Abstract

Gonadotropin-releasing hormone (GnRH) receptor antagonists are an important class of compounds designed to block the pituitary gland from synthesizing follicle-stimulating hormone and luteinizing hormone for the treatment of sex hormone dependent disorders. Elagolix (ABT-620) is currently approved for the treatment of pain associated with endometriosis and as a combination with estradiol and norethindrone acetate is approved for management of heavy menstrual bleeding due to uterine fibroids. In order to support the development of elagolix, we prepared [3 H]elagolix for preclinical metabolism studies and [14 C]elagolix for environmental risk assessment studies.
