Definitions

  • the present invention relates to purine derivatives represented by general formula (I), or their stereoisomers, solvates, prodrugs, metabolites, deuterated products, pharmaceutically acceptable salts or co-crystals, their pharmaceutical compositions and Preparation of DNA-PK inhibitors.
  • DNA-dependent protein kinase is a DNA-PK enzyme complex composed of Ku70/Ku80 heterodimer and DNA-dependent protein kinase catalytic subunit (DNA-PKcs). The enzyme complex needs to be activated with the participation of DNA to perform its corresponding functions (George et al., 2019). As a serine/threonine protein kinase, DNA-PK belongs to the PIKK (phosphatidylinositol 3-kinase-related kinase) family.
  • PIKK phosphatidylinositol 3-kinase-related kinase
  • DSBs In the normal physiological process, a variety of factors may lead to the occurrence of DSBs in DNA: For example, DSBs often appear as intermediate products in the process of somatic DNA recombination. This physiological process is very important for the formation of the functional immune system of all vertebrates; DNA replication is in progress. When the replication fork encounters damaged bases, it may also cause single-strand or double-strand breaks; DNA may also generate DSBs due to the attack of reactive oxygen species (ROS) during normal metabolism (Cannan & Pederson, 2016).
  • ROS reactive oxygen species
  • DSBs ionizing radiation (IR) and chemotherapeutic agents (such as topoisomerase II inhibitors)
  • IR ionizing radiation
  • chemotherapeutic agents such as topoisomerase II inhibitors
  • NHEJ non-homologous end-joining
  • NHEJ is a dynamic process mediated by DNA-PK that requires the participation of multiple proteins and signaling pathways.
  • the basic process is as follows: (1) Ku70/Ku80 heterodimer recognizes and binds to the ends of double-stranded DNA breaks; (2) Recruitment DNA-PKcs, XRCC4-DNA ligase IV complex and other proteins to both sides of the DNA break double-strand; (3) DNA-PKcs autophosphorylate and activate its own kinase activity; (4) DNA-PKcs as an adhesive to connect Break both ends of the DNA to prevent exonuclease from degrading the DNA; (5) Process the DNA to remove unlinkable ends or other forms of damage at the break; (6) XRCC4-DNA ligase IV complex repair DNA ends (in some cases, DNA polymerase may be required to synthesize new ends before ligation).
  • DNA-PKcs When DNA-PKcs is phosphorylated, it can induce protein conformation to change and regulate the activity of various proteins in the NHEJ process (such as Artemis, Ku70, Ku80, DNA ligase), which is essential for the DNA repair process. Therefore, phosphorylated DNA-PKcs (pDNA-PKcs) is often used as a marker of cellular DSBs.
  • DNA-PK activity is related to the occurrence and development of a variety of tumors: for example, DNA-PKcs in melanoma can promote angiogenesis and tumor metastasis; DNA-PKcs expression in multiple myeloma is significantly up-regulated; radiotherapy The content of Ku protein in tolerant thyroid tumors is significantly increased (Ihara, Ashizawa, Shichijo, & Kudo, 2019). Therefore, it can be considered to combine DNA-PK inhibitors with anti-tumor therapies that cause DNA damage (such as IR, chemotherapeutic agents, etc.) to improve the effect.
  • the use of DNA-PK inhibitors can interfere with the DNA repair function of normal cells to a certain extent. However, there are many DNA repair pathways in normal cells as a supplement, and tumor cells face strong DNA replication pressure and lack effective DNA repair methods. . By inhibiting the activity of tumor cell DNA-PK, the killing effect of other anti-tumor drugs on tumor cells can be improved.
  • DNA-PK inhibitors After years of research, several DNA-PK inhibitors have been discovered.
  • the first compound found to have DNA-PK kinase inhibitory activity is a fungal metabolite-Wortmannin, with an IC50 (DNA-PK) of about 15nM.
  • DNA-PK IC50
  • This compound also plays an important role in the acetylation and phosphorylation of p53 protein ( Sarkaria et al., 1998); LY294002, a quercetin derivative reported later, also has DNA-PK inhibitory activity (Maira, Stauffer, Schnell, & Garcia-Echeverria, 2009); later based on the structure of LY294002, NU7026 and NU7441 were developed.
  • a generation of DNA-PK inhibitors A generation of DNA-PK inhibitors.
  • DNA-PK inhibitors have also been reported, such as OK1035, SU11752, PP121, KU-0060648 and other small molecule compounds, but these compounds also have defects such as low specificity for DNA-PK (George et al., 2019). Therefore, there is still a need to develop DNA-PK inhibitors with high activity, high specificity, and low toxicity to better meet clinical needs.

Description

嘌呤衍生物及其在医药上的用途 技术领域
本发明涉及通式(I)所示的嘌呤衍生物,或者其立体异构体、溶剂化物、前药、代谢产物、氘代物、药学上可接受的盐或共晶,其药物组合物以及在制备DNA-PK抑制剂的用途。
背景技术
DNA依赖的蛋白激酶(DNA-dependent protein kinase,DNA-PK)是由Ku70/Ku80异二聚体和DNA依赖的蛋白激酶催化亚基(DNA-PKcs)构成的DNA-PK酶复合物。该酶复合物需要在DNA参与下才能被激活发挥出相应的功能(George et al.,2019)。作为一种丝氨酸/苏氨酸蛋白激酶,DNA-PK属于PIKK(phosphatidylinositol 3-kinase-related kinase)家族成员,它不仅在修复细胞内DNA双链断裂(double-strand breaks;DSBs)和细胞DNA重组或抗体DNA重排(V(D)J重组)过程中具有重要作用,还参与染色体修饰、转录调节、端粒维持等生理过程。
在正常生理过程中,多种因素可能导致DNA发生DSBs:如体细胞DNA重组过程中DSBs常常作为中间产物出现,这一生理过程对所有脊椎动物的功能性免疫系统的形成十分重要;DNA复制中复制叉遇到受损的碱基,也可能造成单链或双链断裂;DNA也可能因为正常代谢过程中活性氧(reactive oxygen species;ROS)的攻击而产生DSBs(Cannan&Pederson,2016)。此外,还有多种外源性因素也可能导致DSBs,如电离辐射(Ionizing radiation,IR)和化疗试剂(如拓扑异构酶II抑制剂)等(George et al.,2019)。如果DSBs未被修复或者错误地修复,将会产生突变和/或染色体畸变,最终导致细胞死亡。为了应对DSBs带来的危害,真核细胞已进化出多种机制来修复受损的DNA以维持细胞的活力和基因组的稳定性。在真核细胞中,最主要的DNA修复方式是非同源末端连接(non-homologous end-joining,NHEJ)。这种直接将断裂DNA连接起来的方式并不需要有同源DNA片段参与,可以发生在细胞周期的任何阶段。NHEJ是由DNA-PK介导的需要多种蛋白与信号通路共同参与的动态过程,基本过程如下:(1)Ku70/Ku80异二聚体识别并结合至双链DNA断裂末端;(2)募集DNA-PKcs、XRCC4-DNA连接酶IV复合体等蛋白至DNA断裂双链的两侧;(3)DNA-PKcs自身磷酸化,激活自身的激酶活性;(4)DNA-PKcs作为粘合剂连接断裂DNA的两端,防止核酸外切酶对DNA的降解作用;(5)对DNA进行加工以移除断裂处的不可连接末端或其他损伤形式;(6)XRCC4-DNA连接酶IV复合体修复DNA末端(某些情况下,在连接之前可能还需要DNA聚合酶来合成新的末端)。当DNA-PKcs发生磷酸化后,可诱导蛋白构象发生改变,调节NHEJ过程中多种蛋白的活性(如Artemis、Ku70、Ku80、DNA ligase),这对DNA修复过程至关重要。因此,磷酸化的DNA-PKcs(pDNA-PKcs)常常作为细胞DSBs的标志物。
已有研究表明,DNA-PK活性与多种肿瘤的发生发展有关:如黑色素瘤中的DNA-PKcs可以促进血管再生和肿瘤的转移;多发性骨髓瘤中的DNA-PKcs表达量显著上调;放疗耐受的甲状腺肿瘤中的Ku蛋白的含量明显增加(Ihara,Ashizawa,Shichijo,&Kudo,2019)。因此,可以考虑将DNA-PK抑制剂与引起DNA损伤的抗肿瘤疗法(如IR、化疗试剂等)联用来提高效果。DNA-PK抑制剂的使用在一定程度上会干扰正常细胞的DNA修复功能,然而正常细胞体内还存在多种DNA修复途径作为补充,而肿瘤细胞面临强大的DNA复制压力且缺乏有效的DNA修复方式。通过抑制肿瘤细胞DNA-PK的活性能够提高其他抗肿瘤药物对肿瘤细胞的杀伤效果。
经多年研究,目前已经发现了多个DNA-PK抑制剂。最早发现具有DNA-PK激酶抑制活性的化合物是一种真菌代谢产物——Wortmannin,IC50(DNA-PK)约15nM,该 化合物同时在p53蛋白的乙酰化和磷酸化过程中也发挥着重要作用(Sarkaria et al.,1998);之后报道的槲皮素衍生物LY294002也具有DNA-PK抑制活性(Maira,Stauffer,Schnell,&Garcia-Echeverria,2009);后来基于LY294002结构又研发了NU7026、NU7441等新一代DNA-PK抑制剂。虽然已经证实了这些化合物对肿瘤细胞有着良好的杀伤效果,但它们存在高毒性、选择性差等问题而无法进入临床开发(Maira et al.,2009)。还曾报道过其他DNA-PK抑制剂,如OK1035、SU11752、PP121、KU-0060648等小分子化合物,但这些化合物同样存在对DNA-PK特异性较低等缺陷(George et al.,2019)。所以,目前仍然需要开发高活性、高特异性、低毒性的DNA-PK抑制剂,以更好满足临床需求。

1、DNA-PK激酶抑制试验
通过DNA-PK激酶检测试剂盒(DNA-PK kinase assay kit)(购买自Promega公司,货号:V4107,批号:0000366495)检测化合物对DNA-PK激酶的抑制活性。利用化学发光对结果进行定量,具体实验方案如下:
i.按照试剂盒说明书构建不同浓度ADP-荧光标准曲线;
ii.于384孔白色板中制备5μL反应体系,每孔中分别加入1μL化合物(分别设定浓度梯度1μM、200nM、40nM、8nM、1.6nM、0.32nM、0.064nM、0.013nM)、20units DNA-PK激酶、0.2μg/μL底物、10μg/μL DNA、50μM ATP、1%DMSO;
iii.混匀,离心(1000rpm,30s),37℃孵育60min;
iv.加入5μL ADP‐Glo TM Reagent终止反应,混匀,离心(1000rpm,30s),室温孵育40min;
v.加入10μL Kinase Detection Reagent,震荡混匀,离心(1000rpm,30s),室温孵育30min;
vi.利用酶标仪(Thermo fisher,Varioskan LUX)测定荧光值。利用GraphPad Prism 8进行IC 50的计算,结果见表1。

2、移植瘤抑制实验
2.1实验材料:A549细胞(购自ATCC);Doxorubicin(多柔比星)脂质体(Dox)(Lipo Doxorubicin,商品名“里葆多”,购自上海复旦张江生物医药股份有限公司);化合物1、6、19、22、34;6周龄雌性裸鼠(体重18-20g)(北京维通利华实验动物技术有限公司),每组10只鼠。
2.2 Doxorubicin与待筛选化合物联用对A549移植瘤的抑制效果测定:
2.2.1收集处于生长对数期的A549细胞,预冷PBS洗2次后备用;
2.2.2 Balb/c裸小鼠实验室环境适应3天,于右肋部皮下接种A549细胞,接种细胞量为5×10 6/只,待肿瘤生长至200mm 3左右时进行药效实验;
2.2.3将成功长瘤的小鼠进行随机分组,设置单独Doxorubicin(Dox)组、待测化合物和Dox联用组、对照组(载体(Vehicle)),给药21天;小鼠灌胃给药(i.g.),每日2次(BID,给药体积5mL/kg;溶剂为5%DMSO+30%2-羟丙基-β-环糊精)。早上灌胃给药1h后,由尾静脉注射Lipo Doxorubicin(2.5mg/kg);每周1次(QW,给药体积5mL/kg;)具体给药方案如下:
Figure PCTCN2020141862-appb-000064
2.2.4每周称量2次小鼠体重,并同时测定肿瘤体积:肿瘤体积(V)计算公式为:V=1/2×L ×L 2,并计算抑瘤率,抑瘤率(%)=(D21肿瘤体积(载体)-D21肿瘤体积(给药组))/D21肿瘤体积(载体)×100;
2.2.5给药21天后,分离肿瘤并称重,并计算体重变化率,体重变化率(%)=(D21体重-D0体重)/D0体重×100。
Figure PCTCN2020141862-appb-000065
结论:实验结果表明,本发明化合物与Doxorubicin联用均显著提高Doxorubicin的肿瘤抑制效果,且不会引起明显的体重减轻。
