Description
技术领域
本发明涉及新的3,3-二取代的吲哚-2-酮衍生物、其制备方法、含有所述新的吲哚-2-酮衍生物的药物组合物和所述化合物治疗疾病的用途。
更具体的说,本发明涉及新的通式(I)的3,3-二取代的吲哚-2-酮衍生物,
其中
R1代表氢、卤素、具有1-7个碳原子的烷基或磺酰氨基;
R2代表氢或卤素;
R3表示氢、可选携带芳基取代的具有1-7个碳原子的烷基或者可选携带一个或两个卤素取代基的芳基;
R4代表具有1-7个碳原子的烷基;
R5代表通式(IIa)或(IIb)基团,
其中Q和W各自代表氮或CH;
R6、R7和R8各自代表氢、卤素、三氟甲基、具有1-7个碳原子的烷基或烷氧基,或者
R6和R7一起代表亚乙二氧基;

n是0、1或2;
及其药学上可接受的酸加成盐。
背景技术
美国专利No.4,452,808公开了具有选择性D2受体活性的4-氨基烷基-吲哚-2-酮衍生物。这些化合物能够用于治疗高血压。由该专利所提供的化合物之一、即4-[2-(二-N-丙基氨基)乙基]-2(3H)-吲哚酮用于治疗帕金森氏病。
欧洲专利No.281,309提供了在5位携带芳基哌嗪基-烷基取代基的吲哚-2-酮衍生物,它们能够用于治疗精神病症。在该专利中所描述的化合物之一、即5-[2-[4-(1,2-苯并异噻唑-3-基)-1-哌嗪基]-乙基]-6-氯-1,3-二氢-2H-吲哚-2-酮借助与D2、5-HT1A和5-HT2受体的相互作用发挥其活性,在临床治疗中用作抗精神病剂。
欧洲专利No.376,607公开了在3位被烷基哌嗪基-芳基取代的吲哚-2-酮衍生物,它们对5-HT1A受体发挥它们的活性,可用于治疗中枢神经障碍。
在国际专利申请WO 98/008816中,公开了在3位含有取代的烷基哌嗪基、取代的烷基哌啶基或烷基-环己基的吲哚-2-酮衍生物。这些化合物具备抗精神病活性。
二十世纪技术-社会发展的加速迫使人一直去适应,在不利的情况下可能引起适应性障碍的发生。适应性障碍构成精神或身心起源的疾病发展中的重要危险因素,例如焦虑综合征、精神紧张性障碍、抑郁、精神分裂症、感觉器官障碍、胃肠疾病、心血管疾病、肾障碍。
就上述临床模式的治疗而言,最普遍应用的药物对苯并二氮杂系统(例如地西泮)或中枢5-HT1A受体(例如丁螺酮、齐拉西酮)发挥它们的活性。在心身疾病的情况下,抗焦虑疗法经常补充给予具备抗高血压(作用于α1或α2受体)或抗溃疡(H1-受体拮抗剂)活性的药物。
不过,苯并二氮杂类型的抗焦虑剂伴有若干令人不快的副作用。它们具有强大的镇静活性,导致集中与记忆能力的衰退,并且具备肌肉松弛作用。所述副作用不利地影响患者的生活质量,限制了这类药物的应用范围。
不过,迄今已经在疗法中应用的作用于5-HT1A受体的药物伴有若干缺点和不需要的副作用。抗焦虑作用仅在治疗持续至少10-14天之后才能达到,这是一个缺点。此外,在最初的给药后发生焦虑产生作用。至于副作用,经常观察到瞌睡、困倦、眩晕、幻觉、头痛、认知障碍或恶心的发生。药物的这类作用使医师与患者之间的配合更加困难得多,因为患者相信症状的恶化是药物给药的后果。
除了发生在环境适应期间的精神紧张以外,另一重大的现代社会问题是人口的迅速老化。由于现代医药科学的结果,预期寿命得以延长,由于衰老而发生或者在衰退年龄中形成的疾病、特别是精神疾病的数量已呈跳跃式增长。阿尔茨海默氏病、血管性痴呆和老年性痴呆的治疗方案已经成为社会问题。
老化过程的另一后果是听力紊乱数量的明显增加。根据WHO的统计,在2001年,两亿五千万人患有中度或严重的听力功能障碍。在45-55岁和65-75岁人口中分别证实有10%和25%的老年性听力紊乱。
鉴于所列举的过程,对于新的和有效的药物存在迫切需求,以确保比当前更加有效地治疗这些疾病。
发明内容
本发明的目标是开发避免与5-HT1A受体结合的活性成分的上述缺点和不需要的副作用特征、与此同时能够用于治疗中枢神经系统障碍的药物成分。
本发明基于如下认识,即,通式(I)的3,3-二烷基取代的吲哚-2-酮衍生物具备显著的抗焦虑作用,但是令人意外的——与相似结构的现有技术化合物相反——不与5-HT1A受体结合。作为有利的结果,根据本发明的化合物没有与所述受体结合的化合物的副作用特征。此外,已经令人意外地发现,根据本发明的通式(I)化合物也与5-HT2C和α1受体结合,引起多巴胺释放,这些活性明显拓宽治疗应用的范围。

从欧洲专利说明书No.376,607和技术文献已知(A.Dekeyne,J.M.Rivet,A.Gobert,M.J.Millan:Neuropharmacology 40(7)p.899-910(2001);J.S:Sprouse et al.:Neuropsycho-pharmacology21(5)p.622-631(1999);A.Newman-Tancredi et al.:Eur.J.Pharmacol.355(2-3)pp.245-246(1998)),1,3-二氢-2H-吲哚-2-酮类型的现有技术化合物选择性地与5-HT1A受体结合,因而影响中枢神经系统。因此,它们能够用于治疗焦虑症、抑郁,此外还有心血管、胃肠和肾障碍。
本发明基于如下令人意外的认识,即,通式(I)的3,3-二烷基吲哚-2-酮衍生物具备抗焦虑活性,但是不与5-HT1A受体结合。这是为什么可以预期根据本发明的化合物没有与5-HT1A受体结合的活性成分的上述不良副作用特征。另一令人意外的认识是通式(I)化合物除了它们因与5-HT2C受体结合而带来的抗焦虑活性以外,还影响耳中的多巴胺释放,也与α1受体结合。
使用体重120-200g的雄性Wistar大鼠的脑区域制备物测定受体结合——5-HT2C受体结合除外。就5-HT1A受体结合的准备而言,使用额皮质制备物。从所分离的额皮质制备物进行α1受体结合研究。就5-HT2C受体结合实验而言,使用猪的脉络丛。借助Lowry(1951)的方法测定膜制备物的蛋白质含量。
按照Peroutka的方法测量5-HT1A受体结合(Peroutka,S.J.:J.Neurochem.47,p.529(1986))。配体是氚代8-羟基-N,N-二丙基-2-氨基四氢化萘(8-OH-DPAT)。就非特异性结合的测定而言,应用10μM血清素。温育血液体积为250μl。在25℃的温度下进行温育30分钟。加入9ml冰冷的50mM TRIS-HCl(pH7.7)缓冲液使反应终止,利用Whatman GFIB玻璃纤维滤纸快速真空过滤。借助液体闪烁分光光度法测量滤纸的放射性。
在5-HT2C和α1受体结合实验的过程中,配体分别是3H-mesulergin(1.0nM)和3H-哌唑嗪(0.3nM)。非特异性结合配体分别是米安色林(1μM)和哌唑嗪(1μM)。
IC50值是在测定浓度的特异性配体的存在下完全结合与非特异性结合之差为50%的浓度值。IC50值小于100纳摩尔的化合物被视为在本试验中是有效的。表1至3给出结果。

按照Vogel氏饮水冲突试验和抬升加迷路试验研究根据本发明的化合物对大鼠的抗焦虑作用(S.Pelow,P.Chopin,S.E.File,J.Briley:Neurosci.Methods 14,p.149(1985))。
Vogel氏饮水冲突试验

实验使用体重200-220g的雄性Sprague-Dawley大鼠。在处置后60min将动物置于设备的中心区域,观察下列四种参数达5min:
在开放臂中停留的时间(秒,sec);
在封闭臂中停留的时间(sec);
进入开放臂中的次数;

从上表数据可以看到,通式(I)化合物具备显著的抗焦虑作用。
按照Gáborján等人的方法在体重145-375g的豚鼠(Toxicoop,Hungary)中进行对听力减退和耳鸣的作用的研究(Gábor ján,A.,Lendvai,B,Vizi,E.S.:Neuroscience 90,p.131(1999))。利用高效液相色谱(HPLC)测量来自耳蜗制备物(外侧橄榄耳蜗输出管)的样品中的内耳多巴胺释放,作为听力减退的相关指标。在60分钟期间每3分钟收集一次样品(20个级份)。一般在第3和第13个级份期间施加电场刺激(S1,S2,2Hz,360shocks,60V;Grass MedicalInstruments)。在分别的实验中,通过灌注用100%N2饱和并且含有蔗糖而不是葡萄糖的缓冲液,模拟局部缺血(氧和葡萄糖丧失,OGD)。结果以每级份中多巴胺释放百分比表示。借助方差分析进行统计学分析(ANOVA),继之以Tukey检验。
从所得结果显示实施例76化合物对豚鼠内耳多巴胺释放的作用(图1)。初始刺激(SI)引发明显的多巴胺释放。这种释放在氧和葡萄糖丧失后的第二刺激之后减少了,但是在实施例76化合物的存在下,释放稳定化在显著高于没有氧和葡萄糖丧失时的水平。这种作用可以被解释为听力减退的抑制。
在由双侧颈动脉闭合诱导的全脑缺血模型中证明根据本发明的化合物的神经保护作用。使用体重60-90g的雄性蒙古沙土鼠作为试验动物。在手术后45min腹膜内给予供试化合物,剂量为30mg/kg。供试物质是悬浮在0.4%甲基纤维素溶液中的。在二乙醚麻醉下,通过前中线颈部切开暴露出左右颈总动脉,分离迷走神经和周围组织。拧紧动脉瘤夹达3min,实现颈动脉血流的完全停止。在手术期间,借助加热垫和加热灯使动物的体温保持在各自的手术前水平(37.5±0.5℃)。
手术后4天,将动物用60mg/kg i.p.戊巴比妥(10ml/kg)麻醉,向心脏先灌注盐水,再灌注固定溶液达30min,固定溶液为含有0.1%戊二醛、4%低聚甲醛与0.2%苦味酸的0.1M磷酸盐缓冲液(pH7.4)。从头颅中取出脑,在4℃相同固定溶液中后期固定至少1周。
借助切片机从不同水平的背海马切取6 0μm厚的交互冠状切片。将切片反复在0.1M磷酸盐缓冲液(pH7.4)中洗涤,借助银浸渍法染色。将切片在预备溶液(2%氢氧化钠和0.875%氢氧化铵溶液)中贮存5分钟两次,在0.875%氢氧化铵和0.5%硝酸银溶液中浸渍10分钟,置于洗涤溶液(0.5%碳酸钠与0.01%硝酸铵的29.1%乙醇水溶液)中2分钟两次,1分钟一次。然后将切片在含有1.5%甲醛和0.01%硝酸铵的9.9%乙醇溶液中显色,在0.5%乙酸溶液中固定3分钟三次。将已染色的切片置于0.1M磷酸盐缓冲液(pH7.4)和铬胶中,涂在平板上,脱水,用二甲苯处理。将盖板用DPX蓝(Fluka)固定。
在光学显微镜下检查切片,在6点规模上评价两侧海马CA1子域中的总体神经元损伤:(0)未损伤,(1)-0-10%;(2)-10-30%;(3)-30-50%;(4)-50-70%;(5)-70-90%;(6)90-100%细胞损失。借助Mann-Whitney U-检验对药物处理组与赋形剂处理组之间的组间差异进行统计学分析。结果总结在表6中。

上述实验的结果证明,根据本发明的化合物显著减少从全脑缺血恢复的动物海马CA1区中的细胞死亡。这些结果证实,供试化合物具备显著的神经保护活性。
在上述实验的基础上,根据本发明的新化合物可以证实有效治疗某些中枢神经系统和心血管系统障碍。这类中枢神经系统障碍包括不同形式的焦虑(泛化性焦虑疾病)、强迫症、惊恐性疾病、创伤后精神紧张性障碍、社会恐怖、抑郁、精神衰退继之以脑细胞死亡(例如阿尔茨海默氏病、中风、痴呆)。此外,根据本发明的化合物适合于治疗心血管疾病,特别是高血压。根据本发明的化合物的其他作用包括作为医药疗法副作用发生的听力减退和耳鸣。
令人意外地,与具有相似结构的现有技术化合物相反,根据本发明的化合物不作用于5-HT1A受体。它们明显地与5-HT2C受体结合,这显示了在焦虑的病理中发挥作用。根据本发明的化合物的α1受体作用提示了它们能够用于治疗心血管疾病。豚鼠内耳中的多巴胺释放引发活性表明它们可用于治疗听力减退和耳鸣。
