摘要
用三维原子场全息作用矢量(3D-HoVAIF)对27个三联苯类环氧合酶抑制剂药物进行了定量结构活性关系考察。用多元线性回归建模,该模型的复相关系数(R2cum)、留一法交互校验复相关系数(Q2CV)和模型的标准偏差(SD)分别为0.939、0.821和0.137。结果表明,3D-HoVAIF在分子结构表征和生物活性预测上有较好的适用性。
A newly developed three-dimensional holographic vector of atomic interaction field (3D- HoVAIF) is used to describe the chemical structures of terphenyl cyclooxygenase-2 (COX-2) inhibitors. A model of quantitative relationship between structure and activity(QSAR) is built by using multiple linear regression (MLR). The correlation coefficient (R2cum ) of the established model, leave- one-out (LOO) cross-validation (CV) correlation coefficient ( QZcv ), standard deviation (SD) of the model are 0. 939, 0. 821 and 0. 137 respectively. These results showed that 3D-HoVAIF could satisfactorily express the information related to biological activity of terphenyls.
