A series of 19 isonicotinic acid hydrazide derivatives has been synthesized and evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv using alamar blue susceptibility test. The synthesized compounds inhibit Mycobacterium tuberculosis H37Rv strain with minimum inhibitory concentration ranging from (0.00014-0.01174 mM). Among all synthesized compounds seven derivatives 2a, 2b, 2e, 2h, 2l, 2m and 2q were more potent than isoniazid and the compound 2q emerged as the most potent derivative, being more effective than isoniazid with an (MIC 0.00023 mM) in vitro. The results demonstrated the potential and importance of developing new isoniazid derivatives against Mycobacterium infections.
