Cyclic iminium salts derived from dihydroisoquinolines, quinolines, and pyridines were successfully difluoromethylated with sulfur-based fluoroalkyl silanes affording a series of new difluoromethylated nitrogen-containing heterocyclic compounds.

Synthesis of 5-trifluoromethyl-2-sulfonylpyridine PPARbeta/delta antagonists: Effects on the affinity and selectivity towards PPARbeta/delta

The covalent modification of peroxisome-proliferator activated receptor beta/delta (PPARbeta/delta) is part of the mode of action of 5-trifluoromethyl-2-sulfonylpyridine PPARbeta/delta antagonists such as GSK3787 and CC618. Herein, the synthesis and in vitro biological evaluation of a range of structural analogues of the two antagonists are reported. The new ligands demonstrate that an improvement in the selectivity of 5-trifluoromethyl-2-sulfonylpyridine antagonists towards PPARbeta/delta is achievable at the expense of their immediate affinity for PPARbeta/delta. However, their putatively covalent and irreversible mode of action may ensure their efficacy over time, as observed in time-resolved fluorescence resonance energy transfer (TR-FRET)-based ligand displacement assays.

PARP inhibition treatment in a nonconventional experimental mouse model of chronic asthma

Allergic asthma is an immunological disease that occurs as a consequence of aeroallergen exposure. Inhibition of poly(ADP-ribose) polymerases (PARPs) in conventional models of asthma-like reaction has emerged as an effective anti-inflammatory and airway remodeling intervention. In a house dust mite (HDM) exposure mouse model, we investigated the impact of PARP inhibition on allergic airway inflammation, sensitization, and remodeling. Mice were intranasally exposed to a HDM extract for 5?days per week for up to 5?weeks. Mice were administered, or not, by PARP inhibitors 3-aminobenzamide (3-ABA) or 5-aminoisoquinolinone (5-AIQ) during the last 2?weeks of HDM treatment. Mice treated with PARP inhibitors after HDM stimulation showed a significant decrease in the number of total cells and eosinophils detectable in the bronchoalveolar lavage fluid as compared with the HDM-stimulated ones. In vitro HDM-stimulated splenocyte culture produced considerable amounts of the Th2 cytokines that were not affected by treatment with PARP inhibitors. Immunoglobulin levels in the serum were also unchanged. In the lung tissue, collagen deposition was decreased, whereas alpha-smooth muscle actin thickening was not significantly affected. Moreover, in HDM-stimulated PARP inhibitor-treated groups, we found a downregulation in the activation of signal transducer and activator of trascription-6 (STAT-6) and a significant decrease in the mRNA levels of C-C motif chemokine 11 (CCL11). In this mouse model of chronic asthma PARP inhibition treatment, although it does not affect sensitization, it effectively reduces the allergic airway inflammation and affects the remodeling through a mechanism involving STAT6 and CCL11.

Photoredox-Catalyzed Redox-Neutral Minisci C?H Formylation of N-Heteroarenes

We report a protocol for redox-neutral Minisci C?H formylation of N-heteroarenes using 1,3-dioxoisoindolin-2-yl 2,2-diethoxyacetate as a formyl equivalent at room temperature. This scalable benchtop protocol offers a distinct advantage over traditional reductive carbonylation and Minisci C?H formylation methods in not requiring the use of carbon monoxide, pressurized gas, a stoichiometric reductant, or a stoichiometric oxidant.
