Description
相关申请
本申请要求2019年3月11日递交的美国临时专利申请第62/816,441号和2019年11月6日递交的美国临时专利申请第62/931,599号的优先权。上述申请的全部内容通过引证在此全部并入本文。
背景技术
本发明的特征在于用于选择性抑制感觉神经元(伤害性神经元、咳嗽感受神经元和瘙痒感受神经元)的化合物、组合物和方法,以及通过用小分子药物靶向伤害性感受器来治疗神经源性炎症,同时最小化对非伤害性神经元或其他类型的细胞的影响的疗法。根据本发明的方法,小的阳离子药物分子通过大孔受体/离子通道进入感觉神经元的胞内室,所述大孔感受器/离子通道存在于疼痛-神经元、咳嗽感受神经元和瘙痒感受神经元中,但在其他类型的神经元或其他类型的组织中程度较小或根本不存在。
局部麻醉剂,如利多卡因和阿替卡因,通过抑制神经元上的电压依赖性钠通道起作用。这些麻醉剂可以抑制钠离子通道,从而影响所有神经元的兴奋性,而不仅仅是痛觉神经元(伤害性感受神经元)。因此,虽然局部麻醉或区域麻醉的目的是通过阻碍传递伤害性感受神经元的信号来预防疼痛,但局部麻醉药的使用也会产生不想要的或有害的效果,例如由阻碍低阈压和触摸感受神经元引起的全身麻木,由于阻碍运动轴导致的运动障碍和/或瘫痪,以及由于阻碍自主神经纤维而引起的其他并发症。局部麻醉药是相对疏水的分子,通过细胞膜扩散进入钠通道上的阻滞点。这些化合物的带电衍生物是不能渗透细胞膜的,当施加到神经膜的外表面时,对神经细胞的钠通道没有影响,但如果以某种方式引入细胞内,例如通过从用于分离神经元全细胞电生理记录的微吸管扩散,就可以影响阻断钠通道。疼痛-神经元、咳嗽感受神经元和瘙痒感受神经元在表达TRPV1受体/通道方面不同于其他类型的神经元(大多数情况下),TRPV1受体/通道由痛苦的热或辣椒素(辣椒中的辛辣成分)激活。其他类型的通道选择性地表达在各种类型的疼痛-神经元、咳嗽感受神经元和瘙痒感受神经元中,包括但不限于TRPV2-4、TRPA1、TRPM8、ASIC和P2X(2/3)通道。众所周知,一些阳离子小分子,如QX-314,能够通过激活的大孔道进入细胞,如TRPV1。
神经性、炎症性和伤害性疼痛在病因、病理生理、诊断和治疗方面各不相同。伤害性疼痛是由强烈或伤害性刺激激活特定的高阈值外周感觉神经元亚群,即伤害性感受神经元而产生的。它通常是急性的,自我限制的,通过作为潜在的或正在进行的组织损伤的警告来起到保护生物功能的作用。它通常本地化得很好。伤害性疼痛的实施例包括但不限于创伤性或外科疼痛、分娩疼痛、扭伤、骨折、烧伤、肿块、瘀伤、注射、牙科手术、皮肤活检和梗阻。
炎症性疼痛是在存在组织损伤或炎症的情况下发生的疼痛,包括术后(即与由组织创伤(例如,外科切口、解剖、烧伤)或直接神经损伤(例如,神经切断、拉伸或压迫)引起的炎症引起的急性围手术期疼痛相关的疼痛)、创伤后疼痛、关节炎(类风湿;或骨关节炎(即关节软骨逐渐恶化引起的关节疼痛和僵硬;危险因素包括衰老、损伤和肥胖;通常受影响的关节包括手部、手腕、颈部、膝盖、髋部和脊椎),与关节、肌肉和肌腱受损相关的疼痛,如轴性下腰痛(即,一种影响到背部下部的普遍疼痛情况;常见的原因包括肌肉拉伤、脊柱骨折、椎间盘膨出或破裂,以及关节炎),如果出现相关的组织损伤,严重的伤害性疼痛可能会转化为炎症性疼痛。
神经性疼痛是一种常见的慢性、非恶性疼痛,是外周或中枢神经系统损伤或故障的结果,没有保护性的生物学功能。据估计,它将影响到美国人口中的160多万人。神经性疼痛有许多不同的病因,例如,由于创伤、手术、椎间盘突出、脊髓损伤、糖尿病、带状疱疹感染(带状疱疹)、艾滋病毒/艾滋病、晚期/癌症、截肢(包括乳房切除术)、腕管综合征、慢性酒精使用、暴露于辐射,以及神经毒性治疗药物的意外副作用,如某些抗HIV和化疗药物。外周神经痛是由于损伤、创伤、长时间的压力或炎症导致身体相应区域的麻木和疼痛而对周围神经造成的损害。
神经性疼痛通常被描述为“灼伤感”、“电刺激感”、“刺痛感”、或“阵痛感”。它的特征通常是慢性动态异位痛症(定义为运动刺激引起的疼痛,通常不会引起疼痛反应,如轻触碰)和痛觉过敏(定义为对正常疼痛刺激的敏感度增加),并可能持续数月或数年,直到任何受损组织明显愈合之后
患有癌症的患者也会有痛感,这是由多种原因引起的:炎症、压迫、侵袭、转移到骨骼或者其他组织。
在某些情况下,在没有有害刺激、组织损伤或神经系统损伤的情况下会出现疼痛,称为功能性疼痛,包括但不限于纤维肌痛、紧张型头痛和肠易激障碍.
偏头痛是一种与支配脑膜的感觉纤维激活有关的头痛。
瘙痒(瘙痒)是一种可能是局部发生也可能全身发生的皮肤病,可与皮肤损伤(皮疹、特应性湿疹、风疹)相关。瘙痒伴随着许多情况,包括但不限于压力、焦虑、太阳的紫外线辐射、代谢和内分泌疾病(如肝脏或肾脏疾病、甲状腺功能亢进症)、癌症(如淋巴瘤)、对药物或食物的反应、寄生虫和真菌感染、过敏反应、血液疾病(如真性红细胞增多症)和皮肤病。瘙痒是由小直径初级感觉神经元的一个子集-瘙痒感受器介导的,它们具有许多伤害性感受器神经元的特征,包括但不限于TRPV1通道的表达,以及其他大孔通道(如TRPV2-4,TRPA1,TRPM8,ASIC和P2X(2/3))的表达。某些瘙痒介质--如二十烷类化合物、组胺、缓激肽、ATP和各种神经营养素--具有内源性花青素的功能。外用辣椒素可抑制组胺引起的瘙痒。因此,类似伤害性感受神经元的瘙痒感受神经元是这种递送离子通道阻滞剂方法的合适靶点。
咳嗽是一种防御性反射,旨在保护气道免受异物侵袭,并帮助清除管腔碎片。然而,这种反射在一些疾病中会变得异常,从而导致存在过度咳嗽或异咳状态的无效性干咳。过度咳嗽和异位咳嗽状态通常是慢性的,持续时间超过3个月,可表现在许多气道疾病状态,包括哮喘、COPD、哮喘-COPD重叠综合征(ACOS)、间质性肺纤维化(IPF)和肺癌,这些疾病包括哮喘、COPD、哮喘-COPD重叠综合征(ACOS)、间质性肺纤维化(IPF)和肺癌。此外,不适当的咳嗽反射可在病毒感染后急性和慢性表现出来。此外,慢性咳嗽可能是特发性的,病因不明。
神经源性炎症是由感觉神经元的传出(运动)功能介导的一种炎症模式,由痛觉神经元(伤害性感受神经元)在外周释放的促炎介质分子既激活免疫细胞中的多种炎症途径,又作用于血管系统改变血流和毛细血管通透性。
神经源性炎症是由组织损伤、自身免疫性疾病、感染、过敏、暴露于各种组织中的刺激物引起的外周炎症,被认为在许多疾病(如偏头痛、关节炎、鼻炎、胃炎、结肠炎、膀胱炎和晒伤)的发病机制中起重要作用。减轻神经源性炎症的一种方法是阻断伤害性感受神经元的兴奋性,从而防止伤害性感受神经元外周终末的激活和促炎化学物质的释放。
尽管治疗疼痛、瘙痒和神经源性炎症的方法多种多样,但仍需要额外的药物。

具体实施方式
本发明提供如上所述的式(I)表示的化合物,或药学上可接受的盐、立体异构体、溶剂、水合物或其组合。本发明还提供了包含具有式(I)的化合物或其药学上可接受的盐的组合物,例如,包含有效量的式(I)化合物或其药学上可接受的盐和药学上可接受的赋形剂的组合物。本发明的组合物还可以包括本发明的化合物和生物活性剂。这里描述的组合物可以配制用于口服、静脉、肌肉内、直肠、皮肤、皮下、外用、经皮、舌下、鼻腔、吸入、阴道、鞘内、硬膜外或眼内给药。
本发明还提供了用于治疗患者的疼痛、咳嗽、瘙痒或神经源性炎症障碍的方法,包括给患者施用包含具有式(I)的化合物的组合物,其中当暴露或施加到通道的内表面时,该化合物抑制存在于伤害感受神经元和/或咳嗽感受神经元和/或瘙痒感受神经元中的一个或多个电压门控离子通道,但是当施加到通道的外表面时,该化合物基本上不抑制该通道,并且,其中,当通道被活化该化合物能够通过大孔通道进入伤害感受神经元、咳嗽感受神经元或者瘙痒感受神经元时,所述化合物能够抑制所述伤害感受神经元、咳嗽感受神经元和/或瘙痒感受神经元上的一个或者一个以上电压门控离子通道。
在某些实施方案中,大孔通道是瞬态受体电位离子通道(Trp通道)。在其他实施方案中,Trp通道由外源性或内源性激动剂激活。在依旧其他实施方案中,大孔道是TRPA1、TRPV1-4、TRPM8、ASIC或P2X。在特定实施方案中,当受体/通道被激活时,该化合物能够通过TRPA1、TRPV1-4、TRPM8、ASIC或P2X受体/通道进入伤害感受神经元、咳嗽感受神经元或瘙痒感受神经元。在依旧另一个实施方案中,该化合物抑制电压门控钠通道。在依旧另一个实施方案中,由本发明的方法、组合物和试剂盒治疗的疼痛类型选自神经性疼痛、炎症性疼痛、伤害性疼痛、感染引起的疼痛和程序性疼痛,或者其中神经源性炎症障碍选自过敏性炎症、哮喘、慢性咳嗽、结膜炎、鼻炎、牛皮癣、炎症性肠病、间质性膀胱炎和特应性皮炎。
这里识别出式(I)所示化合物:
所述化合物能够通过在痛觉感受神经元和/或咳嗽感受神经元和/或瘙痒感受神经元上表达但不在运动神经元上表达的开放的大毛孔通道。因为本发明的离子通道阻断化合物带正电荷,它们不是膜透过性的,所以不能进入不表达大孔通道的细胞。由于内源性配体的释放或热刺激的激活,大孔通道在与疼痛(例如炎症)相关的组织条件中通常更活跃,因此本发明的离子通道阻滞剂可以单独用于选择性地靶向激活的伤害性感受神经元,以便有效地治疗(例如,消除或减轻)疼痛、咳嗽、瘙痒或神经源性炎症。本发明的离子通道阻滞剂还可以与一种或多种外源性大孔受体激动剂结合使用,以选择性地靶向伤害性感受神经元,以便有效地治疗(例如,消除或减轻)疼痛、咳嗽、瘙痒或神经源性炎症。
痛觉神经元中的电压依赖性离子通道是目前开发治疗疼痛药物的兴趣点。阻断痛觉神经元中的电压依赖性钠通道可以通过阻断动作电位的启动和传递来阻断疼痛信号。此外,阻断伤害感受神经元中的电压依赖性钠通道可以通过阻止伤害感受器外周终末的激活及其促炎症化学物质的释放来减少或消除神经源性炎症。
迄今为止,用分子阻断钠通道或钙通道的治疗的一个限制是,绝大多数这种外用分子是疏水的,可以通过细胞膜。因此,它们将进入所有细胞,从而对仅影响伤害感受神经元没有选择性。
本发明的抑制剂不能透过细胞膜,仅仅当存在于伤害感受神经元细胞内时有效,因此必须通过通道或受体穿过细胞膜,例如大孔通道(例如TRPAV1-4、TRPA1、TRPM8、ASIC和P2X(2/3)),以产生效应。在正常情况下,伤害感受神经元中的大多数大孔通道并不活跃,但需要有害的热、机械或化学刺激来激活它们。例如,伤害感受器中的TRP通道可被外源性TRP配体(即TRP激动剂)如辣椒素激活而打开TRPV1通道。因此,选择性靶向伤害感受神经元的一种方法是将膜不透过性离子通道抑制剂与允许抑制剂通过TRP通道进入细胞的外源性TRP配体共同施用。除了辣椒素,外源性TRP配体也可以是另一种辣椒碱、芥子油或利多卡因。在另一个实施例中,TRP通道可能对外源性刺激激活剂(如从烟雾中吸入的丙烯醛)或化学制剂(如催泪瓦斯)作出反应而激活。
在某些情况下,当不存在外源性大孔通道激动剂/配体的情况下,由于组织损伤、感染、自身免疫、特应性、缺血、缺氧、细胞应激、免疫细胞激活、免疫介质产生以及氧化应急产生的内源性炎症激活剂也可激活大孔通道。在这种条件下,内源性分子(例如质子、脂质、以及反应性氧)可以激活伤害感受神经元上表达的大孔通道,允许膜不渗透的电压门控离子通道阻滞剂通过内源性激活的大孔通道进入伤害感受神经元内部。大孔通道的内源性炎症激活剂包括前列腺素、一氧化氮(NO)、过氧化氢(H2O2)、半胱氨酸反应性炎症介质,如4-羟基壬烯醇、质子、ATP、内源性烯基醛类、内源性大麻素类、以及免疫介质(如白细胞介素1(IL-1)、神经生长因子(NGF)以及缓激肽,其受体与大孔通道耦合)。

指示
本发明的化合物、组合物、方法以及本发明的试剂盒可用于治疗与多种疾病中的任何一种相关的疼痛、咳嗽或瘙痒,包括三叉神经营养综合征、红细胞痛、背部和颈部疼痛、下背部疼痛、癌症疼痛、妇科和分娩疼痛、腹壁痛、慢性腹壁痛、纤维肌痛、过敏性鼻炎、关节炎、,类风湿性关节炎、骨关节炎、风湿性疼痛、骨科疼痛、急性和带状疱疹后神经痛和其他神经性疼痛(包括周围神经病变)、镰状细胞危象、肌肉痛、外阴痛、直肠痛、肛提肌综合征、直肠痛、肛周痛、痔疮痛、胃痛、溃疡、,炎症性肠病、肠易激综合征、肠易激综合征、口腔粘膜炎、食管炎、间质性膀胱炎、尿道炎和其他泌尿系统疼痛、牙痛、灼痛、头痛、眼部刺激、结膜炎(如过敏性结膜炎)、眼睛发红、干眼症、干眼症(慢性眼部疼痛),复杂区域疼痛综合征、急性术后疼痛、术后疼痛、术后眼部疼痛、以及程序性疼痛(即与注射、脓肿引流、手术、牙科手术、眼科手术、眼部刺激、结膜炎(如过敏性结膜炎)相关的疼痛)、眼睛发红、干眼症、关节镜检查和其他医疗器械的使用、美容外科手术、皮肤科手术、固定骨折、活组织检查、等等).
由于痛觉感受神经元的一个亚类介导瘙痒感觉,因此本发明化合物、组合物、方法以及本发明的试剂盒也可用于治疗瘙痒等疾病患者的瘙痒(包括,但是不局限于,肱桡动脉,慢性特发性,生殖器/肛门,感觉异常疼痛以及头皮瘙痒)、过敏性皮炎、特应性皮炎、接触性皮炎、毒葛、感染、寄生虫、昆虫叮咬、怀孕、代谢紊乱、肝或肾功能衰竭、药物反应、过敏反应、湿疹、手部湿疹、生殖器和肛门瘙痒、痔疮瘙痒、以及癌症。
由于伤害感受神经元的一个亚类可引发异常咳嗽反射,因此,本发明化合物、组合物、方法以及本发明的试剂盒还可用于治疗哮喘、COPD、哮喘-COPD重叠综合征(ACOS)、间质性肺纤维化(IPF)、特发性肺纤维化、病毒后咳嗽、感染后咳嗽、慢性特发性咳嗽和肺癌患者的咳嗽。
本发明化合物、组合物、方法以及本发明的试剂盒也可用于治疗神经源性炎症和神经源性炎症疾病。炎症是对有害刺激的一系列复杂反应,导致局部红肿以及疼痛,炎症可以是先天性的,也可以是适应性的,后者由抗原驱动,由免疫细胞介导(免疫介导的炎症)。神经源性炎症源于痛觉神经元(伤害感受神经元)的传出功能,其中神经肽和其他作为促炎症介质的化学物质在激活时从伤害感受器的外周终末释放。这种释放过程是由含肽囊泡的钙内流和胞吐介导的,并且促炎神经肽包括P物质、神经激肽A和B(统称为速激肽)、降钙素基因相关肽(CGRP)以及血管活性肠多肽(VIP)。
外周末梢化学物质的释放刺激多种炎症反应。首先,P物质的释放可导致毛细血管通透性增加,从而使血浆蛋白从血管内腔室泄漏到细胞外空间(血浆外渗),导致水肿。这可以被检测为一种风团(皮肤的一种坚硬、隆起的肿胀),它是三种炎症反应中的一种——风团、红斑、以及被称为刘易斯三重反应的耀斑。其次,降钙素基因相关肽的释放导致血管扩张,导致血流量增加。这可以被检测为耀斑,这是刘易斯三重反应的另一个组成部分。
P物质对免疫细胞(如巨噬细胞、T细胞、肥大细胞、以及树突状细胞)通过其神经激肽-1(NK1)受体产生前免疫作用。这一作用以及被记录在过敏性鼻炎、胃炎、以及结肠炎种,并且代表神经源性和免疫介导的炎症成分之间的分界线。一个伤害感受神经元释放的P物质也可能作用于相邻伤害感受神经元上的NK1受体,使其致敏或激活,导致激活和传入/传出功能的扩散。伤害感受神经元的这些传出功能可以通过以下方式触发:1)通过对伤害感受神经元终端施加足够的外周刺激(例如按压)直接激活伤害感受神经元终端;2)通过轴突反射间接逆向激活非受刺激的伤害感受神经元末端,其中当到达外周的会聚轴突分支点时,来自伤害感受神经元一个末端的动作电位输入,导致动作电位从分支点向下移动到非受激终端的外围终端;以及3)中枢神经系统中的伤害感受神经元中枢终末向外周移动时的活动导致的激活(例如,GABA产生的中枢终末初级传入去极化足以启动以“错误方式”移动的动作电位)。
对肺部的ILC2细胞的基因组分析表明,感觉神经元释放的几种神经肽的受体表达,包括SP、CGRP和VIP,为伤害感受神经元与这些细胞直接交流提供了机会。特别是,发现VIP在NaV1.8+结状神经节神经元中表达,包括OVA暴露小鼠的肺传入。用辣椒素或IL5刺激培养的结糖神经节神经元也会释放VIP,而与载体激发小鼠相比,暴露于OVA的小鼠BALF中的VIP含量升高(Talbot et al.,Neuron.2015 July 15;87(2):341–354)。这些数据表明VIP在发炎的肺中释放,并可通过使用本发明的带电钠通道阻滞剂使神经元沉默来阻断。此外,当在TH2倾斜条件下培养的CD4+T细胞暴露于重组小鼠VIP时,IL-13和IL-5的转录水平增加,表明VIP有助于TH2细胞转录这些II型调节性细胞因子。
免疫细胞释放的免疫介质也能激活伤害感受神经元。肥大细胞靠近初级伤害感受神经元,在许多情况下有助于伤害感受神经元致敏。促泌剂化合物48/80的注入能够促进硬脑膜内肥大细胞脱颗粒,导致脑膜伤害感受器兴奋。肥大细胞脱颗粒也有助于神经生长因子诱导的热痛觉过敏的快速发作。巨噬细胞通过释放几种可溶性介质促进伤害感受神经元致敏。坐骨神经部分结扎后,巨噬细胞和雪旺氏细胞中趋化因子-巨噬细胞炎性蛋白-1α(MIP-1α)及其受体CCR1和CCR5的表达增加,并有助于神经病理性疼痛的发生。淋巴细胞有助于外周伤害感受神经元的致敏。神经损伤后,T细胞浸润坐骨神经和背根神经节(DRG)。在缺乏T细胞的啮齿类动物中,由神经损伤引起的痛觉过敏和痛觉超敏明显减轻或消失,免疫抑制剂雷帕霉素减轻大鼠的神经病理性疼痛,部分原因是对T细胞的影响。在T细胞亚群中,1型和2型辅助性T细胞(TH1和TH2细胞)在神经病理性疼痛中具有不同的作用。TH1细胞通过释放促炎性细胞因子(IL-2和干扰素-γ(IFN-γ))促进神经病理性疼痛行为,而TH2细胞通过释放抗炎性细胞因子(IL-4、IL-10和IL-13)抑制神经病理性疼痛行为。补体系统在炎症性痛觉过敏和神经病理性疼痛中也起作用。C5a是一种过敏毒素,是补体级联反应的重要效应器,与中性粒细胞上的C5aR1受体结合后,它成为一种有效的中性粒细胞引诱剂(Ren&Dubner,Nat.Med.16:1267-1276(2010))。
细菌感染可以直接激活伤害感受神经元,并且金黄色葡萄球菌引起的小鼠疼痛不需要通过TLR2,MyD88,T细胞,B细胞以及中性粒细胞和单核细胞介导的免疫反应(Chiu等人,《自然》501:52-57(2013))。小鼠的机械性和热性痛觉过敏与活细菌负荷有关,而不是与组织肿胀或免疫激活有关。细菌通过不同的机制诱导伤害感受器神经元的钙流量和动作电位,部分通过细菌N-甲酰化肽和成孔毒素α-溶血素。包括伤害感受神经元在内的Nav1.8系神经元的特异性消融消除了细菌感染期间的疼痛,但同时增加了局部免疫浸润和引流淋巴结的淋巴结病。因此,细菌病原体通过直接激活调节炎症的感觉神经元而产生疼痛,这是神经系统在宿主-病原体相互作用中的一个意想不到的作用。Talbot等人(Neuron.2015 July15;87(2):341–354)的数据也表明,在致敏动物中暴露于过敏原期间,伤害感受神经元被激活。
在某些疾病中,神经源性炎症导致由组织损伤、自身免疫疾病、感染引起的外周炎症,并且暴露于软组织、皮肤、呼吸系统、关节、泌尿生殖道和胃肠道、肝脏、以及大脑。神经源性炎症疾病包括,但不限于,过敏性炎症、炎症性肠病、间质性膀胱炎、特应性皮炎、哮喘、结膜炎、关节炎、结肠炎、接触性皮炎、糖尿病、湿疹、膀胱炎、胃炎、偏头痛、银屑病、鼻炎、酒渣鼻、晒伤、胰腺炎、慢性咳嗽、慢性鼻窦炎、创伤性脑损伤、多菌败血症、腱病、慢性荨麻疹、风湿性疾病、急性肺损伤、暴露于刺激物、吸入刺激物、污染物或化学武器,如本文所述。
疼痛、咳嗽、瘙痒以及神经源性严重的评估
为了测量本发明化合物、组合物、方法以及本发明的试剂盒在治疗与肌肉骨骼、免疫炎症和神经病变相关的疼痛时的功效,可使用测量指数表。有用的指数包括视觉模拟量表(VAS)、利克特量表、分类疼痛量表、描述符、Lequesne指数、WOMAC指数、以及AUSCAN索引,每种索引在本领域中都是众所周知的。这些指数可用于测量疼痛、瘙痒、功能、僵硬或其他变量。
视觉模拟量表(VAS)提供一维定量的测量方法。VAS通常使用距离表示,例如以规则距离间隔(例如,十个1-cm间隔)绘制的具有散列标记的线的图片。例如,可以要求患者通过选择线上最符合疼痛或瘙痒感觉的点对疼痛或瘙痒感觉进行排序,其中线的一端对应“无疼痛”(0cm)或“无瘙痒”,线的另一端对应“无法忍受的疼痛”或“无法忍受的瘙痒”(10cm)。该方法提供了一种简单而快速的方法来获取有关患者如何经历疼痛或瘙痒的定量信息。VAS量表及其用途如美国专利6709406及6432937中所述。
利克特量表同样提供了一维定量的测量方法。通常,利克特量表具有从低值(例如,0,表示无疼痛)到高值(例如,7,表示极度疼痛)的离散整数值。疼痛患者被要求在低值和高值之间选择一个数字来表示疼痛程度。利克特量表及其用途如美国专利6623040及6766319中所述。
Lequesne指数和西安大略省和麦克马斯特大学(WOMAC)骨关节炎指数评估疼痛、功能、以及膝关节和髋关节僵硬程度,使用自填问卷调查OA患者。膝关节和髋关节都包含在WOMAC中,而膝关节和髋关节分别有一份Lequesne问卷。与VAS或利克特相比,这些问卷非常有用,因为它们包含更多的信息内容。WOMAC指数和Lequesne指数问卷已在骨性关节炎中得到广泛验证,包括在外科环境中(例如膝关节和髋关节置换术)。它们的度量特征没有显著差异。
AUSCAN(澳大利亚-加拿大手关节炎)指数表采用有效、可靠的以及反应性患者自我报告问卷。在一个情况下,该问卷包含三个维度内的15个问题(疼痛,5个问题;僵硬,1个问题;身体功能,9个问题)。AUSCAN指数可利用利克特或VAS量表等。
在本发明的方法、组合物以及试剂盒中使用的用于疼痛测量的量表包括疼痛描述量表(PDS)、视觉模拟量表(VAS)、言语描述量表(VDS)、数字疼痛强度量表(NPI)、神经病理性疼痛量表(NPS)、神经病理性疼痛症状量表(NPSI)、当前疼痛量表(PPI)、老年疼痛量表(GPM),麦吉尔疼痛问卷(MPQ)、平均疼痛强度(描述符差异量表)、数字疼痛量表(NPS)全球评估分数(GES)、简式麦吉尔疼痛问卷、明尼苏达多相人格问卷、疼痛概况和多维疼痛问卷、儿童健康问卷、以及儿童评估问卷。
瘙痒可通过主观测量(VAS、利克特、描述表)进行测量。另一种方法是使用振动传感器或运动敏感仪表测量痕迹,所述痕迹是瘙痒的客观关联。
咳嗽可以通过标准问卷(如莱斯特咳嗽问卷)以及经验证的客观仪器(如VitaloJAK)来测量。

膜片钳溶液和药物
细胞内溶液含有以下物质(单位:mM):CsCl 135、NaCl 10、EGTA 10、HEPES 10、MgCl2 2,并用CsOH调节至pH 7.2。外部溶液为正常的林格溶液,含有(单位:mM)NaCl 155、HEPES 10、葡萄糖10、KCl 3.5、CaCl2 1.5、MgCl2 1,并用NaOH调节至pH 7.4。CsCl来自马萨诸塞州哈弗希尔的阿尔法·埃萨尔。所有其他化学品均来自密苏里州圣路易斯市西格玛·奥尔德里奇。为了测试化合物内部嵌段程度,将待检测化合物溶解在指定测试浓度的内部溶液中。在对照实验中,内部溶液不含任何化合物。为了通过测试化合物测试外部堵塞程度,将化合物溶解在指示测试浓度的外部溶液中。
全细胞膜片钳协议
用四环素诱导细胞18-24小时后,将盖玻片置于室温下充满正常林格溶液的腔室中,并将腔室置于显微镜上。移液管在P97拉拔器(Sutter Instrument,加利福尼亚州诺瓦托市)上从硼硅酸盐玻璃中拔出,并用MF-830微型玻璃抛光(Narishige InternationalUSA,Inc,Amityville,NY),在室温下填充CsCl内部溶液时使其电阻为1.5-2.5mΩ。选择健康细胞(那些圆形半透明且无可见瑕疵的细胞)形成密封环境。移液管和细胞之间形成了密封以及一个短暂的抽吸脉冲用于“切入”并建立整个细胞结构。在电压方案开始之前,膜电位保持在-100mV。仅限串联电阻在1.5-5M之间的电池Ω留作分析。电压方案如下:将电池保持在-100mV下12ms,然后在-105mV下进行超极化步骤12ms,以监测泄漏。然后将细胞退至-100mV持续40ms。然后将细胞去极化至-20mV持续10ms,然后再返回至-100mV持续26ms。
测试化合物的内部阻断
一旦开始记录,电压方案以30秒的间隔运行5分钟,以获得稳定的基线。随后进行四次30秒的5Hz相同电压刺激,每次电压刺激后休息1分钟,然后在最后一次刺激之后进行0.33Hz刺激。使用PatchMaster软件和Heka EPC10(Heka Electronics公司,德国Lambrecht市)记录电流。仅接受向内电流振幅在-20mV、400pA和4nA之间的细胞。此外,泄漏电流大于其电流振幅10%的电池被丢弃。
数据分析:内部阻断
使用Patchmaster软件(HEKA Electronics公司,Lambrecht市,德国)绘制数据,并通过绘制电压阶跃至-20mV(峰值内向电流)期间的最小电流与时间的函数进行分析。为了确定实验过程中的耗竭程度,将5Hz刺激前的平均峰值内向电流振幅(2-3点)指定为基线(Ibaseline)。测量了最后5Hz刺激最后2秒钟内的平均峰值内向电流(Itest)。通过将Itest除以Ibaseline计算剩余控制分数电流。在每个记录日,用对照内部溶液测试三个细胞,并计算剩余电流的平均分数(Ctrl分数电流)。
为了确定内部应用的试验化合物产生的%阻断,进行了以下操作。5Hz刺激前的平均峰值内向电流振幅(2-3点)被指定为0%阻断(I0%block)。为了校正控制条件下的电流变化,将I0%阻断乘以剩余的平均Ctrl分数电流,得到校正的0%阻断电流。最后5Hz刺激最后2秒内的平均峰值内向电流被指定为未阻断电流(Iunblocked)。使用以下等式计算%阻断:(1-IUNBLOCK/(I0%block*剩余电流控制分数)x100)。
对本发明的代表性实施例进行了NaV 1.7的细胞内抑制试验。在32μM时,活性范围为抑制百分比:“+++++”(>95%)、“+++”95-70%、“++”(70-40%)或“+”(<40%)。结果如下所示。

表K
测试化合物的外部阻断
一旦开始记录,电压方案以30秒的间隔运行5分钟,以获得稳定的基线。随后使用相同电压方案进行5Hz刺激,直到实验结束。在5Hz刺激期间加入测试化合物,等待直到确保在加入化合物前细胞显示稳定的消耗率。加入测试化合物五分钟,随后用常规林格氏溶液洗脱。使用PatchMaster软件和Heka EPC10(Heka Electronics公司,德国Lambrecht市)记录电流。仅接受向内电流振幅在-20mV、400pA和4nA之间的细胞。此外,泄漏电流大于其电流振幅10%的电池被丢弃。
数据分析:外部阻断
使用Patchmaster软件(HEKA Electronics,Lambrecht市,德国)绘制数据,并通过绘制电压阶跃至-20mV(峰值内向电流)期间的最小电流作为时间的函数进行分析。为了确定外部施用的测试化合物产生的阻断百分比,进行了以下操作。在5Hz刺激期间在建立起稳定的电流衰减率之后,通过将峰值电流振幅的变化除以时间来计算速率(Raterundown)。添加化合物之前的平均峰值内向电流振幅(2-3秒)用于确定0%块(I0%block)。为了校正耗损,将I0%block减去(Raterundown*5分钟)以获得校正的0%阻断电流。洗涤前,5分钟化合物添加时间最后2-3秒内内向电流的平均峰值为未阻断电流(Iunblocked)。然后使用以下等式计算%阻断:电流阻断分数=1-IUNBLOCK/(I0%block-Raterundown*5分钟)。
对本发明的代表性实施例进行了NaV 1.7的细胞外抑制试验。活性范围为抑制百分比:“++++”(>95%)、“+++”95-70%、“++”(70-40%)或“+”(<40%)。结果如下所示。
