The present invention relates to ethynyl derivatives of formula I
wherein
Y is N or CH
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 syndrome, 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,其中Y为N或CH,或其药学上可接受的酸加成盐,或其相应的外消旋体混合物,或其对映体和/或光学异构体和/或立体异构体。现已惊奇地发现,通式I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综合症、自闭症谱系障碍、帕金森病和胃食管反流病(GERD)。
