Abstract
本发明提供一种用式I化合物治疗阿尔茨海默病的方法:本发明还提供一种用式I化合物抑制淀粉样蛋白聚集的方法和一种将淀粉样沉积物成象的方法以及新颖的式I化合物。
Description
发明领域
本发明涉及抑制淀粉样的蛋白聚集和使淀粉样沉积物成象的方法。更具体地说,本发明涉及抑制淀粉样蛋白聚集以治疗阿尔茨海默病。
发明背景
淀粉样变性是一种以各种不溶性原纤蛋白在患者组织中积聚为特征的疾病。包含积聚物或沉积物的原纤蛋白被称作淀粉样蛋白。虽然沉积物中发现的具体蛋白或肽有所不同,但原纤形态学和大量β-片状二级结构则是许多类型的淀粉样变性所共同存在的。淀粉样沉积物通过淀粉样蛋白的聚集、然后通过聚集物和/或淀粉样蛋白的进一步结合而形成。
多种疾病已显示有淀粉样沉积物的存在,它们有其特定的关联蛋白,这些疾病例如有布氏杆菌病、Muckle-Wells氏综合征、自发性淀粉样变性、淀粉样多神经病、淀粉样心肌病、全身性老年性淀粉样变性、具有淀粉样变性的遗传性小脑出血、阿尔茨海默病、唐氏先天愚征、绵羊疯痒病、痉挛性假硬化症、苦鲁病、Gerstmann-Straussler-Scheinker氏综合征、甲状腺髓样癌,透析患者中的单独心房淀粉样蛋白、β2-微球蛋白淀粉样蛋白,包涵体肌炎、肌肉消耗性疾病中的β2-淀粉样沉积物、镰形细胞贫血、帕金森氏病和胰岛糖尿病II型胰岛瘤。
阿尔茨海默病是一种退化性大脑病症,其临床特征是,记忆、认知、推理、判断和情绪稳定性的进行性丧失,逐渐导致精神衰退,最终死亡。由于阿尔茨海默病和相关的退化性大脑病症是日益老化的人口的主要医学问题,因此,需要新的疾病的诊断和治疗方法。
人们一直努力寻求一种简便的非损伤性的对患者的淀粉样沉积物进行检测和定量的方法。目前,对淀粉样沉积物的检测包括活组织检查或尸体解剖材料的组织学分析。二种方法都有重大缺陷。例如,尸体解剖只能用于死后诊断。
将体内淀粉样沉积物直接成象很困难,因为沉积物与正常的组织有许多相同的物理特性,即,密度和含水量。以往的直接用磁共振(MRI)和计算机辅助段层摄影法(CAT)将淀粉样沉积物成象的尝试令人失望,只能在某些顺利条件下检测出淀粉样沉积物。此外,用抗体、血清淀粉样淀粉样P蛋白或其它探测分子将淀粉样沉积物标记的努力在组织周边方面提供了一些选择性,但对组织内部的成象性差。
因此,一种非损伤性的对患者的淀粉样沉积物进行成象和定量的方法将是有用的。此外,可抑制淀粉样蛋白聚集成淀粉样沉积物的化合物将是有用的。

将标记化合物给药于患者可采用全身或局部给药途径。例如,标记化合物可以以传输于患者全身的方式给药。也可将标记化合物施药于特定器官或感兴趣的组织。例如,宜将脑中的淀粉样沉积物定位和定量,以诊断或追踪患者阿尔茨海默病的进展。
“组织”一词是指患者身体的一部分。组织的例子包括脑、心、肝、血管和动脉。可检测量是用所选检测方法检测出来而所需的标记化合物的量。导入患者中以供检测的标记化合物的量可容易地由本领域的技术人员确定。例如,将给予患者的标记化合物的量增加至该化合物可用所选检测方法检测出来。在化合物中导入标记以检测化合物。
“患者”一词是指人和其它动物。本领域的技术人员还精通于确定足以使化合物与淀粉样沉积物结合的时间。所需时间可容易地通过将可检测量的式I标记化合物导入患者然后在施药后的不同时间检测标记化合物而加以确定。

本领域的技术人员熟悉各种检测标记化合物的方法。例如,磁共振成象法(MRI)、正电子发射段层摄影法(PET)或单光子发射计算段层摄影法(SPECT)可用来检测放射性标记的化合物。导入化合物的标记将取决于所需的检测方法。例如,若选择PET作为检测方法,则化合物必须具有正电子发射原子,如11C或18F。
式I化合物中的合适标记的另一个例子是可用磁共振成象法(MRI)(该方法有时也称核磁共振法(NMR))检测的原子,如13C、15N或19F等。此外,式I标记化合物也可用使用顺磁对比剂的MRI检测。
另一个检测方法的例子是电子顺磁共振法(EPR)。在该情况下,可使用本领域公知的EPR探头,如硝基氧。
淀粉样沉积物的成象也可定量进行,这样,可确定淀粉样沉积物的量。
本发明还提供通过施药于需要抑制淀粉样蛋白聚集的患者以淀粉样蛋白抑制量的式I化合物来抑制淀粉样蛋白聚集成淀粉样沉积物的方法。本领域的技术人员只需增加施药于患者的式I化合物量至淀粉样沉积物的生长减少或停止,就可容易地确定淀粉样蛋白抑制量。生长率可用成象法或通过采取患者的组织检样并观察其中的淀粉样沉积物而加以评估。
需要抑制淀粉样蛋白聚集的患者是患有淀粉样蛋白聚集的疾病或病症的患者。这些疾病和病症的例子包括布氏杆菌病、Muckle-Wells氏综合征、自发性淀粉样变性、淀粉样多神经病、淀粉样心肌病、全身性老年性淀粉样变性、具有淀粉样变性的遗传性小脑出血、阿尔茨海默病、唐氏先天愚征、绵羊疯痒病、痉挛性假硬化症、苦鲁病、Gerstmann-Straussler-Scheinker氏综合征、甲状腺髓样癌,透析患者中的单独心房淀粉样蛋白、β2-微球蛋白淀粉样蛋白,包涵体肌炎、肌肉消耗性疾病中的β2-淀粉样沉积物和胰岛糖尿病II型胰岛瘤。
本发明还提供化合物中的一个或多个原子已被放射性同位素置换的式I化合物(标记化合物)。放射性同位素可以是任何同位素。但优选3H、123I、125I、131I、11C和18F。本领域的技术人员熟悉将放射性同位素导入化合物的方法。例如,容易制得其中的一个碳原子为11C或14C的式I化合物。
本发明的化合物可以每日约0.1-1000mg的剂量施药于患者。对于体重约为70kg的普通成人,约0.01-100mg/kg体重/日的剂量就足够了。但所用具体剂量可进行变化。例如,剂量可取决于许多因素,包括患者的要求、需治疗的病症的严重性、所用化合物的药理活性。对于特定患者的最佳剂量的确定是本领域的技术人员公知的。
下面的实施例是用来举例说明本发明的具体实施方式,而绝非是用来限定包括权利要求书在内的申请文件的范围。
实施例合成
式I化合物可用流程图6-9所示的几个途径制备。流程图1-5显示可用来得到所需起始胺(IV)、(VIII)、(XV)和(XXI)的合成途径。
在流程图1中,合适取代的醛(I)和硝基苯乙酸(II)在150℃于哌啶中加热时产生烯烃(III)。标准的氢化条件(如阮内镍)给出所需胺(IV)。
流程图2描述了含有三个亚甲基系链的胺(VIII)的合成。醛(I)与硝基酮(V)在氢氧化钠的存在下的缩合给出所需的α,β-不饱和酮,而该酮在标准氢化条件下(阮内镍)给出(VII),然后在Wolff-Kishner条件下给出所需胺(VIII)。
流程图3与流程图2非常类似,所不同的是,醛(I)与取代的苯胺(IX)缩合。
流程图4示出标准的Wittig条件,在该条件中,起始物质(XII)和(XIII)分别通过醛醇缩合和内鎓盐化学而得到。醛(XII)与溴正膦(XIII)在碱(如丁基锂)的存在下反应,给出二烯(XIV)。(XIV)的标准还原条件(例如,阮内镍)给出所需胺(XV)。
流程图5示出含有5-亚甲基系链的胺(XXI)的合成。溴正膦(XVII)〔由相应的取代的溴化物(XVI)形成〕与硝基醛(XIX)〔由相应的醇(XVIII)的Swern氧化而得到〕在碱(如LHDMS)存在下的Wittig反应产生烯烃(XX)。用标准条件(阮内镍)还原(XX),给出胺(XXI)。
流程图6示出一条得到式I化合物的途径。通过Buchwald偶合(方法A)和其后的皂化或通过使用Ullman反应(方法B),可从(IV)、(VIII)和(XV)等胺中分离出式I化合物。含羟基的式I化合物(如实施例4和6)需要在合成的最后步骤中用试剂(如三溴化硼)将羟基保护基去甲基化。
当存在反应性官能团(如氨基和羧酸)时也要使用保护基,以避免不希望的副反应。通常将羧基转化成酯(如,叔丁基、苄基),一般将氨基酰化(如乙酰基或三甲基硅基)。这些和其它的此类保护基是有机化学家周知的,在Greene和Wuts编著,有机合成中的保护基(Protective Groups in Organic Synthesis),纽约John Wiley and Sons出版(1991年第2版)中有详尽的描述。所有引文纳入于此作为参考。
流程图7示出通过(IV)、(VIII)和(XXI)等胺与氟-硝基中间体(XXIV)在碱(如LHMDS或三乙胺)的存在下反应产生酯(XXV)来合成式I化合物。然后可用标准条件(如氢氧化钠)将该酯皂化。
在流程图8中,可将胺(XV)与可容易得到的氟取代的羧酸〔如(XXVI)或(XXVII)〕在各种碱(如DBU或三乙胺)的存在下偶合,生成式I化合物。
流程图9描述了胺(VIII)与容易得到的甲酯(XXVIII)在碱(如咪唑)的存在下偶合,生成酯(XXIX)。然后可将该酯用常法皂化,生成式I化合物。
流程图10示出含氟中间体(XXIV)的合成,它通过将容易得到的甲酯(XXX)硝化成(XXVIII)而得到。用氰化钾处理(XXVIII),生成(XXIV)。
在流程图11中,示出与实施例18相关的化合物的合成。邻位取代的苯甲酸(XXVI)的钾盐与取代的苯胺(XXVII)在碳酸钾和乙酸铜的存在下反应,产生各种碘取代的氨基苯甲酸(XXVIII)。(XXVIII)与取代的硼酸和氯化钯的反应产生所需的取代的氨基苯甲酸(XXX)。
当然,应认识到,本发明的若干式I化合物可用标准的有机反应(如氧化、还原、烷基化、缩合、消去和类似的公知合成方法)由式I定义的其它化合物制得。例如,可容易地将Ra表示氢的式I化合物烷基化,形成Ra表示C1-C6烷基的化合物。R1表示NH2的化合物可容易地通过与酰基卤或酸酐反应而酰化,形成R1表示-NHCORb的化合物。类似地,可容易地将R1表示NO2的化合物还原,形成R1表示NH2的化合物。苯甲酸(其中,R8表示COOH)可用常规方法容易地转化成酯、酰胺、盐和其它前药。例如,可将苯甲酸与草酰氯反应,形成酰基氯,然后,可容易地将该酰基氯与磺酰胺(如甲磺酰胺)反应,产生相应的R8表示-CONHSO2CH3的本发明的化合物。胺的形成流程图1流程图2流程图3流程图4流程图5偶合途径流程图6流程图7R是形成酯的基团,如烷基或苄基。流程图8流程图9含氟中间体的形成流程图10流程图11

具体值之后的括号内的字母表示受试化合物的具体的合成批号。“P”、“Q”、“R”、“S”、“T”和“Z”、表示同一化合物的不同批号。例如,10(P)表示受试化合物是P批的。若未标明批号,则该化合物为P批的。
缩写“ppt”是指沉淀物,表示沉淀物在所示浓度形成。此外,“V形”一词是指沉淀后观察到抑制。
数目和×(即,4×)之后的数值是指化合物测试4次,各次的结果相同。
本发明化合物在常用来评估治疗与淀粉样蛋白聚集相关的疾病(尤其是阿尔茨海默病和其它淀粉样变性)的试剂的体内测定中还显示出良好的活性。在一个测定中,通过皮下注射硝酸银、弗罗因德完全佐剂和静脉内注射淀粉样蛋白促进因子,将淀粉样蛋白导入小鼠脾脏内。在11日内,每日施用硝酸银。从第1日至第11日,将受试化合物每日给予小鼠。在第12日,杀死小鼠,取出脾脏,制备组织标本,用刚果红染色,显微镜下对脾脏中被双折射的刚果红染色的淀粉样蛋白占据的区域的百分比进行定量。在此测试中,相对于未处理的对照,评估出本发明化合物抑制脾脏淀粉样蛋白沉积的活性可达70%。
在另一个体内测试中,用转基因小鼠评估本发明的化合物。小鼠该小鼠具有带感染性蛋白启动子的人β-淀粉样前体蛋白转基因,这在Hsiao等,“相关记忆缺陷、Aβ评估和转基因小鼠的淀粉样斑(Correlative memory deficits,Aβelevation,and amyloid pasques in transgenic mice)”,Science 1966;274:99-102中有描述。这些转基因小鼠在约9月龄时逐步显现出β-淀粉样沉积。至15月龄,出现大量扩散、密集的老年斑,主要在新皮层、嗅球和海马。从8月龄(在就要出现淀粉样沉积之前)起给小鼠口服本发明化合物,继续数月(至约14-18月龄)。然后杀死小鼠,取脑。对脑中的淀粉样物的量作组织学和生化学定量。在此模型中,相对于未处理的对照物,评估出本发明化合物抑制皮层和海马中的淀粉样蛋白积聚的活性可达49%。
上述数据表明,代表性的本发明化合物在用来测定蛋白聚集抑制活性的标准测定方法中显示出活性。本发明化合物显示出优异的特异性(例如,如在BASST、BATYM和BAPA测定中所示)。因此,本发明化合物对临床上抑制淀粉样蛋白聚集和对淀粉样沉积进行成象以供诊断用是非常有用的。本发明的化合物以药剂的形式使用,下面的实施例举例说明典型的组合物。
