4,4'-Benzophenone-O,O'-disulfamate: a potent inhibitor of steroid sulfatase.
We investigated whether the benzophenone moiety can be used as core element of steroid sulfatase (STS) inhibitors. While 4- and 3-benzophenone-O-sulfamates inhibit STS with IC(50) values between 5 and 7 microM irrespective of additional hydroxy and methoxy substituents at the second phenyl ring, benzophenone-O,O'-disulfamates show increased activity. With an IC(50) value of 190 nM the 4,4'-derivative is the first small monocyclic STS inhibitor coming close to the potency of the steroidal standard estrone sulfamate.
