  Primary mono- and bis-sulfonamides obtained via regiospecific sulfochlorination of N-arylpyrazoles: inhibition profile against a panel of human carbonic anhydrases

  摘要：

  A diverse set of mono- and bis-sulfonamide was obtained via a direct, chemoselective sulfochlorination of readily available yet hitherto unexplored N-arylpyrazole template. Biochemical profiling of compounds thus obtained against a panel of human carbonic anhydrases (hCA I, hCA II, hCA IV and hCA VII) revealed a number of leads that are promising from the isoform selectivity prospective and exhibit potent inhibition profile (from nanomolar to micromolar range). The observed SAR trends have been rationalized by in silico docking of selected compounds into the active site of all four isoforms. The results reported in this paper clearly attest to the power of direct sulfochlorination as the means to create carbonic anhydrase focused sets in order to identify isoform selective inhibitors of closely related enzymes.

• From Sensors to Silencers: Quinoline- and Benzimidazole-Sulfonamides as Inhibitors for Zinc Proteases
  作者：Matthieu Rouffet、César Augusto F. de Oliveira、Yael Udi、Arpita Agrawal、Irit Sagi、J. Andrew McCammon、Seth M. Cohen

  sensors, chelating fragment libraries of quinoline- and benzimidazole-sulfonamides have been prepared and screened against several different zinc(II)-dependent matrix metalloproteinases (MMPs). The fragments show impressive inhibition of these metalloenzymes and preferences for different MMPs based on the nature of the chelating group. The findings show that focused chelator libraries are a powerful strategy

  olefins with arenesulfonyl and trifluoromethanesulfonyl chlorides. Thus (E)-1,2-disubstituted alkenes with high stereoselectivity and 1,1,2-disubstituted alkenes with 12:1 to 21:1 E/Z steroselectivity can be obtained. Herrmann's palladacycle at 0.1 mol % is sufficient to catalyze these reactions, for which electron-rich or electron-poor sulfonyl chlorides and alkenes are suitable. If phosphine- and base-free

  已经发现了新的条件，用于用芳烃磺酰氯和三氟甲烷磺酰氯对单取代和无取代的烯烃进行脱硫的Mizoroki-Heck芳基化和三氟甲基化。因此，可以获得具有高立体选择性的（E）-1,2-二取代的烯烃和具有12：1至21：1的E / Z立体选择性的1,1,2-二取代的烯烃。0.1摩尔％的赫尔曼（Hermann）的Palladacycle足以催化这些反应，对此，富电子或贫电子的磺酰氯和烯烃是合适的。如果需要无磷和无碱条件，则1摩尔％[RhCl（C（2）H（4））（2）]催化脱硫交叉偶联反应。与报道的[RuCl（2）（PPh（3））（2）]催化与磺酰氯偶联反应的结果相反，自由基清除剂不会抑制钯和铑的脱硫Mizoroki-Heck偶联反应。在Pd或Rh催化剂的存在下，在更高的温度下，烯烃在60摄氏度下磺酰化产生的可能的砜不会被脱硫。

  role in hepatocyte growth factor (HGF) signaling and epithelial integrity makes it a target of therapeutic interest in carcinogenesis and metastasis. Using an integrated design, synthesis, and screening platform, we were able to rapidly develop potent and selective inhibitors of hepsin. In progressing from the initial hit 7 to compound 53, the IC50 value against hepsin was improved from ∼1 μM to 22
