A series of eight N'-[(E)-(disubstituted-phenyl)methylidene]isonicotino-hydrazide derivatives were synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis, and the activity expressed as the minimum inhibitory concentration (MIC) in mg/mL. Four compounds 2b-d and 2f exhibited a significant activity (0.6 mg/mL), when compared with first line drugs such as isoniazid (INH) and rifampin (RIP) and could be a good starting point to develop new lead compounds in the fight against multidrug resistant tuberculosis.

    Background. There is limited evidence that the DOTS (directly observed therapy, short course) strategy for tuberculosis (TB) control can contain the emergence and spread of drug resistance in the absence of second-line treatment. We compared drug-resistance levels between 1996 and 2001 in the...
