are as defined herein and to pharmaceutically suitable acid addition salts thereof.
It has been found that the compounds of the invention are active on the GABA
B
receptor and therefore are useful for the treatment of anxiety, depression, epilepsy, schizophrenia, cognitive disorders, spasticity and skeletal muscle rigidity, spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, cerebral palsy, neuropathic pain and craving associated with cocaine and nicotine, psychosis, panic disorder, posttraumatic stress disorders and gastro-intestinal disorders.
本发明涉及具有以下公式的化合物：其中X是-S-或-NH-；R3/R4与它们所连接的N原子一起形成一个非芳香性的5、6或7元环，该环除了N原子外，还可以选择性地包含一个额外的杂原子，该杂原子选自O、S和N的组中，并且环可以选择性地被羟基、低级烷基、低级烷氧基、-NR2、-CONR2、-CO-低级烷基或苄基取代；或者R3/R4与它们所连接的N原子一起形成一个含有两个或三个环的杂环体系，该体系可以选择性地包含一个或两个额外的杂原子，这些杂原子选自N和O的组中，并且含有的碳原子数不超过20个；以及R、R1、R2和R5如本文所述，以及药用适当的酸加成盐。已经发现，本发明的化合物对GABAB受体具有活性，因此可用于治疗焦虑、抑郁、癫痫、精神分裂症、认知障碍、痉挛和骨骼肌僵直、脊髓损伤、多发性硬化症、肌萎缩侧索硬化症、脑瘫、神经性疼痛以及与可卡因和尼古丁相关的渴望、精神疾病、恐慌症、创伤后应激障碍和胃肠功能障碍。
