  Structural Optimization of 2,5-Thiophene Amides as Highly Potent and Selective 17β-Hydroxysteroid Dehydrogenase Type 2 Inhibitors for the Treatment of Osteoporosis

  摘要：

  Inhibition of 17 beta-HSD2 is an attractive mechanism for the treatment of osteoporosis. We report here the optimization of human 17 beta-HSD2 inhibitors in the 2,5-thiophene amide class by varying the size of the linker (n equals 0 and 2) between the amide moiety and the phenyl group. While none of the phenethylamides (n = 2) were active, most of the anilides (n = 0) turned out to moderately or strongly inhibit 17 beta-HSD2. The four most active compounds showed an ICso of around 60 nM and a very good selectivity toward 17 beta-HSD1, 17 beta-HSD4, 17 beta-HSD5, 11 beta-HSD1, 11 beta-HSD2 and the estrogen receptors alpha and beta. The investigated compounds inhibited monkey 17 beta-HSD2 moderately, and one of them showed good inhibitory activity on mouse 17 beta-HSD2. SAR studies allowed a first characterization of the human 17 beta-HSD2 active site, which is predicted to be considerably larger than that of 17 beta-HSD1.

• Direct Cross-Coupling Access to Diverse Aromatic Sulfide: Palladium-Catalyzed Double C–S Bond Construction Using Na₂S₂O₃ as a Sulfurating Reagent

  The Pd-catalyzed cross-coupling of aryl halides, alkyl halides, and Na2S2O3 center dot 5H(2)O to deliver aromatic thioethers is described. Pyridine, furan, thiophene, benzofuran, benzoxazole, benzothiophene, benzothiazole, and pyrazine are all amenable to this protocol. The odorless and stable solid Na2S2O3 center dot 5H(2)O was used as a convenient and environmentally friendly source of sulfur. Pd-catalyzed cross-couplings without thiols or thiophenols to build C-S bonds have not previously been achieved, which renders our observation more striking.
