摘要: 重点考察了反映分子整体性质的表面积及构象差异等结构因素对活性的影响,以活性PI50值落于7.5751~3.0752之间的23个新合成的磺酰脲分子为研究对象,运用多元回归方法进行了研究,结果表明:反映分子表面积大小的AREA值及反映分子构象差异的d1、d2、d值明显地影响了此类磺酰脲农药分子的活性。

关键词: 磺酰脲分子, 构象差异, 表面积, 构效关系

Abstract: In order to study the factors further which affect the SARof sulfonylurea molecules,we inspect mainly the characteristic structure factors of the whole molecule such as surface area and conformation difference.The research objects are 23 newly synthesized sulfonylurea molecules whose PI50 values are from 7.5751 to 3.0752.We apply multiply regression in this paper.The result shows that the AREA value,which reflects the surface area,and the d1,d2 and d values,which reflect the conformation difference,influence remarkably the activity of this series of sulfonylurea molecules.

Key words: Sulfonylurea molecule, Conformation difference, Surface Area, SAR
