The present invention relates to compounds of general formula (I) wherein R1 is aryl or heteroaryl, which are optionally substituted by one, two or three substituents, selected from lower alkyl, halogen, lower alkyl substituted by halogen, hydroxy, lower alkyl substituted by hydroxy, lower alkoxy, lower alkoxy substituted by halogen, cyano or nitro; R 2 is halogen, lower alkyl or cyano; R 3 is hydrogen, lower alkyl or lower alkyl substituted by halogen; R 4 is hydrogen or lower alkyl; R5, R 6 are hydrogen, lower alkyl, or may form together with the N-atom to which they are attached a heterocycloalkyl ring; or a pharmaceutically acceptable acid addition salt, a racemic mixture or its corresponding enantiomer and/or optical isomers thereof. The compounds may be used for the treatment of schizophrenia, obsessive-compulsive personality disorder, major depression, bipolar disorders, anxiety disorders, normal aging, epilepsy, retinal degeneration, traumatic brain injury, spinal cord injury, post-traumatic stress disorder, panic disorder, Parkinson's disease, dementia, Alzheimer's disease, cognitive impairment, chemotherapy-induced cognitive dysfunction ("chemobrain"), Down syndrome, autism spectrum disorders, hearing loss, tinnitus, spinocerebellar ataxia, amyotrophic lateral sclerosis, multiple sclerosis, Huntington's disease, stroke, and disturbances due to radiation therapy, chronic stress, or abuse of neuro-active drugs, selected from alcohol, opiates, methamphetamine, phencyclidine and cocaine.
本发明涉及通式(I)的化合物,其中R1是芳基或杂环芳基,可以选择地被一个、两个或三个取代基取代,所选取代基包括较低的烷基、卤素、被卤素取代的较低的烷基、羟基、被羟基取代的较低的烷基、烷氧基、被卤素取代的烷氧基、氰基或硝基;R2是卤素、较低的烷基或氰基;R3是氢、较低的烷基或被卤素取代的较低的烷基;R4是氢或较低的烷基;R5、R6是氢、较低的烷基,或者可以与它们附着的N原子一起形成一个杂环烷基环;或者是药学上可接受的酸盐加合物,外消旋混合物或其对应的对映体和/或光学异构体。这些化合物可用于治疗精神分裂症、强迫性人格障碍、重度抑郁症、躁郁症、焦虑障碍、正常衰老、癫痫、视网膜退行性疾病、创伤性脑损伤、脊髓损伤、创伤后应激障碍、恐慌障碍、帕金森病、痴呆症、阿尔茨海默病、认知障碍、化疗诱导的认知功能障碍("化疗脑")、唐氏综合征、自闭症谱系障碍、听力丧失、耳鸣、脊髓小脑共济失调、肌萎缩性侧索硬化、多发性硬化症、亨廷顿病、中风,以及由放疗、慢性压力或神经活性药物(包括酒精、鸦片、甲基苯丙胺、芬太尼和可卡因)滥用引起的干扰。
