发明领域
本发明涉及具有重要药理性质、特别是CNS活性和消炎作用的新的苯基-烷基-咪唑。本发明的化合物是H3受体拮抗剂。
发明背景
欧洲专利申请No.0 420 396 A2(Smith Kline & FrenchLaboratories Limited)和Howson等Bioorg.& Med.Chem.Letters,Vol.2 No.1(1992),pp.77-78记载了有脒基的咪唑衍生物作为H3激动剂。Van der Groot等(Eur.J Med.Chem.(1992)Vol.27,pp.511-517)记载了异硫脲组胺类似物作为有效的、组胺H3受体的激动剂或拮抗剂,这些异硫脲组胺类似物与上面引用的两个参考文献中的化合物部分重叠。Clapham等[“组胺H3受体拮抗剂改善认知和增加小鼠体内乙酰胆碱释放的能力,”,英国精神药理学协会1993年7月25-28日在J.Psychopharmacol.(Abstr.Book),A 17报道]记载了组胺H3受体拮抗剂改善认知和增加小鼠体内乙酰胆碱释放的能力。Clapham等[“选择性组胺H3受体拮抗剂硫代过酰胺改善短期记忆和逆转小鼠学习的能力,”Brit.J.Pharm.Suppl.,1993,110,Abstract 65P]记载的结果表明,硫代过酰胺能够改善短期记忆和逆转小鼠的学习能力,并暗示H3受体参与调节认知功能。Yokoyama等[“组胺H3受体拮抗剂硫代过酰胺对小鼠电诱导痉挛的作用,”Eur.J.Pharmacol.,vol.234(1993),pp.129-133]报道了硫代过酰胺是如何减少各阶段痉挛持续时间和提高电痉挛阈值的,并继续提出这些和其它发现支持中枢组胺能系统参与抑制发作的假说。国际专利出版物WO 9301812-Al(Smith Kline Beecham PLC)记载了S-[3-(4(5)-咪唑基)正丙基]异硫脲作为组胺H3受体拮抗剂的用途,特别是用于治疗认知紊乱,例如,阿耳茨海默氏病和年龄相关的记忆损害。Schlicker等[“新的组胺H3受体拮抗剂:H3受体结合实验的亲和力和对两种功能型H3受体模型的效力”]记载了若干个其中的咪唑基烷基与胍基、酯基、或酰胺基相连的咪唑基烷基化合物(包括硫代酰胺和脲),并将这些化合物与硫代过酰胺进行了比较。Leurs等[“组胺H3受体:开发新药的目标,”Progr.Drug Res.(1992)vol.39,pp.127-165]和Lipp等[“H3受体的药物化学,”参见The Histamine Receptor,eds.:Schwartz and Haas,Wiley-Liss,New York(1992),pp.57-72]对几种合成的H3受体拮抗剂进行评价,Lipp等(出处相同)定义了H3受体拮抗剂中必需的结构要求。
A选自-O-CO-NR1-、-O-CO-、-NR1-CO-NR1-、-NR1-CO-、-NR1-、-O-、-CO-NR1-、-CO-O-和-C(:NR1)-NR1-;
当式Ⅰ的分子中有两个或三个R1时,它们可以相同或不同,选自氢和低级烷基、芳基、环烷基、杂环和杂环烷基、和-(CH2)y-G,其中,G选自CO2R3、COR3、CONR3R4、OR3、SR3、NR3R4、杂芳基和苯基,其中苯基任选地被卤素、低级烷氧基或多卤低级烷基取代,Y为1-3的整数,
R2选自氢和卤原子,和烷基、链烯基、炔基和三氟甲基、和OR3、SR3和NR3R4,
R3和R4各独立地选自氢、和低级烷基和环烷基,或R3和R4与环中的氮原子一起形成含有4-6个碳原子的、可被一个或两个低级烷基取代的饱和环,
如果Y为1,G为OR3、SR3或NR3R4,则R3和R4都不是氢,
-(CH2)n-A-R1在3或4位,R2在任何游离位置,
m为1-3的整数,和
n为0或1-3的整数。
1996年8月16日提出的美国专利申请No.08/689951和1997年8月14日提出的美国专利申请No.08/909319公开了用至少一种组胺H1受体拮抗剂和至少一种组胺H3受体拮抗剂结合治疗过敏性鼻炎症状的组合物。
鉴于本领域对影响H3受体的化合物的兴趣,具有H3受体拮抗剂活性的新的化合物会是对本领域的可喜的贡献。本发明正是通过提供具有H3拮抗剂活性的、新的化合物做出了这一贡献。

本发明进一步的特征是含有如上定义的式Ⅰ化合物(或盐、或溶剂化物或互变异构体)作为活性成分与药用载体或赋形剂的药物组合物。
本发明进一步的特征是治疗下列疾病的方法:炎症、过敏、胃肠道疾病、心血管病或中枢神经系统紊乱,该方法包括给患有相应疾病的病人(即需要此种治疗的患者)服以有效量的、如上定义的式Ⅰ化合物(或其盐、或其溶剂化物、或其互变异构体)。例如,本发明的一个特征是治疗下列疾病的方法:过敏、炎症、低血压、青光眼、睡眠失调、胃肠道蠕动过快和过慢、中枢神经系统活性过低和过高、阿耳茨海默氏病、精神分裂症、肥胖和偏头痛,该方法包括给需要此种治疗的病人服用有效量的式Ⅰ化合物(或其盐、或其溶剂化物或其互变异构体)。

本发明也包括用与组胺H1受体拮抗剂结合的式Ⅰ化合物治疗过敏反应诱导的呼吸道(即上呼吸道)反应。发明详述
由于咪唑环,式Ⅰ化合物能够以互变异构体形式存在:N-氢原子可从一个氮原子互变到环上的另一个氮原子上。当q为1和Y为取代烷基时,或当各(Z)n上的一个R1取代基不是氢时,式Ⅰ化合物将有一个不对称碳原子,由于这一手性中心,式Ⅰ化合物将以不同形式存在。包括对映体和非对映体在内的所有这些异构体都包括在本发明中。
本发明的化合物是碱,与无机酸和有机酸形成可药用的盐。形成这些盐的适宜的酸的例子为盐酸、硫酸、磷酸、醋酸、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、甲磺酸和本领域普通技术人员已知的其它矿物酸和羧酸。盐的制备是通过将游离碱和足够量的所需酸按常规方法进行反应。将盐用适宜的稀碱水溶液例如,稀氢氧化钠水溶液、稀碳酸钾水溶液、稀氨水和稀碳酸氢钠水溶液进行处理使之再生成游离碱形式。游离碱与相应的盐的区别在于某些物理性质,例如在极性溶剂中的溶解度,但用于本发明的目的时,盐同样等同于其相应的碱。
式Ⅰ化合物可以以非溶剂化以及溶剂化形式存在,包括水合物形式,例如半水合物。通常,用于本发明的目的时,与可药用的溶剂例如水、乙醇等形成的溶剂化形式等同于非溶剂化形式。
已知许多化合物具有组胺H1受体拮抗剂活性。许多有用的化合物可被分成乙醇胺类、乙二胺类、烷基胺类、吩噻嗪类或哌啶类。典型的H1受体拮抗剂包括但不限于以下:苄苯哌咪唑、哌吡庚啶、苄酞嗪、acrivastine、溴抗感明、西替立嗪、右扑尔敏、氯苯苄咯、赛克利嗪、carebastine、赛庚啶、氯苯吡醇胺、descarboethoxyloratadine(也叫做SCH-34117)、苯海拉明、苯吡甲醇胺、二甲吡茚、ebastine、epinastine、efletirizine、fexofenadine、羟嗪、甲哌噻庚酮、氯雷他定、左卡巴斯汀、mizolastine、甲奎吩嗪、甲苯吡、noberastine、氯苯甲嗪、norastemizole、苄哌香豆素、甲氧苄二胺、异丙嗪、丁苯哌丁醇、吡苄明、替美司丁、异丁嗪、吡咯吡胺。也可用已知方法包括离体豚鼠回肠的组胺收缩应答的特异性阻断毫无困难地评价以决定其它化合物对H1受体的活性。例如,参见1998年2月19日出版的WO98/06394。
例如,本发明的H3拮抗剂能与选自以下的H1拮抗剂结合:苄苯哌咪唑、哌吡庚啶、苄酞嗪、溴抗感明、西替立嗪、右扑尔敏、氯苯苄咯、carebastine、descarboethoxyloratadine(也叫做SCH-34117)、苯海拉明、苯吡甲醇胺、ebastine、fexofenadine、氯雷他定、左卡巴斯汀、mizolastine、norastemizole或丁苯哌丁醇。
例如,本发明的H3拮抗剂也可与选自以下的H1拮抗剂结合:哌吡庚啶、溴抗感明、西替立嗪、右扑尔敏、carebastine、descarboethoxyloratadine(也叫做SCH-34117)、苯海拉明、ebastine、fexofenadine、氯雷他定或norastemizole。
典型的结合包括:本发明的H3拮抗剂与氯雷他定、本发明的H3拮抗剂与descarboethoxyloratadine、本发明的H3拮抗剂与fexofenadine以及本发明的H3拮抗剂与西替立嗪。
