Definitions

  • the present invention relates to a heterocyclic compound and its pharmaceutical composition, preparation method, intermediate and application.
  • Cyclin-dependent kinases belong to the serine/threonine kinase family.
  • the monomer itself is not active, and must be combined with the corresponding cyclins (Cyclins) to form active heterodimerization
  • the body complex plays a regulatory role and can catalyze the phosphorylation of the corresponding substrate, directly or indirectly regulate the cell to complete the cell cycle, and cause the growth and proliferation of the cell. It has been found that the human genome encodes 21 CDKs and more than 15 Cyclins. According to their different functions, CDKs can be divided into two categories: CDKs that control the cell cycle and CDKs that control cell transcription.
  • CDK 1/2/4/6 is mainly related to the cell cycle
  • CDK 7/8/9/10 is mainly related to the transcription mechanism of genetic information in the cell (Asghar U, Witkiewicz AK, Turner N C, et al. The history and future of targeting cyclin-dependent kinases in cancer therapy. Nat Rev Drug Discov, 2015(2): 130-146).
  • CDK7 is an important member of the CDKs family. It mainly regulates the cell cycle in two indirect ways: CDK7, cyclin H and Mat1 together form CAK (CDK activating kinase), which further phosphorylates CDK1/2, thereby activating them in Functions in the cell cycle (Yee A, Nichols MA, Wu L, Hall FL, Kobayashi R, Xiong Y. Molecular cloning of CDK7-associated human MAT1, a cyclin-dependent kinase-activating kinase (CAK) assembly factor.Cancer Res. 1995; 55:6058–6062).
  • CAK cyclin-dependent kinase-activating kinase
  • CDK7 is a subunit component of the universal transcription factor TFIIH to phosphorylate the large subunit carboxyl terminal domain (CTD) of RNA polymerase II (RNA polymerase II, RNAP II) to regulate the process of gene transcription in cells ( Kelso TW, Baumgart K, Eickhoff J, Albert T, Antrecht C, Lemcke S et al.Cyclin-dependentkinase 7controls mRNA synthesis by affecting stability of preinitiationcomplexes, leading to cell progression, cell Mol Cell Biol. 2014; 34: 3675-3688.). Since CDK7 has the dual functions of CAK and CTD phosphorylation, it plays an important role in cell proliferation, cell cycle and transcription.
  • CTD carboxyl terminal domain
  • CDK7 Inhibition of CDK7 can inhibit the expression of key oncogenes such as c-Myc (Chipumuro E, Marco E, Christensen CL, Kwiatkowski N, Zhang T, Hatheway CM, et al. CDK7inhibition suppresses super-enhancer-linked oncogenic transcription in MYCN-driven .Cell.2014,159:1126–39).
  • c-Myc Chipumuro E, Marco E, Christensen CL, Kwiatkowski N, Zhang T, Hatheway CM, et al. CDK7inhibition suppresses super-enhancer-linked oncogenic transcription in MYCN-driven .Cell.2014,159:1126–39).
  • CDK7 inhibitors may also be effective against cancers that have developed resistance to current treatment methods. Therefore, the development of CDK7 inhibitors will likely become an effective means of treating these malignant tumors.
  • the CDK7 inhibitors that have been reported include THZ1, Syros's compound SY-1365, and Carrick's compound CT7001, etc.
  • the structure is as follows:
  • Example 1 and Example 3 of Lilly's patent application WO2019099298A1 disclose two CDK7 inhibitors.
  • the compound structures are as follows:
  • the technical problem to be solved by the present invention is that the structure of the existing CDK7 inhibitor is relatively simple, so the present application provides a heterocyclic compound with a new structure and its pharmaceutical composition, preparation method, intermediate and application.

技术领域
本发明涉及一种杂环化合物及其药物组合物、制备方法、中间体和应用。
背景技术
细胞周期蛋白依赖性激酶(Cyclin-dependent kinases,CDKs)属于丝氨酸/苏氨酸激酶家族,其单体本身并不具有活性,必须与相应的细胞周期蛋白(Cyclins)结合形成有活性的异二聚体复合物发挥调节作用,可催化相应底物磷酸化,直接或间接调节细胞完成细胞周期,引起细胞的生长和增殖。目前已发现人类基因组编码21种CDKs和超过15种Cyclins。按其功能不同,CDKs可分为两大类:控制细胞周期的CDKs和控制细胞转录的CDKs。其中,CDK 1/2/4/6主要与细胞周期相关,而CDK7/8/9/10主要与细胞内遗传信息的转录机制相关(Asghar U,Witkiewicz A K,Turner N C,et al.The history and future of targeting cyclin-dependent kinases in cancer therapy.Nat Rev Drug Discov,2015(2):130-146)。
CDK7是CDKs家族的重要成员,主要通过两种间接的方式调控细胞周期:CDK7与cyclin H和Mat1一起组成CAK(CDK活化激酶,CDKs activating kinase),进一步使CDK1/2磷酸化,从而激活它们在细胞周期中的功能(Yee A,Nichols MA,Wu L,Hall FL,Kobayashi R,Xiong Y.Molecular cloning of CDK7-associated human MAT1,a cyclin-dependent kinase-activating kinase(CAK)assembly factor.Cancer Res.1995;55:6058–6062)。另外一种方式是CDK7作为通用转录因子TFIIH的亚基组成成分,磷酸化RNA聚合酶II(RNA polymerase II,RNAP II)的大亚基羧基末端结构域(CTD),调节细胞中基因转录过程(Kelso TW,Baumgart K,Eickhoff J,Albert T,Antrecht C,Lemcke S et al.Cyclin-dependent kinase 7controls mRNA synthesis by affecting stability of preinitiation complexes,leading to altered gene expression,cell cycle progression,and survival of tumor cells.Mol Cell Biol.2014;34:3675–3688.)。由于CDK7具备CAK和CTD磷酸化的双重功能,使其在细 胞增殖、细胞周期和转录过程都发挥重要的作用。
近年来,抑制CDK7逐渐成为多种癌症中有潜力的治疗策略。抑制CDK7能抑制关键致癌基因比如c-Myc等的表达(Chipumuro E,Marco E,Christensen CL,Kwiatkowski N,Zhang T,Hatheway CM,et al.CDK7inhibition suppresses super-enhancer-linked oncogenic transcription in MYCN-driven cancer.Cell.2014,159:1126–39)。临床前研究数据显示,抑制CDK7的小分子抑制剂在激素受体阳性和三阴性乳腺癌(Wang Y,Zhang T,Kwiatkowski N,Abraham BJ,Lee TI,Xie S,et al.CDK7dependent transcriptional addiction in triple-negative breast cancer.Cell.2015;163:174–86),以及受转录因子驱动的癌症如小细胞肺癌(SCLC)中有良好的抗癌效果(Christensen CL,Kwiatkowski N,Abraham BJ,Carretero J,Al-Shahrour F,Zhang T,et al.Targeting transcriptional addictions in small cell lung cancer with a covalent CDK7inhibitor.Cancer Cell 2014;26:909–22.)。这些癌症目前缺乏有效的治疗手段,有重大的未满足的医疗需求。并且,由于其作用机制不同,CDK7抑制剂对那些对目前的治疗方法已经产生抗药性的癌症可能也是有效的。因此,开发CDK7抑制剂将很有可能成为治疗这些恶性肿瘤的有效手段。
已报道的CDK7抑制剂有THZ1、Syros公司进入临床的化合物SY-1365、Carrick公司进入临床的化合物CT7001等。结构如下:

除非另外说明,本发明所使用的术语具有如下定义,下文中未涉及的术语的定义如本发明所属领域技术人员的通常理解。
术语“互变异构体”是指因分子中某一原子在两个位置迅速移动而产生的官能团异构体。例如,丙酮和1-丙烯-2-醇可以通过氢原子在氧上和α-碳上的迅速移动而互相转变。
术语“立体异构体”是指分子中原子或原子团相互连接次序相同,但空间排列不同而引起的异构体,例如顺反异构体、旋光异构体、阻转异构体等。这些立体异构体可以通过不对称合成方法或手性分离法(包括但不限于薄层色谱、旋转色谱、柱色谱、气相色谱、高压液相色谱等)分离、纯化及富集,还可以通过与其它手性化合物成键(化学结合等)或成盐(物理结合等)等方式进行手性拆分获得。旋光异构体包括对映异构体和非对映异构体。
术语“同位素衍生物”是指化合物中的一个或多个原子被一个或多个具有特定原子质量或质量数的原子取代。可以掺入化合物中的同位素的实例包括但不限于氢、碳、氮、氧、氟、硫和氯的同位素(例如 2H、 3H、 13C、 14C、 15N、 18O、 17O、 18F、 35S和 36Cl)。同位素化合物通常可以根据本文所述的方法通过用同位素标记的试剂取代非同位素标记的试剂来制备。同位素衍生物的典型实例包括氘代化合物。
术语“药学上可接受的盐”是指化合物与相对无毒的、药学上可接受的酸或碱制备得到的盐。当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药学上可接受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但不限于:锂盐、钠盐、钾盐、钙盐、铝盐、镁盐、锌盐、铋盐、铵盐、二乙醇胺盐。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药学上可接受的酸与这类化合物的中性形式接触的方式获得酸加成盐。所述的药学上可接受的酸包括无机酸,所述无机酸包括但不限于:盐酸、氢溴酸、氢碘酸、硝酸、碳酸、磷酸、亚磷酸、硫酸等。所述的药学上可接受的酸包括有机酸,所述有机酸包括但不限于:乙酸、丙酸、草酸、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、水杨酸、酒石酸、甲磺酸、异烟酸、酸式柠檬酸、油酸、单宁酸、泛酸、酒 石酸氢、抗坏血酸、龙胆酸、富马酸、葡糖酸、糖酸、甲酸、乙磺酸、双羟萘酸(即4,4’-亚甲基-双(3-羟基-2-萘甲酸))、氨基酸(例如谷氨酸、精氨酸)等。当化合物中含有相对酸性和相对碱性的官能团时,可以被转换成碱加成盐或酸加成盐。具体可参见Berge et al.,"Pharmaceutical Salts",Journal of Pharmaceutical Science 66:1-19(1977)、或、Handbook of Pharmaceutical Salts:Properties,Selection,and Use(P.Heinrich Stahl and Camille G.Wermuth,ed.,Wiley-VCH,2002)。
术语“晶型”是指其中的离子或分子是按照一种确定的方式在三维空间作严格周期性排列,并具有间隔一定距离周期重复出现规律;因上述周期性排列的不同,可存在多种晶型,也即多晶型现象。
