The difficulty in managing tuberculosis includes the prolonged duration of the treatment, the emergence of drug resistance, and coinfection with HIV/AIDS. Tuberculosis control requires new drugs that act on novel drug targets to help in combating resistant forms of Mycobacterium tuberculosis and reduce the treatment duration. For this purpose, 6-substituted-3(2H)-pyridazinone-2-acetyl-2- (substituted/nonsubstituted acetophenone) hydrazone derivatives were synthesized and their structures were elucidated by elemental analyses, IR, and ^1H-NMR. The in vitro antimycobacterial activities of synthesized compounds 5a-l were determined by the agar proportion method against Mycobacterium tuberculosis H37Rv. Among the target compounds, 5b and 5f exhibited the best antimycobacterial activity, with a MIC value of 5 \mu g/mL.
治疗结核病的困难包括治疗时间过长、抗药性的出现以及合并感染艾滋病毒/艾滋病。结核病的控制需要作用于新型药物靶点的新药,以帮助对抗耐药结核分枝杆菌并缩短治疗时间。 为此,我们合成了 6-取代-3(2H)-哒嗪酮-2-乙酰基-2-(取代/未取代苯乙酮)腙衍生物,并通过元素分析、红外光谱和^1H-NMR 阐明了它们的结构。通过琼脂比例法测定了合成化合物 5a-l 对结核分枝杆菌 H37Rv 的体外抗霉活性。 在目标化合物中,5b 和 5f 表现出最好的抗结核活性,其 MIC 值为 5 \mu g/mL。
