Definitions

  • the invention belongs to the field of medicine synthesis. It specifically relates to a pyrazole-containing derivative, its pharmaceutically acceptable salt, its preparation method and its pharmaceutical composition, and its use as an ATR inhibitor in the preparation of medicines for treating tumors or cancer-related diseases.
  • DNA damage is an important source of genome instability, cell canceration or apoptosis.
  • DNA Damage Repair (DNA Damage Repair, DDR) adjusts cells that need to be repaired from two aspects: on the one hand, it prevents cells from entering mitosis by activating DNA damage checkpoints until the repair is completed; on the other hand, it activates and coordinates various repairs pathway to complete DNA damage repair.
  • PIKK PI3K-related kinase family kinases play a dominant role in DDR: DNA-dependent protein kinase (DNA-PK), ataxia telangiectasia mutated kinase (ATM), and ATM and Rad3-related kinase (ATR).
  • DNA-PK and ATM are mainly activated by DNA double-strand breaks (DSB), while ATR is mainly activated by various single-strand damages and participates in the repair of various DNA damages. important.
  • ATR ATM and Rad3 related (ATM and Rad3 related) kinase.
  • Rad3 is a yeast protein that is similar to the ATM protein.
  • ATR is recruited via its chaperone ATRIP to damaged areas covered with replication protein A (RPA).
  • RPA replication protein A
  • ssDNA single-stranded DNA-binding protein of eukaryotes, and the single-stranded DNA (ssDNA) at the damaged site will recruit the ATR-ATRIP complex after being surrounded by RPA.
  • RPA-ssDNA is an important structure in many DNA repair pathways. In addition to homologous recombination (HR), RPA-ssDNA is also involved in nucleotide excision repair, mismatch repair, base excision repair and replication fork restart.
  • ATR-ATRIP to recognize RPA-ssDNA makes it important in sensing DNA damage and replication stress.
  • Activation of ATR is a complex multistep process including autophosphorylation of ATR, recruitment of Rad17-Rfc2-5 to the junction between ssDNA and dsDNA, and loading of the Rad9-Rad1-Hus1(9-1-1) checkpoint clamp And recruit TopBP1 etc.
  • Activation of ATR leads to phosphorylation of various downstream targets such as CHK1, SMC-1, ATM and p21.
  • CHK1 is the most important molecule, which can regulate molecules such as Cdc25A, RAD51, p53 and DNA-PK, and regulate various cellular processes.
  • CHK1 promotes the proteasomal degradation of CDC25A, which can reduce CDK (cyclin-dependent kinase) activity, inhibit cell cycle progression, and buy time for DNA repair. CHK1 also promotes HR through the phosphorylation of BRCA1, BRCA2 and RAD51, and promotes NHEJ through the phosphorylation of DNA-PK, etc.
  • ATR is an important tumor target.

Description

含吡唑类衍生物、其药学上可接受的盐及其制备方法和应用
本申请要求申请日为2021年12月23日的中国专利申请2021115934786和申请日为2022年8月1日的中国专利申请2022109182743的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属于药物合成领域。具体涉及一种含吡唑类衍生物、其药学上可接受的盐、其制备方法及其药物组合物,以及其作为ATR抑制剂在制备治疗肿瘤或癌症相关疾病的药物中的用途。
背景技术
DNA损伤(DNA damage)是导致基因组不稳定,细胞癌变或凋亡的重要来源。DNA损伤修复(DNA Damage Repair,DDR)从两个方面对需要修复的细胞进行调整:一方面通过激活DNA损伤检查点阻止细胞进入有丝分裂期,直至修复完成;另一方面则激活并协调各种修复途径,完成DNA损伤修复。一般认为,DDR中起主导作用的是三个PI3K相关激酶(PIKK)家族的激酶:DNA依赖性蛋白激酶(DNA-PK)、毛细血管扩张性共济失调症突变激酶(ATM),以及ATM和Rad3相关激酶(ATR)。在3个DDR激酶中,DNA-PK和ATM主要被DNA的双链断裂(DSB)激活,而ATR主要被各种单链损伤激活,参与多种DNA损伤的修复,对于复制细胞的生存能力至关重要。
ATR的全称是ATM和Rad3相关(ATM and Rad3 related)激酶。Rad3是一种酵母蛋白,与ATM蛋白相似。ATR通过其伴侣蛋白ATRIP被募集到覆盖有复制蛋白A(RPA)的损伤区域。RPA是真核生物的单链DNA结合蛋白,损伤处的单链DNA(ssDNA)被RPA包围后会募集ATR-ATRIP复合物。RPA-ssDNA是许多DNA修复途径的重要结构。除了同源重组(Homologous recombination,HR)外,RPA-ssDNA还参与核苷酸切除修复,错配修复,碱基切除修复和复制叉重启。ATR-ATRIP识别RPA-ssDNA的能力使其在感知DNA损伤和复制压力方面非常重要。ATR的激活是一个复杂的多步骤过程,包括ATR的自磷酸化,Rad17-Rfc2-5募集到ssDNA和dsDNA之间的连接处,装载Rad9-Rad1-Hus1(9-1-1)检查点钳以及募集TopBP1等。ATR的激活导致多种下游靶标,如CHK1、SMC-1、ATM和p21等的磷酸化。其中CHK1是最为重要的一个分子,它可以调控Cdc25A、RAD51、p53和DNA-PK等分子,调控多种细胞过程。CHK1促进CDC25A的蛋白酶体降解,可以降低CDK(细胞周期蛋白依赖性激酶)活性,抑制细胞周期进程,为DNA修复争取时间。CHK1还通过BRCA1、BRCA2和RAD51的磷酸化促进HR,通过DNA-PK的磷酸化促进NHEJ等。
在多种肿瘤组织中,例如胃癌、肝癌、结直肠癌、卵巢癌、胰腺癌等,均观察到ATR表达水平升高。并且在卵巢癌、胰腺癌病人中,高水平的ATR往往伴随着较低的存活率。多数肿瘤细胞有着较大的复制压力,ATR对于控制复制压力,维持基因组稳定起着不可缺少的作用。因此ATR是一个重要的肿瘤靶标。
本发明提供一类结构新颖的一系列化合物,其对ATR激酶具有良好的抑制活性,且对ATR/mTOR激酶具有良好的选择性。

实施例和中间体的纯化通过硅胶色谱法、反相硅胶色谱法和/或超临界流体色谱法(SFC)进行。硅胶色谱法一般是以硅胶或预装硅胶柱为载体、石油醚/乙酸乙酯或二氯甲烷/甲醇等体系为洗脱剂;反相硅胶色谱法一般是以C18硅胶柱为载体,使用UV检测器(214nm和254nm)和制备型LCMS进行检测,流动相包括乙腈/水(0.1%甲酸)、乙腈/水(0.1%三氟乙酸)和乙腈/水(0.1%氨水)等体系。超临界流体色谱法(SFC)一般是采用不同类型的柱子作为载体,以CO 2/含0.2%NH 3的甲醇(7M氨甲醇溶液)等体系为流动相。

4.数据处理:
使用内插法计算化合物抑制率:分别计算阳性对照和阴性对照的平均值,使用公式:单孔抑制率=1-(单孔信号值-阳性对照信号平均值)/(阴性对照信号平均值-阳性对照信号平均值)即可计算出化合物孔的抑制率。
使用四参数罗吉斯方程曲线作出化合物抑制曲线:将化合物浓度转化成以10为底的对数,将浓度和抑制率导入XLfit软件中,公式为抑制率=最低响应+(化合物浓度^曲线坡度)*(最高响应-最低响应)/(化合物浓度^曲线坡度+半抑制浓度^曲线坡度)。
