    • 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 (CH 2 ) n , wherein n represents 1, 2 or 3 m is 0 or 1; X is NR, wherein R is H or (C 1-4 )alkyl; Q is H or (C 1-4 )alkyl; Ar 1 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; Ar 2 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; R 1 and R 2 independently represent hydrogen, optionally substituted amino, optionally substituted (C 1-6 )alkyl or optionally substituted phenyl; or a pharmaceutically acceptable salt thereof.
    • 本发明提供作为人食欲素受体的非肽拮抗剂的N-芳基乙酰基环胺衍生物,特别是食欲素-1受体。 特别地,这些化合物可用于治疗肥胖症,包括在2型(非胰岛素依赖性)糖尿病患者中观察到的肥胖症和/或睡眠障碍。 另外,这些化合物可用于治疗中风,特别是缺血性或出血性中风,和/或阻断催吐反应,即可用于治疗恶心和呕吐。 (I)其中:Y表示键,氧,NQ或基团(CH 2)n,其中n表示1,2或3m为0或1; X是NR,其中R是H或(C 1-4)烷基; Q是H或(C 1-4)烷基; Ar 1是芳基或含有至多4个选自N,O和S的杂原子的单或双环杂芳基; 任何一个可以任选地被取代; Ar 2表示任选取代的苯基,任选取代的含有至多4个选自N,O和S的杂原子的5-或6-元杂环基,或含有至多4个选自以下的杂原子的任选取代的双环芳族或双环杂芳族基团: N,O和S; R 1和R 2独立地表示氢,任选取代的氨基,任选取代的(C 1-6)烷基或任选取代的苯基; 或其药学上可接受的盐。
