The present invention relates to compounds of formula (I) wherein Y is C-R1; R1 is hydrogen or halogen; R1 is hydrogen or halogen; R2 is hydrogen, lower alkyl or phenyl,; R4 is hydrogen or lower alkyl; or R2 and R4 may form together with the corresponding atoms, to which they are attached the following rings: (A), (B), (C), (D) or (E); R5 is hydrogen or lower alkyl; and if R2 and R4 form a ring as described above, than R5 is hydrogen; or R4 and R5 may form together with the C-atom to which they are attached a heterocycloalkyl ring; R3 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. 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.
本发明涉及式(I)的化合物,其中Y为C-R1; R1为氢或卤素; R1为氢或卤素; R2为氢,低级烷基或苯基; R4为氢或低级烷基; 或R2和R4可以与它们所附着的相应原子一起形成以下环:(A),(B),(C),(D)或(E); R5为氢或低级烷基; 如果R2和R4形成上述环,则R5为氢; 或者R4和R5可以与它们所附着的C原子一起形成杂环烷基环; R3为苯基或吡啶基,其中吡啶基中的N原子可以处于不同的位置; 或者是其药学上可接受的盐或酸加成盐,其外消旋混合物,或其对应的对映体和/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、焦虑症、恶心、强迫症、自闭症、神经保护、癌症、抑郁症和2型糖尿病。
