Abstract
本发明公开了一种藜芦胺类化合物、其制备方法及其应用。本发明提供了一种如式I所示的藜芦胺类化合物,可作为一系列新型AP‑1抑制剂并用于制备相应的疾病的药物。在初步活性研究中显示本发明提供的化合物具有很强的抑制肿瘤细胞增殖活性;具有制备成为新型抗肿瘤药物的潜力,具有较好的市场化前景。
Description
技术领域
本发明涉及一种藜芦胺类化合物、其制备方法及其应用。
背景技术
恶性肿瘤是严重威胁人类健康的疾病,其特征是异常细胞的克隆扩增,表现为增殖失控、对正常的稳态信号无反应、对邻近组织的侵袭和转移。恶性肿瘤细胞向重要器官的转移是成功治疗肿瘤的最大障碍,也是肿瘤病人死亡的最主要原因。目前,恶性肿瘤的治疗主要通过手术、化疗和放疗等方法。尽管在手术技术和化疗方面有了显著进步,但目前的医疗手段仍然不能治愈转移性癌症,开发新的治疗方法必须充分认识肿瘤转移的分子机制。
例如三阴性乳腺癌是一种严重威胁女性健康的疾病,目前治疗手段以化疗为主,毒副作用大且患者易产生耐药性,临床迫切需要开发有效的靶向疗法。
AP-1(activator protein-1,激活蛋白1)是细胞内的一个转录激活因子。它通过调节基因的表达来应对多种刺激,包括细胞因子,生长因子,压力,细菌和病毒感染;因此AP-1控制了许多的细胞进程,包括分化,增殖和凋亡。AP-1上调含有TPA DNA应答元件(TRE;5'-TGAG/CTCA-3')的基因的转录。AP-1异二聚体通过亮氨酸拉链形成,并通过特定的保守序列与基因结合来启动基因的表达。
AP-1在肿瘤的形成和发展中占有重要地位,其通过信号转导途径将生长信号转导到细胞核,导致多种细胞中涉及生长和恶性转化基因的过度表达,已成为肿瘤治疗及预防干预的重要靶标之一。研究发现,AP-1在多种恶性肿瘤如乳腺癌、肝细胞癌、皮肤癌、结直肠癌中高表达。虽然AP-1在多种癌症发生及发展过程中高表达,但是目前还没有以转录因子AP-1或其特定的DNA结合序列为靶点的抗肿瘤药物成功上市。
针对DNA短小核苷酸序列的药物设计是最有效也最具挑战性的设计策略,开发以DNA为靶点的AP-1抑制剂既可以推动癌症新靶点的研究,又可以进一步探索以DNA短小核苷酸序列为靶点的药物设计。
一系列体外实验表明,藜芦胺作用于AP-1的下游信号传导,但不干扰EGF诱导的胞质MAPK信号传导级联或其他与AP-1活化有关的激酶,表明基因调节仅发生在由AP-1控制的基因的子集上。动物试验表明,藜芦胺可抑制小鼠体内紫外线诱导的AP-1报告基因的激活,表明藜芦胺可以有效地预防太阳紫外线诱导的皮肤癌的发生,从而明确藜芦胺作为抗肿瘤候选药物的潜在价值

除非另外说明,应当应用本文所使用的下列定义。出于本发明的目的,化学元素与元素周期表CAS版,和《化学和物理手册》,第75版,1994一致。此外,有机化学一般原理可参考"Organic Chemistry",Thomas Sorrell,University Science Books,Sausalito:1999,和"March's Advanced Organic Chemistry”by Michael B.Smith and Jerry March,JohnWiley&Sons,New York:2007中的描述,其全部内容通过引用并入本文。
在本说明书中,可由本领域技术人员选择基团及其取代基以提供稳定的结构部分和化合物。当通过从左向右书写的常规化学式描述取代基时,该取代基也同样包括从右向左书写结构式时所得到的在化学上等同的取代基。
在本文中定义的某些化学基团前面通过简化符号来表示该基团中存在的碳原子总数。例如,C1-C6烷基是指具有总共1、2、3、4、5或6个碳原子的如下文所定义的烷基。简化符号中的碳原子总数不包括可能存在于所述基团的取代基中的碳。
在本文中,取代基中定义的数值范围如0至4、1-4、1至3等表明该范围内的整数,如1-6为1、2、3、4、5、6。
除前述以外,当用于本申请的说明书及权利要求书中时,除非另外特别指明,否则以下术语具有如下所示的含义。
术语“一种(个)或多种(个)”或“一种(个)或两种(个)以上”是指即1、2、3、4、5、6、7、8、9或更多。
术语“包括”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。
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,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。
一般而言,术语“取代的”表示所给结构中的一个或多个氢原子被具体取代基所取代。进一步地,当该基团被1个以上所述取代基取代时,所述取代基之间是相互独立,即,所述的1个以上的取代基可以是互不相同的,也可以是相同的。除非其他方面表明,一个取代基团可以在被取代基团的各个可取代的位置进行取代。当所给出的结构式中不只一个位置能被选自具体基团的一个或多个取代基所取代,那么取代基可以相同或不同地在各个位置取代。
在本说明书的各部分,本发明公开化合物的取代基按照基团种类或范围公开。特别指出,本发明包括这些基团种类和范围的各个成员的每一个独立的次级组合。术语“Cx-Cy烷基"是指含有x至y个碳原子的直链或支链饱和烃。例如,术语“C1~C6烷基”或“C1-6烷基”特别指独立公开的甲基、乙基、C3烷基、C4烷基、C5烷基和C6烷基;“C1-4烷基”特指独立公开的甲基、乙基、C3烷基(即丙基,包括正丙基和异丙基)、C4烷基(即丁基,包括正丁基、异丁基、仲丁基和叔丁基)。
术语“烯基”是指具有至少一个不饱和位置即碳-碳sp2双键的二到十二个碳原子的直链或支链的一价烃基(例如C2-C6烯基,又例如C2-C4烯基),并且包括具有“顺式”和“反式”取向或者“E”和“Z”取向的基团。其实例包括但不仅限于乙烯基、烯丙基、1-环戊-1-烯基、1-环戊-2-烯基、1-环戊-3-烯基、5-己烯基、1-环己-1-烯基、1-环己-2-烯基、和1-环己-3-烯基。
术语“卤素”选自于F,Cl,Br或I,尤其指F或Cl。
在本申请中,作为基团或是其它基团的一部分(例如用在卤素取代的烷基等基团中),术语“烷基”意指包括具有指定碳原子数目的支链和直链的饱和脂族烃基;比如含有1至6个碳原子的直链或支链饱和烃链;例如,C1-C6的烷基。如在“C1~C6烷基”中定义为包括在直链或者支链结构中具有1、2、3、4、5、或者6个碳原子的基团。其中,丙基为C3烷基(包括同分异构体,例如正丙基或异丙基);丁基为C4烷基(包括同分异构体,例如正丁基、仲丁基、异丁基或叔丁基);戊基为C5烷基(包括同分异构体,例如正戊基、1-甲基-丁基、1-乙基-丙基、2-甲基-1-丁基、3-甲基-1-丁基、异戊基、叔戊基或新戊基);己基为C6烷基(包括同分异构体,例如正己基、1-乙基-2-甲基丙基、1,1,2-三甲基丙基、1,1-二甲基丁基、1,2-二甲基丁基、2,2-二甲基丁基、1,3-二甲基丁基、2-乙基丁基、2-甲基戊基、3-甲基戊基、4-甲基戊基、2,3-二甲基丁基)。在某一实施方案中,所述的“烷基”是指C1~C4烷基。
本文所用术语“部分”、“结构部分”、“化学部分”、“基团”、“化学基团”是指分子中的特定片段或官能团。化学部分通常被认为是嵌入或附加到分子上的化学实体。
当所列举的取代基中没有指明其通过哪一个原子连接到化学结构通式中包括但未具体提及的化合物时,这种取代基可以通过其任何原子相键合。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。
当所列举的基团中没有明确指明其具有取代基时,这种基团仅指未被取代。例如当“C1~C4烷基”前没有“取代或未取代的”的限定时,仅指“C1~C4烷基”本身或“未取代的C1~C4烷基”。
在本发明的各部分,描述了连接取代基。当该结构清楚地需要连接基团时,针对该基团所列举的马库什变量应理解为连接基团。例如,如果该结构需要连接基团并且针对该变量的马库什基团定义列举了“烷基”,则应该理解,该“烷基”代表连接的亚烷基基团。
在一些具体的结构中,当烷基基团清楚地表示为连接基团时,则该烷基基团代表连接的亚烷基基团,例如,基团“卤代-C1~C6烷基”中的C1-C6烷基应当理解为C1~C6亚烷基。
术语“亚烷基”表示从饱和的直链或支链烃基中去掉两个氢原子所得到的饱和的二价烃基基团。亚烷基基团的实例包括亚甲基(-CH2-),亚乙基{包括-CH2CH2-或-CH(CH3)-},亚异丙基{包括-CH(CH3)CH2-或-C(CH3)2-}等等。
除非另有规定,本文使用的所有技术术语和科学术语具有要求保护主题所属领域的标准含义。倘若对于某术语存在多个定义,则以本文定义为准。
应该理解,在本发明中使用的单数形式,如“一种”,包括复数指代,除非另有规定。此外,术语“包括”是开放性限定并非封闭式,即包括本发明所指明的内容,但并不排除其他方面的内容。
除非另有说明,本发明采用质谱、元素分析的传统方法,各步骤和条件可参照本领域常规的操作步骤和条件。
除非另有指明,本发明采用分析化学、有机合成化学和光学的标准命名及标准实验室步骤和技术。在某些情况下,标准技术被用于化学合成、化学分析、发光器件性能检测。
另外,需要说明的是,除非以其他方式明确指出,在本发明中所采用的描述方式“…独立地为”应做广义理解,是指所描述的各个个体之间是相互独立的,可以独立地为相同或不同的具体基团。更详细地,描述方式“…独立地为”既可以是指在不同基团中,相同符号之间所表达的具体选项之间互相不影响;也可以表示在相同的基团中,相同符号之间所表达的具体选项之间互相不影响。
本领域技术人员可以理解,根据本领域中使用的惯例,本申请描述基团的结构式中所使用的是指,相应的基团通过该位点与化合物中的其它片段、基团进行连接。
在不违背本领域常识的基础上,上述各优选条件,可任意组合,即得本发明各较佳实例。
本发明所用试剂和原料均市售可得。
