Ethinylestradiol sulfamate

Chemical compound From Wikipedia, the free encyclopedia

Ethinylestradiol sulfamate (developmental code name J1028), or 17α-ethynylestradiol 3-O-sulfamate, is a synthetic estrogen and estrogen ester which was never marketed.[1][2][3] It is the C3 sulfamate ester of ethinylestradiol.[1] The drug shows considerably improved oral estrogenic potency (uterotrophic) relative to ethinylestradiol in rats but without an increase in hepatic estrogenic potency.[1][3] Related compounds like ethinylestradiol N,N-diethylsulfamate (J271) and ethinylestradiol pyrrolidinosulfonate (J272) have also been developed, and have similar properties in animals.[4] However, the closely related compound estradiol sulfamate (E2MATE) failed to show estrogenic activity in humans, which is because it is additionally a highly potent inhibitor of steroid sulfatase and prevents its own bioactivation into estradiol.[5]
