  N-Acyl arylsulfonamides as novel, reversible inhibitors of human steroid sulfatase

  摘要：

  Steroid sulfatase (STS) is an attractive target for a range of oestrogen- and androgen-dependent diseases. In search of novel chemotypes of STS inhibitors, we had previously identified nortropinyl-arylsulfonylureas 1; however, while these compounds were good inhibitors of purified STS (lowest K-i = 76 nM), they showed only weak inhibition of STS activity in cells (lowest IC50 around 2 muM). Extended structure-activity relationship studies involving modification of the phenylacetyl side chain and replacement of the nortropine element by simpler scaffolds led to the discovery of N-acyl arylsulfonamides, more specifically N-(Boc-piperidine-4-carbonyl)-benzenesulfonamides, as STS inhibitors, some of which exhibit improved cellular potency (best IC50 = 270 nM).

While, from 3-bromoindole derivatives, 2-aryl-3-bromoindoles were obtained without debromination, and could be converted into 2,3-diarylindoles through a second palladium coupling.
