New drug-like hydroxyphenylnaphthol steroidomimetics as potent and selective 17β-hydroxysteroid dehydrogenase type 1 inhibitors for the treatment of estrogen-dependent diseases

Inhibition of 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) is a novel and attractive approach to reduce the local levels of the active estrogen 17β-estradiol in patients with estrogen-dependent diseases like breast cancer or endometriosis. With the aim of optimizing the biological profile of 17β-HSD1 inhibitors from the hydroxyphenylnaphthol class, structural optimizations were performed at the 1-position of the naphthalene by introduction of different heteroaromatic rings as well as substituted phenyl groups. In the latter class of compounds, which were synthesized applying Suzuki-cross coupling, the 3-methanesulfonamide 15 turned out to be a highly potent 17β-HSD1 inhibitor (IC50 = 15 nM in a cell-free assay). It was also very active in the cellular assay (T47D cells, IC50 = 71 nM) and selective toward 17β-HSD2 and the estrogen receptors α and β. It showed a good membrane permeation and metabolic stability and was orally available in the rat.

ERβ ligands. 3. Exploiting two binding orientations of the 2-phenylnaphthalene scaffold to achieve ERβ selectivity

The 2-phenylnaphthalene scaffold was explored as a simplified version of genistein in order to identify ER selective ligands. With the aid of docking studies, positions 1, 4, and 8 of the 2-phenylnaphthalene template were predicted to be the most potentially influential positions to enhance ER selectivity using two different binding orientations. Both orientations have the phenol moiety mimicking the A-ring of genistein. Several compounds predicted to adopt orientations similar to that of genistein when bound to ERβ were observed to have slightly higher ER affinity and selectivity than genistein. The second orientation we exploited, which was different from that of genistein when bound to ERβ, resulted in the discovery of several compounds that had superior ER selectivity and affinity versus genistein. X-ray structures of two ER selective compounds (i.e., 15 and 47) confirmed the alternate binding mode and suggested that substituents at positions 1 and 8 were responsible for inducing selectivity. One compound (i.e., 47, WAY-202196) was further examined and found to be effective in two models of inflammation, suggesting that targeting ER may be therapeutically useful in treating certain chronic inflammatory diseases.
