Description
本发明涉及式I的化合物
其中

Ar是苯基、苄基、萘基或杂芳基,所述杂芳基选自由以下各项组成的组:吡啶基、吡唑基、嘧啶基、异唑基或吡嗪基,其中Ar可以任选地被一个、两个或三个R1取代;

或涉及其药学上适用的酸加成盐,所有外消旋混合物,所有它们相应的对映体和/或光学异构体。
现在发现式I化合物对痕量胺相关受体(trace amine associated receptors,TAAR),尤其是TAAR1具有良好的亲和性。
所述化合物可以用于以下疾病的治疗:抑郁症(depression)、焦虑症(anxietydisorders)、双相性精神障碍(bipolar disorder)、注意缺陷多动障碍(attentiondeficit hyperactivity disorder)(ADHD)、应激相关障碍(stress-related disorders)、精神病性精神障碍(psychotic disorders)如精神分裂症(schizophrenia)、神经病(neurological diseases)如帕金森病(Parkinson’s disease)、神经变性疾病(neurodegenerative disorders)如阿尔茨海默病(Alzheimer’s disease)、癫痫(epilepsy)、偏头痛(migraine)、高血压(hypertension)、精神作用物质滥用(substanceabuse)和代谢性疾病(metabolic disorders)如进食障碍(eating disorders)、糖尿病(diabetes)、糖尿病并发症(diabetic complications)、肥胖症(obesity)、异常脂肪血症(dyslipidemia)、能量消耗和同化障碍(disorders of energy consumption andassimilation)、体温稳态紊乱和功能障碍(disorders and malfunction of bodytemperature homeostasis)、睡眠和昼夜节律障碍(disorders of sleep and circadianrhythm)、以及心血管疾病(cardiovascular disorders)。
对于可以结合至肾上腺素能受体的化合物报道的一些生理效应(即心血管效应、低血压、镇静诱导)(WO02/076950,WO97/12874或EP 0717 037)在旨在治疗如上所述的中枢神经系统疾病的药物的情况下可能被认为是不适宜的副作用。因此,适宜的是获得与肾上腺素能受体比较对于TAAR1受体具有选择性的药物。本发明的目标物对TAAR1受体显示超过肾上腺素能受体的选择性,尤其是与人类和大鼠α1和α2肾上腺素能受体比较的良好选择性。
经典的生物胺(血清素,去甲肾上腺素,肾上腺素,多巴胺,组胺)在中枢和外周神经系统中作为神经递质发挥重要的作用[1]。它们的合成和储存,以及它们在释放后的降解和再吸收被严格调节。已知生物胺水平的不平衡在很多病理情况下是造成改变的脑功能的原因[2-5]。第二类的内源胺化合物,即通常所说的痕量胺(TA)与经典的生物胺在结构、新陈代谢和亚细胞定位方面显著地重叠。TA包括对-酪胺、β-苯基乙胺、色胺和章鱼胺,并且它们在哺乳动物神经系统中以通常比经典的生物胺低的水平存在[6]。
它们的调节异常与多种精神病学疾病相关,如精神分裂症和抑郁症[7],以及其他病情如注意缺陷多动障碍、偏头痛、帕金森病、精神作用物质滥用和进食障碍[8,9]。
长期以来,TA特异性受体仅是基于人类和其他哺乳动物的CNS中解剖学上离散的高亲和性TA结合部位而猜测的[10,11]。因此,TA的药理学作用被认为是经由众所周知的经典生物胺的机制通过如下而介导的:或者通过引起它们的释放、抑制它们的再吸收或者通过与它们的受体体系“交叉反应”介导[9,12,13]。随着近来GPCR新家族的数个成员,即痕量胺相关受体(TAAR)的识别,该观点明显地改变[7,14]。在人类中存在9种TAAR基因(包括3种假基因)并且在小鼠中存在16种基因(包括1种假基因)。TAAR基因不含有内含子(有一个例外,TAAR2含有1个内含子)并且在相同的染色体节段上位于彼此相临的位置。受体基因的系统发育关系,与深入的GPCR药效团相似性比较和药理学数据一致,暗示这些受体形成三个不同的亚族[7,14]。TAAR1在人类与啮齿类之间高度保守的四种基因(TAAR1-4)的第一亚类中。TA经由Gα活化TAAR1。已显示TA的调节异常对多种疾病的病因学有贡献,所述多种疾病如抑郁症、精神病、注意缺陷多动障碍、精神作用物质滥用、帕金森病、偏头痛、进食障碍、代谢性疾病,并且因此TAAR1配体对于这些疾病的治疗具有很高的潜在可能。
因此,对于增加关于痕量胺相关受体的知识存在广泛的兴趣。

TAAR表达质粒和稳定转染的细胞系的构建
为了构建表达质粒,基本上如Lindemann等[14]所述,从基因组DNA扩增人类、大鼠和小鼠TAAR 1的编码序列。以1.5mM Mg2+使用延伸高保真PCR体系(Expand High FidelityPCR System)(Roche Diagnostics),并按照制造商的使用说明将纯化的PCR产物克隆至pCR2.1-TOPO克隆载体(Invitrogen)中。将PCR产物亚克隆至pIRESneo2载体(BD Clontech,Palo Alto,California)中,并且在引入细胞系中之前对表达载体进行序列证实。
基本上如Lindemann等(2005)所述,培养HEK293细胞(ATCC#CRL-1573)。为了产生稳定转染的细胞系,用含有TAAR编码序列的pIRESneo2表达质粒(上面描述)与Lipofectamine 2000(Invitrogen)根据制造商的使用说明转染HEK293细胞,并且转染后24小时,用1mg/ml G418(Sigma,Buchs,瑞士)补充培养基。在约10d的培养周期之后,将克隆分离、扩增并用cAMP Biotrak酶免疫测定(EIA)系统(Amersham),按照由制造商提供的非乙酰化EIA程序对其测定对痕量胺(所有化合物购自Sigma)的反应性。将对于15个传代的培养周期显示出稳定的EC50的单克隆细胞系用于所有随后的研究。
