从三维角度出发,采取不同的构象搜索方法得到了咪唑酮类化合物分子的活性构象。利用比较分子场分析方法进一步证实了模板分子构象的正确性。并从静电场、立体场及活性关系等方面进行了三维定量构效关系研究,得到了具有较强预测能力的QSAR模型。

关键词: 咪唑酮P, 除草剂, 构效关系

An active conformer of the imidazolinone compounds has been obtained by adopting different conformational search methods. The model molecule has been confirmed using the Comparative Molecular Field Analysis (CoMFA). A 3D-QSAR study on a series of 5-substituted imidazolinone compounds exploring the relationship between the electrostatic, stereo interaction with ALS inhibitory activity has been finished. A QSAR model of high predicting ability has been obtained.

Key words: IMIDAZOLONE P, HERBICIDES, STRUCTURE ACTIVITY RELATIONSHIP
