In Vitro 2-Hydroxyestrone exhibits antiestrogen action on MCF-7 human breast cancer cells. Addition of 2-Hydroxyestrone to the cell cultures in concentration of 1-1000 nM has no effect on cell growth and proliferation because of rapid O-methylation of the catechol estrogen by catechol O-methyltransferase which is highly active in these cells. In the presence of quinalizarin, a potent catechol O-methyltransferase inhibitor which reduces the O-methylation of the steroid, 10 and 100 nM 2-Hydroxyestrone markedly suppresses the growth and proliferation of the cells[2]. Cell Proliferation Assay[2] Cell Line: Human breast cancer cell lines MCF-7, MDA-MB-231, and MDA-MB-330 Concentration: 1-1000 nM Incubation Time: 6 days Result: 10 and 100 nM markedly suppressed the growth and proliferation of the cells in the presence of quinalizarin. The tumor cell growth-inhibitory action of the catechol estrogen was neutralized by the presence of 1 nM estradiol.
In Vivo Levels of both 2-Hydroxyestrone (2-OHE1; 2 mg/kg; administered ip.) and  2-Hydroxyestrone 4-N-acetylcysteine thioether (2-OHE1 4SR) in rats treated with 2-Hydroxyestrone were significantly different between the induced and noninduced groups[3]. Animal Model: Female and male Sprague-Dawley rats (6 weeks old)[3] Dosage: 2 mg/kg Administration: Administered i.p. Result: Levels of both 2-OHE1 and  2-OHE1 4SR in rats treated with 2-OHE1 were significantly different between the induced and noninduced groups.
