目的合成并筛选出杀虫活性较好的新型抗肝片吸虫病化合物。方法分别以邻(间、对)氯苯酚为原料，通过磺酰化和亲核取代反应合成了14种羟基苯二磺酰苯胺类化合物;通过元素分析、红外光谱及核磁共振氢谱对合成的14种新型抗肝片吸虫病化合物羟基苯二磺酰苯胺类化合物(1～14)的结构进行了表征,并测定其对线粒体呼吸控制率的影响以及线粒体呼吸过程无机磷的变化,以此对化合物的解偶联活性(杀虫活性)进行了评价。结果所合成的大部分羟基苯二磺酰苯胺类化合物均具有较好的解偶联活性,其中3,5,6,9的杀虫活性最好。结论 化合物3,5,6,9均有望成为较好的新型抗肝片吸虫病药物。

SYNTHESIS AND INSECTICIDAL ACTIVITY OF THE NOVEL HYDROXYLBENZENEDISULFONANILIDES COMPOUNDS

AIM: To synthesize novel derivatives of hydroxylbenzenedisulfonanilide with high insecticidal activity against the Fasciola hepatica. METHODS: o-(m-, p-) Chlorphenol were used to synthesize the title compounds by sulphonation and nucleiphilic-substitution reaction. The uncoupling activity (insecticidal activity) of these compounds were tested by determining the influence on mitochondrial respiration control ratio (RCR) and the variation of inorganic phosphate in oxidative phosphorylation (delta Pi). RESULTS: Compounds 1-14 are new compounds. The structures of the compounds were determined by IR, HNMR and elemental analysis. Most new compounds have relatively high uncoupling activities, especially compounds 3, 5, 6 and 9. CONCLUSION: Compounds 3, 5, 6 and 9 will become novel fasciolicides and are worth further studying.
