Abstract
本发明提供能抑制5-羟色胺及去甲肾上腺素摄取的3-芳氧基-3-取代的丙胺的制备方法。
Description
本发明与新的3-芳氧基-3-取代的丙胺有关,也与将它们应用于抑制5-羟色胺及去甲肾上腺素的摄取方面有关。
在过去十年中,对单胺的摄取与各种疾病和状态的关系进行了评价和研究。例如,氟苯氧丙胺(d1-N-甲基-γ-[4-(三氟甲基)苯氧基]苯丙胺)盐酸盐是有选择性和特异性的5-羟色胺摄取抑制剂,目前对抑郁、焦虑、食欲不振以及其他失调的治疗正在进行临床评价。与此相似,托莫西汀盐酸盐(tomoxetine hydrochloride,(-)-N-甲基-γ-(2-甲基苯氧基)苯丙胺盐酸盐)是有选择性和特异性的去甲肾上腺素摄取抑制剂,正对其抗抑郁作用进行临床观察。在美国专利4,018,895;4,194,009和4,314,081等号公开的许多化合物中,这些化合物是有效的但对于某一特异的单胺抑制剂的摄取它们是选择性的阻滞剂。
本发明提出新的3-芳氧基-3-取代的丙胺,它对5-羟色胺和去甲肾上腺素的摄取均具有明显的抑制作用。
本发明提供具有以下化学通式的化合物及其可用作药物的酸加成盐。
其中
R1是C5-C7环烷基,噻吩基、卤代噻吩基、(C1-C4烷基)噻吩基,呋喃基,吡啶基或噻唑基;
R2和R3各自可独立地是氢或甲基;
R4可独立地是卤素、C1-C4烷、C1-C3烷氧基或三氟甲基;
R5可独立地是卤素、C1-C4烷基或三氟甲基;
m是0,1或2;
n是0或1。
本发明还提供含有上式的化合物和可用于药剂的载体、稀释剂或赋形剂的药用配方。
本发明还进一步提供了应用本发明化合物有选择地抑制5-羟色胺和去甲肾上腺素摄取的方法,以及治疗哺乳动物各种与5-羟色胺和去甲肾上腺素神经传递降低有关的疾患(包括肥胖、抑郁、酒精中毒、疼痛、丧失记忆、焦虑、吸烟)的方法。
上述化学式中,C1-C4烷基代表含1到4个碳原子的直链或带支链的烷基。典型的C1-C4烷基团包括甲基,乙基,正丙基,异丙基,正丁基,异丁基,仲丁基和叔丁基。
C1-C3烷氧基代表甲氧基,乙氧基,正丙氧基或异丙氧基卤素表示氟、氯、溴或碘。
当Ar是萘基时,它可以是1-萘基或2-萘基。
当R1是噻吩基时,它可以是2-噻吩基,也可是3-噻吩基,当R是呋喃基时,它可以是2-呋喃基,也可是3-呋喃基,当R1是吡啶基时,它可以是2-吡啶基、3-吡啶基或是4-吡啶基,当R1是噻唑基时,它可以是2-噻唑基,4-噻唑基或是5-噻唑基。
(C1-C4烷基)噻吩基代表在噻吩环上有C1-C4烷基单一取代的噻吩基。典型的(C1-C4烷基)噻吩基包括4-甲基-2-噻吩基,3-乙基-2-噻吩基,2-甲基-3-噻吩基,4-丙基-3-噻吩基,5-正丁基-2-噻吩基,4-甲基-3-噻吩基,3-甲基-2-噻吩基等。
卤代噻吩基代表在噻吩环上有卤素取代基的单一取代的噻吩基。典型的卤代噻吩基团包括3-氯-2-噻吩基,4-溴-3-噻吩基,2-碘-3-噻吩基,5-碘-3-噻吩基,4-氟-2-噻吩基,2-溴-3-噻吩基,4-氯-2-噻吩基等。
虽然据信本发明的所有化合物在哺乳动物中均能抑制5-羟色胺及去甲肾上腺素的摄取,但只有其中某些化合物作为这种用途较为优越。较好的是R1是卤代噻吩基、(C1-C4烷基)噻吩基,特别是噻吩基更好。此外,R2及R3中,一个是氢而另一个是甲基较好。R2与R3均不是甲基的这些化合物也能较好地抑制哺乳动物对去甲肾上腺素的摄取。本发明中其他的有利选择将在以后谈到。
因此,上述化合物可以各个立体异构体形式和外消旋混合物形式存在。因此,本发明的化合物将不仅包括d1-外消旋体,而且也包括它们各自有旋光活性的d-及1-异构体。
如前所述,本发明包括由上式所定义的化合物的可作药用的酸加成盐。由于本发明的化合物是胺类,所以它们属碱性,因而可与各种无机和有机酸类反应,形成可作药用的酸加成盐。因为本发明的游离胺类在室温下一般呈油状,为便于处理,最好将该游离胺类转变成在室温下通常呈固体的相应的可作药用的酸加成盐。用以形成这种盐的酸类包括无机酸如盐酸、氢溴酸、氢碘酸、硫酸和磷酸,以及有机酸如对甲苯磺酸、甲磺酸、草酸、对溴苯磺酸、碳酸、琥珀酸、柠檬酸、苯甲酸和醋酸以及有关的无机和有机酸类。因此上述可作药用的盐类包括硫酸盐、焦硫酸盐、硫酸氢盐、亚硫酸盐、亚硫酸氢盐、磷酸盐、磷酸氢盐、磷酸二氢盐、偏磷酸盐、焦磷酸盐、氯化物、溴化物、碘化物、乙酸盐、丙酸盐、癸酸盐、辛酸盐、丙烯酸盐、甲酸盐、异丁酸盐、癸酸盐、庚酸盐、丙炔酸盐、草酸盐、丙二酸盐、琥珀酸盐、辛二酸盐、癸二酸盐、富马酸盐、马来酸盐、丁炔-1,4-二酸盐、己炔-1,6-二酸盐、苯甲酸盐、氯苯甲酸盐、甲基苯甲酸盐、二硝基苯甲酸盐、羟基苯甲酸盐、甲氧基苯甲酸盐、邻苯二甲酸盐、对苯二酸盐、磺酸盐、二甲苯碘酸盐、苯乙酸盐、苯丙酸盐、苯丁酸盐、柠檬酸盐、乳酸盐、β-羟基丁酸盐、乙醇酸盐、

本发明的化合物可通过该技术领域已知的通常方法制备。最好用碱金属氢化物处理羟基中间体,以形成相应的碱金属盐,然后与含有易离去基团的适宜化合物反应,得到本发明相应的3-芳氧基-3-取代的丙胺。这一反应可由下式来表示:
其中M是碱金属,R1、R2、R3及Ar的定义如前述,X和Y中一个是羟基而另一个是易离去基团(如对甲苯磺酰基、甲磺酰基、氧化三苯膦、卤素等)。以X是羟基而Y是卤素为佳。碱金属氢化物可由其强度足以产生阴离子的其他碱所代替。
该反应是用大约等克分子数到略过量的碱金属氢化物与醇化合,以提供相应的碱金属盐,典型的碱金属氢化物包括氢化钠和氢化钾。然后使该化合物与等克分子数至稍过量的具有易离去基团的化合物进行反应。该反应在合适的非质子传递溶剂如N,N-二甲基乙酰胺及有关的溶剂中进行。当在25℃到150℃范围内进行反应时,反应在大约10分钟到24小时后基本完成。最好是反应在约75℃到125℃进行,反应混合物在约30分钟到6小时内完成。产品同样可以用一般的方法进行分离。典型的做法是:混合物用水稀释并用与水不混溶的有机溶剂如乙醚,乙酸乙酯,氯仿等进行提取。将有机提取液合并,并干燥之。蒸发有机溶剂后,如果需要,可将分离出来的残余物进一步以标准的技术进行纯化,如从普通的溶剂中结晶,或用固体载体(如硅胶或氧化铝)进行色谱提纯。
其中R2和R3中一个是氢而另一个是甲基的本发明化合物,最好由相应的N,N-二甲基丙胺进行脱甲基而制成。最好用一试剂如氯甲酸苯酯或氯甲酸三氯乙酯与N,N-二甲基丙胺反应,以生成相应的中间产物,然后在碱中进行水解,得到相应的N-甲基丙胺。
如前所述,本发明的外消旋体的旋光异构体也属于本发明的部分。该旋光异构体可由它们相应的光学活性前体物质按上述步骤进行制备,或者将外消旋混合物进行拆解。这种拆解可在拆解试剂存在下通过色谱或反复结晶而实现。特别有用的拆解试剂有二苯甲酰基-d-和-1-酒石酸等。
在合成本发明化合物中用作起始物的化合物也可用一般的方法进行制备。最好用标准的曼尼期反应条件从适宜的酮、甲醛及二甲基胺合成相应的曼尼期碱,然后用氢化物如硼氢化钠作为还原剂,用一般的还原条件进行还原。含有离去基团的类似物也可用已知步骤进行制备,或是从各有机化学厂购买。
本发明的可作药用的酸加成盐一般是用本发明的3-芳氧基-3-取代的丙胺与等克分子数或过量的酸反应得到。反应物通常在互溶剂(如乙醚或苯)中反应,而所得的盐通常经1小时到10天内从溶液中析出,并可经过滤将其分离。
以下实例进一步说明本发明的化合物及其合成的方法。无论如何不应理解为这些实例是在任何方面限制本发明的范围也不应作这样的解释。

如上所述,本发明的化合物可用于抑制5-羟色胺的摄取。由此,本发明的另一内容是提供在哺乳动物中抑制5-羟色胺摄取的方法,它包括给需要增加5-羟色胺神经传递作用的哺乳动物施用药学上有效量的本发明化合物。
本发明的化合物还有抑制去甲肾上腺素摄取的作用。因此,本发明的另一内容是提供在哺乳动中抑制去甲肾上腺素摄取的方法,它包括给需要增加去甲肾上腺素神经使递作用的哺乳动物施用药学上有效量的本发明化合物。
此处所用“药学上有效量”是指能抑制5-羟色胺或去甲肾上腺素摄取的本发明化合物的量。当然,按本发明施用的化合物的特定剂量取决于病例的特定情况,其中包括所施用的化合物,施用途经,被治疗患者的具体情况以及类似的考虑。化合物可通过各种途径施用,包括口服,经直肠,经皮内,皮下,静脉内,肌肉内或鼻腔内等途径。意外地发现,本发明的化合物不仅可以抑制哺乳动物中5-羟色胺的摄取,而且也可以抑制去甲肾上腺素的摄取。口服有很好的生物有效性而不失去对5-羟色胺及去甲肾上腺素的摄取的有效抑制作用,这是本发明化合物特殊的性能。本发明化合物另一个特殊的性能是它们对哺乳动物的毒性低。一般每日剂量是含有本发明有效化合物从约0.01mg/kg到约20mg/kg。以每日剂量从0.05到10mg/kg为佳,理想的是从约0.1到约5mg/kg。
各种生理功能被证明是受脑5-羟色胺能和去甲肾上腺能神经系统影响。因此,相信用本发明的化合物可以治疗哺乳动物中与神经系统有关的各种病症,如肥胖、抑郁、酒精中毒、疼痛、丧失记忆、焦虑及吸烟。因此,本发明也提供在上述情况下以抑制哺乳动物对5-羟色胺和去甲肾上腺素的摄取从而治疗上述疾患的方法。
进行下述试验,以证明本发明的化合物抑制5-羟色胺和去甲肾上腺素摄取的能力。这一通用方法由Wong等人提出发表在Drug Development Research 6∶397-403(1985)上。

触突小体对3H-5-羟色胺(3H-5HT)和14C-1-去甲肾上腺素(C-NE)的摄取用下法测定。将皮质触突小体(相当于1mg的蛋白质)在含有10mM葡萄糖,0.1mM异烟酰异丙肼,1mM抗坏血酸,0.17mM EDTA,50mM3H-5HT和100nM14C-NE的1ml柯氏(Krebs)-重碳酸盐介质中于37℃保温5分钟。立即用2ml冰冷的柯氏(Krebs)-重碳酸盐缓冲液稀释反应混合物并在真空下用细胞收集器(Brandel,Gaithersburg,MD)过滤。滤器用约5ml冰冷的0.9%盐水洗两次并移入含有10ml闪烁液(PCS,Amersham,Arlington Heights,IL)的计数瓶中。放射活性通过液体闪烁分光光度计来测量。3H-5HT和14C-NE在4℃下的累积代表底数并从所有样品中减去。
本发明各个化合物的评价结果列于下面表1中。表中1-4栏在采取栏头所列出的化学式时确定了被评价化合物的结构式;第5栏表明被评价化合物的盐的形式(如果存在时);第6和第7栏指
出分别抑制5-羟色胺或去甲肾上腺素50%时所需受试化合物的浓度[10-9M(nM)],在表中用IC50表示。括弧中的数字代表在1000nM时抑制的百分数。(表1见后)
本发明化合物最好在使用前配制。因此,本发明的另一内容是提供药用配方,该配方包括本发明的化合物及可作药用的载体、稀释剂和赋形剂。
现用的药用配方是按已知方法并应用熟知和易得的成分配制而得。为配制本发明的组合物,通常将有效成分与载体混合,或用载体稀释,或装在载体之内,后者可以是胶囊、药囊、纸或其他容器。当载体用作稀释剂时,它可以是固体、半固体或液体物质,其作用是作为有效成分的媒介物、赋形剂或介质。因之,组合物可以是以下的形式:片剂、丸剂、粉剂、锭剂、药囊剂、扁囊剂、剂、悬浮剂、乳剂、溶液剂、糖浆剂、气雾剂(作为固体或在液体介质内),软膏剂(例如,按重量计其有效成分可达到10%),此外还可应用软及硬胶囊剂,栓剂、灭菌注射用溶液以及灭菌包装的粉剂。
某些适宜的载体、赋形剂及稀释剂的例子包括乳糖、葡萄糖、蔗糖、山梨糖醇、甘露糖醇、淀粉、阿拉伯胶、磷酸钙、藻酸盐、黄蓍胶、白明胶、硅酸钙、微晶纤维素、聚乙烯吡咯烷酮、纤维素、水糖浆、甲基纤维素、甲基和丙基羟基苯甲酸酯、滑石粉、硬脂酸镁和矿物油。配方可另外含有润滑剂、湿润剂、乳化剂和悬剂,防腐剂、增甜剂或调味剂。本发明的组合物可用本技术领域已知的方法配制成施用的病人后其有效成分的释放呈快速、缓释或延效的制剂。
该组合物最好配制成单位剂量形式,每一剂量含有效成分5到500mg,更常用的是约25至300mg。“单位剂量形式”一词实际上是指适用于人及其他哺乳动物作为单次剂量的独立的单位,每一单位含有予先确定的经计算能产生所需要治疗效果的有效物质以及与之相结合的合适的药用载体。
