用比较分子场分析法(CoMFA)研究了5-芳基乙内酰脲类化合物定量结构-保留关 系。本研究林构象搜索所得的低能结构出发构建化合物分子的构象,并进行了全空 间搜索。得到了较好的模型CoMFA的交叉验证回归系数q~2为0.764,模型的线性回 归系数r~2为0.962)。这些方程不仅有助于推测被识别剂和识别剂之间的结合方式 ,还可以定量地预测结构相近的类似物的拆分可能性,为设计合成新的识别剂和被 识别剂都提供了一定的理论依据。

Comparative molecular field analysis (CoMFA) was used to perform a quantitative structure-retention relationship study on resolution of a series of fifty 5-arylhydantoins with the Pirkle type chiral stationary phase column. Satisfactory results were obtained after All Space Searching (ASS), with the leave-one out cross validation correlation coefficient of CoMFA q1 - 0.764 and conventional r2 = 0. 962. The model will be useful to speculate the combining mode between the chiral. stationary phase and the analogues as well as to quantitatively prognosticate the resolution of other 5-arylhydanoin analogues on Pirkle type chiral stationary phases.

Key words: CoMFA, arylhydantoins, QUANTITATIVE STRUCTURE ACTIVITY RELATIONSHIP
