pyrimidine heteroaryl groups for the characteristic phenol ring of non-steroidal estrogens. The unexpectedly low affinity showed by some of these compounds is ascribed, in part, to a resonance-enforced conformational constraint that prevents their optimal accommodation in the ER ligand binding pocket.
