Applications of the Periphery of Projection in Studies of the Quantitative Structure-activity Relationship of Nitrobenzenes

In this paper, the periphery of projection of a molecule is described based on three-dimensional projection, and the new invariable was used for quantitative structure-activity relationship studies. Much better results were obtained, if Am indexes, indicated index and quantum-chemical parameters were combined with the new index. If on the new parameter, periphery of projection of a molecule, the correlation coefficient is 0.939; whereas the correlation coefficient is 0.954 because the addition of the new index. Artificial neural networks were performed to predict the toxicity of nitrobenzenes, and the satisfactory result, the correlation coefficient of 0.986, were achieved.
