title: The design, synthesis, and in vitro biochemical evaluation of a series of esters of 4-[(aminosulfonyl)oxy]benzoate as novel and highly potent inhibitors of estrone sulfatase.
abstract: We report the initial results of our study into the use of a potential transition-state (TS) of the reaction catalysed by the enzyme estrone sulfatase (ES) in the design of a series of cyclic esters of 4-[(aminosulfonyl)oxy]benzoate as novel inhibitors of ES. The results of the study show that these compounds are some of the most potent inhibitors known todate, possessing greater inhibitory activity than the three standard compounds: 4-methylcoumarin-7-O-sulfamate (COUMATE); the tricyclic derivative of COUMATE, namely 667-COUMATE (which is in Phase I of clinical trials) and; the steroidal inhibitor estrone-3-O-sulfamate (EMATE).
