosis Agent
Ethionamide and prothionamide [P2302] are thioamide anti-tuberculosis agents. They have activity against Mycobacterium tuberculosis, Mycobacterium leprae murium and Mycobacterium avium. The precise mechanisms of action remain unknown, but it has been reported that the thioamides are prodrugs that are oxidatively converted to their active forms by the flavin monooxygenase EtaA of Mycobacterium tuberculosis.
