Description
技术领域
本发明涉及可用作A2A受体拮抗剂的三唑并三嗪衍生物。本发明还涉及这些化合物及其药物组合物的制备方法。所述化合物及其药物组合物可用于治疗或预防与A2A受体的异常高活性有关的疾病,例如由A2A受体介导的免疫耐受型癌症和相关的细胞异常增殖。
背景技术
腺苷是一种天然存在的嘌呤核苷,能够调节各种生理功能。腺苷能与G蛋白偶联受体(GPCR)家族成员的嘌呤受体结合,其中包括腺苷A1、A2A、A2B和A3受体(A1R、A2AR、A2BR和A3R)。其中腺苷A2A受体(A2AR)能够以一种刺激的方式与腺苷酸环化酶偶联,从而诱导经典第二信使的信号途径,包括生成环磷酸腺苷(cAMP)(Current Medicinal Chemistry.2014,21,3918-3935)。A2AR能够在中枢神经系统和周围组织中介导腺苷发挥多种生理作用。A2AR与多巴胺D2受体在基底神经节的功能性相互作用促使人们数十年来进行A2AR拮抗剂作为治疗帕金森疾病药物的研究。A2AR拮抗剂的其它医疗应用还包括认知增强、神经保护以及止痛。最近的研究表明,对A2AR的抑制还可以是癌症治疗的有效方法(Computational andStructural Biotechnology Journal.2015,15,265–272)。
研究表明,A2AR可以保护肿瘤不受到抗肿瘤T细胞和其它免疫细胞的攻击(PNAS.2006,103,No.35,13132-7)。免疫系统有一系列的调节机制来避免组织受到自身免疫或对病原体的免疫反应的损害,包括内在性机制(例如胸腺中的负选择)和外围性机制(例如免疫删除、无免疫反应和调节性T细胞的有效运用等),这些机制都有助于建立自身免疫耐受。这些保护性机制包括受到活化的免疫反应中的淋巴细胞上调的各种抑制性受体。这些抑制性受体及其相关的信号网络被称为“免疫检查点通路”,这种负反馈机制对保护组织免受免疫伤害起着至关重要的作用。不过,尽管免疫检查点通路所产生的负反馈回路在调节过度免疫反应方面非常重要,但癌症却会使这个负反馈回路的运行失去应有的调节,并为肿瘤的免疫逃避提供了有效的途径。在众多的负反馈信号通路中,腺苷信号通路就是其中之一。通过抑制免疫反应,它能够有效地保护自身组织免受免疫损伤。
胞外腺苷可以通过结合腺苷受体(包括A1R、A2AR、A2BR和A3R)进行信号传导(DrugDev.Res.1996,39,243–52)。由于A2AR和A2BR在多种免疫细胞和内皮细胞上都有表达,胞外腺苷通过A2AR(高亲和力)和A2BR(低亲和力)所传递的腺苷信号在免疫应答过程中对组织的自身保护十分有效(Autoimmunity.2007,40,425–32;Handb.Exp.Pharmacol.2009,193,399–441;Cancer Discov.2014,4,879–88)。特别是,由于腺苷对A2AR具有更高的亲和力,以及A2AR在众多的免疫细胞中都高表达,对免疫反应的这种自身保护大多通过A2A腺苷受体完成(Nature.2001,414,916–20)。
在正常生理条件下,细胞可以通过快速的细胞摄取来平衡胞外腺苷的含量,从而防止胞外腺苷的水平过高(Clin.Invest.2012,122,693–710;Gastroenterology.2009,136,607–18)。然而,在肿瘤微环境中,细胞更新、组织破裂和局部缺氧都会将大量的ATP和腺苷释放到细胞周围环境中(Am.J.Physiol.1993,265,C577–606;Cancer Res.1997,57,2602–5)。此外,虽然部分胞外腺苷是在细胞应激时由胞内的ATP代谢转化产生和直接释放出的,胞外腺苷还能够通过外核苷酸酶CD39和CD73对胞外的ATP和ADP进行串联分解代谢产生。在肿瘤微环境中,CD39和CD73在许多类型的细胞上都有高表达,例如内皮细胞、基质细胞、肿瘤细胞,以及尤其是一些免疫细胞亚群,包括Tregs细胞、CD8+T细胞、B细胞、NK细胞、树突状细胞(DC)、髓源抑制细胞(MDSCs)和肿瘤相关巨噬细胞(TAMS)(CancerImmunol.Res.2014,2,598–605;Cancer Discov.2014,4,879–88;Clin.Cancer Res.2013,19,5626–35;J.Biomed.Biotechnol.2012,2012,485156)。其结果是,大量产生的胞外腺苷很难被正常吸收,从而导致胞外的腺苷水平过高(Am.J.Physiol.1993,265,C577–606;Cancer Res.1997,57,2602–5;Am.J.Physiol.1987,252,H886–93)。使用微透析探针进行的研究表明,实体瘤中的胞外腺苷水平比邻近组织高10-20倍,这么高的腺苷水平足以破坏免疫细胞的免疫功能(Cancer Res.1997,57,2602–5)。
研究也确实证明,胞外腺苷水平的升高和A2AR的激活具有广泛的免疫抑制作用(Cancer Res.2007,67,5949–56),包括免疫抑制细胞因子(TGF-beta and IL-10等)的大量产生(Blood.2008,111,251–9;Eur.J.Immunol.2010,40,682–7),其它免疫检查点通路受体(例如PD-1and LAG-3)的上调(Blood.2008,111,251–9;J.Immunol.2007,178,4240–9),Foxp3在CD4+T细胞上的表达上升,并因而增加其转变为调节性T细胞(Tregs)的程度,以及诱导效应性T细胞的免疫无能(Blood.2008,111,251–9)。由于Tregs具有更高的CD39和CD73表达量,当A2AR诱导的Foxp3表达上升将CD4+T细胞变为Tregs后,形成一个产生大量胞外腺苷的免疫抑制扩增信号回路,从而能够迅速地抑制免疫反应(J.Exp.Med.2007,204,1257–65)。最后,在A2AR信号传导的诱导下,CD8+效应细胞的细胞毒性变小,并更多地导致免疫无能(Blood 2008,111,251–9)。另外,除了抑制细胞毒性T细胞的功能外,增加的胞外腺苷还能下调肿瘤微环境中一系列免疫功能的活性,包括巨噬细胞、NK细胞、中性粒细胞和树突细胞的活性(Blood.2008,112,1822–31;Immunol Res.2006,36,91–9;Blood.2004,103,1391–7;Biochem.Pharmacol.2000,60,993–9;Am.J.Respir.Cell Mol.Biol.2009 40,251–9)。
鉴于腺苷信号传导在介导免疫反应的负反馈回路中的重要性,在肿瘤微环境中,对效应T细胞、Tregs、NK细胞、树突状细胞(DC)、骨髓源抑制细胞(MDSCs)和肿瘤相关巨噬细胞(TAMS)上的A2A受体的药物封阻可能能够抵消由腺苷所介导的免疫抑制作用,并在各个方面增强免疫反应,包括增强T细胞的激活、扩增和效应性功能。用小鼠进行的乙型肝炎和败血症模型的体内研究表明,在用基因或药物方式阻断A2AR通路以后,动物的炎症反应和组织伤害甚至能够达到失去控制的程度。这些研究中效应性T细胞增殖及其对肿瘤的杀伤能力均明显增强,证明了A2AR阻断剂的有效性。事实上,即使短时间的药物性A2AR封阻也能够增强免疫记忆能力,也能在初始抗原刺激几周后,还能够增强免疫功能。特别值得强调的是,其它的炎症控制机制并不能有效地补偿由于A2AR信号传导阻断而导致的组织损伤,因此,A2AR信号传导是一种十分关键的非冗余的免疫反应负反馈信号控制机制(Computational and Structural Biotechnology Journal.2015,13,265–272;CancerImmunol.Immunother.2012,61,917–26)。因此,对A2AR的药物阻断可望成为一种治疗癌症和其它类型异常细胞增殖的有效疗法。
本发明的目标是提供一种具有所希望的药学特性的新型A2AR拮抗剂。通过恢复或增强免疫反应,用本发明的A2AR拮抗剂能够有效地治疗和预防癌症以及其它类型的细胞异常增殖。

三唑并三嗪化合物的制备
本发明的另一个方面是可作为A2A受体拮抗剂的三唑并三嗪化合物的制备。本发明的三唑并三嗪化合物可以通过各种合成方法来制备。作为说明性的例子,合成路线(1)中列出了两种制备目标化合物的合成路线。在第一种方法中,在通过合适的制备方法得到中间体(1A)以后,用烷基氨基取代中间体(1A)上的甲磺酰基即得到三唑并三嗪化合物(1C)。在第二种方法中,在通过适当的方式得到中间体(1B)后,用烷基氨基取代中间体(1B)上的苯氧基也可得到三唑并三嗪化合物(1C)。
合成路线(1)中所需的中间体(1A)和(1B)也可以通过各种合成方法制备。作为说明性的例子,合成路线(2)中显示了中间体化合物(1A)的一种合成路线。在第一步,用适当的芳基酰肼(2A)与S-甲基异硫脲(2B)在氢氧化钠水溶液中反应后得到中间体(2C)。在后面的步骤中,先在水性介质中充分加热(2C)得到中间体(2D),中间体(2D)与N-氰基二硫代亚氨基碳酸酯(2E)反应后得到硫化物中间体(2F)。之后,用间氯过氧苯甲酸氧化中间体(2F)即得到所需的中间体砜(1A)。如合成路线(1)所示,用合适的烷基胺亲核取代甲基磺酰基就可得到目标化合物(1C)(J.Chem.Soc.,Perkin Trans.1 1995,801-808;StructuralChemistry.2013,24,1241–1251)。

合成路线(1)中的中间体(1B)可以用合成路线(4)所示的合成路线制备。制备首先从氰尿酰氯(4A)开始,在苯酚中回流得到2,4,6-三苯氧基-1,3,5-三嗪(4B)。下一步与水合肼反应后得到2-肼-4,6-二苯氧基-1,3,5-三嗪(4C),其与合适的酰氯反应后得到酰基酰肼(4D)。然后,酰肼(4D)在脱水条件下进行环化反应后得到2-取代的5,7-二苯氧基三唑并三嗪(4E),在最后一步,(4E)在甲醇氨中回流处理后就可得到关键的中间体(1B)(J.Chem.Soc.,Perkin Trans.1 1995,801-808)。如路线(1)所示,用合适的烷基胺与(1B)反应后即制成目标化合物(1C)。
癌症治疗
本发明的三唑并三嗪衍生物是腺苷A2AR拮抗剂,可用于治疗或预防与高活性腺苷A2A受体相关的疾病。例如,本发明的三唑并三嗪衍生物可以用于治疗帕金森氏病、认知或记忆障碍疾病和阿尔茨海默氏病等疾病。
除此之外,本发明的A2AR拮抗剂还可用于治疗或预防宿主的癌症及宿主中相关的细胞异常增殖,该宿主可以是任何多细胞脊椎动物,包括人类及非人类哺乳动物。所述宿主尤其是人类。
近年来,人们已深刻认识到淋巴细胞在肿瘤免疫中的重要性。机体对肿瘤的免疫反应包括免疫监测,在识别到肿瘤相关抗原后,这种与细胞介导的免疫有关的机制可以有效地清除新生成的肿瘤细胞。有细胞毒性免疫细胞,主要是T细胞,存在于神经母细胞瘤、恶性黑色素瘤、肉瘤,和结肠癌、乳腺癌、宫颈癌、子宫内膜癌、卵巢癌、睾丸癌、鼻咽癌和肾癌中。虽然抗体介导的抗癌作用也通常存在,但一般都比细胞免疫介导的抗癌作用小得多。
本发明的A2AR拮抗剂可用于提高宿主免疫细胞的抗肿瘤活性。所述A2AR拮抗剂能降低T细胞的免疫无能或T细胞对癌症的耐受,能使癌细胞更容易受到免疫清除,能抑制调节性T细胞的增殖,以及能够有助于记忆性T细胞的形成。本发明的A2AR拮抗剂既可以提高宿主自身具有的免疫反应,也可以提高其对各种适应性免疫疗法的功效。
在本发明的一个典型的实施方案中,治疗或预防细胞异常增殖的方法包括给患者施用有效剂量的式(1)所示的A2AR拮抗剂或其药学上可接受的盐或溶剂化物。
为了使之更加有效,本发明的A2AR拮抗剂还可以与其它癌症治疗方法(例如化学疗法、肿瘤疫苗及各种免疫检查点抑制剂)联合使用,从而实现协同效应。术语“联合治疗”指活性试剂的同时给药,也可以按不同顺序先后给药。
作为联合疗法的一个实例,治疗或预防宿主中细胞异常增殖的方法包括给患者联合施用或交替施用式(1)所示的A2AR拮抗剂和一种免疫检查点抑制剂。这里的免疫检查点抑制剂可以是PD-1抑制剂、PD-L1抑制剂、PD-L2抑制剂、CTLA-4抑制剂、BTLA抑制剂、LAG3抑制剂、TIM-3抑制剂、B7-H3抑制剂、B7-H4抑制剂、KIR抑制剂、TIGIT抑制剂或VISTA抑制剂等。
作为另一个实例,治疗或预防宿主中细胞异常增殖的方法包括给患者联合使用或交替施用式(1)所示的A2AR拮抗剂和一种细胞疫苗。所述细胞疫苗基于与要预防的肿瘤相匹配的细胞。例如,如果一个宿主患有前列腺癌,或者有患前列腺癌的风险,所述细胞疫苗将基于前列腺癌细胞。在这种情况下,通常是给所述细胞进行一定的放射性照射,或以其它方式使其失去复制功能。也可以通过对细胞进行基因改造使其能够分泌集落刺激因子。
作为另一个实例,治疗或预防细胞异常增殖的方法包括给患者联合施用或交替施用式(1)所示的A2AR拮抗剂和嵌合抗原受体CAR-T细胞疗法。
作为另一个实例,治疗或预防细胞异常增殖的方法包括给患者联合施用或交替施用式(1)所示的A2AR拮抗剂和一种其它抗癌药物以治疗细胞异常增殖。这种抗癌药物可以是烷基化试剂、抗代谢药物、蒽环类衍生物、植物生物碱、拓扑异构酶抑制剂、抗肿瘤抗生素、激酶抑制剂或抗肿瘤抗原的单克隆抗体等。
作为另一个实例,还可以将本发明的A2AR拮抗剂与两种或更多的其它抗癌方法(例如化疗、肿瘤疫苗和免疫检查点抑制剂)联合起来应用,来实现协同作用。术语“联合疗法”包括活性试剂的同时给药和顺序给药。
药物组合物
在给宿主用药时,本发明的三唑并三嗪衍生物可以配制成适当的药物组合物。药物组合物的具体组成由所选定的给药途径决定,给药途径包括口服、肠外道、静脉、肌肉内、鼻、口腔、局部、经皮或皮下。无论是用来治疗癌症,还是治疗其它以细胞异常增殖为特征的疾病,药物组合物中所含的三唑并三嗪衍生物的剂量应足以起到有效的治疗作用,同时不会给宿主带来严重的毒副作用。每天用药或每隔几天用药都可以,用药的时间可以持续数天、数周、数月、甚至数年。
口服是施用本发明的三唑并三嗪衍生物的很方便的方式。口服药物的成分通常包括惰性稀释剂或可食用载体。药物可封装于明胶胶囊中或压缩成片剂。药片、药丸、胶囊、锭剂以及其他剂型可含有以下成分:粘合剂如微晶纤维素、黄芪胶或明胶;辅料如淀粉或乳糖;崩解剂如海藻酸或玉米淀粉;润滑剂如硬脂酸镁;助流剂如胶质二氧化硅;甜味剂如蔗糖或糖精;调味剂如薄荷、水杨酸甲酯或橙子调味剂;润湿剂或乳化剂;防腐剂;以及pH缓冲剂等,如乙酸钠或山梨醇酐单月桂酸酯。当把药物组合物放在胶囊内时,其中还可以放入液体载体如脂肪油。此外,所述药物成分还可以包含各种其它材料,例如糖涂层、虫胶或其它的肠溶剂。
本发明的三唑并三嗪衍生物也可以以酏剂、悬浮液、糖浆、饼块、或口香糖等的组分施用。除了含有三唑并三嗪衍生物外,糖浆中还可以含有甜味剂如蔗糖、防腐剂、着色剂和调味剂等。用于肠道外的、皮肤内的、皮下的或局部的药物溶液或悬浮液可包括无菌稀释剂,如水、盐溶液、林格溶液、固定油、聚乙二醇、甘油、丙二醇、脂肪酸如油酸及其衍生物,或其它合成溶剂;抗菌剂如苄基醇或甲基对苯,抗氧化剂如抗坏血酸或亚硫酸钠,螯合剂如乙烯二胺四乙酸;缓冲剂如醋酸、柠檬酸或磷酸盐,以及张性或浸透压调节剂如氯化钠或葡萄糖等。药物原液可以装入安瓿,一次性的注射器,或由玻璃或塑料制成的多剂量的小瓶。
为了防止药物从体内快速清除,本发明的三唑并三嗪衍生物也可以放置在能够起到这种保护作用的载体中。也可应用其它各种能够控制药物释放速度的方法,例如使用植入物和微胶囊输送系统的方法。
本发明的三唑并三嗪衍生物也可以使用喷雾器、干粉吸入器、或定量喷雾吸入器等给药方式来实施给药。用这种方式给药的药物可以用盐水配制成溶液,并在其中加入苯甲醇或其它合适的防腐剂、吸收促进剂、碳氟化合物和其它常用的增溶或分散剂。
一般地说,对于一个患者而言,所要采用的治疗方案和给药剂量将取决于多种因素,包括所用的特定化合物的性能、患者的年龄、体重、一般健康状况、性别、饮食、给药时间、排泄率、病人的病理状况、治疗的目标和医生的判断。如果是联合治疗,活性成分的用量也会取决于使用哪种药物进行联合治疗。

A2A受体拮抗剂的生物活性
本发明的三唑并三嗪衍生物的拮抗活性用测量cAMP产生量的功能性试验测定。该方法包括,在表达有A2AR的HEK293细胞(hADORA2A-HEK293)中,NECA刺激的cAMP的产生和A2A受体拮抗剂对其的抑制作用。所有细胞均采用完全培养基,培养在5%CO2和37℃条件下进行。用胰酶消化细胞后,在200g离心5分钟收集细胞。再用新鲜完全培养基重悬细胞后采用台盼蓝排除法对细胞活力进行计数,仅当细胞活率大于95%时方可进行后续的cAMP产生测量实验。用含HEPES(5mM),BSA稳定剂(0.1%)和20Rolipram(10μM)的Hank's缓冲溶液稀释细胞后,将细胞加入384孔白色非透明板(~500细胞/孔,10μl/孔),并在室温下与合适浓度(11个浓度)的测试化合物孵育20分钟。然后将A2A受体激动剂NECA(最终浓度=EC80,该数值在稍早进行的同一实验中测定)添加到样品中,并在37℃下再次孵育30分钟。最后加入Eu-cAMP示踪剂和Ulight-anti-cAMP,通过测量665nm处的TR-FRET与615nm处的荧光发射的比值来确定cAMP的产生量。根据下式计算抑制率(%),根据从log转换后的浓度-抑制(%)曲线计算IC50值。
表(2)所示为代表性的本发明的三唑并三嗪衍生物的拮抗活性。
