为了寻找具有较好生物活性的吡唑类衍生物,通过活性亚结构拼接的方法,设计制备了一系列未见文献报道的含取代吡啶结构的吡唑肟酯化合物.通过1H NMR、13C NMR和元素分析对目标化合物的结构进行了表征.初步的生物活性测试结果显示,部分化合物表现出一定的杀虫活性.在测试浓度为500 μg/mL时,有7个化合物对粘虫的杀灭活性可达60%~100%,6个化合物对蚜虫的杀死率可达50%~90%.当测试浓度降为100 μg/mL时,1,3-二甲基-5-(4-氯苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5f)和1,3-二甲基-5-(4-甲基苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5j)对蚜虫仍表现出一定的杀虫活性,其杀死率均为50%.1,3-二甲基-5-(3-氟苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5b)和5f在测试浓度为500 μg/mL时对褐飞虱的杀死率均为100%.另外,1,3-二甲基-5-(4-氟苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5c),1,3-二甲基-5-(3-氯苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5e),1,3-二甲基-5-(4-三氟甲氧基苯氧基)吡唑-4-甲醛-O-(2-氯吡啶-3-甲酰基)肟(5i)和5j对人肝癌(HepG2)细胞株显示出明显的抗肿瘤活性,其IC50值分别为2.6,4.6,1.8和1.1 μmol/L.

In order to explore novel pyrazole derivatives with good biological activities, a series of novel pyrazole oxime ester compounds containing pyridyl moiety were designed and synthesized according to the method of active substructure combination. The structures of the target compounds were determined by 1H NMR, 13C NMR and elemental analysis. Preliminary bioassay data indicated that some of the title compounds showed certain insecticidal activities. At a concentration of 500 μg/mL, seven compounds exhibited insecticidal activity against Oriental armyworm with 50%~90%, and six compounds exhibited insecticidal activity against Aphis medicaginis with 50%~90%. When the dosage was lowered to 100 μg/mL, 1,3-dimethyl-5-(4-chlorophenoxy)pyrazole-4-formyl-O-(2-chloropyridin-3-formyl)oxime (5f) and 1,3-dimethyl-5-(4-methylphenoxy)pyra-zole-4-formyl-O-(2-chloropyridin-3-formyl)oxime (5j) were still active against Aphis medicaginis with inhibitory values of 50% and 50%, respectively. Insecticidal activities against Nilaparvata lugens of 1,3-dimethyl-5-(3-fluorophenoxy)pyrazole-4-formyl-O-(2-chloropyridin-3-formyl)oxime (5b) and 5f were both 100% at 500 μg/mL. Additionally, 1,3-dimethyl-5-(4-fluorophenoxy)pyrazole-4-formyl-O-(2-chloropyridin-3-formyl)oxime (5c), 1,3-dimethyl-5-(3-chlorophenoxy)-pyrazole-4-for-myl-O-(2-chloropyridin-3-formyl)oxime (5e), 1,3-dimethyl-5-(4-trifluoromethoxyphenoxy)pyrazole-4-formyl-O-(2-chloro-pyridin-3-formyl)oxime (5i) and 5j displayed good anti-tumor activity against HepG2 cells with IC50 values of 2.6, 4.6, 1.8和1.1 μmol/L, respectively.
