线粒体复合物III是细胞呼吸链的重要组成部分,也是杀菌剂的重要作用靶标之一.根据生物电子等排、活性亚结构拼接原理,设计并合成了一系列含喹啉酮结构三唑磺酰胺衍生物,经质谱、氢谱、碳谱及元素分析对其结构进行了确认,测试了该类化合物对猪心线粒体复合物III的抑制活性,结果表明目标化合物6f[IC50=(45.75±1.02)μmol/L]对复合物III的抑制活性较对照药剂吲唑磺菌胺[IC50=(92.96±1.30)μmol/L]提高了一倍多,可作为先导结构进一步优化.

Complex III is an essential component for cellular respiration chain and one of the most important targets of fungicides. According to bioisosterism and combination of bioactive sub-structive, a series of novel triazolesulfonamide derivatives containing quinolin-2-one moiety were designed and synthesized. The structures of the synthesized compounds were confirmed by MS, 1H NMR, 13C NMR and elemental analysis. The antibacterial activities of these compounds against porcine complex III were evaluated, and the bioassay results indicated that the target compound 6f [IC50=(45.75±1.02) μmol/L] showed much higher inhibitory potency (more than one-fold higher) against complex III than that of the control amisulbrom [IC50=(92.96±1.30) μmol/L], thus compound 6f may recognize as a lead for further structure modification.
