General description

Ethionamide (ETA, ETH), a thioamide, is an anti-tuberculosis agent used as a second-line therapy in treating tuberculosis when other agents are not effective. The structure of ETA is similar to isoniazid.

Application

Ethionamide is used in antimicrobials and in potency assay of test compounds on M. tuberculosis.

Biochem/physiol Actions

Ethionamide is used as an anti-tuberculosis antibiotic and an inducer of hypothyroidism.

Drug resistance has now posed more severe and emergent threats to human health and infectious disease treatment. However, wet-lab approaches alone to counter drug resistance have so far still achieved limited success due to less knowledge about the underlying mechanisms

A search to identify new mechanisms of isoniazid resistance in Mycobacterium bovis led to the isolation of mutants defective in mycothiol biosynthesis due to mutations in genes coding for the glycosyltransferase (mshA) or the cysteine ligase (mshC). These mutants showed

Ethionamide (ETA) is an important component of second-line therapy for the treatment of multidrug-resistant tuberculosis. Synthesis of radiolabeled ETA and an examination of drug metabolites formed by whole cells of Mycobacterium tuberculosis (MTb) have allowed us to demonstrate that ETA

Mycobacterial transcriptional repressor EthR controls the expression of EthA, the bacterial monooxygenase activating ethionamide, and is thus largely responsible for the low sensitivity of the human pathogen Mycobacterium tuberculosis to this antibiotic.

Ethionamide sugar-coated tablets have been reformulated to film-coated tablets to improve dissolution and stability. The study objective was to compare the bioavailability of the film-coated (test) and sugar-coated (reference) formulations of ethionamide.
