A series of estrogen receptor ligands based on a 3-alkyl naphthalene scaffold was synthesized using an intramolecular enolate-alkyne cycloaromatization as the key step.

J Med Chem. 2008 Apr 10;51(7):2158-69. Epub 2008 Mar 7.

This reaction takes place in the target cell where the estrogenic effect is exerted via the estrogen receptor (ER).

The induction of beta-galactosidase activity was strictly dependent on the presence of seabream (Sparus aurata) betaa estrogen receptor (sbERbetaa) and substances known to have estrogenic activity. 17beta-Estradiol (E (2)) and diethylstilbestrol (DES), both agonists, were most active and the antagonist tamoxifen (TAM) was 14-fold less active than E (2).
Among the chemicals tested bisphenol-A was most active, followed by pentachlorophenol and naphthalene.

The performance of the spectroscopic EVA (eigenvalue) and EEVA (electronic eigenvalue) methods was tested with data sets applying coumarin 7-hydroxylation inhibitors (28 compounds) for cytochrome P450 mouse CYP2A5 and human CYP2A6 enzymes and 11ss-, 16a-, and 17a-substituted estradiol derivatives (30 compounds) for the lamb uterine estrogen receptor, and compared with the performance of the classical Hansch-type, CoMFA and GRID/GOLPE methods.

Mol Cell Endocrinol. 2009 Mar 25;301(1-2):205-11. Epub 2008 Oct 4.

After identification of the 6-(3'-hydroxyphenyl)-2-naphthol scaffold 1, the potency of this class of inhibitors was further improved by substitution of the 1-position of the naphthalene ring by a phenyl group (compound 18, IC (50)=20nM).
Compound 18 also showed a good selectivity toward 17beta-HSD2 and the estrogen receptors alpha and beta.
