Catechol estrogen | Wikipedia audio article

2-Methoxyestrone (2-ME1) is an endogenous, naturally occurring methoxylated catechol estrogen and metabolite of estrone that is formed by catechol O-methyltransferase via the intermediate 2-hydroxyestrone. Unlike estrone but similarly to 2-hydroxyestrone and 2-methoxyestradiol, 2-methoxyestrone has very low affinity for the estrogen receptor and lacks significant estrogenic activity.
