摘 要: 用量子化学密度泛函理论(D FT)以及半经验方法(AM1),对系列β-榄香烯聚乙二醇衍生物分子进行QSAR研究,结果表明,分子的疏水性(logP),极化率,水合能,及分子量是影响化合物抗癌活性的主要因素。 The quantitative structure - activity relationship (QSAR) of a series of β - elemene monosubstituted polyethylene glycol derivatives were studied by using the quantum - chemical density functional theory (DFT) and semi - empirical method ( AM1 ). The result showed that the hydrophobic parameter ( logP), refractivity, hydration energy and mass are the main factors in anti - cancer activity of the compound.
