  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.

  The present invention is directed to isotopically labeled alkyne derivative compounds, particularly 11 C, 13 C, 14 C, 18 F, 15 O, 13 N, 35 S, 2 H, and 3 H labeled compounds. In particular, the present invention is directed to 11 C, 13 C, 14 C, 18 F, 15 O, 13 N, 35 S, 2 H, and 3 H labeled heterocyclic alkynes and methods of their preparation. The present invention further includes a method of use of the 11 C, 18 F, 15 O, or 13 N labeled heterocyclic alkyne compounds as tracers in positron emission tomography (PET) imaging, particularly in the study of metabolic conditions in mammals, specifically conditions modulated by metabotropic glutamate receptors subtype 5 (mGluR5).

  本发明涉及同位素标记的炔基衍生物化合物，特别是11C、13C、14C、18F、15O、13N、35S、2H和3H标记的化合物。具体而言，本发明涉及11C、13C、14C、18F、15O、13N、35S、2H和3H标记的杂环炔烃及其制备方法。本发明还包括将11C、18F、15O或13N标记的杂环炔烃化合物用作正电子发射断层扫描（PET）成像中的示踪剂的使用方法，特别是在哺乳动物代谢状况的研究中，特别是通过代谢型谷氨酸受体亚型5（mGluR5）调节的状况。
