Anxiolytic-like Effects of N,N-Dialkyl-2-phenylindol-3-ylglyoxylamides by Modulation of Translocator Protein Promoting Neurosteroid Biosynthesis
摘要:
Novel N,N-disubstituted indol-3-ylglyoxylamides (1-56), bearing different combinations of substituents R-1-R-5, were synthesized and evaluated as ligands of the translocator protein (TSPO), the 18 kDa protein representing the minimal functional unit of the "peripheral-type benzodiazepine receptor" (PBR). Most of the new compounds showed a nanomolar/subnanomolar affinity for TSPO and stimulated steroid biosynthesis in rat C6 glioma cells with a potency similar to or higher than that of classic TSPO ligands such as PK 11195. Moreover, when evaluated in vivo by means of the elevated-plus-maze (EPM) paradigm in the rat, compound 32. the best-performing derivative in terms of TSPO affinity and pregnenolone production, showed clear anxiolytic effects. The results of this study suggested that the novel N, N-di substituted indol-3y1glyoxylani ides may represent a promising class of compounds potentially suited for the treatment of anxiety disorders.

A new and intriguing methodology to access various O‐difluoromethylation oxime compounds from ClCF2H, TBN and indoles is developed under mild reaction conditions. This strategy can suppress N‐difluoromethylation of indoles successfully, in which there are two different active species (:CF2 and ·NO) while indoles are unprotected, featuring simple operation and radical involvement.

Palladium-Catalyzed Asymmetric Intramolecular Dearomative Heck Annulation of Aryl Halides to Furnish Indolines
An unprecedented Pd-catalyzed asymmetric intramolecular cascade cyclization of aryl halides with readily available arylboronic acids proceeds through a Heck-type dearomative cyclization terminated with arylation in the presence of Pd2(dba)3 (10 mol %), Cu2O (5 mol %), and Cs2CO3 (2.0 equiv) in 1,2-dichloroethane (1.0 mL) at 100 °C for 15 h in air using BINOL-based phosphoramidite as the chiral ligand

arylation and alkenylation of tertiary amines with aryl and alkenylboronic acids is enabled by difluorocarbene under transition-metal-free conditions. This protocol represents a novel reaction mode which succeeded in the construction of Csp3−Csp2 bonds via an in situ formed nitrogen ylide from tertiary amines (propargylamines, allylamines and 1H-indol-3-yl methane amines) and difluorocarbene with aryl and
