To develop new antibacterial agents, a series of novel triazole-containing pyrazole ester derivatives were designed and synthesized and their biological activities were evaluated as potential topoisomerase II inhibitors. Compound 4d exhibited the most potent antibacterial activity with Minimum inhibitory concentration (MIC) alues of 4 µg/mL, 2 µg/mL, 4 µg/mL, and 0.5 µg/mL against Staphylococcus aureus
为了开发新的抗菌剂,设计并合成了一系列新型含三唑的吡唑酯衍生物,并评估了它们作为潜在拓扑异构酶 II 抑制剂的生物活性。化合物 4d 表现出最有效的抗菌活性,对金黄色葡萄球菌、单核细胞增生李斯特菌、大肠杆菌和鸡沙门氏菌的最小抑菌浓度 (MIC) 为 4 µg/mL、2 µg/mL、4 µg/mL 和 0.5 µg/mL , 分别。体内酶抑制试验 4d 显示出最有效的拓扑异构酶 II (IC50 = 13.5 µg/mL) 和拓扑异构酶 IV (IC50 = 24.2 µg/mL) 抑制活性。进行分子对接以将化合物 4d 定位到拓扑异构酶 II 活性位点以确定可能的结合构象。总之,
