摘 要:为了寻求广谱、高效、安全的鱼尼丁受体作用剂,设计并合成了9个邻氨基N-甲氧基苯甲酰胺类化合物。其结构经1H NMR、HPLC-Mass和IR分析确证。初步生物活性测试表明:目标化合物在100 mg/L浓度下对鳞翅目粘虫(Mythimna separata)有100%的致死率。在500 mg/L浓度下,大多化合物对同翅目的豆蚜(Aphis fabae)以及叶蝉(Nephotettix cincticeps)具有显著的活性,如化合物11a、11c、11e和11g对蚜虫的活性在90%以上,化合物11e和11i对叶蝉的活性达到了100%。在500 mg/L浓度下,目标化合物对螨虫红蜘蛛(Tetranchus urticae)没有表现出明显活性。

Abstract:To seek for broad spectra,high efficiency and safe pesticides which work on ryanodines receptor,nine novel N-methoxyl-o-aminobenzamide derivatives were designed and synthesized. Their structures were confirmed by 1H NMR. The preliminary bioactivity evaluation showed that the compounds had 100% insecticidal activities against lepidopte ranpests Mythimna separata at 100 mg/L. At 500 mg/L,most of the compounds exhibited good activities against Homopteran pests Aphis fabae and mite Nephotettix cincticeps. For example,compounds 11a,11c,11e and 11g showed more than 90% insecticidal activities against Aphis fabae;the compound 11e and 11i showed 100% insecticidal activities against Nephotettix cincticeps. All of the title compounds exhibited no acaricidal activities against mite at 500 mg/L.
