The present invention relates to compounds of Formula (I) wherein X is -S- or -NH-; R1 is alkyl, alkenyl, arylalkyl, arylalkenyl or aryl-O-alkyl, wherein the aryl groups are optionally substituted by one or more substituents, selected from the group consisting of lower alkyl, lower alkoxy, halogen or lower halogen-alkyl; R2 is hydrogen, lower alkyl or cycloalkyl; R3/R4 may form together with the N-atom to which they are attached a non aromatic5, 6 or 7 membered ring, which may contain in addition to the N-atom one additional heteroatom selected from the group consisting of O, S or N, and wherein the ring is optionally substituted by hydroxy, lower alkyl, lower alkoxy, -NR2, -CONR2, -CO-lower alkyl or benzyl; or may form together with the N-atom to which they are attached a heterocyclic ring system, containing at least two rings and which may contain one or two additional heretoatoms, selected from the group consisting of N or O; R is hydrogen or lower alkyl; R5 is hydrogen or lower alkyl; and to pharmaceutically suitable acid addition salts thereof. It has been found that the compounds are active on the GABAB receptor and therefore 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 or gastro-intestinal disorders.
本发明涉及公式(I)所示的化合物,其中X是-S-或-NH-;R1是烷基、烯基、芳烷基、芳烯基或芳基-O-烷基,其中芳基可被选自低烷基、低烷氧基、卤素或低卤代烷基的一个或多个取代基所取代;R2是氢、低烷基或环烷基;R3/R4可与它们所连接的N原子共同形成一个非芳香性的5、6或7元环,该环除了N原子外,还可包含一个选自O、S或N的附加杂原子,并且该环可被羟基、低烷基、低烷氧基、-NR2、-CONR2、-CO-低烷基或苄基所取代;或者可与它们所连接的N原子共同形成一个含有至少两个环的杂环体系,该体系可包含一个或两个选自N或O的附加杂原子;R是氢或低烷基;R5是氢或低烷基;以及涉及药用适宜的酸加成盐。已经发现,这些化合物对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、肌萎缩性侧索硬化症、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、创伤后应激障碍或胃肠功能紊乱。
