【摘要】 目的研究芳香胺致癌活性与结构参数和／或物理化学参数的关系。方法应用中心原子和官能团方法估算芳香胺的物理化学参数，结合多环芳烃结构参数，对两批芳香胺的致癌活性进行Ｆｉｓｈｅｒ判别分析。结果判别效率与汤田浩太郎等建立的系列方程中的两个（Ⅰ、Ⅲ）相近，但不及其最优方程（Ⅱ）。结论所选的物理化学参数适用于大部分芳香胺致癌活性的ＱＳＡＲ研究，Ｆｉｓｈｅｒ判别分析取得较好结果。更多还原

【Abstract】 Objective To study the relationship between carcinogenicity and their structure and phsicochemical parameters of aromatic amines. Methods Fisher discriminant analysis for carcinogenicity of aromatic amines in two different batches was conducted with estimation of parameters of phsicochemical using central atom and functional groups in combination with structural parameters of polycyclic aromatic hydrocarbons(PAHs). Results The discriminant efficacy approximated to that of the two in a series of equations (I and III)established by Yuta,but inferior to the optimal equation II. Conclusion The selected phsicochemical parameters can be applied to QSAR study on carcinogenicity of most aromatic amines,with better results in Fisher discriminant analysis.更多还原
