应用分子电性距离矢量(MEDV)对吡喃酮类化合物进行结构表征和抗人类免疫缺 陷病毒(human immuno-deficiencyvirus,简称HIV)的活性预测,通过逐步回归 (SMR)方法建立了MEDV与活性之间的定量模型,取得了良好的结果,其模型相关系 数R=0.958;继以留一法(Leave-one-out,LOO)进行交互检验,相关系数R=0. 835,说明定量相关模型具有良好的稳定性和预测能力.

The molecular electrongativity-distance vector (MEDV) was used to describe the chemical structure of 18 pyrones and correlated with their anti-HIV activities. A reasonable molecular modeling equation was achieved with a quite high correlation coefficient (R= 0.958) by a stepwise multiple regression (SMR) for the prediction of the anti-HIV activity. The performance of the model was tested through cross- validation by the leave-one-out procedure (LOO) and satisfactory results were obtained ( R = 0.853), which shows that the estimation stability and prediction of the model based on the MEDV descriptors.
