Estradiol sulfamate

Estradiol sulfamate (E2MATE; developmental code names J995, PGL-2, PGL-2001, ZK-190628, others), or estradiol-3-O-sulfamate, is a steroid sulfatase (STS) inhibitor which is under development for the treatment of endometriosis. It is the C3 sulfamate ester of estradiol, and was originally thought to be a prodrug of estradiol.
