  A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.

  the metal-promoted tandem nitration and halogenation of N-phenylbenzenesulfonamide to synthesize N-(4-halo-2-nitrophenyl)benzenesulfonamide derivatives has been developed. The method shows highly practical chemoselective and functional group compatibility. In addition, it employs insensitive and inexpensive Cu(NO3)2·3H2O, Fe(NO3)3·9H2O, and NH4NO3 as the nitration reagents, and it provides a direct

• Toward Optimization of the Linker Substructure Common to Transthyretin Amyloidogenesis Inhibitors Using Biochemical and Structural Studies

  To develop potent and highly selective transthyretin (TTR) amyloidogenesis inhibitors, it is useful to systematically optimize the three substructural elements that compose a typical TTR kinetic stabilizer: the two aryl rings and the linker joining them. Herein, we evaluated 40 bisaryl molecules based on 10 unique linker substructures to determine how these linkages influence inhibitor potency and selectivity. These linkers connect one unsubstituted aromatic ring to either a 3,5-X 2 or a 3,5-X 2-4-OH phenyl substructure (X = Br or CH 3). Coconsideration of amyloid inhibition and ex vivo plasma TTR binding selectivity data reveal that direct connection of the two aryls or linkage through nonpolar E-olefin or -CH 2CH 2- substructures generates the most potent and selective TTR amyloidogenesis inhibitors exhibiting minimal undesirable binding to the thyroid hormone nuclear receptor or the COX-1 enzyme. Five high-resolution TTR.inhibitor crystal structures (1.4-1.8 A) provide insight into why such linkers afford inhibitors with greater potency and selectivity.

  The synthesized sulfonamides were evaluated for cytotoxicity followed by the cytokine/inflammatory marker’s inhibition capability and its mechanism of action in RAW‐264.7 cells. Elevated interleukin‐6 (IL‐6) levels have been reported in inflammatory conditions and inflammation‐associated disorders. Hence, reducing the IL‐6 levels in inflammatory conditions can serve as an attractive therapeutic target in dealing the inflammation. Among 42 compounds, seven compounds showed significant inhibition of IL‐6 levels in lipopolysaccharide (LPS) challenged RAW‐264.7 cells at 12.5 µM concentration. Further, investigation revealed that the IC50 value of these compounds for reducing IL‐6 levels was found to be in the range of 9.7 to 2.6 µM. The promising compounds 5y (IC50 of 2.6 µM) and 5n (IC50 of 4.1 µM) along with other derivatives fulfil drug‐likeness parameters laid down by Lipinski’s rule of five. Further, analysis using RTqPCR and Western‐blot analysis revealed that treatment with 5n significantly reduced the expression of pro‐inflammatory, inflammatory and macrophage marker’s expression (IL‐1β, CCL2, COX2 and CD68) compared to LPS control. The mechanistic evaluation showed that RL‐442 exhibited anti‐inflammatory properties by modulating the nuclear factor‐κB (NF‐κB) activation. The identified compound can be a promising candidate for further discovery efforts to generate a preclinical candidate effective in inflammation.

  A highly efficient intramolecular selective aryl migration/desulfonylation of 2-bromo-N-aryl-N-(arenesulfonyl)amide via visible light-induced photoredox catalysis has been accomplished. This approach allows for the construction of a variety of multisubstituted N,2-diarylacetamide under mild reaction conditions.
