许多不同的取代基选择业已在上文给出并且按照这些取代基选择可以得到本发明的化合物,这些化合物要比那些其中没有采用这些具体取代基选择的化合物更加优选。然而,这些取代基优选一般是独立地,尽管一些选择相互排斥,并且根据一个以上的这些选择可以得到比其中只采用较少这些取代基选择的化合物更加可取的化合物。本发明的化合物可以通过下面合成路线中所示的方法制备。
制备这些化合物所用的起始原料和试剂或者购自商业供应商例如Aldrich Chemical Co.,(Milwaukee,WI)、Bachem(Torrance,CA)或Sigma(St.Louis,MO)、Lancaster Synthesis(Pelham,N.C.)、Maybridge Chemical Co.LTD(Cornwall,United Kingdom)或者通过所属领域技术人员已知的方法按照文献Fieser和Fieser的《有机合成试剂》1-17卷(John Wiley和Sons,1991);Rodd的《碳化合物的化学》,1-5卷和增补(Elsevier Science Publishers,1989);《有机反应》,1-40卷(John Wiley和Sons,1991);March的《高等有机化学》(John Wiley和Sons,4th Edition)和Larock的《综合有机转化》(ComprehensiveOrganic Transforma tions)(VCH Publishers Inc.,1989)中提供的规程制备。这些反应路线仅仅举例说明一些方法,通过这些方法可以合成本发明的化合物,并且对这些反应路线可以进行多种改进并且参考本文内容建议给所属领域的技术人员。
反应的起始原料和中间体如果需要可以用常规技术分离和纯化,包括但不限于过滤、蒸馏、结晶、色谱等。此类物质可以用常规方式描述其特征,包括物理常数和光谱数据。
除非另外作出相反说明,在此所述的反应是在常压、约-78℃至约150℃的温度下,优选0℃至约125℃和首选约室温(常温)如20℃下进行。
反应路线A-H描述了制备式(I)的化合物的方法。
一名所属领域的技术人员应该懂得基团R1、R2、R3、A和B可以以被保护形式存在于反应路线的任意点并且在适当接合处脱除。
反应路线A描述了式(I)的化合物的合成,其中X和Y是CH和R1、R2、R3、A和B如发明概述中定义。
反应路线A
在步骤1中,式1的苯基磺酰基化合物(其中Z是适当的离去基团例如氟或溴)与式2的一取代的胺(其中R1如发明概述中定义或其被保护前体)的反应生成式3的4-氨基苯基磺酰基化合物。该反应是在高温下、优选50-80℃下和在碱例如碳酸钾、三乙胺等的存在下进行。
适合该反应的溶剂是极性非质子溶剂例如DMF、DMSO、HMPA等。通常,式1的化合物可以商购或可以由所属领域普通技术人员轻易合成。
式(I)的化合物可以从式3的化合物、通过任意下面三个步骤制备:步骤2a、2b或2c。
如步骤2a所示,可以从式3的化合物通过还原性胺化来制备式(I)的化合物。化合物3与式4a的醛(其中B如发明概述中定义或其被保护前体)和适当的还原剂(例如氢化物还原剂例如NaBH(OAc)3)的反应生成式(I)的化合物(其中A是CH2)。适合该反应的溶剂是卤代烃,例如二氯甲烷、二氯乙烷等。参见,例如实施例3。
或者,如步骤2b所示,式(I)的化合物可以从式3的化合物通过直接亲核性烷基化作用来制备。化合物3与式4b的化合物(其中B和A如发明概述中定义或其被保护前体并且Z是适当的离去基团例如溴和氯)的反应生成式(I)的化合物。该反应是在碱例如氢化钠的存在下进行。适合该反应的溶剂是极性非质子溶剂例如DMF、DMSO、HMPA等。这个反应是在约室温-70℃下进行。参见例如实施例2和4。
或者,如步骤2c中所示,式(I)的化合物可以从式3的化合物通过酰化/还原作用来制备。化合物3与式4c的酰氯或羧酸(其中Z是离去基团,例如氯或-OH并且B如发明概述中定义或其被保护前体)反应。如果式4c的化合物是羧酸,则偶联剂例如DCC也必须存在。这种酰化作用之后是用适当的还原剂(典型地是氢化物还原剂例如LAH、B2H6、BH3DMS等)还原得到式(I)的化合物(其中A是CH2)。适合该反应的溶剂是极性、无水溶剂例如THF、醚等。
可以向这个通用反应路线A中根据需要添加附加步骤来提供预期的式(I)的化合物。作为附加步骤的实例,可能需要在通过步骤2a、2b或2c制备式(I)的化合物之前保护化合物3的R1中的官能团,随后将该官能团脱保护。例如,可以通过用二碳酸二-叔丁基酯处理3来保护式3的化合物中的胺官能度,随后在步骤2之后脱除叔丁氧基羰基保护基。保护基的实例及其合成应用可以参见T.W.Greerne和P.G.Futs,《有机化学中的保护基》(Wiley,2nd ed.1991)和Harrison与Harrison等的Compendium of Synthetic Organic Methods,Vols.1-8(JohnWiley&Sons.1971-1996)。这些保护/脱保护步骤是所属领域普通技术人员公知的并且无需进一步详述。
通过进一步修饰式(I)的化合物上的官能团也可以获得式(I)的化合物。例如,通过氧化相应的烷硫基烷基化合物可以得到其中R1是烷基磺酰基烷基(例如甲基磺酰基乙基)的式(I)的化合物,其可以经过步骤1通过用相应烷硫基烷基胺处理式1的化合物来制备。
反应路线B描述了通过芳族胺的顺序烷基化合成式(I)的化合物的另一种方法,其中X、Y、R1、R2、R3、A和B如发明概述中定义或其被保护前体,除了R2不是NR13R14之外。
反应路线B

在步骤2中,式7的化合物与式8的烷基化试剂(其中R1如发明概述中定义和Z是适当的离去基团例如溴和氯)反应生成式9的化合物。该反应是在碱例如氢化钠的存在下进行。适合该反应的溶剂是极性、非质子溶剂例如DMF、DMSO、HMPA等。
在步骤3中,式9的化合物用适当氧化剂例如过硫酸钾(OXONE(过硫酸氢钾制剂)TM)、MCPBA等的氧化,生成式(I)的化合物。适合该反应的溶剂是醇,例如甲醇和乙醇。参见例如实施例1。
反应路线C描述了式(I)的化合物的合成,其中X、Y、R2、R3和B如发明概述中定义(除了R2不是NR13R14之外),A是-CH2-和R1是烷基磺酰基烷基。
反应路线C
在反应路线C的步骤1中,式10的芳胺硫化物与式11的醛和适当还原剂(例如NaBH(OAc)3)的反应生成式12的氨基取代的芳族硫化物。
在步骤2中,式12的芳族硫化物与式13的乙烯基砜碱例如氢化钠的存在下反应生成式14的硫化物。适合该反应的溶剂是极性非质子溶剂,例如DMF、DMSO、HMPA等。
在步骤3中,式14的硫化物与适当氧化剂例如过硫酸钾(OXONETM)、MCPBA等的反应,生成式(I)的化合物。适合该反应的溶剂是醇,例如甲醇和乙醇。参见例如实施例5。

本申请还涉及本发明的化合物在制备用于治疗通过施用前列腺素G/H合成酶抑制剂可治疗的疾病的药物中的应用,该药物含有本发明的化合物。
本发明的化合物是前列腺素G/H合酶I和II(COX I和COX II),尤其是COX II的体外抑制剂,因此认为在体内兼具抗炎和镇痛性质。参见例如Goodman和Gilmans’的″治疗剂的药理学基础″,9版,McGraw Hill,New York,1996,27章。所以含有它们的化合物和组合物在哺乳动物、尤其是人体中用作抗炎剂和镇痛剂。发现它们适用于由病症例如类风湿性发热引起的发热、炎症和疼痛,与流感和其他病毒有关的症状、背下部和颈部疼痛、经间痛、头痛、牙痛、扭伤、肌炎、滑膜炎、关节炎(类风湿性关节炎和骨关节炎)、痛风、关节僵硬脊椎炎、粘液囊炎、烧伤或损伤的治疗。它们可以用来抑制类前列腺素引起的平滑肌收缩(例如,经间痛、早产和哮喘)和用来治疗自身免疫性疾病(例如全身性红斑狼疮和I型糖尿病)。
作为前列腺素G/H合酶的抑制剂,本发明的化合物还用于预防和治疗癌症,特别是结肠癌。业已显示COX-2基因表达在人体结肠直肠癌中上调,所述的抑制前列腺素G/H合酶的药物在动物癌模型中显效(Eberhart,C.E.,等,Gastroenterology,107,1183-1188,(1994),和Ara,G.和Teicher,B.A.,Prostaglandins,Leukotrienes andEssential Fatty Acids,54,3-16,(1996))。此外,流行病学证据显示,抑制前列腺素G/H合酶的药物的使用与降低结肠直肠癌危险性之间存在关联(Heath,C.W.Jr.,等,Cancer,74,No.10,2885-8,(1994))。
本发明的化合物还也可以用于治疗和预防阿尔茨海默病。消炎痛,一种前列腺素G/H合酶的抑制剂,业已背证明能够抑制阿尔茨海默患者的认知衰退(Rogers,J.,等.,Neurology,43,1609,(1993))。另外,抑制前列腺素G/H合酶的药物的应用在流行病学上与阿尔茨海默病的延迟发作有关(Breitner,J.C.S.等,Neacrobiology of Aging,16,No.4,523,(1995)和Nettrology,44,2073,(1994))。
可以通过利用如实施例9中详述的放射分析法测定该化合物抑制体外COX I和COX II,尤其是COX II的性能来分析本发明的化合物的抗炎活性。也可以通过体内试验例如大鼠角叉菜胶爪和大鼠空气袋试验(详见实施例10和11)测定。本发明的化合物的镇痛活性可以通过体内试验例如Randall-Selitto试验和大鼠关节炎疼痛模型(如实施例12所述)来测定。
通常,应该以治疗有效量通过任何上述相似用途的药物的可接受给药方式来给予本发明的化合物。本发明的化合物(即活性成分)的精确用量将取决于多种因素,例如被治疗疾病的严重性、对象的年龄和相对健康、所用化合物的效价、甘油的途径和形式以及其他因素。

按照本文的内容,所属领域的普通技术人员部难于确定该治疗有效量。
通常,本发明的化合物是作为药物组合物通过下列任何抑制途径给药:口服、全身性(例如,透皮、鼻内或栓剂),或非肠道(例如,肌肉内、静脉内或皮下)给药。优选的给药方式是采用常规日剂量方案口服,该方案可以根据疾患的程度进行调整。组合物可以是片剂、丸剂、胶囊、半固体、散剂、缓释制剂、溶液、混悬液、酏剂、气溶胶和任何其他适当组合物的形式。
制剂的选择取决于多种因素,例如给药的方式(例如,用于口服给药,优选制剂是片剂、丸剂和胶囊的形式)和该药物的生物利用度。目前,基于可以通过增加表面积提高生物利用度的原理业已开发出特别适合具有低生物利用度的药物的药物制剂,即减小粒度。譬如,美国专利号4,107,288描述了含有粒度范围在10-1,000nm内的微粒的药物制剂,其中活性物质支持在大分子的交联骨架上。美国专利号5,145,684描述了一种药物制剂的制备,其中药物在表明改性剂的存在下被粉碎为毫微颗粒(平均粒度为400nm)并进而分散在液体介质中得到具有非常高生物利用度的药物制剂。
所述的组合物一般含有与至少一种药学可接受赋形剂联合的式(I)的化合物,可接受赋形剂是无毒的,有助于给药,并且对式(I)的化合物的治疗效益没有不良影响。所述的赋形剂可以任何固体、液体、半固体或者在气溶胶组合物的情况中,所属领域技术人员一般会使用气态赋形剂。
固体药物赋形剂包括淀粉、纤维素、滑石、乳糖、蔗糖、明胶、麦芽、稻、面粉、白垩、硅胶、硬脂酸镁、硬脂酸钠、甘油一硬脂酸酯、氯化钠、干脱脂乳等。液体和半固体赋形剂可以选自甘油、丙二醇、水、乙醇和多种油,包括石油、动物、植物和合成来源的那些,例如,花生油、大豆油、矿物油、芝麻油等。优选的液体载体,特别是对于可注射溶液来说,包括水、盐水、葡萄糖水和二醇类。
压缩气体可以用来分散气溶胶形式的本发明化合物。适合这种目的的是惰性气体是氮、二氧化碳等。
其它适用的药物赋形剂家禽制剂描述在Remington’药物科学,E.W.Martin(Mack Publishing Company,18版,1990)编辑。
所述的化合物制剂中的水平可以通过所属领域的技术人员在整个范围内内变化。典型地,以重量百分比(重量%)计,该制剂含有占总制剂约0.01-99.99(重量%)的式(I)的化合物,余量是一种或多种设定的药物赋形剂。更加可取地,所述的化合物是以约1-80(%重量)的水平存在。含有式(I)化合物的代表性药物制剂如实施例8所述。
所属领域的普通技术人员参考本文所述的技术和难溶将不难以确定如果制备适当的制剂。
