Abstract
本发明涉及式(Ⅰ)羧酸衍生物,其中R1-R6、Q、W、X、Y和Z的定义同说明书所述。本发明新化合物适于治疗疾病。
Description
本发明涉及新的羧酸衍生物、其制备方法以及应用。
内皮肽是由21个氨基酸构成的肽,并且是由血管内皮合成和释放的。内皮肽以3种同种型-即ET-1、ET-2和ET-3存在。在本说明书中,“内皮肽”或“ET”表示一种或所有同种型的内皮肽。内皮肽是强有力的血管收缩剂,并且对血管紧张性有很强的作用。已知血管收缩是由于内皮肽与其受体结合所致(《自然》(Nature),332,411-415,1988;《FEBS通讯》(FEBS Letters),231,440-444,1988和《生物化学与生物物理学研究通讯》(Biochem.Biophys.Res.Commun.),154,868-875,1988)。
内皮肽增多或异常释放引起周围、肾和脑血管的持久收缩,这种持久收缩可导致病症。如文献所报道的那样,内皮肽与多种病症有关。这些病症包括:高血压、急性心肌梗塞、肺动脉高血压、雷诺氏综合症、脑血管痉挛、中风、良性前列腺肥大、动脉粥样硬化和哮喘(J.VascularMed.Biology 2,207(1990),《美国医学会会刊》(J.Am.Med.Association)264,2868(1990);《自然》(Nature)344,114(1990);《新英格兰医学杂志》(N.Engl.J.Med.)322,205(1989);《新英格兰医学杂志》(N.Engl.J.Med.)328,1732(1993);《肾单位》(Nephron)66,373(1994),《中风》(Stroke)25,904(1994);《自然》(Nature)365,759(1993);J.Mol.Cell.Cardiol.27,A234(1995);《癌症研究》(Cancer Research)56,663(1996))。
至少有2种内皮肽受体亚型-即ETA和ETB受体已经在文献中描述过(《自然》(Nature)348,732(1990))。因此,能抑制内皮肽与这两种受体结合的物质应该能拮抗内皮肽的生理作用,因而是有价值的药物。
与该文献相反,本发明的目的是提供所谓的混合内皮肽受体拮抗剂。混合内皮肽受体拮抗剂以大约相同的亲和力结合ETA和ETB受体。当亲合力之比ETA∶ETB大于0.05、优选大于0.1,并且小于20、优选小于10时,则可认为对这两种受体的亲和力大约相同。
DE196364046.3描述了能以高度亲和力结合ETA受体和ETB受体的羧酸衍生物。这些化合物的一个特征是例如在β中心被两个苯环对称取代。现在我们已经发现,非常令人惊奇的是,可获得甚至在β中心具有不对称取代(例如甲基/苯基)的混合受体拮抗剂。

本发明还涉及可释放出式Ⅰ化合物的化合物(称为前药)。
优选的前药是在一定条件下例如在体内一些器官如胃、肠、血流或肝脏中的主要条件下能释放出式Ⅰ化合物的前药。
式Ⅰ化合物以及应用制备式Ⅰ化合物的中间体例如式Ⅱ、Ⅲ和Ⅳ化合物可具有一个或多个不对称取代的碳原子。这类化合物可作为纯对映异构体或纯非对映异构体或它们的混合物存在。对映异构纯或非对映异构纯的化合物作为活性组分的应用是优选的。
这类化合物的制备描述在实施例中。
本发明还涉及上述羧酸衍生物在制备药物、尤其是制备ETA和ETB受体抑制剂中的应用。本发明化合物特别适于用作如本文开头所定义的混合拮抗剂。
如WO 96/11914或DE 19636046.3所述,可制得其中W是硫或氧的通式Ⅳ化合物,并且还可以以对映异构纯的形式制得。
通式Ⅲ化合物是已知的,或者可合成制得,例如通过将相应的羧酸或其酯还原、或通过其它常规已知方法来制得。
获得对映异构纯式Ⅳ化合物的另一可能方法是,采用合适的对映异构纯碱,将外消旋或非对映异构式Ⅳ化合物进行常规的外消旋体拆分。合适的这类碱是例如4-氯苯基乙胺和在WO 96/11914中提及的碱。
在式Ⅴ中,R11是卤素或R12-SO2-,其中R12可以是C1-C4-烷基、C1-C4-卤代烷基或苯基。此外,至少一个环单元X或Y或Z是氮。该反应优选在适当碱即将中间体Ⅳ去质子化的碱存在下、在惰性溶剂或稀释剂中、于室温至溶剂沸点温度下进行。
其中R1=COOH的式Ⅰ化合物还可通过用2当量的适当碱把其中R1是COOH的中间体Ⅳ去质子化、并与通式Ⅴ化合物反应而直接制得。该反应也在惰性溶剂中、于室温至溶剂沸点温度下进行。
这类溶剂或稀释剂的实例是分别可任选被氯代的脂族烃、脂环烃和芳香烃,例如己烷、环己烷、石油醚、萘、苯、甲苯、二甲苯、二氯甲烷、氯仿、四氯化碳、氯乙烷和三氯乙烯,醚例如二异丙基醚、二丁基醚、甲基叔丁基醚、环氧丙烷、二氧杂环己烷和四氢呋喃,腈例如乙腈和丙腈,酰胺例如二甲基甲酰胺、二甲基乙酰胺和N-甲基吡咯烷酮,亚砜和砜例如二甲亚砜和四氢噻吩砜。
式Ⅴ化合物是已知的,其中一些可购得,或者可通过常规方法制得。
可以使用的碱有碱金属或碱土金属氢化物例如氢化钠、氢化钾或氢化钙,碳酸盐例如碱金属碳酸盐如碳酸钠或碳酸钾,碱金属或碱土金属氢氧化物例如氢氧化钠或氢氧化钾,有机金属化合物例如丁基锂,或碱金属氨化物例如二异丙基氨基化锂或氨基化锂。
式Ⅰ化合物还可这样制备:使用相应的羧酸即其中R1是COOH的式Ⅰ化合物作为原料,先以常规方法将该原料化合物转化成活化形式例如酰卤、酸酐或酰咪唑,然后再与适当的羟基化合物HOR7反应。该反应可在常用溶剂中进行,并且经常需要加入碱,其中上述碱是合适的。还可将这两个步骤简化,例如通过在脱水剂如碳化二亚胺存在下将该羧酸与该羟基化合物反应来进行简化。
式Ⅰ化合物还可以这样制备:以相应羧酸的盐作为原料,即以其中R1是COR、且R是OM的式Ⅰ化合物作为原料,其中M可以是碱金属阳离子或等价的碱土金属阳离子。可将这些盐与多种式R-A化合物反应,其中A是常规离核性离去基团,例如卤素如氯、溴、碘,或者适当时是被卤素、烷基或卤代烷基取代的芳基磺酰基或烷基磺酰基,例如甲苯磺酰基和甲磺酰基,或其它相当的离去基团。具有反应性取代基A的式R-A化合物是已知的,或者可容易地通过常规方法制得。该反应可在常规溶剂中进行,在碱存在下进行更好,其中上述碱是适当的。
为了制备本发明化合物,有时需要使用常用的已知保护基技术。如果例如R6是4-羟基苯基的话,可首先将该羟基保护成苄基醚,然后在反应顺序中的适当步骤把该保护基裂解掉。
其中R1是四唑基的式Ⅰ化合物可如WO 96/11914所述制得。

将重250-300g的雄性SD大鼠用异戊巴比妥麻醉,进行人工换气,切断迷走神经并取髓。将颈动脉和颈静脉中插入导管。
在对照动物中,静脉内给予1μg/kg ET1,结果导致血压在长时间内显著增加。
在给予ET1之前30分钟,测试动物接受静脉内注射测试化合物(1ml/kg)。为了确定ET拮抗特征,比较测试动物和对照动物的血压改变。
口服测定混合ETA和ETB拮抗剂:
通过口服测试物质将重250-350g的雄性血压正常大鼠(SpragueDawley,Janvier)预治疗。80分钟后,将动物用乌拉坦麻醉,并将颈动脉(为了测定血压)和颈静脉(为了给予大内皮肽/内皮肽1)中插入导管。
稳定期之后,静脉内给予大内皮肽(20μg/kg,给药体积为0.5ml/kg)或ET1(0.3μg/kg,给药体积为0.5ml/kg)。连续记录30分钟血压和心率。以曲线下面积(AUC)计算血压的显著和长时间改变。为了确定测试物的拮抗作用,比较测试物治疗动物与对照动物的AUC。
本发明化合物可以以常规方法口服或非胃肠道给药(皮下给药、静脉内给药、肌内给药、腹膜内给药)。还可以用吸入剂或气雾剂经由鼻咽空间给药。
剂量取决于患者年龄、身体状况和体重、以及给药方式。对于口服给药,活性组分的日剂量一般是约0.5-50mg/kg体重,对于非胃肠道给药,活性组分的日剂量一般是约0.1-10mg/kg体重。
本发明新化合物可在常规固态或液态药物剂型中使用,例如未包衣或(膜)包衣片剂、胶囊剂、粉剂、粒剂、栓剂、溶液剂、软膏剂、霜剂或气雾剂。这些剂型是通过常规方法制得的。可将用于制备剂型的活性组分与常规药物辅料一起加工,所述药物辅料有例如片剂粘结剂、膨胀剂、防腐剂、片剂崩解剂、流动调节剂、增塑剂、湿润剂、分散剂、乳化剂、溶剂、缓释剂、抗氧化剂和/或抛射气体(参见H.Sucker等人:Pharmazeutische Technologie,Thieme-Verlag,Stuttgart,1991)。以这种方式制得的给药剂型一般含有0.1%-90%重量的活性组分。
