The present invention relates to compounds of formula I, wherein Y is N or C-R1'; R1' is hydrogen or F; R1 is hydrogen, halogen or lower alkyl substituted by halogen; R2 is hydrogen or lower alkyl; or R2 forms together with R4 a 6 membered heterocyclic ring containing -CH2-CH2-O-CH2- or -CH2-CH2-NR-C(O)-; R is hydrogen, lower alkyl, phenyl or benzyl; R3 is phenyl or pyridinyl, wherein the N atom in the pyridinyl group may be in different positions; R4' is hydrogen, lower alkyl or lower alkoxyalkyl; R4 is hydrogen, lower alkyl, phenyl optionally substituted by halogen or lower alkoxy, or is cycloalkyl, or is pyridinyl optionally substituted by halogen, lower alkyl, lower alkoxy or =0, or is pyrimidinyl optionally substituted by lower alkyl, lower alkoxy or =0, or is 1 -lower alkyl-pyridinyl, or is pyrazinyl, or is pyridazinyl optionally substituted by lower alkyl, lower alkoxy or =0, or is l-methylpyrrolo[2,3-b]pyridine-5-yl, or is 6-imidazo[l,2- b]pyridazin-6-yl; or R4 forms together with R4' a 4, 5 or 6 membered heterocyclic ring containing -(CH2)5-, -CH2-CH2-O-CH2-CH2-, -CH2-CH2-CH2-, -CH2-CH2-CH2-CH2-, -CH2-O-CH2-CH2- or CH2-CH2-CH2-O-CH2; R5 and R5' are hydrogen or lower alkyl; or R4 forms together with R5 a saturated 5- membered ring containing -CH2-CH2-CH2-; 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. The compounds may be used for the treatment of Parkinson's disease, anxiety, emesis, obsessive compulsive disorder, autism, neuroprotection, cancer, depression and diabetes type 2.
本发明涉及以下式I的化合物,其中Y为N或C-R1';R1'为氢或F;R1为氢、卤素或经卤素取代的较低烷基;R2为氢或较低烷基;或R2与R4一起形成一个含有-CH2-CH2-O-CH2-或-CH2-CH2-NR-C(O)-的6元杂环环;R为氢、较低烷基、苯基或苄基;R3为苯基或吡啶基,其中吡啶基中的N原子可能在不同位置;R4'为氢、较低烷基或较低烷氧基烷基;R4为氢、较低烷基、苯基(可选择地经卤素或较低烷氧基取代)、环烷基、或吡啶基(可选择地经卤素、较低烷基、较低烷氧基或=0取代)、或嘧啶基(可选择地经较低烷基、较低烷氧基或=0取代)、或1-较低烷基-吡啶基,或吡嗪基,或吡啶嗪(可选择地经较低烷基、较低烷氧基或=0取代),或1-甲基吡咯并[2,3-b]吡啶-5-基,或6-咪唑并[1,2-b]吡嗪-6-基;或R4与R4'一起形成含有-(CH2)5-、-CH2-CH2-O-CH2-CH2-、-CH2-CH2-CH2-、-CH2-CH2-CH2-CH2-、-CH2-O-CH2-CH2-或CH2-CH2-CH2-O-CH2-的4、5或6元杂环环;R5和R5'为氢或较低烷基;或R4与R5一起形成一个饱和的含有-CH2-CH2-CH2-的5元环;或制药学上可接受的盐或酸加成盐,或消旋混合物,或其相应的对映体和/或光学异构体和/或立体异构体。这些化合物可用于治疗帕金森病、焦虑、恶心、强迫性障碍、自闭症、神经保护、癌症、抑郁症和2型糖尿病。
