Abstract:

Ethionamide (ETH)/prothionamide (PTH) are analogues of isoniazid (INH). They are usually used as second-line anti-tuberculosis drugs on treatment of multidrug resistant tuberculosis(MDR-TB). The clinical usage of ETH/PTH is affected by their cross resistance with INH, weak bactericidal effect and adverse reactions of digestive system they may induce. In recent years, researches of ETH boosters based on molecular mechanism of ETH/PTH have also made significant progress. In this review, the mechanism of ETH/PTH resistance, the mechanism of INH cross resistance and studies of ETH boosters were summarized.

Key words: Mycobacterium tuberculosis, Isoniazid, Ethionamide, Prothionamide, Tuberculosis,multidrug-resistant, Molecular mechanisms of pharmacological action, Review literature (as topic)
