QSAR for Binding Affinity of Substituted Dibenzoylhydrazines to Intact Sf-9 Cells
QSAR dibenzoylhydrazines Sf-9 cells Spodoptera frugiperda
font style='font-size:12px;'>
2009/3/5
The binding affinity to intact Sf-9 cells was measured in a series of N-t-butyl-N,N′-dibenzoylhydrazine congeners. The benzene ring close to the t-butyl group of the compounds was substituted with C...
QSAR of 2,4-diphenyl-1,3-oxazolines for ovicidal activity against the two-spotted spider mite Tetranychus urticae
2,4-diphenyl-1,3-oxazoline QSAR two-spotted spider mites Tetranychus urticae
font style='font-size:12px;'>
2009/3/5
Ovicidal activity of 2,4-diphenyl-1,3-oxazoline congeners with various substituents on the 4-phenyl ring against two-spotted spider mites Tetranychus urticae was quantitatively analyzed using the cl...
摘要 用CoMFA方法对一组含氟农药分子的抗小麦赤霉病活性进行了定量构效关系研究。发现影响药效的立体场与静电场的贡献分别为90.3%和9.7%，立体场的影响是占主导性的。该模型非交叉验证的相关系数(r^2)为0.991，F值是297.524，标准偏差(S)为0.015，表明模型具有较好的预测能力。根据该模型，设计并预测了几个新的化合物，其活性都在0.96以上。经过研究表明在预测结构的某些位置添加位...
