本发明涉及式I的化合物

其中A1、A2、R1、R2、R3、X和n如下文所定义,该化合物是用于治疗和预防疾病例如心血管疾病如高血压、心绞痛、心功能不足、血栓形成或动脉粥样硬化的有价值的药物活性化合物。式I化合物可以调节体内环鸟苷酸(cGMP)的产生,可用于治疗和预防与cGMP平衡紊乱有关的疾病。本发明还涉及式I化合物的制备方法、其用于治疗和预防上述疾病的用途及其在制备用于该目的的药物中的用途,以及含有式I化合物的药物制剂。
cGMP是一种重要的细胞内信使,它通过调节cGMP依赖型蛋白激酶,磷酸二酯酶和离子通道而引发多种不同的作用。例如,松弛平滑肌、抑制血小板激活和抑制平滑肌细胞的增殖及白细胞的粘着。cGMP由颗粒状和可溶性鸟苷酸环化酶在受到各种细胞外和细胞内的刺激时产生。对于颗粒状鸟苷酸环化酶,刺激主要由肽信使引起,例如心房肽或脑钠尿肽。可溶性鸟苷酸环化酶(sGC)是胞质异源二聚体血红素蛋白,它主要由一族由酶催化形成的低分子量的因子进行调控。最重要的刺激物是一氧化氮(NO)或与其密切相关的物质。其它因子如一氧化碳或羟基的功能还不很清楚。目前认为,NO与血红素结合形成五配位的血红素-亚硝酰配合物是通过NO激活的激活机制。所伴随的以基础状态与铁结合的组氨酸的释放将酶转变成活性构象。
活性的可溶性鸟苷酸环化酶由一个α亚单位和一个β亚单位组成。已发现了多种亚单位亚型,它们彼此在序列、组织特异性分布以及在不同的发育阶段表达方面存在差异。α1和β1亚型主要在脑和肺内表达,而β2主要出现在肝和肾中。α2亚型存在于人类胎儿的脑中。从人脑中分离出了称为α3和β3的亚单位,它们与α1和β1是同源的。最近的研究发现了α2i亚单位,其在催化结构域中含有插入片段。所有亚单位在催化结构域区域显示高度的同源性。据推测,酶在每个异源二聚体中含有一个血红素,其通过β1-Cys-78和/或β1-His-105结合并且是调节中心的一部分。
在病理条件下,鸟苷酸环化酶活化因子的形成可能会减少,或者它们的降解会由于自由基的增加而加速。所造成的sGC激活的下降会通过cGMP-介导的细胞应答的减弱而导致例如血压升高、血小板激活或细胞增殖和细胞粘着的增加。结果导致出现内皮功能障碍、动脉粥样硬化、高血压、稳定或不稳定心绞痛、血栓形成、心肌梗塞、中风或勃起功能障碍。对sGC的药理学刺激能够会使cGMP的产生正常化,因此可以治疗和/或预防所述疾病。
为了对sGC进行药理学刺激,迄今为止所使用的几乎全部是其活性是基于中间体NO释放的化合物,例如有机硝酸酯。该治疗的缺点是出现耐受性和活性的降低,因此需要更高的剂量。
Vesely在一系列出版物中描述了各种不通过NO释放起作用的sGC刺激剂。但是,这些化合物中大部分是激素、植物激素、维生素或天然化合物如蜥蜴毒,它们仅对溶胞产物中的cGMP形成有很弱的作用(D.L.Vesely,《欧洲临床研究杂志》(Eur.J.Clin.Invest)15(1985)258;D.L.Vesely,《生物化学生物物理学研究通讯》(Biochem.Biophys.Res.Comm.)88(1979)1244)。Ignarro等(《药理学进展》(Adv.Pharmacol.)26(1994)35)证实了通过原卟啉IX刺激不含血红素的鸟苷酸环化酶。Pettibone等(《欧洲药理学杂志》(Eur.J.Pharmacol.)116(1985)307)描述了碘化二苯六氟磷酸盐的抗高血压作用,并将其归因于对sGC的刺激作用。根据Yu等的描述(《英国药理学杂志》(Brit.J.Pharmacol.)114(1995)1587),对离体大鼠主动脉具有松弛作用的异甘草根亭配基也可以激活sGC。Ko等(《血液》(Blood)84(1994)4226)、Yu等(《生物化学杂志》(Biochem.J.)306(1995)787)和Wu等(《英国药理学杂志》(Brit.J.Pharmacol.)116(1995)1973)证实了1-苄基-3-(5-羟基甲基-2呋喃基)吲唑的sGC刺激活性,并证实了其抗增殖和抑制血小板形成的作用。EP-A-908456和DE-A-19744027中描述了具有sGC刺激活性的吡唑和稠合的吡唑类化合物。
在文献中记载了一系列在N-芳基上带有硫取代基的2-磺酰基氨基苯甲酸N-芳基酰胺类化合物。这些在N-芳基通常还带有其它易被氧化的取代基例如两个彼此处于对位的羟基(在该情况下可以看作是氢醌衍生物)的化合物是制备照相用材料的辅料(参见,例如化学文摘119,105757;120,41858;123,70224或126,257007)。如果考虑孤立的结构单元,则这些已知化合物中的N-芳基相当于式I中当A1表示在2位和5位带有羟基(或氧取代基)的1,4-亚苯基并且n是0时的基团R1-S(O)n-A1。英国专利公开号876526(化学文摘56,15432e)公开了可用于保护羊毛防止蠹虫的3,5-二氯-2-甲基磺酰基氨基苯甲酸N-(5-氯-2-(4-氯苯基巯基)-苯基)-酰胺。GB-A-876526所包含的化合物相当于同时满足如下条件的式I化合物:其中含有带有基团C(=X)-NH-和NH-SO2R2的碳原子的环A1与R3基团合在一起是带有1-4个选自氯和溴的卤原子的苯环,R2是(C1-C4)-烷基,X是氧并且基团R1-S(O)n-A1-是被卤素和/或三氟甲基取代的并且还可以被甲基或(C1-C4)-烷氧基取代的苯基巯基苯基基团(=苯硫基苯基-),并且卤原子和三氟甲基的总数大于2。没有公开这些已知的2-磺酰基氨基苯甲酸N-芳基酰胺类化合物的药理学活性。
令人惊奇的是,我们发现本发明的化合物对鸟苷酸环化酶有很强的激活作用,因此可用于治疗和预防与低cGMP水平有关的疾病。
因此,本发明涉及式I化合物

本发明还涉及制备式I化合物的方法,该方法如下所述并且通过该方法可以制得本发明的化合物。根据反应方案1,本发明的化合物可以通过例如,首先将式II的氨基羧酸与式R2-SO2-Cl的磺酰氯或磺酸酐在碱的存在下在溶剂例如水、吡啶或醚中反应制得。适宜的碱是无机碱如碳酸钠或有机碱如吡啶或三乙胺。然后可以将得到的式III的磺酰基氨基甲酸通过例如与氯化试剂如五氯化磷、三氯氧磷或亚硫酰氯在惰性溶剂中反应进行活化,生成式IV的酰氯,然后将其与芳基胺反应。式III化合物中的羧酸基团的活化还可以通过不同的方式来进行,例如,通过本领域技术人员熟知的在肽化学中形成酰胺键的多种方法之一来进行,例如,转变成混合酸酐或活泼酯或使用碳二亚胺如二环己基碳二亚胺。
活化的磺酰基氨基甲酸与芳基胺的反应优选在惰性溶剂如吡啶、四氢呋喃或甲苯中、在含或不含惰性辅助碱如叔胺或吡啶的存在下进行。如果在与活化羧酸的反应中所用的芳基胺已经含有所需的取代基R1-S(O)n,则反应可以直接形成最终的式I化合物。基团R1-S(O)n中的n是1或2的式I化合物还可以通过将活化的羧酸与式R1-S-A1-NH2的巯基取代的芳基胺反应然后将式V化合物中的巯基在常规条件下,例如用过氧化物如过氧化氢或过酸如3-氯过苯甲酸或单过氧苯二甲酸在溶剂如二氯甲烷或丙酮中氧化制得。还可以首先将活化的羧酸与式A1-NH2的芳基胺反应。然后可以将形成的式VI的反应产物在常规条件下氯磺化并将氯磺酰基在常规条件下转变成基团R1-SO2,例如与适宜的胺直接反应或在溶剂如N-甲基吡咯烷酮、二甲基甲酰胺、甲苯或乙醚中反应,反应中可以选择性地存在辅助碱。采用类似的方式,可以将活化的羧酸与式F-SO2-A1-NH2的氟磺酰基芳基胺反应,所得到的式VII的氟磺酰基中间体可以在常规条件下转变成本发明的式I化合物。

本发明的式I化合物还可以通过将活化的磺酰基氨基羧酸,例如反应方案1中所示的式IV的酰氯与在硫原子上未被取代的式H2N-A1-SH的巯基芳基胺反应制得。然后可以将得到的式VIII的产物在亲核取代反应中在硫原子上用烷基卤化物或芳基卤化物或其它的活泼化合物在常规条件下烷基化或芳基化,然后,如需要,将硫进行氧化得到以上在式V化合物中所描述的亚砜或砜(参见反应方案2)。
反应方案2
式I化合物还可以通过,例如首先将适宜取代的式IX的硝基羧酸通过转变成相应的式X的酰氯或通过其它方法活化,然后将其与式R1-S(O)n-A1-NH2的取代的芳基胺按照与以上描述类似的方法反应制得(参见反应方案3)。在此,也可以使用式F-SO2-A1-NH2的氟磺酰基芳基胺作为芳基胺,在所得到的式XI的N-(氟磺酰基芳基)-甲酰胺中,可以将氟磺酰基在常规条件下,例如用式HNR5R6的胺转变成本发明的R1-SO2基团。
反应方案3
在将得到的式XII的硝基中间体中的硝基还原成氨基之前,可以利用硝基对环A2的活化作用将适宜的基团R3如卤原子通过与亲核试剂如胺反应用不同的基团R3所代替。将硝基还原生成氨基可以通过,例如在贵金属催化剂或者优选在阮内镍的存在下在溶剂例如乙醇、冰乙酸或氯化氢的乙醇溶液中催化氢化来完成,或者通过用贱金属如锌、锡或铁在酸存在下还原来完成。还原还可以用例如氯化锡(II)或通过与连二亚硫酸钠反应、优选在甲醇、四氢呋喃和水的混合溶剂中反应来完成。式XIII还原产物中氨基的磺酰化可以用活泼的磺酸衍生物按照与上述反应类似的方法进行,例如与磺酰氯在吡啶中反应,最后生成式I的化合物。
其中X是通过单键与基团A1中的环碳原子连接的氮原子并且所述的环碳原子紧邻A1中带有基团-NH-C(=X)-的碳原子的式I化合物,即Ii的苯并咪唑衍生物,可以通过例如将按照以上反应方案1的描述制得的活化的磺酰基氨基羧酸衍生物,例如IV的酰氯(或者,与反应方案3类似,为硝基甲酸衍生物)与1,2-二氨基芳烃在脱水剂如亚硫酰氯或五氯化磷的存在下反应制得(参见反应方案4)。反应通常在惰性溶剂例如烃如甲苯或二甲苯中进行。1,2-二氨基芳烃可以已经含有最终的基团R1-S(O)n或其前体基团例如基团R1-S。然后可以按照以上描述进行随后的步骤,例如在硫原子上的反应。正因为如此,可以使用未取代的1,2-二氨基芳烃并可以将得到的式XIV的产物用例如氯磺酸进行氯磺化,然后可以将得到的磺酰氯通过例如与适宜的胺反应转变成含有基团R1-SO2的最终化合物。

药理学研究
1)可溶性鸟苷酸环化酶的激活
本发明化合物对催化三磷酸鸟苷(GTP)向环鸟苷酸(cGMP)和焦磷酸转变的可溶性鸟苷酸环化酶(sGC)的激活通过来自Amersham的酶免疫试验(EIA)来测量。为此,将待测试的物质首先与sGC一起在微滴度板中保温,然后测定所形成的cGMP的量。
所用的sGC从牛肺中分离(参见《酶学方法》(Methods inEnzymology),195卷,377页)。试验溶液(每孔100μl)含有50m三乙醇胺(TEA)缓冲液(pH7.5)、3mM MgCl2、3mM还原的谷胱甘肽(GSH)、0.1mM GTP、1mM 3-异丁基-1-甲基黄嘌呤(IBMX)、适当稀释的酶溶液和待测试物质或溶剂(对照实验)。将待测试的物质溶于二甲亚砜(DMSO),然后将溶液用DMSO/水稀释,从而使待测试物质在测试溶液中的最终浓度c具有表中给定的数值。测试溶液中的DMSO浓度为5%(v/v)。通过加入sGC引发反应。将反应混合物在37℃保温15至20分钟,然后通过用冰冷却并加入终止试剂(50mM EDTA,pH8.0)停止反应。取出50μl等分试样并用Amersham cGMP-EIA试剂盒的乙酰化方案测定cGMP含量。在微滴度板读数器中测定样品在450nm(参考波长620nm)的吸收值。用在相同测试条件下获得的标准曲线确定cGMP浓度。试验物质对sGC的激活用在对照实验(用溶剂代替测试物质)中测得的基础酶活性的n倍刺激来表示(用公式n倍刺激=[cGMP]试验物质/[cGMP]对照来计算)。

2)大鼠主动脉的松弛
为了进行该试验,将血压正常的雄性Wistar-Kyoto大鼠通过向颈部注射空气处死。通过中间胸骨切开术打开腹腔和胸腔。随后取出下行主动脉,除去结缔组织并分成8个长度约为4mm的环。将镊子的尖端插入其中4个环的腔内。通过小心地将环在镊子尖端旋转除去内皮。将所有8个主动脉环(4个有内皮,4个没有内皮)悬挂在37℃恒温的器官浴(Schuler-Organbad;Hugo Sachs Elektronik)中以测定等长收缩状况。将环在1g的静息张力下在碳酸化的(95%O2;5%CO2)pH7.4的Krebs-Henseleit溶液(组成:Na+144.0mM;K+5.9mM;Cl-126.9mM;Ca2+1.6mM;Mg2+1.2mM;H2PO4 -1.2mM;SO4 2-1.2mM;HCO3 -25.0mM;D-葡萄糖11.1mM)中校准30分钟。此外,还向Krebs-Henseleit溶液中加入1μmol/l的消炎痛以抑制前列腺素的生物合成。然后通过加入苯福林(在溶液中的浓度为1μM)使环预收缩,然后通过加入乙酰胆碱(在溶液中的浓度为1μM)测试内皮依赖性的松弛或内皮功能的丧失。经过30分钟的清洗期后,通过加入苯福林(1μM)使环再次预收缩,然后通过施用累积剂量的式I的试验物质来测定它的松弛作用。通过常规方法对数据进行评估。所给出的是抑制收缩达50%的浓度IC50(50%松弛)。
