Abstract
Description
技术领域
本发明涉及一种吡咯并吡啶酮类化合物或其药学上可接受的盐,其制备方法、及其组合物用于治疗与该靶点相关的肿瘤疾病等的药物用途。
背景技术
组蛋白赖氨酸残基的乙酰化被认为是转录活性基因的标志(参见非专利文献1)。一方面,赖氨酸乙酰化可以中和其正电荷,导致组蛋白对带负电荷的DNA的亲和力降低或使核小体的结构变得松散,最终形成一个开放的、可进入的染色质结构,能够招募转录因子。另一方面,乙酰化赖氨酸为蛋白识别模块提供了结合位点。组蛋白赖氨酸残基的乙酰化和去乙酰化主要由组蛋白乙酰化酶(histone acetylase,HATs)和组蛋白去乙酰化酶(histone deacetylases,HDACs)控制。而组蛋白上的乙酰化能够特异的被溴结构域蛋白(bromodomains,BRDs)识别,招募染色质调节相关蛋白、转录因子、染色质重塑因子等,从而在调控基因转录和染色质重塑中发挥重要作用(参见非专利文献2)。
溴结构域蛋白(bromodomains,BRDs)按照结构和序列相似性可以被分为8个家族。其中,溴结构域和超末端结构蛋白(bromodomain and extra-terminal Domain,BET)家族属于BRD家族中的第二类,包括BRD2、BRD3、BRD4以及BRDT。BET蛋白能够识别乙酰化的组蛋白,招募转录因子和转录延长因子等,调控细胞的转录和细胞周期,在多种疾病尤其是肿瘤、炎症中扮演着重要的角色(参见非专利文献3)。BRD4作为该家族中主要的成员,与转录调控和肿瘤的发生等密切相关(参见非专利文献4)。许多调节癌细胞增殖、抗凋亡和侵袭性的癌基因都受BRD4调控,其中c-Myc作为第一个被报道的在血液瘤和实体瘤中受BRD4调控的致癌基因,为BET蛋白抑制剂的开发提供了理论依据(参见非专利文献5、6)。还有一些其他的致癌基因例如FOSL1(FRA-1)、BCL-2、RUNX2、c-KIT等受BRD4调控(参见非专利文献7-10)。此外,BRD4已被证明可以调控与修复受损DNA相关的分子机制,并与癌症中异常的端粒调控有关,这突出了这种蛋白在癌症发生过程中的功能多样性作用(参见非专利文献11、12)。
目前,已经发展出了有多种结构类型的BET抑制剂,例如I-BET 762,JQ1,I-BET151,OTX-015,TEN-010,ZEN003694,GS-5829,CPI-0610,ABBV-075,ABBV-744等,被广泛应用于血液瘤、实体瘤和心血管疾病等的研究。该类抑制剂的早期临床研究虽然能够有取得短暂的治疗效果,但是也存在一些毒副作用,例如严重的血小板减少、疲劳、恶心、呕吐和腹泻等胃肠道副作用等(参见非专利文献13)。
HDACs的作用使组蛋白去乙酰化,令组蛋白和DNA的结合更为紧密,从而抑制基因的表达。目前研究表明,HDAC能够影响细胞周期、细胞凋亡、DNA损伤相应、癌细胞转移、血管生成、自噬和其他细胞进程,在肿瘤进程中扮演至关重要的角色(参见非专利文献14)。HDAC的抑制会引起组蛋白总体乙酰化水平的改变,尤其是缺乏乙酰化或者低密度乙酰化区域(参见非专利文献15-17)。而整个基因组中乙酰化的重新分布能够影响BET蛋白的募集,使其从调控区域转移到新的乙酰化位点,使BET蛋白的促进转录功能作用降低。因此,HDAC和BET蛋白通过基因组乙酰化谱可能存在着一些直接或者间接的相互作用(参见非专利文献18)。例如癌细胞生长中心超级增强子依赖于BRD4蛋白,因此BET抑制剂能够优先抑制癌细胞依赖的癌基因转录(参见非专利文献4);而HDAC抑制剂能使组蛋白和其他转录调节因子的乙酰化水平升高,这能够诱导RNA聚合酶Ⅱ的延长暂停,从而优先抑制高表达的致癌扩增子(参见非专利文献16)。此外BRD4蛋白具有组蛋白分子伴侣的功能,能够协助RNA聚合酶Ⅱ通过乙酰化的核小体,而HDAC通过去除组蛋白或者其他蛋白上的乙酰化,改变BRD4在组蛋白在核小体和染色质相关蛋白复合物的结合(参见非专利文献19)。
许多临床前研究表明,HDAC和BRD4抑制剂能够在多种肿瘤细胞中表现出协同作用,而且这种药物联用能够在较低的剂量下达到较高的细胞毒性,从而可能避免叠加毒性的问题。例如在c-Myc诱导的淋巴瘤小鼠中,BET抑制剂能够部分敏化由HDAC沉默基因诱导的c-Myc过表达淋巴瘤细胞,而BET抑制剂RVX2135和HDAC抑制泛剂SAHA联用对淋巴瘤移植小鼠的无进展生存期具有协同作用(参见非专利文献20)。在成神经细胞瘤和极性骨髓性白血病细胞系中,帕比司他和JQ1联合治疗相比单独用药能够更有效的诱导细胞凋亡和生长抑制,而治疗对正常细胞没有显著影响,且能够阻止肿瘤生长,提高移植瘤小鼠的存活率(参见非专利文献21、22)。同样,JQ1与SAHA联用在胰腺导管癌(PDAC)的体内外模型中都能够产生有效且持续的抗肿瘤效果(参见非专利文献23);在尿路上皮癌细胞系中,JQ1和罗米地辛联用显示出协同作用(参见非专利文献24);帕比司他和I-BET151联合使用可强烈诱导黑色素瘤细胞系和对BRAFi耐药的黑色素瘤患者的细胞凋亡和细胞周期阻滞(参见非专利文献25);panobinostat和OTX-015能够抑制胶质母细胞瘤细胞的增殖,增强caspase介导的凋亡,尤其是抑制磷酸化和糖酵解,导致细胞出现能量危机和严重的应激反应(参见非专利文献26)。
这些研究证明了HDAC和BRD4抑制剂联合治疗的有效性,而将HDAC和BRD4抑制剂活性基团结合到同一个分子中,可开发出一类新型更为有效的双靶小分子药物,同时能够表观遗传机制研究提供新型的工具分子,目前尚没有吡咯并吡啶酮类HDAC和BRD4双靶抑制剂小分子的报道。
近年来还发展出一种利用蛋白水解靶向嵌合分(Proteolysis TargetingChimeras,PROTACs)技术设计合成的双功能小分子,能够将BRD4蛋白和细胞内的E3拉近,从而导致目标蛋白的降解。和传统的抑制剂相比,该类双功能小分子能够更加有效的抑制肿瘤细胞的生长,促进其凋亡(参见非专利文献27)。发展能够靶向泛素化降解BRD4蛋白的双功能小分子在研究BRD4蛋白的功能以及新型抗肿瘤药物的研发中具有重要意义(参见非专利文献28),目前上没有基于吡咯并吡啶酮类结构母核的BRD4泛素化降解小分子的报道。

由图可知,实施例84和80化合物能够剂量依赖的上调组蛋白H3的乙酰化水平,但是对微管蛋白的乙酰化水平影响不大,其作用效果和HDAC1选择性抑制剂MS275相当,说明该类化合物是HDAC1选择性抑制剂;同时化合物能够剂量依赖的下调c-Myc的表达,作用效果和BRD4抑制剂ABBV-744类似。
实施例96化合物能够同时剂量依赖的上调组蛋白H3和微管蛋白的乙酰化水平,与泛HDAC抑制剂SAHA作用效果类似,说明该化合物具有泛HDAC抑制活性。同时该化合物能够剂量依赖的下调c-Myc的表达,作用效果和BRD4抑制剂ABBV-744类似。
实施例100化合物能够剂量依赖的上调微管蛋白的乙酰化水平,但是对组蛋白H3乙酰化水平影响不大,其作用效果和选择性HDAC6抑制剂ACY1215类似,说明该化合物具有一定的HDAC6选择性抑制活性。同时该化合物能够剂量依赖的下调c-Myc的表达,作用效果和BRD4抑制剂ABBV-744类似。
综上所述,通过在MV-4-11细胞株上免疫印迹实验,证明实施例84和80化合物是选择性HDAC1和BRD4双靶抑制剂,实施例96化合物是泛HDAC和BRD4双靶抑制剂,实施例100化合物是选择性HDAC6和BRD4双靶抑制剂。
