A Potent and Highly Selective Sulfotransferase Inhibitor

Abstract
In the present work, we have used a newly developed, fluorescence-based assay to screen a library of >30 000 compounds as potential β-arylsulfotransferase-IV inhibitors. A total of 11 inhibitors were discovered. Most of the compounds discovered showed low micromolar inhibition, but one of the compounds showed potent inhibition (Ki = 96 nM). The most potent of these inhibitors was tested against a variety of other purine binding enzymes and showed remarkable specificity.
