Abstract
This study dealt with the application of CoMFA (comparative molecular field analysis) method in ecotoxicology. CoMFA is based on the analysis of the steric and electrostatic fields of molecules mapped by a probe atom in a molecular mechanics force field. CoMFA was used to model MicrotoxTM EC50 data for 19 chlorophenols. The comparison between the obtained results and those of a classical QSAR regression equation using the n−octanol/water partition coefficient (log P) as molecular descriptor shows that CoMFA can usefully contribute to the study of these compounds.
