How to use
In Vitro:
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.
In Vivo:
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.
