AbstractThe present article describes a series of eighteen N-[(E)-(hydroxy, methoxy and ethoxy substitutedphenyl) methylidene]isonicotinohydrazide derivatives, which were synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis, and the activity expressed as the minimum inhibitory concentration (MIC) in μg/ml. Compounds 2a, 2d-f, and 2h exhibited a significant activity (0.31-1.25 μg/ml) when compared with first line drugs such as isoniazid (INH) and rifampicin (RIP) and could be a good start point to find new lead compounds in the fight against multi-drug resistant tuberculosis.
