楝酰胺(Rocaglamide)类化合物的三维定量构效关系
3D-QSAR Study of Rocaglamide Analogues
摘要
Abstract
Rocaglamide analogue with a cyclopentatetrahydrodenzofuran skeleton was shown for the pronounced insecticidal activities. Research on the three dimensional quantitative structure activity relationship (3D-QSAR) of 26 rocaglamide analogues in the training set, was carried with comparative molecular field analysis(CoMFA) and comparative molecular similarity indices analysis (CoMSIA), to build a model for giving references to synthesize analogues with better activities. The cross validated coefficient(q2) was 0. 593 and 0. 656, respectively, in the resulting CoMFA and CoMSIA models, which were used to predict the activities of the training set and 5 analogues in the testing set, showing a favorable predictive ability. Dimensional contour maps of CoMFA and CoMSIA could not only show the visualized interpretation between the important groups in the analogues and activities, but also provide a guidance to improve the structures for prominent biological activities. R1 should be retained with H-donor in the end of the twig; functional R2 and R5 groups with small steric are well for activities. The results show that H-bonding is the most important for insecticidal activities.关键词
