4,4′-Benzophenone-O,O′-disulfamate: a potent inhibitor of steroid sulfatase
摘要:
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 IC50 values between 5 and 7 muM irrespective of additional hydroxy and methoxy substituents at the second phenyl ring, benzophenone-O,O'-disulfamates show increased activity. With an IC50 value of 190nM the 4,4'-derivative is the first small monocyclic STS inhibitor coming close to the potency of the steroidal standard estrone sulfamate. (C) 2002 Elsevier Science Ltd.
