Definitions

  • the present invention relates to the field of medical technology, in particular to compounds used as CDK7 kinase inhibitors, and their applications in regulating CDK7 kinase activity or treating CDK7-related diseases, especially cancer.
  • Cyclin-dependent kinases (Cyclin-dependent kinases) belong to the serine/threonine kinase family, which play physiological functions by combining with the corresponding cyclins (Cyclins) to form active dimer complexes, causing cell growth. and added value.
  • CDKs regulating cell cycle
  • CDKs regulating cell transcription among which CDKs 1-6 and 14-18 are involved in the regulation of cell cycle, CDKs 7-13 and 19 -20 is involved in transcriptional regulation of cells.
  • CDK7 is an important member of the CDKs family, and its main physiological function is to regulate cell cycle and transcription.
  • CDK7 forms CAK (CDKs activating kinase) together with cyclin H and Mat1, and participates in the regulation of cell cycle by phosphorylating CDK1/2/4/6.
  • CDK7 as a component of the universal transcription factor TFIIH (Transcription factor II human), phosphorylates the CTD domain (carboxy-terminal) of RNA polymerase II (RNA polymerase II) in the most important initial stage of gene transcription. domain), involved in the gene transcription process of cells.
  • TFIIH Transcription factor II human
  • CDK7 Due to the dual unique functions of CDK7 in transcription and cell cycle progression, it is widely expressed in various types of cancer, and down-regulation of CDK7 activity can lead to a reduction in cell proliferation. More importantly, it is now agreed that targeted transcription selectively restricts the synthesis of mRNAs involved in tumor growth without causing disruption of the transcription of housekeeping genes. Therefore, CDK7 is considered to be a feasible and very promising target for tumor therapy, which has attracted extensive attention, and many small molecules, such as THZ1, THZ2, CT7001, SY-1365, etc., have shown great promise in preclinical studies. Good effect of inhibiting tumor growth. Especially in the areas of unmet major diseases that currently lack effective treatments, such as small cell lung cancer, triple-negative breast cancer, and pancreatic cancer. Therefore, the development of specific CDK7 inhibitors is expected to be used in the above clinical unmet areas.

Abstract

本发明涉及用作CDK7激酶抑制剂的化合物及其应用。具体地,本发明化合物具有式I所示结构,其中各基团和取代基的定义如说明书中所述。本发明的化合物可用作细胞周期蛋白依赖性激酶7(CDK7)的抑制剂,用于增殖性疾病(如癌症)的治疗或预防,尤其是用于调节和治疗与细胞周期蛋白依赖性激酶7(CDK7)的异常活性所导致的相关疾病。

Description

用作CDK7激酶抑制剂的化合物及其应用 技术领域
本发明涉及医药技术领域,具体涉及用作CDK7激酶抑制剂的化合物,及其在调节CDK7激酶活性或治疗CDK7相关疾病,尤其癌症方面的应用。
背景技术
细胞周期蛋白依赖性激酶CDKs(Cyclin-dependent kinases)属于丝氨酸/苏氨酸激酶家族,其通过与相应的细胞周期蛋白(Cyclins)结合形成活性的二聚体复合物发挥生理功能,引起细胞的生长和增值。目前已发现20多种CDKs,按照其功能分为两大类:调控细胞周期的CDKs和调控细胞转录的CDKs,其中CDKs 1-6和14-18参与细胞周期的调控,CDKs 7-13和19-20参与细胞的转录调控。
CDK7是CDKs家族的重要成员,主要的生理功能是调控细胞周期和转录。在细胞液中,CDK7与cyclin H和Mat1一起组成CAK(CDKs activating kinase),通过磷酸化CDK1/2/4/6,参与细胞周期的调控。在细胞核内,CDK7作为通用转录因子TFⅡH(Transcription factor Ⅱ human)的组成部分,在基因转录最重要的起始阶段,通过磷酸化RNA聚合酶Ⅱ(RNA polymerase Ⅱ)的CTD结构域(carboxy-terminal domain),参与细胞的基因转录过程。由于CDK7具有CAK和CTD磷酸化的双重功能,所以,其在细胞增殖、细胞周期和基因转录过程中都发挥着重要的作用。
由于CDK7在转录和细胞周期进程中的双重独特作用功能,其在各种类型的癌症中广泛表达,通过下调CDK7的活性可以导致细胞增殖的减少。更重要的是,现在人们一致认为,靶向转录可选择性的限制参与肿瘤生长的mRNA的合成,而不会导致管家基因(housekeeping genes)转录的中断。因此,CDK7被认为是一个可行的、非常有前途的肿瘤治疗靶点,引起了广泛关注,其中很多小分子,如THZ1、THZ2、CT7001、SY-1365等,在临床前的研究中表现出非常好地抑制肿瘤生长的效果。尤其是在小细胞肺癌、三阴乳腺癌、胰腺癌等目前缺乏有效治疗手段的未满足的重大疾病领域。因此,开发特异性的CDK7抑制剂有望用于以上临床未满足领域。

本发明提供了一种新的具有CDK7激酶抑制活性的、具有更好药效学、药代动力学性能的化合物。

本发明中化合物的前药及溶剂合物(或溶剂化物)也在涵盖的范围之内。
此处术语“前药”是指一种化合物,在治疗相关疾病时,经过代谢或化学过程的化学转化而产生本发明中的化合物、盐、或溶剂合物。本发明的化合物包括溶剂合物,如水合物。
本发明中的化合物、盐或溶剂合物,可能存在的互变异构形式(例如酰胺和亚胺醚)。所有这些互变异构体都是本发明的一部分。
所有化合物的立体异构体(例如,那些由于对各种取代可能存在的不对称碳原子),包括其对映体形式和非对映形式,都属于本发明的设想范围。本发明中的化合物独立的立体异构体可能不与其他异构体同时存在(例如,作为一个纯的或者实质上是纯的光学异构体具有特殊的活性),或者也可能是混合物,如消旋体,或与所有其他立体异构体或其中的一部分形成的混合物。本发明的手性中心有S或R两种构型,由理论与应用化学国际联合会(IUPAC)1974年建议定义。外消旋形式可通过物理方法解决,例如分步结晶,或通过衍生为非对映异构体分离结晶,或通过手性柱色谱法分离。单个的光学异构体可通过合适的方法由外消旋体得到,包括但不限于传统的方法,例如与光学活性酸成盐后再结晶。
本发明中的化合物,依次通过制备、分离纯化获得的该化合物其重量含量等于或大于90%,例如,等于或大于95%,等于或大于99%(“非常纯”的化合物),在正文描述列出。此处这种“非常纯”本发明的化合物也作为本发明的一部分。
本发明的化合物所有的构型异构体都在涵盖的范围之内,无论是混合物、纯的或非常纯的形式。在本发明化合物的定义包含顺式(Z)和返式(E)两种烯烃异构体,以及碳环和杂环的顺式和反式异构体。
在整个说明书中,基团和取代基可以被选择以提供稳定的片段和化合物。
特定官能团和化学术语定义都详细介绍如下。对本发明来说,化学元素与 Periodic Table of the Elements,CAS version,Handbook of Chemistry and Physics,75 th Ed.中定义的一致。特定官能团的定义也在其中描述。此外,有机化学的基本原则以及特定官能团和反应性在“Organic Chemistry”,Thomas Sorrell,University Science Books,Sausalito:1999,也有说明,其全部内容纳入参考文献之列。
本发明的某些化合物可能存在于特定的几何或立体异构体形式。本发明涵盖所有的化合物,包括其顺式和反式异构体、R和S对映异构体、非对映体、(D)型异构体、(L)型异构体、外消旋混合物和其它混合物。另外不对称碳原子可表示取代基,如烷基。所有异构体以及它们的混合物,都包涵在本发明中。
按照本发明,同分异构体的混合物含有异构体的比率可以是多样的。例如,在只有两个异构体的混合物可以有以下组合:50:50,60:40,70:30,80:20,90:10,95:5,96:4,97:3,98:2,99:1,或100:0,异构体的所有比率都在本发明范围之内。本专业内一般技术人员容易理解的类似的比率,及为更复杂的异构体的混合物的比率也在本发明范围之内。
本发明还包括同位素标记的化合物,等同于原始化合物在此公开。不过实际上对一个或更多的原子被与其原子量或质量序数不同的原子取代通常会出现。可以列为本发明的化合物同位素的例子包括氢、碳、氮、氧、磷、硫、氟和氯同位素,分别如 2H、 3H、 13C、 11C、 14C、 15N、 18O、 17O、 31P、 32P、 35S、 18F和 36Cl。本发明中的化合物,或对映体,非对映体,异构体,或药学上可接受的盐或溶剂化物,其中含有上述化合物的同位素或其他同位素原子都在本发明的范围之内。本发明中某些同位素标记化合物,例如 3H和 14C的放射性同位素也在其中,在药物和底物的组织分布实验中是有用的。氚,即 3H和碳-14,即 14C,它们的制备和检测比较容易。是同位素中的首选。此外,较重同位素取代如氘,即 2H,由于其很好的代谢稳定性在某些疗法中有优势,例如在体内增加半衰期或减少用量,因此,在某些情况下可以优先考虑。同位素标记的化合物可以用一般的方法,通过用易得的同位素标记试剂替换为非同位素的试剂,用批露在示例中的方案可以制备。
如果要设计一个本发明的化合物特定的对映体的合成,它可以不对称合成制备,或用手性辅剂衍生化,将所产生的非对映混合物分离,再除去手性辅剂而得到纯的对映体。另外,如果分子中含有一个碱性官能团,如氨基酸,或酸性官能团, 如羧基,可以用合适的光学活性的酸或碱的与之形成非对映异构体盐,再通过分离结晶或色谱等常规手段分离,然后就得到了纯的对映体。
如本文所述,本发明中的化合物可与任何数量取代基或官能团取而扩大其包涵范围。通常,术语“取代”不论在术语“可选”前面或后面出现,在本发明配方中包括取代基的通式,是指用指定结构取代基,代替氢自由基。当特定结构中的多个在位置被多个特定的取代基取代时,取代基每一个位置可以是相同或不同。本文中所使用的术语“取代”包括所有允许有机化合物取代。从广义上讲,允许的取代基包括非环状的、环状的、支链的非支链的、碳环的和杂环的,芳环的和非芳环的有机化合物。在本发明中,如杂原子氮可以有氢取代基或任何允许的上文所述的有机化合物来补充其价态。此外,本发明是无意以任何方式限制允许取代有机化合物。本发明认为取代基和可变基团的组合在以稳定化合物形式在疾病的治疗上是很好的。此处术语“稳定”是指具有稳定的化合物,在足够长的时间内检测足以维持化合物结构的完整性,最好是在足够长的时间内都在效,本文在此用于上述目的。
本申请所涉及的化合物及其药学可接受的盐的代谢产物,以及可以在体内转变为本申请所涉及的化合物及其药学可接受的盐的结构的前药,也包含在本申请的权利要求中。
在另一优选例中,所述的化合物中,各基团中任一个分别为所述具体化合物中所对应的基团。
