A series of novel Schiff base derivatives have been designed and synthesized, and their biological activities were also evaluated as potential inhibitors of FabH. These compounds were assayed for antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. Compounds with potent antibacterial activities were tested for their E. coli FabH inhibitory activity. Compound 3v showed the most potent antibacterial activity with MIC of 1.56-6.25 μg/mL against the tested bacterial strains and exhibited the most potent E. coli FabH inhibitory activity with IC(50) of 4.3 μM. Docking simulation was performed to position compound 3v into the E. coli FabH active site to determine the probable binding conformation.
设计并合成了一系列新型席夫碱衍生物，并评估了它们作为 FabH 潜在抑制剂的生物活性。这些化合物的抗菌活性被测定，以评估其对大肠杆菌、铜绿假单胞菌、枯草芽孢杆菌和金黄色葡萄球菌的抑制作用。具有强烈抗菌活性的化合物被测试其对大肠杆菌 FabH 的抑制活性。化合物 3v 对测试的细菌菌株显示出最有效的抗菌活性，MIC 为 1.56-6.25μg/mL，并表现出最强的大肠杆菌 FabH 抑制活性，IC(50)为 4.3μM。通过对接模拟将化合物 3v 定位到大肠杆菌 FabH 的活性部位，以确定可能的结合构象。
