derivatives were evaluated against the maize armyworm, Spodoptera frugiperda (J.E. Smith). These hybrids were prepared through a copper-catalyzed azide alkyne cycloaddition (CuAAC, known as a click reaction) and displayed larvicidal properties with LD50 values below 3 mg/g insect, and triazolyl-quinoline hybrid 6 showed an LD50 of 0.65 mg/g insect, making it 2-fold less potent than methomyl, which was
评价了五种7-氯-4-(1 H -1,2,3-三唑-1-基)喹啉衍生物对玉米粘虫Spodoptera frugiperda(JE Smith)的杀虫和拒食活性。这些杂化物是通过铜催化的叠氮化物炔烃环加成反应(CuAAC,称为点击反应)制备而成的,具有幼虫特性,LD 50值低于3 mg / g昆虫,三唑基喹啉杂化物6的LD 50为0.65 mg / g。克杀虫剂,使其效力比用作参照杀虫剂的灭多威低2倍(LD 50 = 0.34 mg / g杀虫剂)。化合物4是活性最高的拒食衍生物(CE 50= 162.1μg/ mL),在250–1000μg/ mL的浓度下具有良好的拒食指数(56–79%)。另外,三唑基-喹啉杂化4 - 8表现出对商业乙酰胆碱酯酶弱的抑制活性,从电盘electricus(电鳗的AChE)(IC 50 = 27.7微克/毫升),以及对低的抗胆碱酯酶活性草地夜蛾幼虫匀浆(IC 50
