prepare various isoniazid derivatives by introducing the isoniazid pharmacophore into several molecules and screening for antimycobacterial activity. Ortho-hydroxy acetophenone reacts with isoniazid to form acid hydrazones. The C-Mannich bases of the above acid hydrazones were prepared by reacting them with formaldehyde and various secondary amines. The synthesized compounds were screened against M. tuberculosis
这项研究的目的是通过将异烟
肼药效团引入几个分子并筛选抗分枝杆菌活性来制备各种异烟

苯乙酮与异烟
肼反应形成酸性。上述酸性acid的C-曼尼希碱是通过使它们与
甲醛和各种仲胺反应制备的。使用艾玛蓝敏感性试验,针对结核分枝杆菌H(37)R(v)筛选合成的化合物。合成的化合物抑制结核分枝杆菌菌株H(37)R(v)的最小抑制浓度范围为0.56至4.61 microM。发现化合物N'-1- [1- [2-羟基-3-(

肼8是活性最高的化合物,MIC为0.56 microM,并且比异烟
肼(MIC为2.04 microM)更有效。治疗10天后,与对照相比,化合物8使鼠肺组织中的细菌负荷降低了3.7-log 10,这与异烟
肼等价。结果表明开发针对分枝杆菌感染的新型异烟
