- N-Acyl arylsulfonamides as novel, reversible inhibitors of human steroid sulfatase
-
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 Ki = 76 nM), they showed only weak inhibition of STS activity in cells (lowest IC50 around 2 μM). 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).

- N-(phenylsulfonyl)picolinamide derivatives, process for producing the same, and herbicide
-
A herbicide containing as the active ingredient an N-(henylsulfonyl)picolinamide derivative represented by general formula (I) wherein X reprcsents a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, a C1-4 haloalkoxy, a (C1-4 alkoxy)carbonyl, a [di(C1-4 alkyl)amino]sulfonyl, an [N—(C1-4 alkyl)-N—(C1-4 alkoxy)amino]sulfonyl, a (C1-4 alkylamino)sulfonyl, a C1-4 alkylthio, a C1-4 alkylsulfinyl, a C1-4 alkylsulfonyl, or nitro; n is an integer of 0 to 5; Y represets a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, C1-4 haloalkoxy, a C1-4 alkylthio, a C1-4 haloalkylthio, amino, a C1-4 alkylamino, a di(C1-4 alkyl)amino, a (C1-4 alkoxy) C1-4 alkyl, a (C1-4 alkylthio) C1-4 alkyl, or nitro; and m is an integer of 0 to 4. This active ingredient is synthesized by condensing a substituted picolinic acid with a substituted benzenesulfonamide under dehydration, or by reacting the phenyl ester of a substituted picolinic acid with a substituted benzenesulfonamide in the presence of a basic compound.
