The invention relates to compounds of formula wherein R1 is hydrogen or phenyl, optionally substitutes by halogen, CN or lower alkoxy or lower alkoxy substituted by halogen; R2 is hydrogen or lower alkyl; R3 is hydrogen or lower alkyl or is phenyl optionally substituted by one or more substituents, selected from halogen, cyano or lower alkoxy substituted by halogen, or is pyridinyl, optionally substituted by halogen or lower alkyl substituted by halogen, or is pyrimidinyl, optionally substituted by lower alkyl substituted by halogen, or is pyrazinyl, optionally substituted by halogen, cyano or lower alkyl substituted by halogen; R4 is hydrogen, lower alkyl or phenyl; Z is a bond, -CH2- or -O-; or to a pharmaceutically suitable acid addition salt thereof. It has now been found that the compounds of formulas IA and IB have a good affinity to the trace amine associated receptors (TAARs), especially for TAAR1. The compounds may be used for the treatment of depression, anxiety disorders, bipolar disorder, attention deficit hyperactivity disorder (ADHD), stress-related disorders, psychotic disorders such as schizophrenia, neurological diseases such as Parkinson's disease, neurodegenerative disorders such as Alzheimer's disease, epilepsy, migraine, hypertension, substance abuse and metabolic disorders such as eating disorders, diabetes, diabetic complications, obesity, dyslipidemia, disorders of energy consumption and assimilation, disorders and malfunction of body temperature homeostasis, disorders of sleep and circadian rhythm, and cardiovascular disorders.
该发明涉及以下式中的化合物,其中R1是氢或苯基,可选择由卤素、CN或较低的烷氧基或由卤素取代的较低的烷氧基取代;R2是氢或较低的烷基;R3是氢或较低的烷基或是苯基,可选择由卤素、氰基或由卤素取代的较低的烷氧基取代,或是吡啶基,可选择由卤素或由卤素取代的较低的烷基取代,或是嘧啶基,可选择由较低的烷基取代的较低的烷基取代,或是吡嗪基,可选择由卤素、氰基或由卤素取代的较低的烷基取代;R4是氢、较低的烷基或苯基;Z是键,-CH2-或-O-;或其药学上适宜的酸盐。现已发现,IA和IB式的化合物对痕量胺相关受体(TAARs)具有良好的亲和力,特别是对TAAR1。这些化合物可用于治疗抑郁症、焦虑症、躁郁症、注意力缺陷多动障碍(ADHD)、与压力有关的疾病、如精神分裂症等精神疾病、帕金森病等神经系统疾病、阿尔茨海默病等神经退行性疾病、癫痫、偏头痛、高血压、物质滥用和代谢性疾病,如进食障碍、糖尿病、糖尿病并发症、肥胖症、血脂异常、能量消耗和吸收障碍、体温稳态障碍、睡眠和昼夜节律障碍以及心血管疾病。
