Definitions
- the disclosure relates to the field of medicine, in particular to a compound with PARP7 inhibitory effect, its use and preparation method.
- PARPs Poly-ADP-ribose polymerases
- PARPs Poly-ADP-ribose polymerases
- the PARP family can be divided into three categories according to their catalytic activity: polyPARPs (4, including PARP1, PARP2, PARP5a, PARP5b) for poly-ADP-ribosylation target proteins, monoPARPs (12, including PARP3 , PARP4, PARP6, PARP7, PARP8, PARP9, PARP10, PARP11, PARP12, PARP14, PARP15, PARP16) and catalytically inactive PARP (1, PARP13).
- DNA damage refers to the permanent change of DNA nucleotide sequence that occurs during DNA replication and leads to changes in genetic characteristics. If DNA damage or abnormal changes in genetic information are not corrected, it can affect the function or survival of cells.
- the repair of DNA damage is a programmed, orderly, multi-stage, precise process involving multiple factors, and PARP is an important protein in the DNA repair process, participating in a series of processes including DNA repair, genome stability maintenance, etc. A series of important cellular processes.
- PARP inhibitors There are several PARP inhibitors available: niraparib and talazoparib target PARP1 and PARP2; olaparib and rucaparib target PARP1, PARP2 and PARP3, and olaparib (First-in-Class) represented by the PARP1/2 inhibitor developed by AstraZeneca It has become a blockbuster drug with significant anti-cancer effects, and its indications can be gradually expanded through combination therapy.
- PARP7 plays an important role in cancer and immune response, and is a potential ideal cancer target.
- PARP7-selective chemical probes Due to the lack of PARP7-selective chemical probes in previous studies, most of them used genetic methods to reveal the function of PARP7, so they could not distinguish between enzymatic activity and the entire protein and their relationship. In addition, the lack of mature high-throughput on-target activity screening test methods also hinders the development of corresponding drugs targeting PARP7. In view of the successive reports of research results related to PARP7 in recent years, PARP7 has become an ideal anticancer target. Therefore, timely research and development of new safe and effective PARP7 inhibitors is of great significance. In addition, as mentioned above, in addition to playing an important role in tumors, PARP7 also plays a key role in diseases such as immunity, inflammation, and viral infection. , virus infection and other diseases have potential application value.

Abstract
涉及一种如式(I)所示的具有PARP7抑制作用的化合物、其药学上可接受的盐、立体异构体、溶剂合物或其前药,及其用途和制备方法。
Description
本公开涉及医药领域,特别涉及一种具有PARP7抑制作用的化合物,其用途及制备方法。
Poly-ADP-ribose polymerases(PARPs)是一个蛋白质家族,在人体内由17个不同成员组成,分别在不同的生物过程中起重要作用,其中包括炎症、病毒感染和肿瘤细胞应激。PARP家族按照催化活性可分为三类:多聚ADP-核糖化靶蛋白的polyPARPs(4个,包括PARP1,PARP2,PARP5a,PARP5b),单ADP-核糖化靶蛋白的monoPARPs(12个,包括PARP3,PARP4,PARP6,PARP7,PARP8,PARP9,PARP10,PARP11,PARP12,PARP14,PARP15,PARP16)和无催化活性的PARP(1个,PARP13)。对PARP的研究大多集中在polyPARPs(PARP1,2,5a,and 5b),特别是PARP1/2在DNA损伤修复中的作用研究最多。DNA损伤是指在DNA复制过程中发生的DNA核苷酸序列永久性改变,并导致遗传特征改变的现象。假如DNA损伤或遗传信息的异常改变不能更正,就会影响细胞的功能或生存。DNA损伤的修复是程序化的,有序的、多阶段、多种因子参与的精准过程,而PARP是DNA修复过程中的重要蛋白,参与了包括DNA修复、基因组稳定性维持等在内的一系列重要细胞过程。PARP抑制剂已有多个成药:niraparib和talazoparib靶向PARP1和PARP2;olaparib和rucaparib靶向PARP1、PARP2和PARP3,而且以AstraZeneca研发的PARP1/2抑制剂为代表的olaparib(First-in-Class)已成为抗癌疗效显著的重磅药,而且适应症可以通过联合用药逐渐拓展。
对单ADP-核糖化靶蛋白的monoPARPs研究相对较少。如上所述,PARP家族中的大部分成员(12个)是monoPARPs,近年来对monoPARPs研究发现PARP7在免疫,癌症中有重要作用。其中,研究提示PARP7是AHR的靶基因之一,PARP7是调节AHR活动的负反馈回路的一部分,而AHR可调节免疫功能、炎症等,并在癌症中发挥作用。可以被癌症相关应激诱导,如烟草中的有害化学物质等。通过对和吸烟存在强相关性的肺癌,食管癌和头颈癌的深入研究发现PARP7所处的基因位点有扩增和高表达。研究发现PARP7在肿瘤细胞中过度活跃,许多癌细胞都依赖PARP7实现细胞存活,且有研究表明PARP7可使癌细胞能够逃避免疫系统免疫攻击。而抑制PARP7可有效抑制癌细胞的生长、恢复干扰素信号传导并逆转免疫抑制。在几种癌症模型中,PARP7抑制剂都表现出持久的肿瘤生长抑制作用以及干扰素信号传导恢复的作用。综上所述,PARP7在癌症以及免疫应答中发挥重要作用,是潜在的理想癌症靶点。由于早前的研究缺乏PARP7选择性的化学探针,因此大多采用基因手段揭示PARP7的功能,所以不能区分酶学活性和整个蛋白及相互关系。另外,早前没有成熟的高通量在靶活性筛选测试手段也阻碍了相应的针对PARP7靶点的药物研发。鉴于近年来PARP7相关研究结果的陆续报道,PARP7成为了比较理想的抗癌靶点。因此,及时地研究开发新的安全有效的PARP7抑制剂具有重要意义。另外,如上所述,除了在肿瘤中发挥重要作用之外,PARP7还在免疫,炎症,病毒感染等疾病也起关键作用,所以,PARP7抑制剂除了有抗癌作用外,还预期在免疫,炎症,病毒感染等其他疾病具有潜在的应用价值。
