The present invention relates to ethynyl derivatives of formula I wherein Y is N or CH; with the proviso that Y can only be CH, if at least on of U, V or W are N; U is N or C-R4; V and W are independently N or CH; with the proviso that only one of U, V or W can be simultaneously nitrogen; R4 is hydrogen, methyl or halogen; R1 is phenyl or heteroaryl, which are optionally substituted by halogen, lower alkyl or lower alkoxy; R is hydrogen or lower alkyl; R2 is hydrogen, lower alkyl, lower alkoxy, CF3 or S-lower alkyl; are independently from each other hydrogen, lower alkyl or lower alkoxy; or R3 and R3 form together a C3-5-cycloalkyl-, tetrahydrofuran- or an oxetane-ring; 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 been found that the compounds of general formula I are allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5).
本发明涉及公式I的乙炔基衍生物,其中Y是N或CH;条件是,如果至少U、V或W中的一个是N,则Y只能是CH;U是N或C-R4;V和W独立地为N或CH;条件是U、V或W中只能同时有一个是氮;R4是氢、甲基或卤素;R1是苯基或杂芳基,它们可被卤素、低级烷基或低级烷氧基取代;R是氢或低级烷基;R2是氢、低级烷基、低级烷氧基、CF3或S-低级烷基;它们独立地是氢、低级烷基或低级烷氧基;或者R3和R3共同形成一个C3-5-环烷基、四氢呋喃或环氧环烷环;或者是一种药用可接受的酸加成盐,是一种外消旋混合物,或者是其相应的对映体和/或光学异构体和/或立体异构体。研究发现,通用公式I的化合物是代谢型谷氨酸受体亚型5(mGluR5)的别构调节剂。
