Description
本发明涉及外消旋或对映异构纯的4-吡咯烷基衍生物、其制备方法、含有所述衍生物的药物组合物以及它们在预防和治疗疾病中的用途。
更具体地讲,本发明涉及式I化合物、其单一异构体、外消旋或非外消旋混合物:
其中:
Q为=N-或=C(R24)-;
X-Y为-CH2-CH2-、-CH=CH-或-CH2-O-;
R1、R1.1和R1.2彼此独立地选自氢、卤素、(C1-C6)-烷基、卤代-(C1-C6)-烷基、氰基、(C1-C6)-烷氧基和卤代-(C1-C6)-烷氧基;
R21、R22和R23彼此独立地选自氢和卤素;
R24为氢、卤素或甲基;
R3为-C(O)N(H)CH3或-CH2CN;和
R4为氢。
甚至更具体地讲,本发明涉及式I*化合物、其单一异构体、外消旋或非外消旋混合物:
其中
R1为卤素、卤代-(C1-C6)-烷基、氰基、(C1-C6)-烷氧基和卤代-(C1-C6)-烷氧基;
R21、R22、R23和R24彼此独立地选自氢和卤素;
R3为-CONHR5、-CH2CN或-CN;
R4为氢;
R5为甲基;以及
n为0、1、2或3。
申请人发现通式I和I*化合物及其单一异构体、外消旋或非外消旋混合物(下文称为活性化合物)是选择性单胺氧化酶B抑制剂。
单胺氧化酶(MAO,EC 1.4.3.4)是引起内源性单胺类神经递质如多巴胺、5-羟色胺、肾上腺素或去甲肾上腺素和痕量的胺如苯乙胺以及大量胺外源物的氧化脱氨作用的黄素酶。该酶以两种形式存在:MAO-A和MAO-B,这两种形式被不同的基因编码[Bach等人,Proc.Natl.Acad.Sci.USA 85:4934-4938(1988)],并且在组织分布、结构和底物专一性上有所不同。MAO-A对5-羟色胺、章鱼胺、肾上腺素和去甲肾上腺素的亲合力较高;而MAO-B的天然底物为苯乙胺和酪胺。多巴胺被认为可被这两种同种型所氧化。MAO-B广泛分布于包括脑在内的各种器官中[Cesura和Pletscher,Prog.Drug Research 38:171-297(1992)]。脑MAO-B的活性随年龄的增长而增加。已经将这种增加归因于与衰老相关的神经胶质增生[Fowler等人,J.Neural.Transm.49:1-20(1980)]。另外,MAO-B活性在阿尔茨海默氏病患者的脑中显著升高[Dostert等人,Biochem.Pharmacol.38:555-561(1989)],并且已经发现MAO-B活性在老年斑周围的星形胶质细胞中高度表达[Saura等人,Neuroscience 70:755-774(1994)]。在本文中,由于MAO对伯单胺的氧化脱氨作用产生了具有已确定或潜在毒性的物质NH3、醛和H2O2,因而提出了将选择性MAO-B抑制剂用于治疗痴呆和帕金森氏病的理论。抑制MAO-B可引起多巴胺的酶失活减少,并因此可延长神经递质在多巴胺能神经元中的有效性。与年龄相关的退化过程和阿尔茨海默氏病以及帕金森氏病还可以归因于氧化应激,所述的氧化应激由于MAO活性增加以及继而出现的由MAO-B形成的H2O2减少而引起。因此,MAO-B抑制剂可通过减少氧自由基的形成和增加单胺在脑中的水平而起作用。
鉴于MAO-B在上文提及的神经障碍中有所涉及,因此存在有相当大的兴趣来获得一种能够控制这种酶活性的有效和选择性的抑制剂。一些已知的MAO-B抑制剂的药理学例如由Bentué-Ferrer等人进行了讨论[CNSDrugs 6:217-236(1996)]。然而,由于当饮食摄入酪胺时有诱发高血压危象的危险以及可能与其它药物疗法相互作用,该不可逆和非选择性MAO抑制剂活性的主要缺陷是需要遵守饮食预防措施[Gardner等人,J.Clin.Psychiatry 57:99-104(1996)],这些不利因素与可逆性和选择性的MAO抑制剂、特别是MAO-B抑制剂的关联较少。因此,需要有一种具有高度选择性且没有有害的副作用的MAO-B抑制剂,所述的有害副作用是具有低酶选择性的不可逆性MAO抑制剂的特征。

“卤代-(C1-C6)-烷基”或“卤代-(C1-C6)-烷氧基”分别意指在其任意位置被一个或多个如此处所定义的卤素取代的低级烷基或低级烷氧基,所述的低级烷基或低级烷氧基如此处所定义。卤代烷基的实例包括但不局限于1,2-二氟丙基、1,2-二氯丙基、三氟甲基、2,2,2-三氟乙基、2,2,2-三氯乙基和3,3,3-三氟丙基等。“卤代烷氧基”包括三氟甲氧基。
“(C1-C6)-烷氧基”意指-O-R基团,其中R为如此处所定义的低级烷基。烷氧基的实例包括但不局限于甲氧基、乙氧基、异丙氧基等。

根据本发明,流程图1显示了其中R3为-C(O)N(H)CH3的式I化合物,即式I**化合物,的主要合成路线。中间体IV和IVa与衣康酸V的反应优选在温度80℃至200℃之间没有其它物质存在下进行。然后将式IIa和IVa化合物通过本身已知的方法转化为式IIb和VIa的酯。然后通过Williamson-醚合成方法,采用未取代或取代的苄基卤化物、甲苯磺酸酯、甲磺酸酯或三氟甲磺酸酯,将式VIa化合物烷基化。所用的碱可例如是醇化物或碳酸盐,例如碳酸钠、碳酸钾或碳酸铯。溶剂的实例是低级醇、乙腈或低级酮。温度可例如是20℃至回流温度。另一途径是未取代或取代的苄醇与VIa的酚的Mitsunobu-偶合。该反应照例在惰性溶剂如乙醚或四氢呋喃中采用偶氮-二甲酸二烷基酯在膦(如三丁基膦或三苯膦)的存在下进行。
式VIa化合物的水解可通过本身已知的方法进行,所述的方法例如是在酸性条件下如用盐酸进行水解,或者是在碱性条件如用醇水混合物作为溶剂用氢氧化锂、氢氧化钠或氢氧化钾进行水解。
在其中-X-Y-为-CH2-O-的式I**或IIb化合物中,未取代或取代的苄基作为可经氢解裂除的过渡基团。然后将所得的酚VIa和VIb在上文所述的条件下用不同的苄基再次烷基化。如本领域技术人员所熟知的,仅当在上文所述的反应条件下其它取代基对氢解和烷基化反应稳定时该方法才是可能的。
流程图1
式I**或VIb的酰胺可通过将式IIb或VIa的酯在室温(RT)至120℃的温度下、例如在密闭试管中采用在这些条件下惰性的溶剂如二甲氧基乙烷、二噁烷或甲醇中用式R5-NH2的胺氨解而获得。或者,可采用标准方法将式IIa的酸转化为式I**化合物。它们可以用例如酰氯或混合酸酐活化。尤其是对于制备对映纯的衍生物,可采用缩合剂,所述的缩合剂例如是碳化二亚胺如二环己基-碳化二亚胺,或者是苯并三唑衍生物如O-(苯并三唑-1-基)-N,N,N′,N′-四甲基脲鎓六氟磷酸盐(HBTU)。

流程图2
其中LG为离去基团,例如卤素(如Cl、Br或I)或者SnR3或B(OH)2,R3’为-CONHR5或-CH2CN或烷氧羰基。
根据本发明,制备其中-X-Y-为-CH2-O-的通式IV的中间体,即式IVb化合物,的可能方法在流程图3中显示:式XII中间体可通过含对位取代的离去基团的式XI芳族硝基化合物与式X苄醇的亲核取代而获得。在对位的离去基团可例如是卤素(F、Cl、Br、I)、甲苯磺酸根、甲磺酸根或三氟甲磺酸根。这些取代反应可以在没有其它物质存在下进行或在惰性溶剂如甲苯或二甲苯中进行。反应温度可以在50℃至150℃之间。或者,式XII化合物可以通过Williamson-醚合成方法,采用式XIV的对硝基酚和式XIII的苄基卤化物、甲苯磺酸酯、甲磺酸酯或三氟甲磺酸酯制备。所用的碱可例如是醇化物或碳酸盐(碳酸钠、碳酸钾或碳酸铯)。溶剂的实例为低级醇、乙腈或低级酮。温度在20℃至回流温度之间。另一途径为苄醇与式XIV的对硝基酚的Mitsunobu-偶合。该反应照例在惰性溶剂如乙醚或四氢呋喃中采用偶氮-二甲酸二烷基酯在膦如三丁基膦或三苯膦的存在下进行。
式XII的关键中间体可以采用催化氢化反应还原为式IVb的氨基化合物,例如采用铂炭作为催化剂在低级醇、乙酸乙酯或四氢呋喃中进行。另一可选择的方法是通过金属如铁、锡或锌在酸性介质如稀释的盐酸或乙酸中还原硝基。金属也可以被金属盐如氯化锡-(II)替代。
流程图3
其中LG为离去基团,例如卤素、OTf等,且Y为离去基团,例如卤素、OTf等或OH(对于Mitsunobu-偶合)。
根据本发明,制备式IVd(其中-X-Y-为-CH=CH-)和IVc(其中-X-Y-为-CH2-CH2-)中间体的可能方法在流程图4中显示:式XVII中间体可以通过将未取代或取代的式XV芳族醛与式XVI的(4-硝基-苄基)-膦酸二烷基酯在碱如氢化钠的存在下进行烯化反应、生成相应的式XVII的硝基-烯烃而获得。
流程图4
式XVII的关键中间体可以采用催化氢化反应选择性地还原为式IVd的氨基-烯烃,例如采用铂炭作为催化剂在作为溶剂的低级醇、乙酸乙酯或四氢呋喃中进行,或者通过金属或金属盐如氯化锡-(II)进行。式IVc的氨基衍生物可以直接由式XVII的硝基衍生物获得,或者由式IVd的氨基-烯烃通过采用钯炭作为催化剂在作为溶剂的低级醇、乙酸乙酯或四氢呋喃中氢化获得。
或者,式II化合物可以还原为式III的中间体化合物。其可如下进行:首先将式II的酸转化为它们的酯(醇/酸催化),然后于20℃-65℃的温度下采用试剂如硼氢化钠在溶剂如四氢呋喃中还原。式III的醇通过甲磺酸酯或三氟甲磺酸酯活化并与氰化钠或氰化钾在40℃-80℃的温度下反应,得到其中R3为CH2CN的所需式I化合物,即式Ib的腈。
流程图5
通式I化合物还可以以光学纯的形式存在。可以根据本身已知的方法分离为对映体,或者在合成初期例如由式IIa化合物开始通过与光学活性的胺如(+)-或(-)-1-苯乙胺或(+)-或(-)-1-萘基-乙胺形成盐并分步结晶分离非对映的盐而进行分离,或者通过与手性助剂如(+)-或(-)-2-丁醇、(+)-或(-)-1-苯基乙醇或者(+)-或(-)-薄荷醇衍生并色谱和/或结晶分离非对映的产物、随后裂解与手性助剂结合的键而进行分离;或者,在最后阶段在手性相上色谱分离式I的对映异构体而进行分离。另外,式I化合物还可由通过生物转化获得的对映纯的中间体而得到,所述的生物转化例如是式VIa的酯被酶如来自Candida cylindracea的胆甾醇酯酶水解。为了确定吡咯烷酮衍生物的绝对构型,可通过常规的光谱法、例如对单晶的X-射线光谱法来分析纯的非对映的盐或其衍生物。

活性化合物可特别用于治疗和预防阿尔茨海默氏病和老年性痴呆。
这些化合物的药理学活性经下述方法测定:采用Schlaeger和Christensen所描述的操作方法[Cytotechnology 15:1-13(1998)],将编码的人MAO-A和MAO-B的cDNA瞬时转染至EBNA细胞中。在转染后,用Polytron匀浆器将细胞在20mM Tris HCl缓冲液(pH8.0)中匀浆,所述的缓冲液含有0.5mM EGTA和0.5mM苯甲基磺酰氟。于45,000×g离心得到细胞膜,在用含0.5mM EGTA的20mM Tris HCl缓冲液(pH8.0)漂洗两次后,最终将细胞膜重新悬浮于上述缓冲液中并将其等分试样贮存于-80℃备用。
采用由Zhou和Panchuk-Voloshina所描述的方法[AnalyticalBiochemistry 253:169-174(1997)]改良的分光光度测定法在96孔板中测定MAO-A和MAO-B的酶活性。简而言之,于37℃将细胞膜的等分试样在含不同浓度化合物的0.1M磷酸钾缓冲液(pH7.4)中温育30分钟。在此过程后,通过加入MAO底物酪胺和1U/ml辣根过氧化酶(Roche Biochemicals)及80μM的N-乙酰基-3,7-二羟基吩噁嗪(Amplex Red,Molecular Probes)来引发酶反应。将样品于37℃以终体积为200μl再温育30分钟,然后使用SpectraMax板读数仪(Molecular Devices)于570nm波长处测定吸收度。在10μM氯吉兰存在下测定MAO-A的本底(非特异性)吸收度,或者在10μM L-丙炔苯丙胺(deprenyl)存在下测定MAO-B的本底(非特异性)吸收度。由采用9个抑制剂浓度以一式两份得到的抑制曲线、通过使用计算机程序将数据拟合为四参数对数方程来测定IC50值。
本发明的化合物为特异性的MAO-B抑制剂。如在上述测定法中所测定的,优选活性化合物的IC50值为1M或更低,典型地为0.1μM或更低,理想地为0.02μM或更低。
活性化合物可例如以药物制剂的形式用作药物。该药物制剂可以经口服如以片剂、包衣片剂、糖锭剂、硬和软明胶胶囊剂、溶液剂、乳剂或悬浮液的形式给药。然而,还可经直肠(如以栓剂形式)或胃肠道外(如注射溶液的形式)进行给药。
活性化合物可与制药学惰性的无机或有机载体一起处理来生产药物制剂。可以使用乳糖、玉米淀粉或其衍生物、滑石粉、硬脂酸或其盐等来例如作为片剂、包衣片剂、糖锭剂和硬明胶胶囊的载体。适于软明胶胶囊的载体例如是植物油、蜡、脂肪、半固态和液态多元醇等;然而根据活性物质的性质,当为软明胶胶囊时通常不需要载体。适于生产溶液剂和糖浆剂的载体例如是水、多元醇、蔗糖、转化糖和葡萄糖等。辅料如醇、多元醇、甘油和植物油等可用于活性化合物的水溶性盐的注射水溶液,但通常不是必须的。适于栓剂的载体例如是天然油或硬化油、蜡、脂肪、半固态或液态多元醇等。
另外,该药物制剂可含有防腐剂、增溶剂、稳定剂、润湿剂、乳化剂、甜味剂、着色剂、矫味剂、调节渗透压的盐、缓冲剂、掩蔽剂或抗氧化剂。它们还可含有其它有治疗价值的物质。
如前文所提及的,含活性化合物和治疗惰性的赋形剂的药物也是本发明的目标,生产该药物的方法亦如此,所述方法包含将一种或多种活性化合物以及需要的一种或多种其它有治疗价值的物质与一种或多种治疗惰性的载体一起制成盖仑剂型。
剂量可在较宽范围内变化,并且在每个具体病例中当然应该适合于个体的需求。通常,对所有所述适应症的而言,口服或胃肠道外给药的有效剂量为0.01-20mg/kg/天,优选剂量为0.1-10mg/kg/天。因此,对于体重为70kg的成人,每日剂量为0.7-1400mg/天,优选为7-700mg/天。
