摘要:
The present invention relates to compounds of formula I wherein Y is N or C-R 1' ; G is a 5 or 6-membered aromatic or heteroaromatic ring containing 0, 1, 2 or 3 heteroatoms, selected from the group consisting of phenyl, pyridinyl with different N-positions, imidazolyl, pyrazinyl, pyrimidinyl, thiophenyl, thiazolyl, pyrazolyl or thiadiazolyl, which are optionally substituted by 1, 2 or 3 substituents, selected from the group consisting of halogen, lower alkyl, lower alkoxy, lower alkoxy substituted by halogen or NRR'; R and R' are independently from each other hydrogen or lower alkyl, or may form together with the N atom to which they are attached a five or six membered saturated heterocyclic group which may contain an additional oxygen, NH, or N-lower alkyl group; R 1 is hydrogen, halogen or lower alkyl substituted by halogen; R 1' is hydrogen, halogen or lower alkyl substituted by halogen; R 2 is hydrogen, lower alkyl, lower alkoxyalkyl, cycloalkyl or heterocycloalkyl; or R 2 may form together with the closest carbon atom in group G a group (IA) for A being -CH 2 -, -CH 2 CH 2 , or -C(CH 3 ) 2 -, R 3 is phenyl or pyridinyl, wherein the N atom in the pyridinyl group may be in different positions; or to a pharmaceutically acceptable salt or acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof. It has been surprisingly been found that the compounds of general formula I are positive allosteric modulators (PAMs) of metabotropic glutamate receptor 4 (mGluR4), useful for the treatment of Parkinson's disease, anxiety, emesis, obsessive compulsive disorder, autism, neuroprotection, cancer, depression and diabetes type 2.

摘要:
The present invention relates to ethynyl derivatives of formula (I) wherein Y is N or CH; R 1 is hydrogen, fluoro or chloro; and R 2 is hydrogen or lower alkyl; or to a pharmaceutically acceptable acid addition salt 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 syndrome, autism spectrum disorders, Parkinson's disease, and gastroesophageal reflux disease (GERD).
摘要:
The present invention relates to ethynyl derivatives of formula (I) wherein U is N or CH, R 8 is hydrogen, halogen, lower alkyl or lower alkoxy;Y is –N(R 4 )-, -O- or –C(R 5 R 5 ')-; wherein R4 is hydrogen or lower alkyl and R 5 /R 5' are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; V is –N(R 6 )- or –C(R 7 R 7' ), wherein R6 is hydrogen or lower alkyl and R 7 /R 7' are independently from each other hydrogen, lower alkyl, CH 2 -lower alkoxy or may form together with the carbon atom to which they are attached a C 3 -C 6 -cycloalkyl; R 1 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, R 3 /R 3' are independently from each other hydrogen, lower alkyl, CH 2 -lower alkoxy or may form together with the carbon atom to which they are attached a C 3 -C 6 -cycloalkyl; n is 0 or 1; in case n is 1, R 2 /R 2' are independently from each other hydrogen, lower alkyl, CH 2 -lower alkoxy or may form together with the carbon atom to which they are attached a C 3 -C 6 -cycloalkyl; or if m is 1 and n is 0, R 3 and R 7 may form together with the carbon atoms to which they are attached a C 4-6 -cycloalkyl; or if m is 1 and n is 1, R 2 and R 3 or R 3 and R 7 may form together with the carbon atoms to which they are attached a C 4-6 -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).
