摘要
用多元线性回归分析对50个在Pirkle型手性固定相色谱柱上手性拆分的乙内酰脲类化合物进行了QSRR(quantitativestructure-rententionrelationship)和QSERR(quantitative-structureenantioselectiverententionrelation-ship)研究.所选的2D和3D描述参数由分子力学和量子化学计算得到.回归结果表明,R和S异构体与识别剂的相互作用的确存在差异.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,还可以定量的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.
Quantitative structure-retention relationships (QSRR, retention factors k(1) and k(2) for the first and second eluted enantiomer) as well as quantitative enantioselective retention relationships (QSERR, separation factor alpha) for a series of 50 chiral 5-arylhydantoins on the Pirkle-type chiral stationary phases are derived by the multiple linear regression analyses calculations using 2D and 3D molecular descriptors including those obtained by quantum chemical calculations. Different interactions between the different configuration and the CSP (chiral state phase) have been detected. The models will be useful to speculate the combining mode between the CSP and the analogues as well as to quantitatively prognosticate the separation of other 5-arylhydanoin analogues on Pirkle type chiral stationary phases.
