    • The present invention relates to ethynyl derivatives of formula I wherein Y is N or C—R3; R3 is hydrogen, methyl, halogen or nitrile; R1 is phenyl or pyridinyl, each of which is optionally substituted by halogen, lower alkyl or lower alkoxy; R2/R2′ are each independently hydrogen, lower alkyl or lower alkyl substituted by halogen, or R2 and R2′ together with the N-atom to which they are attached form a morpholine ring, a piperidine ring or an azetidine ring, each of which is unsubstituted or substituted one or more substituents selected from lower alkoxy, halogen, hydroxy and methyl; R4/R4′ are each independently hydrogen or lower alkyl, or R4 and R4′ together form 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. Compounds of formula I are positive allosteric modulators (PAM) of the metabotropic glutamate receptor subtype 5 (mGluR5).
    • 本发明涉及式I的乙炔基衍生物,其中Y是N或C-R3; R3是氢,甲基,卤素或腈; R1是苯基或吡啶基,其各自任选被卤素,低级烷基或低级烷氧基取代; R2 / R2'各自独立地为氢,被卤素取代的低级烷基或低级烷基,或R2和R2'与它们所连接的N-原子一起形成吗啉环,哌啶环或氮杂环丁烷环,其中每个 未取代或取代的一个或多个选自低级烷氧基,卤素,羟基和甲基的取代基; R 4 / R 4'各自独立地为氢或低级烷基,或者R 4和R 4'一起形成C 3-5环烷基,四氢呋喃或氧杂环丁烷环; 或其药学上可接受的酸加成盐,或其相应的对映异构体和/或其旋光异构体和/或立体异构体。 式I化合物是代谢型谷氨酸受体亚型5(mGluR5)的正变构调节剂(PAM)。
