Methoxychlor, o,p'-DDT1, pentachlorophenol, and nonylphenol significantly reduced [3H] 17 beta-estradiol binding to the estrogen receptor by 10, 60, 20, and 75%, respectively.

In this study, the ability of 2-tert-butylphenol, 2-isopropylphenol, 4-tert-octylphenol (4-t-OP), 2,4-dichlorophenol (2,4-DCP), 3,4-dichlorophenol (3,4-DCP), pentachlorophenol (PCP), bisphenols A (BPA), tetrabromobisphenol A (TBBPA), tetrachlorobisphenol A (TCBPA) and 4-phenylphenol to activate estrogen receptor (ER), androgen receptor (AR), progesterone receptor (PR) and estrogen-related receptor (ERR) were determined using a set of recombined yeast strains.

Antagonistic activities toward hERalpha and hERbeta were shown in three (carbaryl, pentachlorophenol and 2,4,5-trichlorophenoxyacetic acid) and seven (chlordecone, methoxychlor, carbaryl, endosulfan, endrin, dieldrin, aldrin) pesticides, respectively.

15081572 Jung J, Ishida K, Nishihara T: Anti-estrogenic activity of fifty chemicals evaluated by in vitro assays. Life Sci. 2004 May 7;74(25):3065-74.

We examined the anti-estrogenic activity of 50 chemicals by the yeast two-hybrid assay and detected the activity of hexachlorophene, pentachlorophenol, and vitamin K3 (menadione), in that order.
These chemicals were also observed to inhibit the transcriptional activity of 17beta-estradiol in a reporter gene assay system using MCF-7 cells, estrogen receptor-positive breast cancer cells, and to bind directly to estrogen receptor alpha in a competitive binding assay system, although the order of the activity was slightly different among the 3 assays.

Moreover, pentachlorophenol acts as an antagonist of the induction by estradiol of rainbow trout ER and Vg gene expression.

Toxicol Lett. 2006 May 25;163(2):130-41. Epub 2005 Nov 8.

We examined expression profiles of estrogen-responsive genes after treatment with alkylphenols (p-cresol (pC), 4-n-ethylphenol (4EP), 4-n-heptylphenol (4HP), 4-t-octylphenol (4OP) and nonylphenol (NP)), chlorinated phenols (4-chlorophenol (4CP), 4-chloro-3,5-dimethylphenol (CDP), 2,4-dichlorophenol (DCP) and pentachlorophenol (PCP)), parabens (methylparaben (MPB), ethylparaben (EPB) propylparaben (PPB) and butylparaben (BuPB)), or bis- and benzoylphenols (bisphenols A and B and p-hydroxybenzophenone (pHBP)) by means of a DNA microarray assay first to evaluate the estrogenic activity of these chemicals and then to understand the structural basis for the activity.
By selecting a set of 120 genes showing greater statistical reliability for estrogen, a more reliable assay for each of the chemicals was achieved and, for the chemicals for which data were available, the results were consistent with those of previously reported estrogen receptor-binding and yeast two-hybrid assays except for chlorinated and few other phenols.

This work evaluated the joint anti-estrogenic effects of pentachlorophenol (PCP) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) against 17beta-estradiol (E2) in juvenile goldfish (Carassius auratus) hepatocyte cultures.
The anti-estrogenic effects of PCP appeared to result primarily from the competitive binding to estrogen receptor.

Numerous synthetic chemicals have estrogenic activity by interacting with the estrogen receptor.
However, the estrogenic chemicals p-nonylphenol and 4-tert-octyphenol, and pentachlorophenol, effectively inhibited the activity of the hPR in yeast.

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.
