背景技术
MCH,19—氨基酸环肽,是在十年前在硬骨鱼中首先发现的,该化合物似乎能够调节颜色变化。最近,MCH主要是在侧面视丘下部合成得到,是一种调节给食行为的脑中枢;由于其可作为动物进食行为的调节剂,它已变成人们的研究课题。人们已经公知,中枢服用MCH可以刺激进食且促进啮齿动物中的脂肪贮存。人们也知道,过分表达MCH的小鼠会肥胖。如Shimada等人报道(Nature,Vol.396(17 Dec.1998),pp.670—673),缺乏MCH的小鼠可降低体重,且由于饮食过少症(减少进食)会导致消瘦。基于他们的发现,作者建议MCH行为拮抗剂对治疗肥胖症有效。美国专利5,908,830公开了组合治疗糖尿病和肥胖症的方法,该方法涉及服用代谢率提高剂和进食行为改良剂,后者的实例为MCH拮抗剂。美国专利6,043,246公开了脲衍生物,该衍生物可用作神经肽Y受体拮抗剂和用作治疗代谢系统疾病(包括肥胖症和糖尿病)的试剂。出版的PCT专利申请WO 00/27845描述了一类以螺-二氢吲哚为特征的化合物,该化合物为选择性神经肽Y Y5拮抗剂,可用于治疗肥胖症及与此有关的并发症。一般地,2000年9月14日申请的序号为60/232,255的美国临时专利申请公开并要求保护芳基取代脲神经肽Y Y5拮抗剂及其在治疗肥胖症、饮食过多症(增加进食)和糖尿病中的用途。

除非另外定义,这里使用的所有技术和核科学术语具有本发明技术领域人员普通理解的相同含义。由此,如术语烷基(包括烷氧基的烷基部分)是指通过离去1至8个碳原子中的单个原子的直链或支链饱和烃衍生的一价基团,优选含1至6个碳原子;
芳基表示含6至14个碳原子且含至少一个苯环的碳环基团,碳环中的所有可能的可取代芳族碳原子都是可能的连接位置。优选的芳基包括苯基、1—萘基、2—萘基和茚满基,特别是苯基和取代苯基;

显示出良好的MCH受体调节活性的本发明有代表性化合物及其活性(以纳摩尔nM表示的KI值范围)列于表I中。
根据其结构,本发明化合物可以与有机或无机酸或有机或无机碱形成可药用盐。这类成盐的适宜酸的实例为盐酸、硫酸、磷酸、乙酸、柠檬酸、草酸、丙二酸、水杨酸、苹果酸、富马酸、琥珀酸、抗坏血酸、马来酸、甲磺酸及其它本领域技术人员公知的矿物酸和羧酸。对于与碱形成的盐,适宜的碱包括如NaOH、KOH、NH4OH、氢氧化四烷基铵等。
