本申请主张于2020年3月23日申请的美国临时申请第62/993,144号的权利,该临时申请全文并入本文中。
技术领域
本发明大体上涉及抑制Helios蛋白的经取代的氧代异吲哚啉化合物。本文提供经取代的氧代异吲哚啉化合物、包含所述化合物的组合物及其使用方法。本发明进一步关于适于治疗增生性病症(诸如癌症)及病毒感染的包含至少一种根据本发明的化合物的药物组合物。
背景技术
调节T细胞(Treg)经由在面对强烈免疫及炎症反应时,维持抑制活性及无能(anergy),在控制自体耐受性及免疫稳态中起重要作用。经由保持稳定、无能及抑制表型,Treg减弱过度免疫反应且阻止或改善自体免疫。许多报导已记录人类肿瘤组织内Treg的存在。研究证明Treg及T细胞浸润至肿瘤中的数目与存活率之间有明显负相关性(Curiel等人2004,Nat.Med.10:942-949;Viguier等人2004,J Immuno.1173:1444-1453;Beyer等人2006,Blood 108:804-811;Zou等人2006,Nat.Rev.Immunol.6:295-307),暗示Treg在阻止有效抗肿瘤免疫性的发展中的潜在关键作用。累积证据指示Foxp3+CD25+CD4+Treg主要浸润至肿瘤中且明显妨碍啮齿动物及人类中对肿瘤细胞的免疫反应。一旦经特异性抗原活化,Treg即以抗原非特异性及旁观者方式(bystander manner)体外抑制反应T细胞(Takahashi等人1998,Int Immunol.10:1969-80;Thornton等人1998,J Exp.Med.188:287-96)。Foxp3+CD25+CD4+Treg明显能够抑制涉及CD4+辅助T细胞、CD8+ T细胞、自然杀伤细胞及自然杀伤T细胞的广泛范围的抗肿瘤免疫反应(Tanaka等人2017,Cell Research 27:109-118)。CD25+CD4+Treg的瘤内耗竭引发已确立肿瘤消退,伴随肿瘤部位细胞因子环境发生变化(Yu等人2005,J Exp Med.201:779-91)。此外,相较于含有Treg的T细胞转移,Treg耗竭的CD4+ T细胞的转移明显地增强抗肿瘤免疫反应(Antony等人2005,J Immunol 174:2591-601)。由肿瘤来源的自体抗原或肿瘤相关抗原活化的肿瘤浸润性Treg可类似地抑制特异性抗肿瘤免疫反应。调节关键因子的活性以控制Treg分化可代表用于治疗某些疾病(包括癌症及病毒感染)的潜在治疗策略。
FoxP3+CD4 Treg非常稳定。研究仍在发展以了解在炎症、感染或自体免疫期间在扩增后确保其表型稳定性的基因机制。负责维持Treg的稳定免疫抑制表型的转录因子(TF)可能有助于此过程。Helios(IKZF2)基因(TF的Ikaros家族的成员)基于经历负向选择的胸腺细胞,以及CD4及CD8 T细胞的调节谱系的其选择性表达,不同于其他Ikaros家族成员。Helios由两种调节T细胞谱系FoxP3+CD4+及Ly49+CD8+ Treg表达,所述谱系对于维持自体耐受性必不可少(Kim等人2015,Science 350:334-339;Sebastian等人2016,JImmunol196:144-155)。引起关注地,近期研究表明,尽管Helios很大程度上对稳态下的Treg活性非必需,但在炎症情形下通过Helios控制FoxP3+CD4 Treg的基因程序对于维持稳定表型及增强抑制功能至关重要(Thornton等人2010,J Immunol.184:3433-3441;Kim等人2015)。Treg的Helios表达经证实对其在面对剧烈炎症反应时维持抑制及无能表型的能力至关重要。IL-2Rα-STAT5路径的活化经证实通过确保Treg存活及稳定性成为关键促成因素(Kim等人2015)。Helios通过在来自皮屑(scurfy)小鼠的高度活化自体反应性T细胞存在下发挥主要淋巴球固有抑制以预防自体免疫疾病而在维持FoxP3+CD4 Treg的表型方面发挥必不可少的作用,所述小鼠不具有FoxP3叉形头域。通过Helios-/-/皮屑BM而非Helios+/+/皮屑BM细胞重塑的骨髓(BM)嵌合体快速产生自体免疫性(Kim等人2015)。这些观测结果指示Helios对自体反应性T细胞选择、分化及功能的重要贡献。Treg施加的免疫抑制可妨碍抗肿瘤免疫反应。FoxP3+CD4 Treg中Helios的选择性缺乏引起增加的Treg不稳定性及瘤内CD4 Treg转化为效应T细胞(Teff)。瘤内Treg的不稳定性可因Treg转化及Treg抑制活性降低的组合作用而增加肿瘤内Teff细胞的数目。另外,在Helios缺乏型瘤内Treg中观测到缺陷性IL-2反应,其使得活化Treg的数目减少且亦可促进瘤内Teff活性增加。肿瘤细胞与浸润性免疫细胞之间的相互作用引起炎症介体,包括TNF-α、IL-6、IL-17、IL-1及TGF-β的分泌,及局部炎症环境形成(Kim等人2015)。
Helios缺乏型Treg的谱系不稳定性亦伴随着FoxP3表达减弱且通过产生促炎性细胞因子获得效应表型。肿瘤组织微环境内的Helios缺乏型Treg的效应细胞转化与控制Teff表型的基因的表达增加相关(Yates等人2018,PNAS,2018,115:2162-2167)。通过Helios缺乏获得不稳定表型仅在肿瘤微环境(TME)内发生,而不在周边淋巴器官中发生(Nakagawa等人2016,PNAS 113:6248-6253)。在慢性炎性TME内,Treg中的Helios缺乏可通过上调T辅助细胞相关TF及效应细胞因子大幅度缓解与T辅助细胞分化相关的经抑制基因程序。Helios缺乏型Treg的这些遗传变化在具有对自体抗原的高亲和力的Treg亚群中最明显,如通过增强的GITR/PD-1表达及增加的对自体抗原的反应性所示。其组合作用可促进TME内Treg表型转化成Teff,其中T细胞受体(TCR)接合及Treg共刺激受体表达增加,表明基因表达的变化作为Treg转化的中心特征为免疫环境依赖性的(Yates等人2018)。
FoxP3+CD4 Treg中降低的Helios表达可使得记忆Treg转化成表达特异性针对肿瘤抗原的自体反应性T细胞受体的Teff细胞。改变的Treg标记可在生长肿瘤的慢性炎症病状内选择性地诱发。Helios缺乏型Treg可呈现朝向针对自体肽/MHC的高亲和力偏向的TCR组库,其可促进TME中的稳固活化(Yates等人2018)。鉴于相比于常规T细胞,CD4 Treg中TCR增加的自体反应性,Treg的转化可产生高效效应CD4 T细胞,伴随着在TME内减弱的Treg介导的抑制。更有效策略可视在不影响全身Treg群体的情况下将瘤内Treg选择性地转化成Teff细胞的方法而定。作为响应于不同的免疫扰动维持Treg大小及功能性稳定性的关键参与者,Helios的药理学干预可与强化当前肿瘤免疫疗法的策略相关。因为Treg至Teff的转化可限于炎性瘤内微环境,所以靶向Helios的基于抗体或小分子的方法可产生改良的Treg依赖性癌症免疫疗法。重要的是,Helios缺乏型Treg的转化仅发生在肿瘤的局部炎症环境内。此方法可不引发与Treg的全身性减少相关的自体免疫副作用。因此,特异性利用瘤内Treg表型的Helios依赖性控制的策略代表改良癌症免疫疗法的重要前景。此外,亦报导移除Foxp3+Treg增强疫苗诱导的抗肿瘤T细胞反应(Nishikawa等人2010,Int.J.Cancer 127:759-767),表明减少Helios含量可有益于增强癌症疫苗的功效。
除抗肿瘤免疫疗法以外,在病毒感染期间,Treg细胞可限制由过度炎症产生的免疫病理学,但潜在地抑制有效抗病毒T细胞反应且促进病毒持久性(Schmitz等人2013,PLOSPathogens 9:e1003362)。慢性但非急性的小鼠淋巴球性脉络丛脑膜炎病毒感染引起Foxp3+ Treg的显著扩增,暗示某些感染物可通过活化及扩增Treg来逃避宿主免疫反应的潜在机制(Punkosdy等人2011,PNAS 108:3677-3682)。在与慢性病毒感染相关的情形下治疗益处可通过减少活化Treg中的Helios含量来达成。

制备方法
本发明化合物可以有机合成领域技术人员熟知的多种方式制备。本发明化合物可使用下述方法以及有机合成化学领域中已知的合成方法或如本领域技术人员所了解的其变化形式合成。优选方法包括但不限于以下所描述的方法。本文中所引用的所有参考文献均以全文引用的方式并入本文中。
本发明化合物可使用此章节中所描述的反应及技术来制备。反应在适于所用试剂及材料且适用于实现转化的溶剂中进行。另外,在下述合成方法的描述中,应了解所提出的所有反应条件(包括溶剂选择、反应氛围、反应温度、实验持续时间及处理程序)均选择本领域技术人员应可容易识别的该反应的标准条件。有机合成领域技术人员应了解,分子的各个部分上所存在的官能基必须与所提出的试剂及反应兼容。对与反应条件兼容的取代基的所述限制对于本领域技术人员而言将容易地显而易见,且于是必须使用替代方法。有时需要作出判断以修改合成步骤次序或选择一种特定方法流程而非另一种,从而获得本发明化合物。亦将认识到,在本领域中,任何合成途径的规划中的另一主要考虑因素为审慎选择用于保护本发明所述化合物中存在的反应性官能基的保护基。向经培训的从业者描述许多替代方案的权威性说明为Greene及Wuts(Protective Groups In Organic Synthesis,第四版,Wiley and Sons,207)。
式(I)化合物可通过参考以下流程中所说明的方法来制备。如其中所示,最终产物为结构式与式(I)相同的化合物。应理解,任何式(I)化合物可通过所述流程、通过在适当取代下适当选择试剂来制备。本领域普通技术人员可容易地选择溶剂、温度、压力及其他反应条件。起始材料可商购或易于由本领域普通技术人员制备。化合物的各成分如本文所定义或说明书中别处所定义。
本发明中所描述的化合物的一般途径说明于流程1-5中,其中R1及A取代基如前定义于本文中或为可转化成最终取代基的官能基。取代基L为离去基团,诸如卤离子(优选I、Br或Cl)或三氟甲磺酸根。取代基M为适合的偶合搭配物,诸如硼酸、硼酸酯或锡烷。取代基R为羧酸保护基,诸如叔丁基、甲基、乙基或苯甲基。如流程1中所示,制备本发明化合物的通用程序涉及以经适合取代的异吲哚啉酮1为起始物质。1的离去基团L可使用本领域普通技术人员所熟知的条件或本文所描述的方法转化为适合偶合搭配物M,得到中间体2。M为硼酸或硼酸酯的情况下,2可在适合的碱(例如碳酸铯、磷酸钾或碳酸氢钠)存在下,使用适合的钯催化剂(例如Pd(PPh3)4或1,1'-双(二苯基膦基)二茂铁]二氯钯(II))在铃木-宫浦偶合反应(Suzuki-Miyaura coupling reaction)中与经适合取代的杂环3结合,得到4。M为锡烷的情况下,2可使用适合催化剂系统(例如Pd(PPh3)4或双(三苯基膦)二氯钯(II)/CuI)在施蒂勒偶合反应(Stille coupling reaction)中与经适合取代的杂环3结合,得到4。中间体4可经由用诸如苯磺酸的质子酸处理而转化为5。或者,在一些情况下,4可通过用碱(例如K2CO3、K3PO4或LiHMDS)处理而转化成5。在一些情况下,中间体4可在用于制备其的铃木-宫浦偶合或施蒂勒偶合条件下自发环化成5。
流程1
在一些情况下,在合成顺序中更早偶合杂环A可是有利的。在所述情况下,6的离去基团L可使用本领域普通技术人员所熟知的条件或本文所描述的方法转化为适合偶合搭配物M,得到中间体7。M为硼酸或硼酸酯的情况下,7可在适合的碱(例如碳酸铯、磷酸钾或碳酸氢钠)存在下,使用适合的钯催化剂(例如Pd(PPh3)4或1,1'-双(二苯基膦基)二茂铁]二氯钯(II))在铃木-宫浦偶合反应中与经适合取代的杂环3结合,得到8。M为锡烷的情况下,7可使用适合催化剂系统(例如Pd(PPh3)4或双(三苯基膦)二氯钯(II)/CuI)在施蒂勒偶合反应中与经适合取代的杂环3结合,得到8。苯甲基甲基可在诸如光或AIBN的自由基引发剂存在下经由NBS的作用溴化,得到溴化物9。溴化物9可与3-氨基哌啶-2,6-二酮(10)在碱(例如二异丙基乙胺或三乙胺)存在下缩合,得到5。
流程2
或者,溴化物9可与11(其中R=叔丁基、甲基、乙基或苯甲基)在碱(例如二异丙基乙胺或三乙胺)存在下缩合,得到中间体12,如流程3中所示。在R=叔丁基的情况下,中间体12可通过流程1中所描述的方法进一步加工成化合物5。
流程3
视中间体12中的酸保护基R的特定选择而定,可能需要不同的条件将其转化成化合物5(流程4)。举例而言,在R=甲基、乙基或苯甲基的情况下,对于12直接转化为5,在适合溶剂(例如四氢呋喃)中使用适合碱(例如LiHMDS)进行12的碱诱导的环化可以是优选的。在R=叔丁基的情况下,对于12直接转化为5,在适合溶剂(例如乙腈)中使用适合酸(例如苯磺酸)进行12的酸诱导的环化可以是优选的。在一些情况下,可优选使用两步程序,首先使用适合于特定酸保护基R的条件释放游离羧酸13。所述方法为有机合成领域普通技术人员所熟知。举例而言,在R=叔丁基的情况下,使用适合酸(例如三氟乙酸或盐酸)的酸水解可以是优选的。在R=甲基、乙基或苯甲基的情况下,使用适合碱(例如LiOH)的碱性水解可以是优选的。在其他情况下,其中R=苯甲基,可有利地通过钯催化的氢解作用脱除保护基。一旦释放,13的羧酸可通过亚硫酰氯/二甲基甲酰胺或羰基二咪唑/二甲氨基吡啶的作用针对附挂伯酰胺的分子内攻击活化,得到5。
流程4
如前述流程中所示,经适合离去基团L取代的异吲哚啉酮为式(I)化合物的合成中的适用中间体。其可如流程5中所概述制备,其中L为诸如卤离子的离去基团。首先,中间体6的苯甲基甲基可在诸如光或AIBN的自由基引发剂存在下经由NBS的作用溴化,得到溴化物14。溴化物14可与3-氨基哌啶-2,6-二酮(10)在碱(例如二异丙基乙胺或三乙胺)存在下缩合,得到15。在一些情况下,有可能通过类似于1至4的转化的方法(流程1)来将中间体15转化为5。在其他情况下,可优选的为使溴化物14与中间体11缩合,得到16。中间体16可通过与流程1及流程4中所述类似的方法转化成5。
