In this study, a total of 22 piece quinoline-3-carbaldehyde hydrazone derivative compounds were designed and synthesized, 2 of which were not original, their antimicrobial activities were determined with microdilution method and their in vitro cytotoxic effect was investigated in MCF-7 and A549 cells by MTT assay. When the activity results are examined, although the antimicrobial effects of quinoline derivatives, in general, are weaker than standard drugs; 3q5 and 3q6 against MRSA showed promising activity with MIC:16 µg/ml compared to reference drugs. Compounds generally showed weaker cytotoxic activity on the A549 and MCF-7 cell line. 3q12, 3q17 and 3q22 at 100 µM reduced cell viability to 59.28%, 76.24% and 72.92% on A549 cells, respectively. Compound 3q6, one of the most effective compounds against MRSA, formed a 2.10 Å long hydrogen bond between the quinoline nitrogen and ARG132 in the DNA topoisomerase IV active site (PDB: 3FV5). Theoretical ADME profiles of all compounds comply with Lipinski and other limiting rules. In addition, MEP analysis of 3q6, geometric optimization and molecular reactivity analysis were calculated with the 6-311G (d,p) base set DFT/B3LYP theory, and ΔE = E_LUMO-E_HOMO, which is a measure of the stable structure of the molecule, was calculated as 0.13377 for 3q6 and had the most stable electronic structure among all compounds..

本研究共设计并合成了22种喹啉3-甲醛甲醛carb衍生物，其中2种不是原始化合物，采用微量稀释法确定了它们的抗菌活性，并在MCF-7和7中研究了它们的体外细胞毒性作用。通过MTT测定法检测A549细胞。检查活性结果时，尽管喹啉衍生物的抗菌作用通常比标准药物弱；与参考药物相比，针对MRSA的3q5和3q6在MIC：16 µg / ml方面显示出令人鼓舞的活性。化合物通常对A549和MCF-7细胞系显示较弱的细胞毒活性。3q12、3q17和3q22在100 µM下，A549细胞的细胞活力分别降低至59.28％，76.24％和72.92％。化合物3q6是最有效的抗MRSA化合物之一，在DNA拓扑异构酶IV活性位点（PDB：3FV5）中，在喹啉氮和ARG132之间形成了一个2.10Å长的氢键。所有化合物的理论ADME谱均符合Lipinski和其他限制规则。此外，使用6-311G（d，p）基集DFT / B3LYP理论和ΔE= E _LUMO -E _HOMO计算了3q6的MEP分析，几何优化和分子反应性分析，这是对稳定结构的一种度量该分子的，被计算为0.13377对3q6并具有所有化合物中最稳定的电子结构..
