The present invention relates to compounds of formulae IA and IB
wherein
R
1
and R
2
are each independently lower alkyl or —(CH
2
)
m
—O-lower alkyl, or together with the N atom to which they are attached form a heterocyclic ring;
R
3
is hydrogen or lower alkyl;
R
4
is lower alkyl; hetaryl is 3H-imidazole-2,4-diyl or 1H-pyrazole-1,4-diyl; n is 1 or 2; and m is 1 or 2; and to pharmaceutically acceptable acid addition salts thereof. These compounds may be used for the treatment of Alzheimer's disease, Parkinson's disease, Huntington's disease, neuroprotection, schizophrenia, anxiety, pain, respiration deficits, depression, ADHD, drug addiction, such as amphetamine, cocaine, opioids, ethanol, nicotine, cannabinoids, or for the treatment of asthma, allergic responses, hypoxia, ischaemia, seizure and substance abuse, or for use as sedatives, muscle relaxants, antipsychotics, antiepileptics, anticonvulsants and cardiaprotective agents for coronary artery disease and heart failure.
本发明涉及式IA和IB的化合物,其中R1和R2分别独立地是较低的烷基或-(CH2)m-O-较低的烷基,或者与它们连接的N原子一起形成一个杂环环;R3是氢或较低的烷基;R4是较低的烷基;hetaryl是3H-咪唑-2,4-二基或1H-吡唑-1,4-二基;n为1或2;m为1或2;以及其药学上可接受的酸盐。这些化合物可用于治疗阿尔茨海默氏病、帕金森氏病、亨廷顿氏病、神经保护、精神分裂症、焦虑、疼痛、呼吸功能障碍、抑郁症、注意力缺陷多动障碍、药物成瘾(如安非他明、可卡因、阿片类药物、乙醇、尼古丁、大麻素等)的治疗,或用于哮喘、过敏反应、缺氧、缺血、癫痫和物质滥用的治疗,或作为镇静剂、肌肉松弛剂、抗精神病药、抗癫痫药、抗惊厥药和对冠心病和心力衰竭的心脏保护剂。
