  Potent mGluR5 antagonists: Pyridyl and thiazolyl-ethynyl-3,5-disubstituted-phenyl series

  摘要：

  We report the synthesis of four series of 3,5-disubstituted-phenyl ligands targeting the metabotropic glutamate receptor subtype 5: (2-methylthiazol-4-yl)ethynyl (1a-j,), (6-methylpyridin-2-yl)ethynyl (2a-j), (5-methylpyridin-2-yl)ethynyl (3a-j,), and (pyridin-2-yl)ethynyl (4a-j,). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro assay. All compounds were found to be full antagonists and exhibited low nanomolar to subnanomolar activity. (C) 2011 Elsevier Ltd. All rights reserved.

  focuses on the development of practical approaches to the in situ generation of anhydrous fluoride salts for applications in nucleophilic aromatic substitution (SNAr) reactions. We report herein that a variety of combinations of inexpensive nucleophiles (e.g., tetraalkylammonium cyanide and phenoxide salts) and fluorine-containing electrophiles (e.g., acid fluoride, fluoroformate, benzenesulfonyl fluoride

• Effect of Leaving Group Substituents on the Microfluidic Synthesis of [18F]3-Fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile ([18F]FPEB)

  A commercial microfluidic reactor system has been used to synthesize the mGLUR5 receptor imaging agent [F-18]FPEB. To study the effect of leaving group substituents on the synthesis of the desired compound, the chloro-, bromo-, iodo-, and nitro-substituted precursors for FPEB were evaluated. Precursor concentrations of 4 - 10 mg/mL were evaluated in various solvents, with temperature ranges between 120 and 220 degrees C, and total processing times of less than five minutes. Optimized incorporation yields ranged from 5% to 69.4% depending on the precursor used.
