    • 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)。

    • The present invention relates to compounds of formula wherein R1 signifies hydrogen or lower alkyl; R2, R2′ signify, independently from each other, hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl; X signifies O, S or two hydrogen atoms not forming a bridge; A1/A2 signify, independently from each other, phenyl or a 6-membered heterocycle containing 1 or 2 nitrogen atoms; B is a group of formula  wherein R3 signifies lower alkyl, lower alkenyl, lower alkinyl, benzyl, lower alkyl-cycloalkyl, lower alkyl-cyano, lower alkyl-pyridinyl, lower alkyl-lower alkoxy-phenyl, lower alkyl-phenyl, which is optionally substituted by lower alkoxy, or phenyl, which is optionally substituted by lower alkoxy, or lower alkyl-thienyl, cycloalkyl, lower alkyl-trifluoromethyl or lower alkyl-morpholinyl, Y signifies —O—, —S— or a bond; Z signifies —O— or —S—; or B is a 5-membered heterocyclic group of formulas  wherein R4 and R5 signifies hydrogen, lower alkyl, lower alkoxy, cyclohexyl, lower alkyl-cyclohexyl or trifluoromethyl, with the proviso that at least one of R4 or R5 has to be hydrogen; as well as to their pharmaceutically acceptable salts. These compounds may be used in the control or prevention of acute and/or chronic neurological disorders such as restricted brain function caused by bypass operations or transplants, poor blood supply to the brain, spinal cord injuries, head injuries, hypoxia caused by pregnancy, cardiac arrest, hypoglycaemia, Alzheimer's disease, Huntington's chorea, ALS, dementia caused by AIDS, eye injuries, retinopathy, cognitive disorders, memory deficits, schizophrenia, idiopathic parkinsonism or parkinsonism caused by medicaments as well as conditions which lead to glutamate deficiency functions, such as e.g. muscle spasms, convulsions, migraine, urinary incontinence, nicotine addiction, psychoses, opiate addiction, anxiety, vomiting, acute and chronic pain, dyskinesia and depression.
