Background

2-hydroxy Estrone is an active metabolite of the endogenous estrogen estrone .¹ It is formed from estrone primarily by the cytochrome P450 (CYP) isoforms CYP1A2, CYP1A1, and CYP1B1 and metabolized to 2-methoxy estrone by catechol-O-methyltransferase (COMT). 2-hydroxy Estrone (10 µM) inhibits the proliferation of estrogen receptor-positive MCF-7, but not estrogen receptor-negative MDA-MB-231, breast cancer cells cultured with the COMT inhibitor quinalizarin.² It inhibits iron-ADP-adriamycin complex-induced lipid peroxidation of liposomes prepared from rat liver microsomes (IC₅₀ = 2.7 µM).³
