A series of 17 alpha-derivatives of 17 beta-estradiol was synthesized and tested for their ability to inhibit the estrone-sulfatase activity transforming estrone sulfate to estrone. A strong inhibitory activity was obtained when an alkyl side chain or a substituted benzyl was introduced at position 17 alpha of estradiol. The 17 alpha-(3'-bromobenzyl)-estradiol (26) and 17 alpha-(4'-t-butylbenzyl)-estradiol (30) were the most potent estrone-sulfatase inhibitors obtained in our study with IC50 values of 24 and 28 nM, respectively. They also represent a new family of estrone-sulfatase inhibitors. These compounds are about 300-fold more effective in interacting with the enzyme than the substrate estrone sulfate itself.

inhibit steroidsulfataseactivity may be a rewarding approach to the treatment of androgeno-sensitive and estrogeno-sensitive diseases. In the present study, we report the chemical synthesis and biological evaluation of a new family of steroidsulfatase inhibitors. The inhibitors were designed by adding an alkyl, a phenyl, a benzyl, or a benzyl substituted at position 17alpha of estradiol (E(2)), a C18-steroid
