organizations, such as the World Health Organization (WHO). The need for research on new drugs that are effective in a shorter treatment time and active against resistant strains still persists. Objective: The objective of this study is to synthesize and evaluate forty-four substituted 2-trifluoromethyl-4-quinolinylhydrazone analogs, as probable inhibitors of Mycobacterium tuberculosis growth. Methods: The anti-mycobacterial

objective of the study was to synthesize and evaluate ten new compounds containing camphor nucleus coupled to quinolinic derivatives as probable inhibitors of sensitive and resistant strains of Mtb growth. The synthesis of the final compounds, 3a-e and 4a-e, was based on the use of intermediates previously obtained, in which the coupling of the camphor nucleus to quinoline derivatives was carried out via
结核病是由结核分枝杆菌(Mtb),也称为科赫杆菌引起的严重传染病。潜伏形式和耐药菌株的参与加剧了情况,使该疾病成为严重的公共卫生问题。该研究的目的是合成和评估十种含有与喹啉衍生物偶联的樟脑核的新化合物,作为结核分枝杆菌敏感和耐药菌株生长的可能抑制剂。最终化合物3a-e和4a-e的合成是基于使用先前获得的中间体,其中樟脑核与喹啉衍生物的偶联是通过收敛路线进行的,这产生了良好的产率( 50-80%)。所有最终化合物均得到充分表征,并确定了化合物 4c 的 3 维分子结构。评估了所有化合物针对 Mtb 菌株的抗分枝杆菌活性,并使用肉汤微量稀释测定 (MTT) 的体外微孔板程序进行细胞毒性测试。化合物 3e 对敏感菌株和耐药菌株最有效,最低抑菌浓度 (MIC) 为 9.5 μM,与一线抗结核药物乙胺丁醇相似。选择最具活性的化合物 3e 是因为它对 Vero 细胞具有潜在活性,并且它在接近 MIC
