The present invention relates to pharmaceutical compositions comprising an inhibitor of epithelial sodium channel activity in combination with at least one ABC Transporter modulator compound of Formula A, Formula B, Formula C, or Formula D. The invention also relates to pharmaceutical formulations thereof, and to methods of using such compositions in the treatment of CFTR mediated diseases, particularly cystic fibrosis using the pharmaceutical combination compositions.
Conanoparticles (NPs) encapsulated in N‐dopedcarbonnanotubes (Co@NC900) are systematically investigated as a potential alternative to precious Pt‐group catalysts for hydrogenative heterocyclization reactions. Co@NC900 can efficiently catalyze hydrogenative coupling of 2‐nitroaniline to benzaldehyde for synthesis of 2‐phenyl‐1H‐benzo[d]imidazole with >99 % yield at ambient temperature in one step

One-pot reduction-triggered heterocyclizations from 2-nitroanilines or 1,2-dinitroarenes to benzimidazoles were investigated in this study. In the presence of indium/AcOH in ethyl acetate at reflux, reaction of 2-nitroanilines or 1,2-dinitroarenes with R–C(OMe)3 (R=Me, Ph) produced excellent yields of the corresponding benzimidazoles within 30 min to 6 h depending on the substituents of the starting
Air-stable Ruthenium(II)-NNN Pincer Complexes for the Efficient Coupling of Aromatic Diamines and Alcohols to 1<i>H</i>
-benzo[<i>d</i>
]imidazoles with the Liberation of H<sub>2</sub>
Two new phosphine‐free RuII‐NNN pincer complexes ([RuCl(L1)(CH3CN)2]Cl (1) and [RuCl(L2)(CH3CN)2]Cl (2) [L1=2,6‐bis(1H‐imidazole‐2‐yl)pyridine, L2=2,6‐bis(1‐hexyl‐1H‐imidazole‐2‐yl)pyridine] were synthesized to catalyze the condensation of benzyl alcohol and benzene‐1,2‐diamine homogeneously to 2‐pheny‐1H‐benzo[d]imidazole and H2. The reactivity in the order of 1>2 is lower than that of the phosphine‐containing

mebendazole.10 Similarly, benzoxazole is the core ring structure in the non-steroidal anti-inflammatory drug flunoxaprofen,11 while the benzothiazole unit is found in zopolrestat12 and riluzole,13 which are used to treat diabetes. Current strategies to prepare these ring systems involve oxidative cyclizations of Schiff bases,14–22 metal-catalyzed amide cyclizations23–25 and reaction of o-substituted
