| 摘 要： | 基于定量结构-活性关系(QSAR)研究取代苯酚化合物的性质具有重要意义.分子电性距离矢量(MEDV)是1种描述分子二维结构的拓扑描述子,由4种类型原子间的相互作用得到的10个矢量组成.采用MEDV表征取代苯酚化合物的分子结构,运用多元线性回归技术,同时采用逐步回归结合统计检测对模型变量进行筛选,建立了取代苯酚诱发浮萍萎黄活性、取代苯酚臭氧氧化表观速率常数与MEDV的QSAR模型,继用留一法和外部样本检验模型稳定性能.其复相关系数(R)、留一法(LOO)交互校验复相关系数(Rcv)和外部样本校验复相关系数(Qext)分别为0.9850、0.9621、0.8218;0.8579、0.7621、0.7966.结果表明,MEDV计算简单,对于取代苯酚的结构表征能力较强,所建OSAR模型具有良好的稳定性和预测能力.
