Abstract
本发明涉及使用在权利要求1的通式(I)中公开的二芳基胺类治疗慢性疼痛的方法。
Description
技术背景
本发明特征在于使用MEK抑制剂治疗慢性疼痛的方法。慢性疼痛包括神经病性疼痛,和慢性炎症疼痛。
在神经传输中的任何异常都会干扰神经信号,进而在脑内不正常地解释,引起神经病性疼痛。神经病性疼痛可以是,例如,深度疼痛,烧灼感,或对触觉的过敏症。与神经病性疼痛有关的疾病或症状不受限制地包括,糖尿病性神经病,灼性神经痛,神经丛抽出术,神经瘤,脉管炎,挤压伤,病毒感染(例如,疱疹病毒传染或HIV),缩窄伤害,组织伤害,从周围到中枢神经系统的神经伤害,截肢,甲状腺功能减退,尿毒症,慢性醇中毒,手术后疼痛,关节炎,背痛,和维生素缺乏。
传染如带状疱疹能够引起神经炎症和产生带状疱疹后神经痛,位于病毒感染区域中的慢性灼烧。痛觉过敏是当已经有害的刺激变成更痛苦时,和异常性疼痛,当以前无害的刺激变成痛苦(如衣服或微风的接触)时。反射交感性营养不良伴随有肿胀和发汗或在局部血流中的变化、组织萎缩或骨质疏松症。灼性神经痛,包括严重的烧灼痛和肿胀,发汗,和在血流上的变化,接着会造成主要神经如坐骨神经的伤害或疾病。一些类型的慢性下腰痛能够有神经病性的成分(例如,坐骨神经痛,后脊髓灰质炎和CPRM)。神经病性疼痛也可以由癌症或化学疗法诱导。
神经病性疼痛现在用抗惊厥药例如卡马西平和抗抑郁药例如阿米替林治疗。NSAIDS和类鸦片物质一般有较少的作用(Fields等,1994Textbook of Pain,p 991-996(出版:Churchill Livingstone),James & Page 1994;J.Am.Pediatr.Med.Assoc,8:439-447,Galer,1995 Neurology 45 S17-S25。已经用加巴喷丁治疗的神经病症状包括:带状疱疹后神经痛,后脊髓灰质炎,CPRM,HIV-相关的神经病,三叉神经痛,和反射交感性营养不良(RSD)。
消炎药剂的通常较弱的效力预示着慢性疼痛的机理与痛觉过敏不太相关。

详细说明
这里所公开的化合物具有药物活性,例如它们抑制MEK。MEK酶类是在例如免疫调节、炎症和增生性疾病如癌症和再狭窄中牵涉的双重特异性激酶。
增生性疾病是由细胞内信号系统中的缺陷,或某些蛋白质的信号转导机理所引起的。这些缺陷包括在固有活性上或在信号级联中一种或多种信号蛋白质的细胞浓度上的变化。该细胞可产生结合于它本身的受体的增长因子,导致自分泌环,继续刺激增生。细胞内信号蛋白质的变异或过度表达能够导致细胞内假性致有丝分裂信号。在编码蛋白质(称为Ras)的基因中发生了最常见的一些变异,该蛋白质是一种当结合于GTP时被活化而当结合于GDP时则失活的G蛋白质。上述的生长因子受体和许多其它的致有丝分裂受体,但被活化时,导致Ras从GDP结合状态转化成GTP结合状态。这一信号是大多数细胞类型中增生的绝对先决条件。在这些信号系统中,尤其在Ras-GTP复合物的减活中的缺陷是癌症中常见的,而且导致在Ras之下的信号级联被慢性活化。
活化的Ras进而导致丝氨酸/苏氨酸激酶的级联的活化。已知对于其本身的活化需要活性Ras-GTP的各组激酶中的一种是Raf族。这些进而活化MEK(例如MEK1和MEK2),它然后活化MAP激酶,ERK(ERK1和ERK2)。由促分裂原使MAP激酶的活化似乎对于增生是必要的;这一激酶的组成性的活化足以诱导细胞的转化。下游Ras信号传输的阻断,例如通过使用显性失活Raf-1蛋白质,能够完全抑制有丝分裂发生,不论是从细胞表面受体还是从致癌的Ras突变体诱导的。虽然Ras它本身不是蛋白激酶,但是它参与Raf及其它激酶的活化,很可能通过磷酸化机理。一旦被活化,Raf和其它激酶使两个紧密相邻的丝氨酸残基-S218和S222(对于MEK-1)上的MEK发生磷酸化,这是作为激酶的MEK的活化的先决条件。MEK进而使在被单个氨基酸分隔的酪氨酸(Y185)和苏氨酸残基(T183)两者上的MAP激酶发生磷酸化。
这种双磷酸化使MAP激酶活化了至少100倍。活化的MAP激酶然后催化大量蛋白质的磷酸化,其中包括几种转录因子和其它的激酶。许多这些MAP激酶磷酸化对于目标蛋白质是致有丝分裂地活化,如激酶,转录因子,或另外的细胞蛋白质。除了Raf-1和MEKK之外,其它的激酶会活化MEK,而MEK本身好象是信号整合激酶。目前的理解是MEK对于MAP激酶的磷酸化具有高度专一性。事实上,除了MAP激酶ERK以外没有别的MEK的底物目前已得到验证,而且MEK不会根据MAP激酶磷酸化序列来使肽发生磷酸化,或甚至使变性的MAP激酶发生磷酸化。MEK也看起来与MAP激酶在磷酸化它之前强力缔合,这预示着MAP激酶利用MEK来磷酸化可能需要在前的在两个蛋白质之间的强相互作用。这一需要和MEK的不寻常的特异性都预示了在它对于其它蛋白激酶的作用机理上的足够不同,可以发现可能通过变构机理而不是通过ATP结合部位的惯常阻断来操作的、MEK的选择性抑制剂。
通过用von Frey毛发评定静态异常性疼痛(static allodynia),在神经病性疼痛的两个动物模型中考察研究了MEK抑制剂PD 198306的效果。
PD 198306(3-30mg/kg)的口服在坐骨神经的慢性缩窄伤害(CCI)模型中没有作用。然而,在反复给药之后(在2天中3次剂量),它在糖尿病性神经病模型(链佐星)中具有暂时性效果。这可归因于由这些动物体内的糖尿病症状所诱发的血脑屏障的障碍,因此允许该化合物的中枢性作用。PD 198306(1-30μg)以分别3和10μg的最低有效剂量(MED)的鞘内给药将会依赖于剂量来阻断在神经病性疼痛的链佐星和CCI两模型中的静态异常性疼痛。所使用的最高剂量(30μg)总体上阻断静态异常性疼痛的维持达到至多1小时。在比鞘内显示有效性的那一剂量(30μg/10μl)高100倍的剂量下,PD 198306的足底内给药(3mg/100μl)对于在任何一种神经病性疼痛模型中的静态异常性疼痛没有作用。这一发现证实了在系统性给药之后见到的效果的缺乏,提示了该化合物的起作用的中心位置。
从这一研究我们能够建议MEK抑制剂用作慢性疼痛的有潜力的新治疗工具。对未来的脑渗透剂MEK抑制剂的潜在副作用(尤其与记忆力有关)的研究将显示这一新型的一类化合物在治疗疼痛上的治疗前景。

E.实施例
生物学实施例
实施例1
PD 198306对链佐星诱导的静态异常性疼痛的影响
动物
雄性Sprague Dawley大鼠(250-300g),从Bantin andKingman(Hull,U.K.)获得,分每组三只进行圈养。所有的动物保持在12h光/黑暗周期(在07h 00min照明开始)下,食物和水不限量。全部的实验是由没有看见药物治疗的观察者来进行。
在大鼠体内糖尿病的发展
按照前面所述(Courteix等人,1993),通过单次腹膜内注射链佐星(50mg/kg),在大鼠体内诱发糖尿病。
静态异常性疼痛的评价
使用Semmes-Weinstein von Frey毛发(Stoelting,Illinois,U.S.A.)测量机械过敏性。将动物放入有铁丝网底的笼中,允许触碰它们的爪的下侧。在开始实验之前让动物习惯于这一环境。通过用vonFrey毛发以递增顺序的力(0.7,1.2,1.5,2,3.6,5.5,8.5,11.8,15.1和29g)触碰动物右后爪的足底表面达6秒来测试机械过敏性。一旦退缩反应已完成,该爪重新进行试验,用下一个递减力量的vonFrey毛发开始试验,直到不再有响应为止。最高29g的力提升了该爪以及引起了响应,因此表示该截止点。为了引起响应所需要的最低量的力被记录为该爪退缩阈值(PWT),按g计。
药剂
在Parke-Davis(Ann Arbor,Ml,USA)合成了PD 198306 [N-环丙基甲氧基-3,4,5-三氟-2-(4-碘-2-甲基-苯基氨基)-苯甲酰胺]和CI-1008(pregabalin)。将PD 198306悬浮在聚乙二醇化合物(cremophor)∶乙醇∶水(1∶1∶8)媒介物中。将Pregabalin溶于水。两种化合物都口服。链佐星(Aldrich,UK)溶于0.9%w/v NaCl中并且腹膜内给药。以1 ml/kg的体积来施用药剂。
统计学
该静态异常性疼痛数据是使用用于非参数结果的Kruskall-Wallis ANOVA来分析,当显著时,接着进行Mann-Whitney的t检验。
实验原始记录
静态异常性疼痛是在口服PD 198306(30mg/kg,p.o.),媒介物(聚乙二醇化合物∶乙醇∶水,1∶1∶8)或pregabalin(30mg/kg,p.o.)(试验)之前(基线,BL)和在口服之后1小时用von Frey毛发评价的。这些动物在第二天再一次施用同样的化合物,在早上和下午。静态异常性疼痛仅仅在下午施用之前和在施用之后1小时来评价,为的是最大程度减少动物对这些试验条件的习惯化。用pregabalin治疗的动物在早上施用时接受水,为的是避免对反复施用的化合物的耐受性的潜在发展。

结果
单次施用pregabalin(30mg/kg,p.o.)显著地在给药之后的1小时阻断了链佐星诱发的静态异常性疼痛。相反,在给药之后的1小时,单次施用PD 198306(30mg/kg,p.o)对链佐星诱导的静态异常性疼痛没有任何影响(见下文)。然而,在第二天两次以上施用该化合物之后,在第三次施用之后它显著地阻断了链佐星诱导的静态异常性疼痛。在随后的几天该效果已经消失(参见图1)。

按照前面所述(Courteix等人,1993),通过单次腹膜内注射链佐星(50mg/kg),在大鼠体内诱发糖尿病。
大鼠体内慢性缩窄伤害的形成
动物是在外科处理过程中经鼻锥使用2%异氟烷1∶4 O2/N2O混合物来实施麻醉。该坐骨神经按照以前Bennett和Xie,1988所描述的方式来结扎。在整个操作程序当中将动物放置在调温毯上。在外科准备之后,利用钝器解剖开股二头肌,在股的中段暴露普通的坐骨神经。邻近该坐骨三叉处,将大约7mm的神经从粘附组织上剥离下来,用4根结扎线(4-0丝)以大约1mm间隔松散地缠绕它系好。切口分层缝合,伤口用局部抗生素处理。
鞘内注射
通过在简单的异氟烷麻醉下暴露大鼠的脊柱,使用100μl汉密尔顿注射器以10μl的体积经鞘内施用PD 198306和pregabalin。用10mm长27号针头注入到在腰区5-6之间的鞘内空间中。如果有尾部摇晃响应,则穿透被判断是成功的。伤口用自动小夹封合,在注射之后的2-3分钟内鼠看上去完全唤醒。
静态异常性疼痛的评价
使用Semmes-Weinstein von Frey毛发(Stoelting,Illinois,U.S.A.)测量机械过敏性。将动物放入有铁丝网底的笼中,允许触碰它们的爪的下侧。在开始实验之前让动物习惯于这一环境。通过用vonFrey毛发以递增顺序的力(0.7,1.2,1.5,2,3.6,5.5,8.5,11.8,15.1和29g)触碰动物右后爪的足底表面达6秒来测试机械过敏性。一旦退缩反应已确定,该爪重新进行试验,用下一个递减力量的vonFrey毛发开始试验,直到不再有响应为止。最高29g的力提升了该爪以及引起了响应,因此表示该截止点。为了引起响应所需要的最低量的力被记录为该爪退缩阈值(PWT),按g计。实验原始记录
静态异常性疼痛是在PD 198306(1-30μg,i.t.),媒介物(聚乙二醇化合物∶乙醇∶水,1∶1∶8)或pregabalin(10μg,i.t.)的鞘内或足底内给药之前(基线,BL)和在其之后的0.5h、1h和2h时,用von Frey毛发来评价。对于口服实验,静态异常性疼痛是在口服PD 198306(3-30mg/kg,p.o.),媒介物(聚乙二醇化合物∶乙醇∶水,1∶1∶8)或pregabalin(30mg/kg,p.o.)之前(基线,BL)和之后1小时用von Frey毛发评价。这些动物在第二天再一次施用同样的化合物,在早上和下午。静态异常性疼痛是在早上给药之前和之后1h来分析。在下午,静态异常性疼痛是对于链佐星治疗的动物在给药之前,在给药之后1h、2h和3h时来评价。在给药之前,在给药之后1h和2h时,评价CCI动物。所使用的药剂
PD 198306和pregabalin是在Parke-Davis(Ann Arbor,MI,USA)合成的。PD 198306被悬浮在聚乙二醇化合物∶乙醇∶水(1∶1∶8)媒介物中。将Pregabalin溶于水。两种化合物分别以1ml/kg、10μl和100μl的体积来口服、鞘内施用或足底内施用。链佐星(Aldrich,UK)溶于0.9%w/v NaCl中并且以1ml/kg的体积经过腹膜内给药。统计学
该数据是使用针对非参数的结果的Kruskall-Wallis ANOVA来分析,当显著时,接着进行对于媒介物组的Mann-Whitney的t检验。结果
1.PD 198306对于在系统给药之后静态异常性疼痛的影响
1.1.PD198306对链佐星诱导的静态异常性疼痛的影响
单次施用pregabalin(30mg/kg,p.o.)显著地在给药之后的1小时阻断了链佐星诱发的静态异常性疼痛。相反,在给药之后的1小时,单次施用PD 198306(3-30mg/kg,p.o)对链佐星诱导的静态异常性疼痛没有任何影响(图2)。然而,在第二天再两次施用该化合物之后,在第三次施用之后PD 198306(30mg/kg)显著地阻断了链佐星诱导的静态异常性疼痛达2h(图2)。
1.2.PD 198306对CCI诱导的静态异常性疼痛的影响
单次施用pregabalin(30mg/kg,p.o.)显著地在给药之后的1小时阻断了CCI诱发的静态异常性疼痛。相反,PD 198306(3-30mg/kg,p.o)的单次或多次给药都对CCI诱导的静态异常性疼痛没有任何影响(图3)。
2.PD 198306对于在鞘内给药之后静态异常性疼痛的影响
鞘内给药的PD 198306(1-30μg)剂量-独立地阻断了在链佐星(图4)和CCI动物(图5)体内静态异常性疼痛的维持,MEDs分别为3和10μg。这一抗异常性疼痛效果持续了1h。
3.PD 198306对于在足底内给药之后静态异常性疼痛的影响
PD 198306(30μg)的鞘内给药显著地阻断了在两个神经病性疼痛的模型(图6,7)中的静态异常性疼痛。相反,PD 198306以100倍以上的剂量(3mg/100μl)单次直接施用于爪却对链佐星(图6)或CCI诱导的静态异常性疼痛(图7)没有影响。

其它MEK抑制剂在大鼠的神经病性疼痛模型中的作用摘要
具有不同的结合亲和力的几种MEK抑制剂的效果已经在大鼠的神经病性疼痛的CCI模型中进行了考察,通过用von Frey毛发评价静态异常性疼痛。PD219622或PD297447(30μg)的鞘内给药对异常性疼痛没有显著的效果。这一效果的缺乏反映出该化合物的低亲合性或溶解度。然而,具有较高结合亲合性的PD 254552或PD 184352(30μg)的鞘内给药阻断了静态异常性疼痛在CCI动物体内的维持。该抗异常性疼痛效果仅仅在注射后30min才变明显,因此,短于对于pregabalin(100μg)所观察到的时间。效果的大小对于30μg的PD184352和100μg的pregabalin是相同的。从这一研究可以推断,当鞘内给药时MEK抑制剂在CCI诱导神经病性疼痛的大鼠中发挥出抗异常性疼痛效果,而且该抗异常性疼痛效果与化合物的亲合性有关。
动物和在大鼠体内形成慢性缩窄伤害的方法,注射试验化合物和静态异常性疼痛的评价都与以上实施例2一致。PD219622、PD297447、PD184352、PD254552和pregabalin都通过鞘内给药,对于全部的PD化合物使用30μg的剂量和对于pregabalin使用100μg的剂量。在化合物的鞘内给药之前(基线,BL),在给药之后0.5h、1h和2h用von Frey毛发评价静态异常性疼痛。所使用的药剂
PD297447,PD219622,PD254552,PD184352(CI-1040)和pregabal in是在Parke-Davis(Ann Arbor,MI,USA)合成的。将PD297447,PD219622,PD 254552和PD184352悬浮于聚乙二醇化合物∶乙醇∶水(1∶1∶8)媒介物中。将Pregabalin溶于水中。全部的化合物以10μl体积鞘内给药。统计学
该数据是使用针对非参数结果的Kruskall-Wallis ANOVA来分析,当显著时,接着进行对于媒介物组的Mann-Whitney的t检验。结果
PD297447或PD219622(30μg)的鞘内给药对异常性疼痛没有显著的影响。这一效果的缺乏可能反映了化合物的低亲合性(分别965nM和100nM)。然而,PD 184352或PD 254552(30μg)的鞘内给药阻断了在CCI动物体内静态异常性疼痛的维持(参见图8)。这些化合物具有较高的亲合性(分别2和5nM)。该抗异常性疼痛效果仅仅在注射后30min才变明显,因此,短于对于pregabalin(100μg)所观察到的时间。效果的大小对于30μg的PD 184352和100μg的pregabalin是相似的。
所获得的结果表明,当鞘内给药时MEK抑制剂在CCI诱导神经病性疼痛的大鼠中发挥出抗异常性疼痛效果,而且该抗异常性疼痛效果与化合物的亲合性有关。
