摘 要:為了尋求廣譜、高效、安全的魚(yú)尼丁受體作用劑,設計并合成了9個(gè)鄰氨基N-甲氧基苯甲酰胺類(lèi)化合物。其結構經(jīng)1H NMR、HPLC-Mass和IR分析確證。初步生物活性測試表明:目標化合物在100 mg/L濃度下對鱗翅目粘蟲(chóng)(Mythimna separata)有100%的致死率。在500 mg/L濃度下,大多化合物對同翅目的豆蚜(Aphis fabae)以及葉蟬(Nephotettix cincticeps)具有顯著(zhù)的活性,如化合物11a、11c、11e和11g對蚜蟲(chóng)的活性在90%以上,化合物11e和11i對葉蟬的活性達到了100%。在500 mg/L濃度下,目標化合物對螨蟲(chóng)紅蜘蛛(Tetranchus urticae)沒(méi)有表現出明顯活性。 |

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. |
Key words:N-methoxyl-o-aminobenzamide;ryanodine receptor;insecticide |
