The present invention relates to ethynyl derivatives of formula (I) wherein U is N or CH, R8 is hydrogen, halogen, lower alkyl or lower alkoxy;Y is –N(R4)-, -O- or –C(R5R5')-; wherein R4 is hydrogen or lower alkyl and R5/R5' are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; V is –N(R6)- or –C(R7R7'), wherein R6 is hydrogen or lower alkyl and R7/R7' are independently from each other hydrogen, lower alkyl, CH2-lower alkoxy or may form together with the carbon atom to which they are attached a C3-C6-cycloalkyl; R1 is phenyl or heteroaryl, which are optionally substituted by halogen, lower alkyl or lower alkoxy; m is 0 or 1; in case m is 1, R3/R3' are independently from each other hydrogen, lower alkyl, CH2-lower alkoxy or may form together with the carbon atom to which they are attached a C3-C6-cycloalkyl; n is 0 or 1; in case n is 1, R2/R2' are independently from each other hydrogen, lower alkyl, CH2-lower alkoxy or may form together with the carbon atom to which they are attached a C3-C6-cycloalkyl; or if m is 1 and n is 0, R3 and R7 may form together with the carbon atoms to which they are attached a C4-6-cycloalkyl; or if m is 1 and n is 1, R2 and R3 or R3 and R7 may form together with the carbon atoms to which they are attached a C4-6-cycloalkyl; 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)的乙炔衍生物,其中U为N或CH,R8为氢、卤素、低烷基或低烷氧基;Y为-N(R4)-、-O-或-C(R5R5')-;其中R4为氢或低烷基,R5/R5'分别独立地为氢、羟基、低烷基或低烷氧基;V为-N(R6)-或-C(R7R7'),其中R6为氢或低烷基,R7/R7'独立地为氢、低烷基、CH2-低烷氧基或可能与其附着的碳原子一起形成C3-C6环烷基;R1为苯或杂环烷基,可以选择性地被卤素、低烷基或低烷氧基取代;m为0或1;如果m为1,则R3/R3'独立地为氢、低烷基、CH2-低烷氧基或可能与其附着的碳原子一起形成C3-C6环烷基;n为0或1;如果n为1,则R2/R2'独立地为氢、低烷基、CH2-低烷氧基或可能与其附着的碳原子一起形成C3-C6环烷基;或者如果m为1且n为0,R3和R7可以与其附着的碳原子一起形成C4-6环烷基;或者如果m为1且n为1,R2和R3或R3和R7可以与其附着的碳原子一起形成C4-6环烷基;或者是其对应的药用酸盐、消旋混合物,或其相应的对映体和/或光学异构体和/或立体异构体。已经发现,一般式(I)的化合物是代谢型谷氨酸受体亚型5(mGluR5)的别构调节剂。
