Definitions
- the invention belongs to the field of medicinal chemistry, and particularly relates to a spirocyclic JAK inhibitor, a pharmaceutical composition containing the same, and applications.
- PKs Protein kinases
- PKs are a group of enzymes that constitute one of the largest human enzyme families that regulate a variety of important biological processes including, inter alia, cellular kinases that catalyze protein, lipid, sugar, nucleoside and other cellular metabolism phosphorylation and plays a key role in all aspects of eukaryotic cell physiology.
- Aberrant kinase activity has been shown to be involved in a number of human diseases, including cancer, autoimmune and inflammatory diseases.
- Janus kinases are cytoplasmic tyrosine kinases that transduce cytokine signals from membrane receptors to STAT transcription factors, which play an important role in the process of cytokine signaling.
- the JAK family includes four members, JAK1, JAK2, JAK3, and tyrosine kinase 2 (TYK2). JAKs typically associate in pairs with cytokine receptors as homodimers or heterodimers. Cytokines bind to their receptors, causing dimerization of the receptor molecules, and receptor-coupled JAKs approach each other and are activated by phosphorylation of interacting tyrosine residues.
- the JAK family transmits cytokine-mediated signals into cells through the JAK-STAT (signal transducer and activator of transcription) pathway.
- STAT Signal Transducer and Activator of Transcription
- JAK kinases show that blocking signal transduction at the level of JAK kinases holds promise for the development of treatments for inflammatory diseases, autoimmune diseases, myeloproliferative diseases and cancer. Inhibition of JAK kinases also aids in the treatment of skin immune diseases such as psoriasis and skin sensitization.
- skin immune diseases such as psoriasis and skin sensitization.
- Pfizer's Toficitinib for the treatment of rheumatoid arthritis
- Incyte's ruxolitinib for the treatment of myelofibrosis and acute graft-versus-host disease.
- JAK enzyme inhibitors also have some obvious toxic side effects.
- some JAK inhibitors are prone to cause the following side effects: infection, including pneumonia, viral infection (such as herpes zoster infection), bacterial infection, actinomycetes Infections (mycobacterial infections), fungal infections, decreased immunity (eg, decreased NK cells), and anemia.
- infection including pneumonia, viral infection (such as herpes zoster infection), bacterial infection, actinomycetes Infections (mycobacterial infections), fungal infections, decreased immunity (eg, decreased NK cells), and anemia.
- viral infection such as herpes zoster infection
- bacterial infection such as herpes zoster infection
- actinomycetes Infections mycobacterial infections
- fungal infections eg, decreased NK cells
- anemia e.g, decreased NK cells
- JAKs family kinases are responsible for regulating numerous signaling pathways. Since JAK1 and JAK3 are components of a common ⁇ -chain cytokine receptor complex, it is difficult to develop inhibitors that are highly selective for JAK1.
- JAK1 plays a key role in the regulation of biological responses, and JAK1 is widely expressed and associated with several major cytokine receptor families. It is involved through the IL-2 receptor gamma subunit family (IL-2, IL-4, IL-7R, IL-9R, IL-15R and IL-21R), the IL-4 receptor family (IL-4R, IL-21R) -13R), signaling of members of the gp130 receptor family and class II cytokine receptors, including the IL-10 receptor family and both the Type I and Type II IFN receptor families.
- IL-2 receptor gamma subunit family IL-2, IL-4, IL-7R, IL-9R, IL-15R and IL-21R
- IL-4 receptor family IL-4R, IL-21R

Description
本发明属于药物化学领域,具体涉及一种螺环JAK抑制剂、含其的药物组合物及应用。
蛋白激酶(PK)是调控多种重要生物过程的一组酶,其构成了人最大的酶家族之一,所述生物过程尤其包括细胞激酶催化蛋白质、脂质、糖、核苷和其他细胞代谢物的磷酸化并在真核细胞生理学的所有方面起关键作用。已经表明在许多人类疾病中涉及激酶活性异常,这些疾病包括癌症、自身免疫性疾病和炎性疾病。
Janus激酶(JAK)是转导细胞因子信号从膜受体到STAT转录因子的细胞质酪氨酸激酶,其在细胞因子信号传递过程中起重要作用。JAK家族包括四个成员JAK1、JAK2、JAK3及酪氨酸激酶2(TYK2)。JAK通常与细胞因子受体成对缔合作为均二聚体或杂二聚体。细胞因子与其受体结合,引起受体分子的二聚化,与受体偶联的JAKs相互接近并通过交互的酪氨酸残基磷酸化作用而活化。JAK家族通过JAK-STAT(信号转导与转录活化因子)通路将细胞因子介导的信号传递至细胞中。
信号转导和转录激活子(Signal Transducer and Activator of Transcription,STAT)是一组能与靶基因调控区DNA结合的胞质蛋白。作为JAKs的下游底物,STATs可以在外界信号的刺激下,发生酪氨酸磷酸化从而被激活,随后转入细胞核调节基因的转录。当细胞因子与其受体结合时,JAK家族成员自磷酸化和/或彼此转磷酸化,随后STATs磷酸化,然后迁移至细胞核内以调节转录。
许多异常的免疫应答,如过敏、哮喘、(异体)移植排斥、类风湿性关节炎、肌萎缩性脊髓侧索硬化症和多发性硬化症等自身免疫性疾病,骨髓增生失调,白血病和淋巴瘤等血液系统恶性肿瘤,它们的调节都与JAK/STAT信号通路有关。
研究表明,在JAK激酶水平下的阻断信号转导为炎性疾病、自身免疫病、骨髓增殖性疾病和癌症的治疗方法的开发提供了前景。JAK激酶的抑制也有助于皮肤免疫疾病如银屑病和皮肤敏化的治疗。已经上市的有辉瑞的托伐替尼(Toficitinib),用于治疗类风湿性关节炎;以及Incyte的鲁索替尼,用于治疗骨髓纤维化以及急性移植物抗宿主病。
然而,目前已有的一些JAK酶抑制剂也存在一些明显的毒副作用,例如一些JAK抑制剂容易引起以下副作用:感染,包括肺炎、病毒感染(如带状疱疹感染)、细菌感染、放线菌感染(分枝杆菌感染)、真菌感染、免疫力下降(如NK细胞减少)以及贫血。在美国,甚至因为部分严重的副作用而得到黑框警示(Black box),这些严重的副作用包括,例如急性肺结核、侵入性真菌感染、细菌感染、以及部分淋巴瘤或其它肿瘤。研究表明,目前已有的 JAK抑制剂往往对JAK1和JAK3均有抑制活性,大多数的这些副作用的产生与JAK3的活性受抑制有关。
然而,研究表明,JAKs家族激酶负责调节众多信号通路。由于JAK1和JAK3是常见的γ-链细胞因子受体复合物的组成部分,这导致开发对JAK1具有高选择性的抑制剂存在很大的难度。
JAK1在生物反应调节中起关键作用,且JAK1被广泛表达并与几种主要的细胞因子受体家族相关联。它参与通过IL-2受体γ亚单位家族(IL-2、IL-4、IL-7R、IL-9R、IL-15R和IL-21R)、IL-4受体家族(IL-4R、IL-13R)、gp130受体家族和II类细胞因子受体(包括IL-10受体家族以及I型和II型IFN受体家族两者)的成员的信号传导。
综上所述,目前本领域迫切需要研发出Janus激酶或相关激酶的抑制剂,尤其是对JAK1具有高选择性的抑制剂。

在本发明中,术语“取代”指特定的基团上的一个或多个氢原子被特定的取代基所取代。特定的取代基为在前文中相应描述的取代基,或各实施例中所出现的取代基。除非特别说明,某个取代的基团可以在该基团的任何可取代的位点上具有一个选自特定组的取代基,所述的取代基在各个位置上可以是相同或不同的。本领域技术人员应理解,本发明所预期的取代基的组合是那些稳定的或化学上可实现的组合。

本发明中的化合物可能形成的盐也是属于本发明的范围。除非另有说明,本发明中的化合物被理解为包括其盐类。在此使用的术语“盐”,指用无机或有机酸和碱形成酸式或碱式的盐。此外,当本发明中的化合物含一个碱性片段时,它包括但不限于吡啶或咪唑,含一个酸性片段时,包括但不限于羧酸,可能形成的两性离子(“内盐”)包含在术语“盐”的范围内。药学上可接受的(即无毒,生理可接受的)盐是首选,虽然其他盐类也有用,例如可以用在制备过程中的分离或纯化步骤。本发明的化合物可能形成盐,例如,化合物I与一定量如等当量的酸或碱反应,在介质中盐析出来,或在水溶液中冷冻干燥得来。
本发明中的化合物含有的碱性片段,包括但不限于胺或吡啶或咪唑环,可能会和有机或无机酸形成盐。可以成盐的典型的酸包括醋酸盐(如用醋酸或三卤代醋酸,如三氟乙酸)、己二酸盐、藻朊酸盐、抗坏血酸盐、天冬氨酸盐、苯甲酸盐、苯磺酸盐、硫酸氢盐、硼酸盐、丁酸盐、柠檬酸盐、樟脑盐、樟脑磺酸盐、环戊烷丙酸盐、二甘醇酸盐、十二烷基硫酸盐、乙烷磺酸盐、延胡索酸盐、葡庚糖酸盐、甘油磷酸盐、半硫酸盐、庚酸盐、己酸盐、盐酸盐、氢溴酸盐、氢碘酸盐、羟基乙磺酸盐(如,2-羟基乙磺酸盐)、乳酸盐、马来酸盐、甲磺酸盐、萘磺酸盐(如,2-萘磺酸盐)、烟酸盐、硝酸盐、草酸盐、果胶酸盐、过硫酸盐、苯丙酸盐(如3-苯丙酸盐)、磷酸盐、苦味酸盐、新戊酸盐、丙酸盐,水杨酸盐、琥珀酸盐、 硫酸盐(如与硫酸形成的)、磺酸盐、酒石酸盐、硫氰酸盐、甲苯磺酸盐如对甲苯磺酸盐、十二烷酸盐等等。

本发明中化合物的前药及溶剂合物也在涵盖的范围之内。此处术语“前药”是指一种化合物,在治疗相关疾病时,经过代谢或化学过程的化学转化而产生本发明中的化合物、盐、或溶剂合物。本发明的化合物包括溶剂合物,如水合物。
本发明中的化合物、盐或溶剂合物,可能存在的互变异构形式(例如酰胺和亚胺醚)。所有这些互变异构体都是本发明的一部分。
所有化合物的立体异构体(例如,那些由于对各种取代可能存在的不对称碳原子),包括其对映体形式和非对映形式,都属于本发明的设想范围。本发明中的化合物独立的立体异构体可能不与其他异构体同时存在(例如,作为一个纯的或者实质上是纯的光学异构体具有特殊的活性),或者也可能是混合物,如消旋体,或与所有其他立体异构体或其中的一部分形成的混合物。本发明的手性中心有S或R两种构型,由理论与应用化学国际联合会(IUPAC)1974年建议定义。外消旋形式可通过物理方法解决,例如分步结晶,或通过衍生为非对映异构体分离结晶,或通过手性柱色谱法分离。单个的光学异构体可通过合适的方法由外消旋体得到,包括但不限于传统的方法,例如与光学活性酸成盐后再结晶。
本发明中的化合物,依次通过制备、分离纯化获得的该化合物其重量含量等于或大于90%,例如,等于或大于95%,等于或大于99%(“非常纯”的化合物),在正文描述列出。此处这种“非常纯”本发明的化合物也作为本发明的一部分。
本发明的化合物所有的构型异构体都在涵盖的范围之内,无论是混合物、纯的或非常纯的形式。在本发明化合物的定义包含顺式(Z)和返式(E)两种烯烃异构体,以及碳环和杂环的顺式和反式异构体。
在整个说明书中,基团和取代基可以被选择以提供稳定的片段和化合物。
特定官能团和化学术语定义都详细介绍如下。对本发明来说,化学元素与Periodic Table of the Elements,CAS version,Handbook of Chemistry and Physics,75
th Ed.中定义的一致。特定官能团的定义也在其中描述。此外,有机化学的基本原则以及特定官能团和反应性在“Organic Chemistry”,Thomas Sorrell,University Science Books,Sausalito:1999,也有说明,其全部内容纳入参考文献之列。
本发明的某些化合物可能存在于特定的几何或立体异构体形式。本发明涵盖所有的化合物,包括其顺式和反式异构体、R和S对映异构体、非对映体、(D)型异构体、(L)型异构体、外消旋混合物和其它混合物。另外不对称碳原子可表示取代基,如烷基。所有异构体以及它们的混合物,都包涵在本发明中。
按照本发明,同分异构体的混合物含有异构体的比率可以是多样的。例如,在只有两个异构体的混合物可以有以下组合:50:50,60:40,70:30,80:20,90:10,95:5,96:4,97:3,98:2,99:1,或100:0,异构体的所有比率都在本发明范围之内。本专业内一般技术人员容易理解的类似的比率,及为更复杂的异构体的混合物的比率也在本发明范围之内。
本发明还包括同位素标记的化合物,等同于原始化合物在此公开。不过实际上对一个或更多的原子被与其原子量或质量序数不同的原子取代通常会出现。可以列为本发明的化合物同位素的例子包括氢、碳、氮、氧、磷、硫、氟和氯同位素,分别如
2H、
3H、
13C、
11C、
14C、
15N、
18O、
17O、
31P、
32P、
35S、
18F和
36Cl。本发明中的化合物,或对映体,非对映体,异构体,或药学上可接受的盐或溶剂化物,其中含有上述化合物的同位素或其他同位素原子都在本发明的范围之内。本发明中某些同位素标记化合物,例如
3H和
14C的放射性同位素也在其中,在药物和底物的组织分布实验中是有用的。氚,即
3H和碳-14,即
14C,它们的制备和检测比较容易。是同位素中的首选。此外,较重同位素取代如氘,即
2H,由于其很好的代谢稳定性在某些疗法中有优势,例如在体内增加半衰期或减少用量,因此,在某些情况下可以优先考虑。同位素标记的化合物可以用一般的方法,通过用易得的同位素标记试剂替换为非同位素的试剂,用批露在示例中的方案可以制备。
如果要设计一个本发明的化合物特定的对映体的合成,它可以不对称合成制备,或用手性辅剂衍生化,将所产生的非对映混合物分离,再除去手性辅剂而得到纯的对映体。另外,如果分子中含有一个碱性官能团,如氨基酸,或酸性官能团,如羧基,可以用合适的光学活性的酸或碱的与之形成非对映异构体盐,再通过分离结晶或色谱等常规手段分离,然后就得到了纯的对映体。
如本文所述,本发明中的化合物可与任何数量取代基或官能团取而扩大其包涵范围。通常,术语“取代”不论在术语“可选”前面或后面出现,在本发明配方中包括取代基的通式,是指用指定结构取代基,代替氢自由基。当特定结构中的多个在位置被多个特定的取代基取代时,取代基每一个位置可以是相同或不同。本文中所使用的术语“取代”包括所有允许有机化合物取代。从广义上讲,允许的取代基包括非环状的、环状的、支链的非支链的、碳环的和杂环的,芳环的和非芳环的有机化合物。在本发明中,如杂原子氮可以有氢取代基或任何允许的上文所述的有机化合物来补充其价态。此外,本发明是无意以任何方式限制允许取代有机化合物。本发明认为取代基和可变基团的组合在以稳定化合物形式在疾病的治疗上是很好的。此处术语“稳定”是指具有稳定的化合物,在足够长的时间内检测足以维持化合物结构的完整性,最好是在足够长的时间内都在效,本文在此用于上述目的。
本申请所涉及的化合物及其药学可接受的盐的代谢产物,以及可以在体内转变为本申请所涉及的化合物及其药学可接受的盐的结构的前药,也包含在本申请的权利要求中。
