Fe/ppm Pd nanoparticles and PEG‐containing designer surfactants, a facile and selective reduction of nitro‐containing aromatics and heteroaromatics can be effected in water at roomtemperature in the presence of NaBH4. This new nanotechnology involves lowcatalystloadings, is highly chemoselective, and tolerates a wide variety of functional groups. The process, which includes recycling of the entire

We previously identified phenylquinoxalinone CFTRact-J027 (4) as a cysticfibrosistransmembraneconductanceregulator (CFTR) activator with an EC50 of ∼200 nM and demonstrated its therapeutic efficacy in mouse models of constipation. Here, structure–activity studies were done on 36 synthesized phenylquinoxalinone analogs to identify compounds with improved potency and altered metabolic stability.

Synthesis of Fused Imidazoles and Benzothiazoles from (Hetero)Aromatic <i>ortho</i>-Diamines or <i>ortho</i>-Aminothiophenol and Aldehydes Promoted by Chlorotrimethylsilane
New convenient conditions for benzimidazole and benzothiazole syntheses are described. A set of benzimidazoles, 3H-imidazo[4,5-b]pyridines, purines, xanthines and benzothiazoles was readily prepared from (hetero)aromatic ortho-diamines or ortho-aminothiophenol and aldehydes using chlorotrimethylsilane in DMF as a promoter and water-acceptor agent, followed by oxidation with air oxygen.

exhibited antiproliferative effects against a panel of cancer cell lines. Compound 7 was the most potent selective inhibitor of HDAC6 and had an IC50 value 8- to >111.1-fold those of HDAC3, HDAC4, HDAC8, and HDAC11, and was a superior HDAC6 inhibitor to belinostat. Its interaction with and inhibitory activity on HDAC enzymes were then explored in a molecular docking study. The obtained data revealed the highest
