Oestrone 3-O-(N-acetyl)sulphamate, a potential molecular probe of the active site of oestrone sulphatase

N,N-Dialkylated derivatives of the steroid sulphatase inhibitor, oestrone 3-O-sulphamate (EMATE) are weak reversible inhibitors of the enzyme. N-Acetylated-EMATE (8), but not the benzoyl derivative, inhibits the enzyme irreversibly, albeit less potently than EMATE and will allow hitherto difficult radiolabelling on the sulphamate group to facilitate investigation of the enzyme inactivation mechanism.
