We report the initial results of our study into a series of simple 4-sulfam
ated phenyl alkyl ketones as potential inhibitors of the enzyme estrone sul
fatase. The results of the study show that these compounds are potent inhib
itors, possessing greater inhibitory activity than COUMATE, but weaker acti
vity than EMATE. Furthermore, the compounds are observed to be irreversible
inhibitors. (C) 2001 Elsevier Science Ltd. All rights reserved.
