作为上述反应方法的或选方法,也可以通过式(I-b)中间体与式R8a-OH中间体在酸性介质中反应制备式(I-c)化合物。
还可以通过在酸性介质例如硫酸中,将式(I-b)化合物与C1-16烷基-CN进行Ritter型反应,将式(I-b)化合物转化为式(I-g)化合物。再者,可以通过式(I-b)化合物与乙酸铵反应,然后用氨水处理,将式(I-b)化合物转化为其中R11和R12为氢的式(I-g)化合物。
通过将式(I-b)化合物置于适当的还原条件下,例如在合适的还原剂如硼氢化钠存在下、在三氟乙酸中搅拌,或者在甲酰胺存在下、在乙酸中搅拌式(I-b)化合物,还可以将式(I-b)化合物转化为式(I-d)化合物。再者,通过将式(I-d)化合物与式(V)化合物在合适的溶剂例如二甘醇二甲醚中、在碱例如丁醇钾存在下进行反应,可以将其中R8是氢的式(I-d)化合物转化为其中R8b是C1-6烷基的式(I-e)化合物。
通过将相应的式(I-a)化合物与象五硫化磷这样的试剂或者Lawesson′s试剂在合适的溶剂例如吡啶中反应,可以制备其中X是硫的式(I)化合物,即式(I-f)化合物。
通过将式(VI)的硝酮与羧酸的酸酐例如乙酸酐反应,如此在喹啉部分的2位形成相应的酯,可以制备其中R1是氢并且X是氧的式(I)化合物,即式(I-a-1)化合物。所述喹啉酯可以就地用碱例如碳酸钾水解成相应的喹啉酮。
或者,通过将式(VI)的硝酮与含有磺酰基的亲电子试剂如对甲苯磺酰氯在碱例如碳酸钾水溶液中反应,可以制备式(I-a-1)化合物。该反应最初形成2-羟基喹啉衍生物,然后其互变异构形成所需的喹啉酮衍生物。采用本领域已知的相转移催化剂可以提高反应速度。
还可以通过式(VI)化合物的分子间光化学重排制备式(I-a-1)化合物。所述重排可以通过将试剂溶解在反应惰性溶剂中并在366nm照射进行。有利的是使用脱气溶解并且在惰性气氛例如无氧的氩或氮气氛下进行,以使不希望的副反应减至最小或者减少量子的产生。
还可以通过本领域已知的反应或者官能团转化进行式(I)化合物的相互转化。在上文中已经描述了许多这种转化。其他的实例是将羧酸酯水解成相应的羧酸或醇;将酰胺水解成相应的羧酸或胺;将腈水解成相应的酰胺;采用本领域已知的重氮化反应,然后用氢置换重氮基,可以用氢置换咪唑或苯基上的氨基;可以将醇转化为酯和醚;将伯胺转化为仲胺或叔胺;将双键氢化成相应的单键。
通过式(VIII)的喹啉酮衍生物与式(IX)中间体或其官能衍生物在合适的条件下反应,可以制备式(III)的中间体,所述合适的条件是例如强酸如在合适溶剂中的多磷酸。通过在强酸例如多磷酸存在下进行搅拌,可以将式(VII)中间体环化形成式(VIII)中间体。在所述的环化反应之后可以任意地进行氧化步骤,该氧化反应可以通过在合适的溶剂例如卤代芳族溶剂如溴苯中、在氧化剂例如溴或碘存在下,搅拌环化后形成的中间体进行。在此阶段,可以采用本领域已知的官能团转化反应适当地改变R1取代基。
其中虚线是一个键、R1和R17是氢并且X是氧的式(III)中间体,即式(III-a-1)中间体,可以由式(XVII)中间体开始制备,后者可以方便地通过保护相应的酮进行制备。在碱例如氢氧化钠存在下、在合适的溶剂例如醇如甲醇中,将所述式(XVII)中间体与式(XVIII)中间体一起搅拌。通过将中间体(XVI)与酸例如TiCl3在水存在下进行搅拌,可以使所得式(XVI)中间体进行酮缩醇水解并使异噁唑部分开环。然后用乙酸酐制备式(XV)中间体,后者在碱例如叔丁醇钾存在下环合。
采用本领域已知的N-烷基化方法,可以容易地将式(III-a-1)中间体转化式(III-a)中间体,即其中虚线表示一个键、X是氧、R17是氢并且R1不是氢的式(III)中间体。
或选的制备其中X是氧并且R1是氢的式(III-a-1)中间体的方法是由式(XVI)中间体开始,后者可以方便地采用催化氢化条件,例如在反应惰性溶剂如四氢呋喃中、用氢气和披钯碳进行催化氢化,转化为式(XIX)中间体。通过将式(XIX)中间进行乙酰化反应,例如在反应惰性溶剂如甲苯中、用羧酸酐如乙酸酐进行处理,然后在反应惰性溶剂例如1,2-二甲氧基乙烷中、用碱例如叔丁醇钾处理,将式(XIX)中间体转化为式(XX)中间体。通过在酸性条件下处理式(XX)中间体可以得到式(III-a-1)中间体。
通过其中W是合适的离去基团例如卤素的式(X)中间体与式(XI)的中间体酮反应,可以制备式(II)中间体。通过将式(X)中间体转化为有机金属化合物,将其与强碱如丁基锂一起搅拌,然后加入式(XI)的中间体酮进行该反应。进行该反应首先形成羟基衍生物(即R8是羟基),所述羟基衍生物可以通过本领域已知的(官能团)转化反应,转化为其中R8具有另一种定义的其他中间体。
通过式(XII)的喹啉衍生物与合适氧化剂如间氯过氧化苯甲酸或H2O2在合适的溶剂例如二氯甲烷中进行N-氧化反应,可以制备式(VI)中间体硝酮类。
所述N-氧化反应还可以在式(XII)喹啉的前体上进行。
假设式(XII)中间体在体内通过式(VI)中间体被代谢为式(I)化合物。因此,式(XII)和(VI)中间体可以用作式(I)化合物的前药。
式(I)化合物和某些中间体在其结构中具有至少一个立体中心。该立体中心可以以R或S构型存在。
如上文所述方法制备的式(I)化合物一般为对映异构体的外消旋混合物,它们可以通过本领域已知的拆分方法彼此分离。式(I)的外消旋化合物还可以通过与合适的手性酸反应,转化为相应的非对映异构的盐形式。随后分离所述非对映异构的盐形式,例如通过选择或分级结晶并且用碱从中释放出对映异构体。分离式(I)化合物对映异构形式的另一种方法是使用手性固定相的液相色谱。所述纯立体化学异构形式还可以由相应的合适反应起始物的纯立体化学异构形式衍生而来,条件是反应是立体有择地发生。优选的是,如果需要特定的立体异构体,通过立体有择的制备方法合成所述化合物。这些方法优选使用对映体纯的起始物。
本发明提供了式(I)化合物用于抑制平滑肌细胞增殖的方法,如在药理学实例C.1中所述。
因此,式(I)化合物可以用于制备抑制平滑肌细胞增殖的药物,因此也用于制备治疗血管增殖疾病如动脉硬化和再狭窄的药物。
在文献中已经揭示了平滑肌细胞增殖后的机理涉及失去正常的细胞生长调节,这是一种ras蛋白起重要作用的方法。由此提示,具有法呢基转移酶抑制性质的化合物可以用于预防血管损伤后的平滑肌细胞增殖(Indofi等,天然药物(Nature medicine),1,541-545(1995)和Irani等,生物化学与生理学研究通讯(Biochemical and biophysicalresearch Communications),202,1252-1258,(1994))。
动脉硬化症的特征在于脂肪物质沉积于动脉内层以及动脉内层纤维变性。
再狭窄是管壁受到外伤之后患者的管状通道变窄。这可以由非控制的新内膜组织的细胞增殖引起,这通常是由于采用血管再造技术如隐静脉分流移植、动脉内膜切除术、经皮经管腔冠状血管成形术(PTCA)等。再狭窄是指动脉腔狭窄的恶化或者复发,其特征是动脉壁细胞的增生。在此方面,再狭窄明显不同于由动脉硬化斑造成的动脉闭合以及血栓引起的闭合。
再狭窄不仅仅限于冠状动脉。它还可发生于外周血管系统。
血管成形术是一种将动脉硬化斑和/或血栓阻塞的动脉机械清除的技术。这种阻塞或阻滞的动脉影响适当的血液流动。血管成形术相对于常规的其他手术方法如冠状分流术而言具有更低的介入性并且创伤最小,这种方法作为扩张和清理动脉的手段已经被普遍接受。在常规的血管成形术中,将梢尖的小球导管通入动脉中,通常使用导线或导管,在其中可以将萎陷的球置于一个以上的动脉狭窄点。在阻塞部位放置时,使小球膨胀,因而使阻塞展开和/或破裂并且使动脉腔(口)扩张。将球放气并从动脉中取出后,动脉的内径通常会增大,使得血流恢复。这些球和导管装置通常被称作冠状球扩张导管。但是,所述血管成形术面临着局部和系统血栓栓塞作用、动脉壁撕裂和再狭窄的危险。
气囊血管成形术后再狭窄也称作“经皮经管腔冠状血管成形术再狭窄”,其特征是由于气囊损伤后内膜中的平滑肌细胞层新内膜形成导致动脉中阻塞再形成。
因此,本发明提供了治疗温血动物血管增殖疾病如,动脉粥样硬化或再狭窄的方法,该方法包括给所述温血动物施用预防或治疗有效量的式(I)化合物。
本发明还提供了抑制温血动物平滑肌细胞增殖的方法,该方法包括给所述温血动物施用预防或治疗有效量的式(I)化合物。
在气囊血管成形术之后可以进行已知被称作血管内斯滕特氏印模膏(stenting)的机械/外科手术,在该手术中,在血管成形术之后的动脉中放置可扩张的金属套管或支架,即斯滕特氏印模膏。然而,在插入斯滕特氏印模膏之后,一种被称作“冠状动脉斯滕特氏印模膏再狭窄”的疾病可能会发生,因而由于内膜中的平滑肌细胞层新内膜形成导致动脉中阻塞再形成。因此,用含有式(I)化合物的涂覆材料包裹或覆盖所述斯滕特氏印模膏以抑制平滑肌细胞增殖是有利的。所以,一方面,本发明还提供了用含有预防、治疗或减少平滑肌细胞增殖有效量的式(I)化合物的涂覆材料包裹或覆盖的斯滕特氏印模膏。市售的斯滕特氏印模膏是例如气囊可扩张的斯滕特氏印模膏,例如Palmaz-SchatzTM斯滕特氏印模膏和Gianturco-RoubinTM斯滕特氏印模膏,以及自膨胀斯滕特氏印模膏例如GianturcoTM可膨胀导线斯滕特氏印模膏和WallstentTM,其它斯滕特氏印模膏是Palmaz-Schatz CrownTM、Cross-FlexTM、ACS Multi-LinkTM、NirTM、Micro StentTM和WiktorTM。
一方面,本发明还涉及用含有预防、治疗或减少平滑肌细胞增殖有效量的式(I)化合物的涂覆材料包裹或覆盖的导管或其它经腔装置。
斯滕特氏印模膏的金属表面可以用多种方式涂覆。该表面可以采用两步法制备,包括通常通过金属氧化物使具有胺活性位点的有机硅烷于金属膜表面共价连结。还可以使用表面具有乙烯基官能侧基的有机硅烷。然后,可以将生物相容的涂覆材料共价连结于有机硅烷涂层。
含有式(I)化合物的该涂层还可以用作聚合物前体与式(I)化合物的混合物,该式(I)化合物是细分散或者溶于聚合物溶剂或载体中,之后可将其就地固化。
可以通过用具有较高蒸汽压的蒸发性溶剂浸渍或喷雾以产生所需的粘度和涂层厚度来施用该涂层。该涂层牢固的粘结在斯滕特氏印模膏开放结构的细丝表面,以保护涂覆装置中包线或其它部件的开放晶格性质。
斯滕特氏印模膏涂层的主要组分应该具有弹性。斯滕特氏印模膏涂层优选地是合适的疏水生物稳定的弹性物质,该物质不会降解并且使组织排斥和组织炎性降至最低,以及被毗邻斯滕特氏印模膏植入部位的组织包围。适用于这种涂层的聚合物包括硅酮(例如聚硅氧烷和取代的聚硅氧烷)、聚氨基甲酸酯、一般的热塑性高弹体、乙烯乙酸乙烯酯共聚物、聚烯烃高弹体和EPDM橡胶。
将式(I)化合物负载于斯滕特氏印模膏涂层可以变化。通过改变涂层的厚度、基团的分布、混合的方法、所述式(I)化合物的量以及聚合物材料的交联密度,可以按需获得所需的释放速度。
在例如WO-96/32907、US-5607475、US-5356433、US-5213898、US5049403、US-4807784和US-4565740描述了涂覆斯滕特化印模膏的方法。
斯滕特氏印模膏由生物相容的材料制成,这些材料是例如不锈钢、钽、钛、镍钛金属互化物、金、铂、因钢、铱、银、钨、或者另一种生物相容金属、或者上述金属的合金。不锈钢和钽是特别适用的。所述斯滕特氏印模膏可以用一层或多层生物相容的涂覆材料层涂覆,所述涂覆材料是例如炭、炭纤维、乙酸纤维素、硝酸纤维素、聚硅氧烷、聚对亚苯基二甲基、聚对亚苯基二甲基衍生物、聚对苯二酸乙二酯、聚氨基甲酸酯、聚酰胺、聚酯、聚原酸酯、聚酐、聚醚砜、聚碳酸酯、聚丙烯、高分子量聚乙烯、聚四氟乙烯或者另一种生物相容材料,或者这些共聚物的混合物。聚对亚苯基二甲基既是已知的以对二甲苯为基础并且通过气相聚合形成的聚合物的通用名,也是未取代的这些聚合物的名称。所述一层或多层生物相容材料层含有本发明的式(I)化合物,优选提供有效预防、治疗或减少平滑肌细胞增殖的控制释放的所述式(I)化合物。所述一层或多层生物相容材料层还可以含有生物活性物质例如肝素或另一种凝血酶抑制剂,水蛭素、hirulog、argatroban、D-苯丙氨酰-L-多-L-精氨酰氯甲基酮,或者另一种抗血栓形成剂或其混合物;尿激酶,链激酶,组织纤维蛋白溶酶原活化剂,或者另一种溶解血栓药,或其混合物;纤维蛋白溶解药;血管痉挛抑制剂;钙通道阻滞剂,硝酸盐,氧化氮,氧化氮助催化剂(promotor)或另一种血管舒张药;杀微生物剂或抗生素;阿司匹林,氯苄噻啶,糖蛋白IIb/IIIa抑制剂或另一种表面糖蛋白受体抑制剂,或者另一种抗血小板药;秋水仙素或另一种抗有丝分裂剂,或者另一种微管抑制剂;视网膜样或另一种抗分泌药;细胞松弛素或另一种肌动蛋白抑制剂;脱氧核糖核酸,抗敏核苷酸或另一种分子遗传介入剂;氨甲喋呤或另一种抗代谢或抗增殖药;抗癌化疗药;地塞米松、磷酸地塞米松钠、乙酸地塞米松或者另一种地塞米松衍生物,或者另一种抗炎的甾族或非甾族抗炎药;环孢菌素或另一种免疫抑制剂;唑嘧胺(PDGF拮抗剂),angiopeptin(生长激素拮抗剂),抗生长因子抗体,或者另一种生长因子拮抗剂;多巴胺,甲磺酸溴麦角环肽,甲磺酸硫丙麦角林或另一种多巴胺兴奋剂;巯甲丙脯酸,enalapril或者另一种血管紧张肽转化酶(ACE)抑制剂,抗坏血酸,α-生育酚,超氧化物歧化酶,去铁胺,21-氨基类固醇(lasaroid)或者另一种自由基清除剂;或者上述物质的混合物。
因此,本发明还提供了治疗温血动物血管增殖疾病例如经皮经腔冠状血管成形术再狭窄或者冠状动脉斯滕特氏印模膏再狭窄的方法,该方法包括给所述温血动物施用预防或治疗有效量的式(I)化合物。
所述的具体温血动物是哺乳动物,特别是人。
正如本领域已知的那样,预防或治疗有效量随治疗剂的类型而变化。本领域专业人员知晓如何确定合适治疗剂的预防或治疗有效量。
考虑到其有用的药理学性质,可以将本发明的化合物配制成各种给药目的的药物形式。为了制备本发明的药物组合物,将作为活性成分的碱或酸加成盐形式的有效量的具体化合物与可药用载体充分混合,根据给药所需的制剂形式,所述载体可以有多种形式。这些药物组合物最好是尤其适用于口服、直肠、皮下或非肠道注射给药的单位剂量形式。例如,在制备口服组合物时,如果是口服液体制剂例如悬浮液、糖浆、酏剂和溶液,可以使用任何常用的药物载体,例如水、乙二醇、油类、醇类等;如果是粉末、小丸、胶囊和片剂,可以使用固体载体,例如淀粉、糖、高岭土、润滑剂、粘合剂和崩解剂等。由于便于给药,片剂和胶囊代表最优选的口服剂量单位形式,在这种情况下,可以使用各种固体药物载体。对于非肠道组合物,载体通常包括至少大部分的无菌水,尽管可以包括其它成分例如助溶的物质。可以制备可注射溶液,例如其中载体含有盐水溶液,葡萄糖溶液或盐水与葡萄糖溶液的混合物。也可以制备可注射的悬浮液,在这种情况下,可以使用合适的液体载体、悬浮剂等。在适用于皮下给药的组合物中,载体任意地含有渗透增强剂和/或合适的湿润剂,它们任意地与任何性质的最小比例的合适添加剂混合,所述添加剂不会对皮肤引起明显的有害影响。所述添加剂便于对皮肤给药和/或有助于制备所需的组合物。这些组合物可以以各种方式给药,例如透皮贴剂、点涂剂、油膏剂。特别有利的是将上述药物组合物配制成单位剂量形式以便于给药和剂量一致。本说明书和权利要求书中所用剂量单位形式是指适于用作单位剂型的可物理分离的单位,每一单位含有预定量的、经计算可产生所需治疗作用的活性成分和所需的药物载体。这些剂量单位形式是片剂(包括刻痕片或包衣片)、胶囊、小丸、粉包、糯米纸囊剂、可注射溶液或悬浮液、茶匙剂(teaspoonfuls)、餐匙剂(tablespoonfuls)等,及其分离的多剂量包装。

C.1.平滑肌细胞增殖的抑制作用
在标准组织培养条件下生长的人肺动脉平滑肌细胞(PASMC)、人冠状动脉平滑肌细胞(CASMC)和大鼠A10动脉平滑肌细胞中对本发明化合物的作用进行研究。CASMC和PASMC细胞培养物购自Clonetics(San Diego,CA)。A10平滑肌细胞购自美国典型培养物保藏中心(ATCC,Bethesda,MD)。在6孔塑料簇状组织培养皿中,以每孔50,000个细胞的初始细胞密度将细胞接种于3.0毫升完全生长培养基中。将实验化合物溶解在二甲基亚砜(DMSO)中,并以3μl的体积加至每孔中,以生成所需的所述实验化合物的浓度(5、10、50、100和500nM最终浓度)。将细胞培养6天。在第4天,向细胞培养物中加入新鲜的培养基和含有实验化合物的新鲜溶液。在第6天,吸除生长培养基。通过在1.0ml胰岛素-EDTA溶液中进行胰蛋白酶化分离细胞。将细胞悬浮液转入20毫升等渗稀释剂中,并用Coulter颗粒计数器对0.5毫升稀释的细胞悬浮液计数。以由DMSO处理的培养物得到的细胞计数为对照,使由实验化合物处理的培养物的细胞计数标准化,并以百分抑制率表示。由抑制数据得到IC50值(实验化合物产生50%细胞增殖抑制作用的浓度)。这些结果汇总在表C.1中。
