| Resumen |
A number of hydrazines were selected to examine the use of quantitative structure-activity relationship (QSAR) in the prediction of biological behaviour. The mutagenic activity of the selected hydrazines was tested using the same method of assay and test results were evaluated statistically. All the hydrazines tested were found to be mutagenic, with potencies varying over 2-3 orders of magnitude. Modelling procedures were used to determine which descriptors should be used to establish the QSAR. Results showed that it is possible to predict the mutagenic potential of a series of N,N-disubstituted hydrazine derivatives from their physicochemical properties by the use of a systematic test series design. |
