Abstract

The structural requirements for the binding of steroids to the oestrogen receptor (ER) are important both for the design of new

drugs and to assess the health risks of chemicals with ER affinity. In the present QSAR study of receptor binding affinity (RBA)

for estradiol derivatives, the atom-level electrotopological state indices have been compared with molecular orbital derived,

atom-level parameters for superdelocalisability and atomic charge. The AM1 Hamiltonian was used to calculate molecular

orbital parameters. The predictive power of the QSARs indicated that the superdelocalisability indices provide a better model

than the electrotopological state indices, and that the atomic charges resulted in the highest prediction error. The most accurate

predictions were achieved when other molecular descriptors were also employed in the construction of the QSAR.
