  Synthesis and Structure−Activity Relationships of 3-[(2-Methyl-1,3-thiazol-4-yl)ethynyl]pyridine Analogues as Potent, Noncompetitive Metabotropic Glutamate Receptor Subtype 5 Antagonists; Search for Cocaine Medications

  摘要：

  Recent genetic and pharmacological studies have suggested that the metabotropic glutamate receptor subtype 5 (mGluR5) may represent a druggable target in identifying new therapeutics for the treatment of various central nervous system disorders including drug abuse. In particular, considerable attention in the mGluR5 field has been devoted to identifying ligands that bind to the allosteric modulatory site, distinct from the site for the primary agonist glutamate. Both 2-methyl-6-(phenylethynyl)pyridine (MPEP) and its analogue 3-[(2-methyl-4-thiazolyl)ethynyl]pyridine (MTEP) have been shown to be selective and potent noncompetitive antagonists of mGluR5. Because of results presented in this study showing that MTEP prevents the reinstatement of cocaine self-administration caused by the presentation of environmental cues previously associated with cocaine availability, we have prepared a series of analogues of MTEP with the aim of gaining a better understanding of the structural features relevant to its antagonist potency and with the ultimate aim of investigating the effects of such compounds in blunting the self-administration of cocaine. These efforts have led to the identification of compounds showing higher potency as mGluR5 antagonists than either MPEP or MTEP. Two compounds 19 and 59 exhibited functional activity as mGluR5 antagonists that are 490 and 230 times, respectively, better than that of MTEP.

  dihalo 1,3-thiazole derivatives can be efficiently and selectively prepared under mild conditions from 2-amino-1,3-thiazoles. Halogenations proceed easily in the presence of copper(I) or copper(II) chlorides, bromides, or iodides directly in solution or with supported copper halides.

  单卤和二卤 1,3-噻唑衍生物可以在温和条件下由 2-氨基-1,3-噻唑高效且选择性地制备。在铜 (I) 或铜 (II) 氯化物、溴化物或碘化物直接存在于溶液中或与负载的卤化铜一起存在时，卤化很容易进行。

  [EN] Antagonists of group 1 metabotropic glutamate receptors (mGluR) potentiate the effect of positive AMPA receptor modulators on neurotrophin expression, such as brain-derived neurotrophic factor (BDNF). The findings described herein suggest a combinatorial approach for drug therapies, using both positive AMPA receptor modulators and mGluR antagonists, to enhance brain neurotrophism.
  [FR] Selon l'invention, les antagonistes des récepteurs métabotropiques du glutamate (mGluR) du groupe 1 potentialisent l'effet positif des modulateurs des récepteurs AMPA sur l'expression de neurotrophines telles que le facteur neurotrophique dérivé du cerveau (BDNF). Les découvertes décrites dans la présente invention suggèrent pour les thérapies médicamenteuses une approche combinatoire utilisant à la fois des modulateurs positifs des récepteurs AMPA et des antagonistes des récepteurs mGluR pour renforcer le neurotropisme cérébral.
