The present invention provides N-aryl acetyl cyclic amine derivatives which are non-peptide antagonists of human orexin receptors, in particular orexin-1 receptors. In particular, theses compounds are of potential use in the treatment of obesity, including obesity observed in Type 2 (non-insulin-dependent) diabetes patients, and/or sleep disorders. Additionally these compounds are useful in the treatment of stroke, particularly ischemic or haemorrhagic stroke, and/or blocking the emetic response, i.e. useful in the treatment of nausea and vomiting. (I) wherein: Y represents a bond, oxygen, NQ or a group (CH2)n, wherein n represents 1, 2 or 3 m is 0 or 1; X is NR, wherein R is H or (C1-4)alkyl; Q is H or (C1-4)alkyl; Ar1 is aryl, or a mono or bicyclic heteroaryl group containing up to 4 heteroatoms selected from N, O and S; any of which may be optionally substituted; Ar2 represents optionally substituted phenyl, an optionally substituted 5- or 6- membered heterocyclyl group containing up to 4 heteroatoms selected from N, O and S, or an optionally substituted bicyclic aromatic or bicyclic heteroaromatic group containing up to 4 heteroatoms selected from N, O and S; R1 and R2 independently represent hydrogen, optionally substituted amino, optionally substituted (C1-6)alkyl or optionally substituted phenyl; or a pharmaceutically acceptable salt thereof.
本发明提供了N-芳基乙酰环氨基衍生物,其为人类俄雷克星受体的非肽拮抗剂,特别是俄雷克星-1受体的拮抗剂。具体而言,这些化合物可能用于治疗肥胖症,包括2型(非胰岛素依赖性)糖尿病患者观察到的肥胖症,和/或睡眠障碍。此外,这些化合物在中风治疗中也很有用,特别是缺血性或出血性中风,和/或阻断呕吐反应,即在恶心和呕吐治疗中很有用。其中:Y代表键,氧,NQ或(CH2)n基团,其中n代表1、2或3,m为0或1;X为NR,其中R为H或(C1-4)烷基;Q为H或(C1-4)烷基;Ar1为芳基,或含有最多4个异原子(N、O和S)的单环或双环杂芳基团;任何一个可能是可选择取代的;Ar2代表可选择取代的苯基,一个可选择取代的含有最多4个异原子(N、O和S)的5-或6-成员杂环基团,或一个可选择取代的双环芳香或双环杂芳基团,其中最多含有4个异原子(N、O和S);R1和R2独立地代表氢,可选择取代的氨基,可选择取代的(C1-6)烷基或可选择取代的苯基;或其药用盐。
