相关申请的交叉引用
本申请主张2006年10月2日递交的美国临时申请No.60/848,761的权益。前述申请的内容在此通过整体引用引入本文。
背景技术
由大麻(Cannabis sativa)提炼出的大麻素已于几世纪以来被用作治疗药物的一种。比如,被用来作止痛、肌肉放松、刺激食欲及抗惊厥用。近来的研究更指出其具有治疗癌症、缓和慢性发炎疾病,如风湿病及多发性硬化症的功效。
大麻素的作用受至少两种大麻素受体CB1及CB2受体的介导,此两者都属G蛋白偶联受体(GPCR)超家族。CB1受体主要表现于脑部以调控抑制递质释放,而CB2受体主要表现于免疫细胞以调控免疫反应。相关资料见Matsuda等人,Nature(1990)346:561及Munro等人,Nature(1993)365:61。
相较于其它GPCRs,CB1受体具有高量表达的特征。在中枢神经系统中,其被高量表达于脑皮层、海马体、基底核、及小脑中,但于下视丘及脊随中却呈现低量表达。如见:Howlett等人,Pharmacol Rev(2002)54:161。其功能可影响到许多神经学及心理学现象,如:情绪、食欲、呕吐控制、记忆、空间协调、肌肉张力、及痛觉缺失。如见Goutopoulos等人,PharmacolTher(2002)95:103。除了中枢神经系统,其也表现于许多周边器官,如:肠、心脏、肺脏、子宫、卵巢、睪丸及扁桃腺。如见:Galiègue等人,Eur JBiochem(1995)232:54。
CB2受体其44%与CB1受体相同,而其中有68%是在跨膜区相同。相关资料见Munro等人,Nature(1993)365:61。相较于CB1受体,CB2受体的高量表达较被限制于脾脏及扁桃腺,而在肺脏、子宫、胰脏、骨髓、及胸腺中则呈低量表达。在免疫细胞中,B细胞所表达的CB2受体为最高量,其次依序为自然杀伤细胞(natural killer cells)、单核细胞(monocytes)、中性粒细胞(polymorphonuclear neutrophil)、及T淋巴细胞。相关资料见Galiègue等人,Eur J Biochem(1995)232:54。CB2受体活化已被证实对于与神经系统退变性疾病(如阿兹海默症)相关的炎症具有止痛效果,且也扮演维持骨质密度及改善动脉粥样硬化的角色。相关资料见Malan等人,Pain(2001)93:239;Benito等人,J Neurosci(2003)23:11136;Ibrahim等人,Proc Natl Acad Sci USA(2003)100:10529;Idris等人,Nat Med(2005)11:774;以及Steffens等人,Nature(2005)434:782。

特别地,如上流程图1所示,首先,包含酮基的噻吩化合物(例如化合物A)可在锂盐存在的环境下与草酸酯化合物(例如草酸二乙酯,diethyloxalate)进行克莱森酯缩合反应(Claisen condensation reaction),以形成含酯基的1,3-二酮化合物(例如化合物B)。该1,3-二酮化合物可接着与联胺(hydrazine)反应,以形成腙化合物(hydrazone),其不需再经纯化,可在醋酸回流下进行分子内环化反应,以形成含有酯基的吡唑(pyrazole)化合物(例如化合物C)。该吡唑化合物可与溶于乙腈的N-溴丁二酰亚胺(N-bromosuccinimide,NBS)反应,以形成在噻吩环的第5位置含溴的化合物(例如化合物D)。通过与经取代的硼酸或炔烃反应,该溴基可被置换为烯基或炔基。该化合物上形成的酯基(例如化合物E)可藉由加入碱而被水解形成羧酸,而该羧酸可接着与亚硫酰氯(SOCl2)反应形成氯化酰基团,以获得氯化酰化合物(例如化合物F)。该氯化酰化合物可与不同胺类化合物反应形成本发明的某些化合物(例如化合物1-11及化合物30-38)。
上述流程图1中的中间产物可经不同方式的修饰而得到本发明的其它化合物。下流程图2为一说明范例:

用于口服给药的组合物可为任何一种口服可接受的剂型,形式包括胶囊、锭片、乳化剂与液状悬浮液、分散剂与溶剂。以锭片为例,一般所使用的载体为乳糖或是玉米淀粉。润滑剂(如硬脂酸镁)也常被添入其中。以口服胶囊给药形式而言,有效的稀释液包括乳糖与干燥玉米淀粉。当以液状悬浮液或乳化剂经口给药时,活性物质可悬浮或是溶解于结合乳化剂或悬浮剂的油状界面中。如果需要,可添加适度的甜味剂,风味剂或是色素。
鼻用气化喷雾剂或吸入剂组合物可根据医药制剂领域公知的技术进行制备。例如,此组合物可制备于生理食盐水中,应用苯甲醇(benzyl alcohol)或其它适合的防腐剂、增强生物可利用性的促吸收剂、碳氟化合物、和/或其它本领域已知的溶解剂或分散剂。
包含一种或多种活性噻吩化合物的组合物也可以栓剂方式进行直肠给药。
医药组合物的载体必须是“可接受的”,即其必须与组合物的活性主成份兼容(优选具有稳定活性主成份的功能),并且不能对被治疗的受试者造成伤害。一种或多种溶解剂可作为递送活性噻吩化合物的医药赋形剂。其它载体举例包括胶质氧化硅、硬脂酸镁、纤维素、月桂硫酸钠与D&C Yellow # 10。

实施例39、体外试验
本发明的38个测试化合物对于CB1及CB2受体的亲合力是以体外竞争性放射配基受体结合分析方法作测试。本方法通过区分各化合物对受体放射配基的取代力来区别其结合力。具有较放射配基高的受体亲合力的化合物会取代配基与受体结合,而较放射配基低或是无亲合力的化合物则无法取代配基。放射线的读数可用作进一步受体结合作用的分析,并协助预测其测试化合物的药物活性。
此试验分别以雄性Sprague-Dawley大鼠的脑及脾脏萃取物作为CB1及CB2受体来源。使用净重175~200g的雄性Sprague-Dawley大鼠,并于依标准状态下自由供给食物及水作饲养。使用头颈脱臼处死法(cervical dislocation)将动物宰杀。并将含小脑的脑部及脾脏切除下来。将切下来的脑部及脾脏组织分别以Polytron手握式均质机,于加入10体积份的冰冷缓冲液A(50mM三羟甲基氨基甲烷缓冲液(Tris),5mM MgCl2,2.5mM乙二胺四乙酸(EDTA),pH7.4,10%蔗糖)中,藉由蛋白酶抑制剂进行均质化。以2000xg、4℃状态离心该均浆15分钟。再以43000xg、4℃状态离心悬浮物30分钟。且将最后颗粒物再次悬浮于缓冲溶液A中,并于-80℃储存。以Bio-Rad Laboratories,Inc.,Hercules,CA手册内提及的Bradford法测定纯化膜的蛋白质浓度。
受体结合试验中,0.2~8μg膜是以0.75nM[3H]CP55,940及测试化合物于培养缓冲液(50mM Tris-HCl,5mM MgCl2,1mM EDTA,0.3%BSA,pH 7.4)中培养。非特异性结合值是以1μM的CP55,940测得。将混合物置于Multiscreen微孔板(Millipore,Billerica,MA)中,于30℃下培养1.5小时。培养结束后,以Manifold过滤系统终止作用,并以冰冷洗涤缓冲液(50mM Tris,pH 7.4,0.25%BSA)冲洗四次。以Topcount(Perkin Elmer Inc.)测定滤纸上的放射值。计算抑制50%[3H]CP55,940结合所需的化合物浓度,以获得IC50值。
以DELFIA GTP-结合试剂盒(Perkin Elmer Inc.,Boston,MA)测试每一测试化合物的功效。DELFIA GTP-结合测定是时间分辨荧光分析法,其藉由激动剂使G蛋白亚基进行GDP-GTP交换,进而活化G蛋白偶联受体。该方法是以Eu-GTP观察G蛋白的激动剂依赖性活化现象。以CP55,940激活CB1受体会导致G蛋白的α亚基上的GDP被GTP取代。GTP-Gα复合物代表G蛋白的活化型态。Eu-GTP(不可水解的GTP类似物)可用来定量活化的G蛋白量(Peltonen等人,Eur.J.Pharmacol.(1998)355:275)。
将表达人类CB1的HEK293细胞膜再次悬浮于测定缓冲液(50mM HEPES,pH 7.4,100mM NaCl,100g/ml皂素,5mM MgCl2,2M GDP,0.5%BSA)中。于AcroPlate(Pall Life Sciences,Ann Arbor,MI)的每一孔中加入等量样本(4μg蛋白质/孔)。加入测试化合物(于0.1%DMSO中不同浓度)及CP55,940(20nM于测定缓冲液中)后,将测定板置于暗处,并于30℃下轻摇60分钟进行培养。接着,于每一孔中加入Eu-GTP,且将测定板置于暗处,并于30℃培养35分钟。最后,以测定试剂盒所提供的洗涤液,洗涤测定板四次,以终止作用。利用多功能微量盘分析仪(Victor 2multi-label reader)测得荧光信号,进而鉴定Eu-GTP的结合量。藉由非线性回归(Prism;GraphPad,San Diego,CA)的浓度变化曲线获得每一化合物的IC50值(即,抑制50%的CP55,940-激活Eu-GTP结合)。
在CB1受体结合试验和/或CB2受体结合试验中发现所有测试化合物的IC50值都介于0.1nM与20μM之间。Eu-GTP结合试验也可作为指标,其测试结果与上述放射配基受体结合分析的测试结果相符。
