Catechol estrogen adducts.
Reaction of estrone-3,4-o-quinone with ethanethiol and glutathione leads to the formation of 4-hydroxyestrone-2-thioethers. Incubations of [1-3H]hydroxyestrone with rat liver microsomes and NADPH in the presence of glutathione results in the formation of 4-hydroxyestrone-S-glutathione with no release of tritium in the water indicating GSH addition to C-2 of 4-hydroxyestrone.
