发明领域
本发明描述了新颖的化合物、或其药学上可接受的盐、包含它们的药物组合物及其医学用途。本发明的化合物具有作为Janus激酶(Janus Kinase)(JAK)抑制剂的活性,并且可用于治疗或控制瘙痒症,所述瘙痒症与过敏性皮炎、或动物中的特应性皮炎和其中免疫抑制/免疫调节将是期望的其他紊乱和适应症(indication)相关。本文还描述了通过施用作为JAK抑制剂的本发明的化合物来治疗瘙痒症和特应性皮炎的方法。
背景
瘙痒症(Pruritus)被定义为触发痒(itch)的不愉快的感觉,即抓痒(scratch)的欲望。像疼痛那样,痒是身体的基本防御机制中的一种。痒的基本生物学功能是警示动物存在潜在有害的毒素或其他危险因素,诸如携带疾病的昆虫,并且刺激旨在消除这些危险因素的反射。痒可以急性地表现,就像去除跳蚤和其他寄生虫的反射那样。可选择地,像疼痛那样,慢性痒可以成为自我延续的(self-perpetuating)和自身病理性的。当外周神经和中枢神经被过度刺激时产生慢性痒,所述过度刺激导致瘙痒症介导的神经纤维的激活和增殖。致敏的神经纤维(sensitized nerve fiber)已经表现出更容易刺激瘙痒症。慢性痒不仅需要对症治疗,还需要彻底的诊断处理来确定潜在的原因,以及多元模式疗法(multimodal therapy)来管理隐藏的影响。
蛋白激酶是催化蛋白质中特定残基的磷酸化的酶的家族,宽泛地被分类为酪氨酸激酶和丝氨酸/苏氨酸激酶。不适当的激酶活性已经涉及到许多疾病中,所述不适当的激酶活性由突变、过度表达或不适合的调节、调节异常(dys-regulation)或去调节(de-regulation)以及生长因子或细胞因子的产生过度或产生不足引起,所述疾病包括但不限于癌症、心血管疾病、过敏症、哮喘和其他呼吸系统疾病、自身免疫性疾病、炎性疾病、骨病、代谢紊乱以及神经紊乱和神经退行性紊乱诸如阿尔茨海默病。不适当的激酶活性触发与细胞生长、细胞分化、存活、凋亡、有丝分裂、细胞周期控制和细胞运动性有关的多种生物细胞响应,这些响应与前述疾病和相关疾病有关。因此,蛋白激酶已经由于用于治疗性干预的靶标而作为重要的一类酶兴起。特别地,细胞蛋白酪氨酸激酶的JAK家族(JAK-1、JAK-2、JAK-3和Tyk-2)在细胞因子信号传导中起核心作用(Kisseleva等人,Gene,2002,285,1;Yamaoka等人,Genome Biology 2004,5,253)。在细胞因子与它们的受体结合时,细胞因子激活JAK,然后使细胞因子受体磷酸化,从而为信号传导分子,特别是信号转导和转录激活因子(signal transducer and activator of transcription)(STAT)家族的成员创建停泊位点(docking site),这最终导致基因表达,从而刺激生物响应,诸如痒信号。JAK-STAT途径的激活还导致若干其他辅助生物活性(ancillary biologic activity),这些辅助生物活性促成炎症和瘙痒症过程,这些过程促成动物中的急性过敏反应,但还可能加重临床体征并且促成慢性过敏。
对于控制包括哺乳动物、鸟类和鱼的动物中的特应性皮炎的安全且有效的剂存在相当大的需求。哺乳动物的实例包括但不限于人类、牛(cattle)、绵羊、山羊、美洲驼(llamas)、羊驼(alpacas)、猪、马、驴、狗、猫和其他家畜哺乳动物或家养哺乳动物(domestic mammal)。鸟类的实例包括火鸡、鸡、鸵鸟和其他家畜鸟类或家禽。目前治疗动物中的特应性皮炎的市场由皮质类固醇主导,皮质类固醇在动物中,特别是在伴侣动物诸如狗中引起令人烦恼的且不合意的副作用。抗组胺药也被使用,但有效性差。环孢菌素的制剂(ATOPICATM)目前正被销售用于狗和猫中的特应性皮炎,但价格昂贵并且具有缓慢的效力开始(onset of efficacy)。此外,ATOPICATM存在GI耐受性问题。WO 2010/020905公开了用于治疗瘙痒症的JAK抑制剂。
概述
本发明的化合物是对包括JAK 1的JAK具有效力的新颖的JAK抑制剂。这些化合物将是类固醇使用或已经在市场上的JAK抑制剂的替代物,并且提供了慢性瘙痒症和炎症的解决方案,这些慢性瘙痒症和炎症将以特应性皮炎持续存在,或者在去除过敏原或病原体(causative agent)之后缓慢消退,所述过敏原或病原体诸如在跳蚤过敏性皮炎中的跳蚤。

在某些实施方案中,本文公开的化合物可以具有一个或更多个不对称中心;并且因此,这样的化合物可以作为单独的(R)-或(S)-对映异构体或作为其混合物产生。除非另有指示,例如通过指定在式的任何位置处的立体化学,否则在本说明书和权利要求书中的特定化合物的描述或命名意图包括单独的对映异构体及其混合物(外消旋的或以其他方式的)两者。用于确定立体化学和分离立体异构体的方法是本领域熟知的。
在某些实施方案中,本文公开的化合物是“立体化学纯的”。立体化学纯的化合物具有将被本领域技术人员认为是“纯的”立体化学纯度水平。当然,此纯度水平可以小于100%。在某些实施方案中,“立体化学纯的”指定大体上不含、即至少约85%或更多不含替代异构体的化合物。在特定实施方案中,化合物是至少约85%、约90%、约91%、约92%、约93%、约94%、约95%、约96%、约97%、约98%、约99%、约99.5%或约99.9%不含其他异构体。

此外,由式(I)代表的化合物的药学上可接受的前药也包括在本发明中。药学上可接受的前药指的是具有这样的基团的化合物,该基团可以通过溶剂分解或在生理条件下被转化为氨基基团、羟基基团、羧基基团或类似基团。形成前药的基团的实例包括如在Prog.Med.,5,2157-2161(1985)或“Pharmaceutical Research and Development”(Hirokawa Publishing Company,1990),第7卷,Drug Design,163-198中描述的那些。术语前药在整个说明书中被用于描述在施用至患者时提供活性化合物的化合物的任何药学上可接受的形式。药学上可接受的前药指的是在宿主中被代谢,例如被水解或被氧化以形成本发明的化合物的化合物。前药的典型实例包括在活性化合物的官能部分上具有生物不稳定的保护基团(biologically labile protecting group)的化合物。前药包括可以被氧化、还原、胺化(aminate)、去氨基化(deaminate)、羟基化、去羟基化、水解、脱水(dehydrolyze)、烷基化、去烷基化、酰化、去酰化、磷酸化、去磷酸化以产生活性化合物的化合物。

Z'-LYTE测定条件:测试化合物在孔中在1%DMSO(最终)中进行筛选。使用三种筛选浓度(10nM、100nM和1000nM)的测试化合物。
肽/激酶混合物:将所有肽/激酶混合物在合适的激酶缓冲液中稀释至2X工作浓度(对于JAK1,2X JAK1/Tyr 06混合物在50mM HEPES pH 6.5、0.01%BRIJ-35、10mM MgCl2、1mM EGTA、0.02%NaN3中制备。最终10μL激酶反应由以下组成:在50mM HEPES pH 7.0、0.01%BRIJ-35、10mM MgCl2、1mM EGTA、0.01%NaN3中的21.2ng-91.5ng JAK1和2μM Tyr06。在1小时的激酶反应温育之后,加入5μL的1:128稀释的显影试剂A(DevelopmentReagent A))。
ATP溶液:将所有的ATP溶液在激酶缓冲液中稀释至4X工作浓度(50mM HEPES pH7.5、0.01%BRIJ-35、10mM MgCl2、1mM EGTA)。
ATP:Km表观值先前使用Z'-LYTE测定法确定。
10X新颖的PKC脂质混合物:2mg/ml磷脂酰丝氨酸,0.2mg/ml DAG在20mM HEPES中,pH 7.4,0.3%CHAPS。
对于5mL 10X新颖的PKC脂质混合物:
1.向玻璃管中加入10mg磷脂酰丝氨酸(Avanti极性脂质部分(Avanti PolarLipids Part)#8400032C或840039C)和1mg DAG(Avanti极性脂质部分#800811C)。
2.通过在氮气流下蒸发至透明的薄膜,从脂质混合物中去除氯仿。管以一定角度的连续旋转以确保脂质溶液的最大表面积,将促成最薄的膜。
3.向干燥的脂质混合物中加入5mL重悬缓冲液,20mM HEPES、0.3%CHAPS、pH 7.4。
4.温和地加热至50℃-60℃持续1-2分钟,并且在短时间间隔内进行涡旋,直到脂质溶解为透明或轻微浑浊的溶液。典型地,脂质在2-3次加热/涡旋循环之后处于溶液中。
5.冷却至室温,等分试样分成单次使用体积,并在-20℃储存。
