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.
本研究合成了一系列 19 种异烟酸酰肼衍生物,并使用茜草蓝药敏试验评估了它们对结核分枝杆菌 H37Rv 的体外抗结核活性。合成的化合物对结核分枝杆菌 H37Rv 株具有抑制作用,最低抑制浓度为(0.00014-0.01174 mM)。在所有合成的化合物中,7 种衍生物 2a、2b、2e、2h、2l、2m 和 2q 比异烟肼更有效,其中化合物 2q 是最有效的衍生物,其体外抑菌浓度为 0.00023 mM,比异烟肼更有效。研究结果表明,开发新的异烟肼衍生物具有抗分枝杆菌感染的潜力和重要性。
