  • CCD cell cycle disease
  • CDKs Cyclin-Dependent-Kinases
  • CDKs-centered cell cycle regulatory networks abnormalities in any link will cause cell cycle abnormalities, and ultimately lead to tumors.
  • the CDK family currently has 21 subtypes that function by binding to its regulatory subunit cyclins (cyclins).
  • cyclins regulatory subunit cyclins
  • the function of various subtypes of CDK in addition to acting on the cell cycle, also includes regulation of transcription, DNA repair, differentiation, and programmed cell death.
  • the CDKs kinase family Based on the key role of CDKs in regulating tumor cell proliferation and death, the CDKs kinase family provides opportunities and new fields for the discovery and development of anti-tumor drugs.
  • the first-generation CDK inhibitors represented by flavopiridol, UCN-01, etc. are "pan-CDK” inhibitors, which block all subtypes of the CDK family in an equivalent manner and show up in clinical trials. Higher toxicity and some inability to achieve effective therapeutic doses have spurred the development of selective CDK inhibitors, which are expected to increase the selectivity of treatment and prevent normal cells from being damaged by some side effects.
  • CDK4/6 plays an irreplaceable role in the CDK subtype involved in the cell cycle.
  • the cell cycle mutations associated with cancer are mainly present in the G1 and G1/S phase transformations.
  • the complex formed by CDK4/6 and CyclinD phosphorylates the tumor suppressor gene Rb product pRb, releasing the bound transcription factor E2F, and initiates The transcription of the gene involved in the S phase causes the cells to pass through the checkpoint and transfer from the G1 phase to the S phase.
  • About 80% of human tumors have cyclinD-CDK4/6-INK4-Rb Abnormality of the pathway. The change of this pathway accelerates the G1 phase process, which accelerates the proliferation of tumor cells and gains a survival advantage.
  • CDK4/6 has become a new anti-tumor target.
  • the advantages of CDK4/6 as an anti-tumor target are: (1) Most proliferating cells rely on CDK2 or CDK4/6 proliferation, but CDK4/6 inhibitors do not exhibit cytotoxicity of "pan-CDK inhibitors", such as Myelosuppression and intestinal reactions. (2) Preclinical experiments show that if the level of cyclin D is increased or P16INK4a is inactivated, the sensitivity of the cells to drugs can be increased. Since the tumor cells have the above phenomenon relative to normal cells, the drug targeting is increased to some extent. Sex.

Description

激酶抑制剂及其用途 技术领域
本发明属于医药技术领域。特别地,本发明涉及CDK4/6激酶抑制剂、其药学上可接受的盐、其酯、其溶剂化物或它们的立体异构体,含有所述CDK4/6激酶抑制剂、其药学上可接受的盐、其酯、其溶剂化物或它们的立体异构体的药物制剂、药物组合物和试剂盒,以及所述CDK4/6激酶抑制剂、其药学上可接受的盐、其酯、其溶剂化物或它们的立体异构体的用途。例如,本发明的化合物可用于降低或抑制细胞中的CDK4/6激酶的活性,和/或治疗和/或预防由CDK4/6激酶介导的癌症相关疾病。
背景技术
肿瘤的发生与多种癌基因和抑癌基因的失衡有关。几乎所有癌基因、抑癌基因的功能效应,最终都会汇聚到细胞周期上来。因此,可以说肿瘤是一类细胞周期性疾病(Cell Cycle Disease,CCD),调节或阻断细胞周期是***的途径之一。目前,已发现的与细胞周期调控有关的分子很多,其中细胞周期蛋白依赖性激酶(Cyclin-Dependent-Kinases,CDKs)是细胞周期调控网络的核心分子。CDKs为催化亚单位,是一类丝氨酸(Ser)/苏氨酸(Thr)激酶,作为细胞内重要的信号传导分子,参与细胞周期的不同时期。研究表明,以CDKs为中心的细胞周期调控网络,任何环节的异常都将引起细胞周期异常,最终导致肿瘤的发生。CDK家族目前有21个亚型,通过与其调节性亚单元cyclins(细胞周期蛋白)结合发挥作用。CDK各种亚型的功能,除了作用于细胞周期之外,还包括对转录、DNA修复、分化和细胞程序性死亡的调节。基于CDKs在调控肿瘤细胞的增殖和死亡中所起的关键作用,CDKs激酶家族为抗肿瘤药物的发现与研制提供了机会和新的领域。
在研发药物中,以flavopiridol、UCN-01等为代表的第一代CDK抑制剂为“pan-CDK”抑制剂,它们以等效的方式阻断CDK家族所有亚型,在临床试验中表现出了比较高的毒性,有的不能达到有效的治疗剂量,因此激发人们开始研发选择性CDK抑制剂,期望能提高治疗的选择性以及防止正常细胞受到一些副作用的损害。
在参与细胞周期的CDK亚型中,CDK4/6发挥着不可替代的作用。与癌症有关的细胞周期突变主要存在于G1期和G1/S期转化过程中,CDK4/6与CyclinD形成的复合物,通过抑癌基因Rb产物pRb磷酸化,释放结合的转录因子E2F,启动与S期有关的基因转录,促使细胞通过检验点,并从G1期向S期转移。大约80%的人类肿瘤中有cyclinD-CDK4/6-INK4-Rb 通路的异常。这条通路的改变,加速了G1期进程,使得肿瘤细胞增殖加快而获得生存优势。因此,对该通路的干预成为一种治疗策略,CDK4/6成为一种新的抗肿瘤靶点。CDK4/6作为抗肿瘤靶点的优势在于:(1)大多数增殖的细胞依赖CDK2或者CDK4/6增殖,但CDK4/6的抑制剂不表现出“pan-CDK抑制剂”的细胞毒性,如骨髓抑制和肠道反应。(2)临床前实验表明,如果细胞cyclin D水平升高或者P16INK4a失活,能够增加细胞对药物的敏感性,由于肿瘤细胞相对于正常细胞存在上述现象,所以一定程度上增加了药物的靶向性。
目前为止还没有CDK抑制剂药物上市,包括辉瑞,礼来和诺华等在内的一些医药公司陆续报道一系列选择性较好的CDK4/6抑制剂,正在临床试验阶段。其中,特别值得关注的是Pfizer开发的PD0332991(palbociclib)和Eli Lilly的LY2835219(Phase III)和Novartis的LEE-011(Phase III)。
Figure PCTCN2014095615-appb-000001
2013年4月,辉瑞的PD0332991获得FDA重大突破药物认定,2014年8月,已向FDA提交新药申请(NDA),寻求批准PD0332991(palbociclib)联合曲唑(letrozole)用于既往未接受过***治疗以控制晚期病情的绝经后女性***受体阳性(ER+)、人表皮生长因子受体2阴性(HER2-)局部晚期或转移性乳腺癌的治疗。这对CDK4/6抑制剂的开发起着非常正面的作用。
为了达到更好的肿瘤治疗效果的目的,更好的满足市场需求,我们希望能够开发出新一代的高效低毒的CDK4/6抑制剂。本发明将提供一种新型结构的选择性CDK4/6抑制剂,并发现此类结构的化合物具有很好的药效,且能有效通过血脑屏障,为CDK抑制剂作为脑癌的治疗提供了可能性。
