苯甲酰胺类化合物的结构/活性的定量构效关系研究

Studies on Quantitative Structure activity Relationship Between the Structures of Derivatives of Benzamide and Their Antiallergic Activities

用分子连接性指数及比较分子力场分析分别研究了苯甲酰胺类化合物的结构与抗炎活性的关系，结果表明：三维空间上立体效应是描述该类化合物的抗炎活性和进行结构与性能关系研究的最重要的结构参数．

Molecular connectivity index and comparative molecular field analysis (CoMFA)have been applied to the studies of the correlation of the derivatives of benzamide and their antiallergic activities. The results achieved by using CoMFA based on 3D factors are much better than that obtained by using multiple regression analysis based on majorly 2D structural information. The CoMFA results show that the dominant factor which affects activity is steric, whereas electrostatic effect only plays an unimportant role.
