Definitions

  • the invention belongs to the field of medicine, in particular, the invention relates to a pyridazinone compound as a PARP7 inhibitor, a preparation method and an application.
  • PARP Poly-ADP-ribose polymerase
  • the PARP protein family consists of 17 members, all of which contain a common catalytic domain of about 230 amino acids, and their catalytic activities belong to 3 different categories, the first category is MonoPARP, most PARP family members catalyze single ADP-ribose The transfer of the unit on its substrate; the second type is PolyPARP, including PARP1, PARP2, TNKS, and TNKS2 that catalyze the transfer of poly ADP-ribose units on the substrate; the third type is PARP13, which is so far the only one that cannot be in vitro Or PARP displaying catalytic activity in vivo. PolyPARPs can sequentially add many ADPR molecules to proteins, resulting in ADPR chains that can be hundreds of units long.
  • MonoPARPs modify proteins by attaching only a single ADPR molecule.
  • PolyPARPs and MonoPARPs represent two distinct classes of therapeutic targets because they have different ADP-ribosylated protein substrates and play different roles in cell signaling and protein function regulation.
  • PARP inhibitors are the first drugs developed and marketed according to the principle of synthetic lethality, and are developed to target DNA repair defects in tumor cells. There are two ways of repairing DNA breaks: single-strand break repair and double-strand break repair. Both repair pathways are intact in normal cells, but homologous recombination repair (HR) defects often occur in tumor cells. PARP enzyme is involved in DNA single-strand break repair and non-homologous recombination terminal linking. When PARP inhibitors are used to prevent the repair of PARP enzyme, due to the defect of homologous recombination repair in tumor cells, DNA errors will continue to accumulate, and eventually Tumor cell apoptosis.
  • the MonoPARP protein family plays a role in multiple stress responses associated with the development of cancer, inflammatory diseases, and neurodegenerative diseases, and its member PARP7 has been shown to be associated with a variety of cancers, including squamous cell carcinoma of the lung (SCCL), non- Small cell lung cancer (NSCLC), etc. High levels of PARP7 are not expressed in normal cells, but PARP7 expression levels rise during cellular stress, such as in cancer cells and virus-infected cells. In these cells, the stability of the genome is reduced and PARP7 modulates cellular activity through negative feedback regulation of the type 1 interferon response. PARP7 has been shown to be highly active in tumors and plays a key role in cancer cell survival.
  • PARP7 for intrinsic cell survival, and that PARP7 can also make cancer cells immune to the body's immune system. Inhibiting PARP7 effectively inhibits cancer cell growth and restores interferon signaling, effectively unleashing the "brakes" that cancer uses to hide from the immune system, inhibiting both innate and adaptive immune mechanisms.
  • PARP7 inhibitors exhibit durable tumor growth inhibition, potent antiproliferative activity, and restoration of interferon signaling.
  • RBN-2397 an oral PARP7 small molecule inhibitor developed by Ribon, is being developed for the treatment of solid tumors.
  • RBN-2397 By inhibiting PARP7 in tumor cells, RBN-2397 has been shown to directly inhibit cell proliferation, as well as restore interferon signaling that can activate innate and adaptive anti-tumor immune responses. RBN-2397 monotherapy is currently in Phase 1 clinical trials for patients with advanced solid tumors.

本发明属于医药领域,具体地,本发明涉及到一种作为PARP7抑制剂的哒嗪酮类化合物及制备方法和用途。
背景技术
多聚ADP核糖聚合酶(poly-ADP-ribose polymerase,PARP)是存在于多数真核细胞中的一个多功能蛋白质翻译后修饰酶。它通过识别结构损伤的DNA片段而被激活,被认为是DNA损伤的感受器。参与包括DNA修复、基因组稳定性等在内的一系列细胞过程。PARP蛋白家族由17个成员组成,它们都包含一个约230个氨基酸的共同催化结构域,而它们的催化活性属于3种不同类别,第1类是MonoPARP,大多数PARP家族成员催化单ADP-核糖单元在其底物上的转移;第2类为PolyPARP,包括PARP1、PARP2、TNKS、TNKS2催化聚ADP-核糖单元在受质上的转移;第3类为PARP13,是迄今为止唯一的不可在体外或体内展示催化活性的PARP。PolyPARPs可以依次将许多ADPR分子添加到蛋白质中,产生的ADPR链可以长达数百个单位。相反,MonoPARPs仅通过连接单个ADPR分子来修饰蛋白。因此,PolyPARPs和MonoPARPs代表了两类不同的治疗靶标,因为它们具有不同的ADP-核糖基化蛋白底物,在细胞信号传导和蛋白功能调节中发挥不同的作用。
PARP抑制剂是第一个按照合成致死的原理研发并且上市的药物,针对肿瘤细胞的DNA修复缺陷进行开发。DNA的断裂修复有单链断裂修复和双链断裂修复两种方式,正常的细胞两种修复路径都是完好的,而肿瘤细胞则常出现同源重组修复(HR)缺陷。PARP酶参与DNA的单链断裂修复和非同源重组末端链接,当使用PARP抑制剂来阻止PARP酶的修复作用时,由于肿瘤细胞本身的同源重组修复缺陷,会导致DNA错误不断积累,最终肿瘤细胞凋亡。目前全球已上市的PARP抑制剂有4个,分别是阿斯利康的奥拉帕利,Clovis的芦卡帕利,Tesaro的尼拉帕利和辉瑞的他拉唑帕利,其中奥拉帕利和尼拉帕利已经在国内上市。从目前的数据看,各种PARP抑制剂的效果并没有明显的区别,PFS和ORR提升明显,但对OS的提高较少。由于大部分肿瘤都或多或少存在HRD,因此PARP抑制剂还有更大的适应症拓展空间,前景广阔。
MonoPARP蛋白家族在与癌症、炎性疾病和神经退行性疾病发展相关的多种应激反应中起 作用,其成员PARP7已被证明与多种癌症相关,包括肺鳞状细胞癌(SCCL)、非小细胞肺癌(NSCLC)等。正常细胞中不表达高水平的PARP7,但在细胞应激状态下,PARP7表达水平上升,例如在癌细胞和病毒感染细胞中。在这些细胞中,基因组的稳定性下降,PARP7通过负反馈调节1型干扰素应答,调节细胞活性。PARP7被证明在肿瘤中高度活跃,且对癌细胞生存起着关键作用。研究发现,许多癌细胞都依赖PARP7来实现内在的细胞存活,PARP7还可以使癌细胞不受人体免疫系统影响。抑制PARP7可有效抑制癌细胞的生长并恢复干扰素信号传导,有效释放癌症用于躲避免疫系统,抑制先天和适应性免疫机制的“刹车”。在几种癌症模型中,PARP7抑制剂表现出持久的肿瘤生长抑制作用、有效的抗增殖活性以及干扰素信号传导恢复作用。RBN-2397是Ribon公司开发的一种口服PARP7小分子抑制剂,正在开发用于治疗实体瘤。通过抑制肿瘤细胞中的PARP7,RBN-2397已被证明可以直接抑制细胞增殖,以及恢复可以激活先天和适应性抗肿瘤免疫反应的干扰素信号。RBN-2397单药治疗晚期实体瘤患者目前正处于1期临床试验阶段。
目前仍然需要开发更多有效的PARP7抑制剂以满足临床需要。
