Quantitative Structure‐Activity Relationship (QSAR) Studies Using Electronic Descriptors Calculated from Topological and Molecular Orbital (MO) Methods

The performance of certain electronic descriptors rapidly calculated by a topology-based method has been compared with those computed by time-consuming MO methods for QSAR studies on mutagenicity of a set of triazenes. The highly significant correlations obtained in the two cases not only are of excellently comparable statistical quality but also support the same mechanism of mutagenicity.
