Estradiol 3-sulfamate (BLE 00084; E2MATE; ES-J 995) is a potent, long-acting, and orally active steroid sulfatase inhibitor; inhibits estrone sulfatase with an IC50 of 251 nM and a Ki of 133 nM.
Introduction of a fluoro, chloro, or bromo moiety at the C-2 position of EMATE and Estradiol 3-sulfamate and that of a fluoro moiety at the C-4 position of the parent sulfamates markedly increase the estrone sulfatase inhibitory activity[1].
Estradiol 3-sulfamate is readily transformed and absorbed in the gut into its oxidative metabolite, EMATE, and both compounds have already been shown to be potent, long-acting, and orally active STS inhibitors[2].
