Definitions

  • the invention belongs to the technical field of polycyclic amide derivatives, and specifically relates to a polycyclic amide derivative as a CDK9 inhibitor, a preparation method and application thereof.
  • CDKs Cell cycle-dependent protein kinases
  • CDKs are a class of serine/threonine kinases that play a key role in cell cycle regulation and cell transcription. They are increasingly used as important targets for the treatment of cancer and other diseases. s concern.
  • the CDKs family has 13 different subtypes with similar structures, which can be activated by about 10 cyclins to perform different biological functions. According to different mechanisms of action, it is generally divided into cell cycle CDK (CDK1-6) and transcriptional CDK (CDK7-9).
  • CDK9 is mainly involved in the process of transcription regulation.
  • the heterodimer composed of CDK9 and cyclin (T1, T2a, T2b, K) participates in the formation of positive transcription elongation factor (P-TEFb), which plays a key role in the process of transcription regulation.
  • CDK9 has a classic protein kinase fold, consisting of C-terminal and N-terminal kinase domains and a small C-terminal extension.
  • P-TEFb positive transcription elongation factor
  • CDK9 participates in the elongation process of transcription and plays an important role in the transcription process.
  • CDK9 regulates the RNA transcription of short-lived anti-apoptotic proteins
  • CDK9 regulates the expression of anti-apoptotic proteins by phosphorylating RNApol II.
  • RNApol II The transcription catalyzed by RNApol II is a multi-step process.
  • the C-terminal domain of RNApol II large subunit contains the tandem heptapeptide repeat sequence.
  • the phosphorylation of Ser and Thr plays an important role in the transcription process.
  • CDK9 in the P-TEFb complex phosphorylates Ser at 2 of RNApol II CTD, it also phosphorylates sensitive inducible factor DSIF and negative elongation factor NELF. Phosphorylation causes NELF to leave and at the same time converts DSIF into a positive transcription factor. Then RNApol II enters the transcription elongation mode, and the transcription elongation process starts 1 .
  • CDK9 Inhibition of CDK9 will lead to the down-regulation of anti-apoptotic proteins Mcl-1, XIAP, etc., so that these anti-apoptotic proteins lose their ability to maintain the stability of tumor cells, thereby inducing tumor cell apoptosis.
  • CDK9 is also involved in the regulation of many cell functions. Selective inhibition of CDK9 can also be used as a potential treatment strategy for tumor invasion and metastasis. Recently, it has also been reported that CDK9 inhibitors can down-regulate MYC protein by inhibiting transcription and post-transcriptional modification, and therefore have an inhibitory effect on MYC-driven tumors 2 .
  • CDK9 can increase the number of CD45 + cells in the tumor environment, increase the proportion of CD3 + T cells and activate dendritic cells. Therefore, combined with CDK9 inhibitors can enhance the immune response of tumor immune checkpoint inhibitors (checkpoint blockage) 3 .
  • CDK is an important target for the treatment of tumors and other diseases.
  • many CDK inhibitors have entered the clinic, and selective CDK4/6 inhibitors have been marketed, which brings confidence and hope for the development of selective CDK inhibitors.
  • CDK9 as a novel and huge potential anti-tumor drug target, has received more and more attention.
  • a number of selective CDK9 inhibitors have entered the clinic (Fadraciclib, Zotitraciclib, KB-130742 and AZD-4573, etc.), with CDK9 as the target Anti-tumor drug targets have broad application prospects.
  • CDK9 inhibitors can be roughly divided into flavonoids, pyrimidines, pyridines, phenyltriazines and other categories according to their core structure. Some of these CDK9 inhibitors are highly selective for CDK9 (WO2017001354, WO2018192273, WO2019154177, etc.).

Description

一种作为CDK9抑制剂的多环酰胺类衍生物、其制备方法及用途 技术领域
本发明属于多环酰胺类衍生物技术领域,具体涉及一种作为CDK9抑制剂的多环酰胺类衍生物、其制备方法及用途。
背景技术
细胞周期依赖蛋白激酶(CDKs)是一类丝氨酸/苏氨酸激酶,在细胞周期调节及细胞转录过程中起着关键的作用,其作为治疗癌症和其他一些疾病的重要靶点受到越来越多的关注。CDKs家族共有13个结构类似的不同亚型,可以被10个左右的细胞周期蛋白激活,发挥不同的生物学功能。根据作用机制不同,一般分为细胞周期性CDK(CDK1-6)和转录性CDK(CDK7-9)。CDK9主要参与转录调控过程,由CDK9和cyclin(T1、T2a、T2b、K)组成的异源二聚体参与组成正性转录延长因子(P-TEFb),在转录调控过程中发挥关键作用。CDK9具有经典的蛋白激酶折叠,由C-端和N-端激酶域及一个小的C-端延伸区组成。CDK9作为P-TEFb的亚单位参与转录的延长过程,在转录过程中发挥重要作用。CDK9调控短寿命抗凋亡蛋白的RNA转录,CDK9通过磷酸化RNApol II来调控抗凋亡蛋白的表达。由RNApol II所催化的转录是一个多步骤过程。RNApol II大亚基的C端结构域包含串联的七肽重复序列上的Ser和Thr的磷酸化在转录过程中起重要作用。P-TEFb复合物中的CDK9磷酸化RNApol II CTD 2位Ser的同时,也会磷酸化敏感的诱导因子DSIF和负性延长因子NELF。磷酸化会使NELF离去,同时会使DSIF转化为正性转录因子,随后RNApol II进入转录延长模式,转录延长过程启动 1
抑制CDK9会导致抗凋亡蛋白Mcl-1、XIAP等的下调,从而使这些抗凋亡蛋白失去维持肿瘤细胞稳定性的能力,进而诱导肿瘤细胞的凋亡。CDK9还参与许多细胞功能的调节。选择性地抑制CDK9还可以作为肿瘤侵袭和转移的潜在治疗策略。最近也有报道CDK9的抑制剂能够通过抑制转录和转录后修饰从而下调MYC蛋白,因此对MYC驱动的肿瘤有抑制的作用 2
此外抑制CDK9能够增加肿瘤环境中CD45 +细胞数,提高CD3 +T细胞的比例和激活树突细胞,因此联合CDK9的抑制剂能够增强肿瘤免疫检验点抑制剂(checkpoint blockage)的免疫响应 3
CDK作为治疗肿瘤和其他一些疾病的重要靶点,近20年来已有许多CDK抑制剂进入临床,并已有选择性CDK4/6抑制剂上市,这为研发选择性CDK抑制剂带来信心和希望。CDK9作为新颖和具有巨大潜力的抗肿瘤药物靶标,受到越来越多的关注,已有多个选择性CDK9抑制剂进入临床(Fadraciclib、Zotitraciclib、KB-130742和AZD-4573等),以CDK9作为抗肿瘤药物靶标具有广阔应用前景。
目前CDK9抑制剂按其母核结构大致分为:黄酮类、嘧啶类、吡啶类、苯三嗪类等其他类。其中一些CDK9抑制剂对CDK9具有较高的选择性(WO2017001354,WO2018192273,WO2019154177等)。
但这些现有技术中公开的化合物以及试验药物在有效性、安全性或选择性等方面依然存在不确定性,因此有必要研究和开发新的选择性的CDK9抑制剂。

本发明中立体化学的定义和惯例的使用通常参考以下文献:
S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-HillBook Company,New York;and Eliel,E.and Wilen,S.,"Stereochemistry of Organic Compounds",John Wiley&Sons,Inc.,New York,1994.本发明的化合物可以包含不对称中心或手性中心,因此存在不同的立体异构体。本发明的化合物所有的立体异构形式,包括但绝不限于,非对映体,对映异构体,阻转异构体,和它们的混合物,如外消旋混合物,组成了本发明的一部分。非对映异构体可以以其物理化学差异为基础,通过层析、结晶、蒸馏或升华等方法被分离为个别非对映异构体。对映异构体可以通过分离,使手性异构混合物转化为非对映异构混合物,其方式是与适当光学活性化合物(例如手性辅助剂,譬如手性醇或Mosher氏酰氯)的反应,分离非对映异构体,且使个别非对映异构体转化为相应的纯对映异构体。本发明的中间体与化合物也可以不同互变异构形式存在,且所有此种形式被包含在本发明的范围内。很多有机化合物都以光学活性形式存在,即它们有能力旋转平面偏振光的平面。在描述光学活性化合物时,前缀D、L或R、S用来表示分子手性中心的绝对构型。前缀d、l或(+)、(-)用来命名化合物平面偏振光旋转的符号,(-)或l是指化合物是左旋的,前缀(+)或d是指化合物是右旋的。这些立体异构体的原子或原子团互相连接次序相同,但是它们的立体结构不一样。特定的立体异构体可以是对映体,异构体的混合物通常称为对映异构体混合物。50:50的对映体混合物被称为外消旋混合物或外消旋体,这可能导致化学反应过程中没有立体选择性或立体定向性。术语“外消旋混合物”和“外消旋体”是指等摩尔的两个对映异构体的混合物,缺乏光学活性。
“互变异构体”或“互变异构的形式”是指不同能量的结构的同分异构体可以通过低能垒互相转化。例如质子互变异构体(即质子移变的互变异构体)包括通过质子迁移的互变,如酮式-烯醇式和亚胺-烯胺的同分异构化作用。原子价(化合价)互变异构体包括重组成键电子的互变。除非其他方面表明,本发明所描述的结构式包括所有的同分异构形式(如对映异构,非对映异构,和几何异构):例如含有不对称中心的R、S构型,双键的(Z)、(E)异构体,和(Z)、(E)的构象异构体。因此,本发明的化合物的单个立体化学异构体或其对映异构体,非对映异构体,或几何异构体的混合物都属于本发明的范围。
“可药用盐”指本发明化合物的盐,这类盐用于人或动物体内时具有安全性和有效性。化合物的盐可以通过在纯的溶液或合适的惰性溶解中用足量的碱或酸获得相应的加成盐。可药用的碱加成盐包括钠、钾、钙、铵、有机氨或镁盐等,可药用的酸加成盐包括无机酸盐和有机酸盐,所述的无机酸和有机酸包括盐酸、氢溴酸、碳酸、碳酸氢根、磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸一氢根、乙酸、马来酸、丙二酸、琥珀酸、饭丁烯二酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸和甲磺酸等(参见Berge et al.,“Pharmaceutical Salts”,Journal of Pharmaceutical Science 66:1-19(1977))。
与现有技术相比,本发明提供的用作CDK9抑制剂的多环酰胺类衍生物具有如下有益效果:
本发明提供了一种新结构的CDK9抑制剂,试验结果表明,该多环酰胺类衍生物表现出优异的CDK9酶抑制活性,同时表现出优异的安全性和选择性,可用于制备治疗癌症,尤其是血液癌,包括急性髓细胞白血病、多发性骨髓瘤、慢性淋巴细胞性白血病、滤泡性淋巴瘤等和实体瘤,包括乳腺癌、前列腺癌、卵巢癌、肝细胞癌、胰腺癌、肾癌、胃癌、结直肠癌和肺癌等疾病的药物。
