Abstract

A new method for assessment of molecular similarity based on original description of chemical structure is discussed. The accuracy of similarity assessment obtained with this method is compared with that of the results of four other approaches. The same evaluation set is used to predict: (a) boiling point of 139 hydrocarbons and (b) mutagenicity of 15 nitrosamines. The results show that the proposed method provides reasonable appraisal for both properties, but prediction of mutagenicity is more accurate in this method as compared to the alternatives.
