The present invention relates to ethynyl derivatives of formula I
wherein
Y is N or CH
R
1
is fluoro or chloro
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,其中Y为N或CHR1,R1为氟或氯,或其对应的光学异构体和/或立体异构体的药学可接受的酸加合物或外消旋混合物。令人惊讶的是,发现公式I的化合物是代谢型谷氨酸受体拮抗剂(负向变构调节剂),可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)。
