virtual screening based on the 3D structure of the subunit H of V-ATPase in previous study. 74 benzenesulfonyl derivatives were synthesized and their insecticidal activities were evaluated. The derivatives with propargyl substituents exhibit excellent insecticidal activities against Mythimna separata Walker. The LD50 values of compounds A5.7 (28.0 μg·g−1) and B5.7 (36.4 μg·g−1) were significantly less than
Abstract A series of 4-(propargyloxy) benzenesulfonamide derivatives with different substituents on the benzene ring were synthesized and evaluated for their insecticidalactivity. Some of the compounds showed good insecticidalactivity against Mythimna separata, and the LC50 value of the most active compound B2.5 was 0.235 mg/ml. Ultrastructural changes in the midgut epithelial cells of Mythimna separata
Abstract Sixty-nine 4-propargyloxybenzene sulfonamide derivatives with different aminoacids as amino substituent were synthesized and evaluated for their insecticidal activity against third-instar Mythimna separate. The bioassay results revealed that some derivatives bearing aminoacid ester group performed good insecticidal activity against third-instar M.separata, such as the LC50 values of D18
