  The present invention relates to ethynyl derivatives of formula (I) or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof. It has now surprisingly been found that the compounds of general formula (I) are metabotropic glutamate receptor antagonists (negative allosteric modulators) for use in the treatment of anxiety and pain, depression, Fragile-X syndrom, autism spectrum disorders, Parkinson's disease, and gastroesophageal reflux disease (GERD).

  本发明涉及公式(I)的乙炔衍生物或药学上可接受的酸盐，或其相应的外消旋混合物，或其对映体和/或光学异构体和/或立体异构体。令人惊讶地发现，通式(I)的化合物是代谢型谷氨酸受体拮抗剂（负向变构调节剂），用于治疗焦虑和疼痛、抑郁症、脆性X综合征、自闭症谱系障碍、帕金森病和胃食管反流病（GERD）。
