摘    要:用比较分子力场分析(CoMFA)方法对50个自主设计并合成的新型芳基烷基肟醚化合物杀粘虫活性的定量构效关系进行了研究。所得模型交叉验证参数q^2为0.598,非交叉验证相关系数r^2为0.949,标准偏差SE=0.136,F=92.419,影响药效的立体场与静电场的贡献分别50.6%和49.4%。CoMFA等值线图表明化合物肟苯环对位取代基是影响其杀粘虫活性的主要因素,体积和电性增加有利于提高化合物的杀粘虫活性。该模型三维等值线图为该类化合物的结构改造提供了理论依据。

关 键 词:新型肟醚化合物  杀粘虫活性  三维定量构效关系(3D—QSAR)  比较分子力场分析(CoMFA)

Abstract:The quantitative relationship between the structure of novel Oxime-ether pyrethroids and their insecticidal activity against Mythimna separate was studied by comparative molecular field analysis( CoMFA). The coefficient q2of cross validation and the relation coefficient r2 of non-cross validation for the model established is 0. 598 and 0. 949 .respectively, its F value is 92. 419 and the standard deviation is 0. 136. The contributions of steric and electrostatic fields to the activity are 50. 6% and 49. 4% respectively. The contour maps of the model indicate that p-substituent on phenyl ring of oxime moiety of the compound is the main factor affecting the activity. The larger volume and stronger electricityp-substituent has, the higher activity the compound will has. the model will give the basis on the structure modification.
Keywords:novel Oxime-ether pyrethroids  mythimna separate  3D-QSAR  CoMFA
