The bioisosteric replacement of the phenol ring, a signature functional group of most estrogen receptor (ER) ligands, with a hydrogen-bonded pseudocyclic ring, led to the development of a novel class of nonsteroidal ER-ligands based on a salicylaldoxime template. A series of structural modifications were applied to selected molecules belonging to the monoaryl-salicylaldoxime chemical class in an attempt to improve further their ER beta-selective receptor affinity and agonist properties. Among several modifications, the best results were obtained by the simultaneous introduction of a meta-fluorine atom into the para-hydroxyphenyl substituent present in the 4-position of salicylaldoxime, together with the insertion of a chloro group in the 3-position of the central scaffold. The resulting compound showed the best affinity (K-i = 7.1 nM) and selectivity for ER beta over ER alpha. Moreover, in transcription assays, it proved to be a selective and potent ER beta-full agonist with an EC50 of 4.8 nM.

Some of these compounds are efficient inhibitors of glucose uptake in lungcancercells and have a notable antiproliferative effect. In contrast to their 5‐aryl‐substituted regioisomers, the newly synthesized compounds reported herein do not display significant binding to the estrogen receptors. The inhibition of glucose uptake in cancercells by these compounds was further observed by fluorescence
