Definitions

  • the present invention relates to a compound of the formula (I) or a pharmaceutically acceptable salt thereof, and to its use in the preparation of a medicament for treating a disease associated with an A 2A receptor.
  • the adenosine A 2A receptor is widely distributed in human tissues. This receptor is highly expressed in tissues such as spleen, thymus, white blood cells, platelets, GABA-type neurons and olfactory bulbs. It is also expressed in the heart, lungs, blood vessels, and other parts of the brain. Adenosine A 2A receptors are commonly co-existing with other GPCRs and become heterodimers. For example, A 2A receptors can form heterodimers with dopamine D 2 , cannabinoid CB 1 , glutamic acid mGluR5 , etc. .
  • Adenosine A 2A receptors play an important role in regulating vasodilation, supporting the formation of new blood vessels, protecting body tissues from damage caused by inflammation, and adenosine A 2A receptors also affect the indirect pathways of the basal ganglia. The degree of activity.
  • the decomposition of cellular tissues and the environment of hypoxia cause a large amount of decomposition of ATP, which leads to extracellular adenosine enrichment, and the concentration is abnormally high, which is 10-20 times of the normal value.
  • Binding of high concentrations of adenosine to the A2A receptor activates the adenosine signaling pathway.
  • This signaling pathway is a mechanism that protects the body's tissues through immunosuppression in the event of damage to the body's tissues.
  • adenosine signaling pathway leads to long-term inhibition of the innate immune response, which produces immune tolerance, which in turn leads to the loss of controlled growth of adenosine and A2A receptors in white blood cells (such as lymphocytes).
  • white blood cells such as lymphocytes.
  • the combination of T lymphocytes, natural killer cells, dendritic cells, etc. inhibits the effector functions that these white blood cells should have in the immune system.
  • Binding of adenosine to the A2A receptor increases the expression of CD39, CD73 and CTLA4 (T cell checkpoints), resulting in more Treg cells with greater immunosuppression.
  • Blocking the A 2A receptor adenosine signaling pathway can reduce the inhibition of the immune system and enhance the immune function of T cells, and is therefore considered to be a promising negative feedback mechanism to inhibit tumor growth.

技术领域
本发明涉及式(I)所示化合物或其药学上可接受的盐,并涉及其在制备治疗与A 2A受体相关疾病的药物中的应用。
背景技术
腺苷A 2A受体在人体组织中有广泛的分布,这个受体在脾脏,胸腺,白血球,血小板,GABA型神经元和嗅球等组织器官中有高表达。同时在心脏,肺部,血管,和脑等其他部位中也有表达。腺苷A 2A受体一般和其他GPCR共同存在并结合在一起成为异质二聚体,比如A 2A受体可以和多巴胺D 2,大麻素CB 1,谷氨酸mGluR5等形成异质二聚体。腺苷A 2A受体在调节血管舒张,支持新血管的形成,保护身体组织免受由炎症引起的伤害等生命活动中有着重要的作用;腺苷A 2A受体也影响基底神经节间接通路的活性程度。
在实体瘤中,细胞组织的分解和缺氧的环境造成了ATP大量分解,因此导致细胞外腺苷富集,浓度异常地高,为正常值的10-20倍。高浓度的腺苷和A 2A受体的结合会激活腺苷信号通路。这个信号通路是一种在机体组织损伤时通过免疫抑制来保护了机体组织的机制。腺苷信号通路的激活导致了对先天性免疫应答的长期抑制,这种长期抑制会产生免疫耐受性,进而导致恶性肿瘤失去控制的生长腺苷和A 2A受体在白血球里(譬如淋巴细胞,T淋巴细胞,自然杀手细胞,树突状细胞等)的结合抑制了这些白血球在免疫系统中应有的效应子功能。腺苷与A 2A受体的结合使CD39,CD73和CTLA4(T细胞检查点)的表达增加,从而产生更多的具有更强免疫抑制性的T reg细胞。阻断A 2A受体的腺苷信号通路可以减少对免疫系统的抑制作用,增强T细胞的免疫功能,因而被认为是很有希望的能抑制肿瘤生长的负面反馈机制。
单抗CS1003是一种针对PD-1的全长、全人源化免疫球蛋白G4(IgG4)单克隆抗体。

定义和说明
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物的中性形式接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机氨或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物的中性形式接触的方式获得酸加成盐。药学 上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
除了盐的形式,本发明所提供的化合物还存在前药形式。本文所描述的化合物的前药容易地在生理条件下发生化学变化从而转化成本发明的化合物。此外,前体药物可以在体内环境中通过化学或生化方法被转换到本发明的化合物。
本发明的某些化合物可以以非溶剂化形式或者溶剂化形式存在,包括水合物形式。一般而言,溶剂化形式与非溶剂化的形式相当,都包含在本发明的范围之内。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。

本发明的化合物可以存在特定的。除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中), 则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体过量(ee值)为80%。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚( 3H),碘-125( 125I)或C-14( 14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。术语“药学上可接受的载体”是指能够递送本发明有效量活性物质、不干扰活性物质的生物活性并且对宿主或者患者无毒副作用的任何制剂或载体介质代表性的载体包括水、油、蔬菜和矿物质、膏基、洗剂基质、软膏基质等。这些基质包括悬浮剂、增粘剂、透皮促进剂等。它们的制剂为化妆品领域或局部药物领域的技术人员所周知。
术语“赋形剂”通常是指配制有效的药物组合物所需要载体、稀释剂和/或介质。
针对药物或药理学活性剂而言,术语“有效量”或“治疗有效量”是指无毒的但能达到预期效果的药物或药剂的足够用量。对于本发明中的口服剂型,组合物中一种活性物质的“有效量”是指与该组合物中另一种活性物质联用时为了达到预期效果所需要的用量。有效量的确定因人而异,取决于受体的年龄和一 般情况,也取决于具体的活性物质,个案中合适的有效量可以由本领域技术人员根据常规试验确定。
术语“活性成分”、“治疗剂”,“活性物质”或“活性剂”是指一种化学实体,它可以有效地治疗目标紊乱、疾病或病症。
“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR) 0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。当一个取代基可以连接到一个环上的一个以上原子时,这种取代基可以与这个环上的任意原子相键合,例如,结构单元

表示取代基R可在环己基或者环己二烯上的任意一个位置发生取代。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,

中连接基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成

也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
Figure PCTCN2018107899-appb-000048

实验材料:BALB/c小鼠(雌性);小鼠结肠癌CT26细胞(中国科学院典型培养物保藏委员会细胞库),体外单层培养,培养条件为采用含10%胎牛血清RPMI-1640培养基,37℃ 5%CO 2培养箱中培养。用胰酶-EDTA进行常规消化处理传代。当细胞处于指数生长期,饱和度为80%-90%时,收取细胞,计数。

化合物的抑瘤疗效用GI(%)或相对肿瘤增殖率T/C(%)评价。相对肿瘤增殖率T/C(%)=Vt/Vc×100%(Vt:治疗组平均瘤体积;Vc:阴性对照组平均瘤体积)。Vt与Vc取同一天数据。
GI(%),肿瘤抑制率。GI(%)=1-Vt/Vc×100%。
统计分析基于试验结束时相对肿瘤体积和肿瘤重量运用SPSS软件进行分析。两组间比较用t-test进行分析,三组或多组间比较用one-wayANOVA进行分析,如果方差齐(F值无显著性差异),应用Tukey’s法进行分析,如果方差不齐(F值有显著性差异),应用Games-Howell法进行检验。P<0.05认为有显著性差异。
在开始给药后第20天,溶媒组的肿瘤体积达到847.09±79.65mm 3,CS1003(1mg/kg)组的肿瘤体积为487.34±109.07mm 3,其抑瘤率为42.47%(与对照组无显著性差异)。联合用药的各组与溶媒组相比均可显著抑制体内移植瘤的生长,其中实施例6盐酸盐联合CS1003的药效与其剂量和给药频率呈正相关。25mg/kg,50mg/kg和100mg/kg的实施例6盐酸盐与1mg/kg的CS1003联合用药在实验终点的瘤体积分别为312.06±80.17mm 3,246.48±62.57mm 3,和233.10±59.55mm 3;抑瘤率分别为63.16%,70.90%,和72.48%(P<0.001)。而实施例6盐酸盐(50mg/kg)每天两次给药联合CS1003表现出更强的抑瘤效果,该组在实验终点时的平均瘤体积为142.17±40.30mm 3,抑瘤率83.22%(P<0.001)。由此可见,实施例6盐酸盐在与CS1003联合预防给药时可以显著抑制小鼠结肠癌细胞CT26的体内同种移植瘤的生长。
实施例6盐酸盐(50mg/kg)+CS1003(1mg/kg),实施例6盐酸盐(100mg/kg)+CS1003,及实施例6盐酸盐(50mg/kg,每天两次)+CS1003,与实施例6盐酸盐单药相比均有显著差异,其中与50mg/kg实施例6盐酸盐相比,三组的P值分别为0.032,0.023和0.002;与100mg/kg实施例6盐酸盐相比,三组 的P值分别为0.038,0.027和0.002。同时利用金氏公式计算Q值,发现实施例6盐酸盐(50mg/kg)与CS1003有一定的叠加作用,而实施例6盐酸盐(100mg/kg)与CS1003有协同作用。
结论:本发明化合物与CS1003联合用药获得了较好的抑瘤效果,本发明化合物与CS1003联用具有协同作用。
