Definitions

  • the present invention belongs to the field of medical technology, and specifically relates to a class of polycyclic poly (ADP ribose) polymerase selective inhibitor compounds, pharmaceutically acceptable salts or stereoisomers thereof, pharmaceutical compositions and preparations containing the compounds, pharmaceutically acceptable salts or stereoisomers thereof, methods for preparing the compounds, pharmaceutically acceptable salts or stereoisomers thereof, and uses of the compounds, pharmaceutically acceptable salts or stereoisomers thereof.

  • PARP1 poly(ADP-ribose)polymerase 1
  • PARP1 is the most typical member of the PARP family and plays more than 90% of the functions in the PARP family.
  • PARP1 is a ribozyme that regulates a variety of cellular processes through PARylation (i.e., Poly(ADP-ribosyl)ation, poly ADP-ribosylation modification), including DNA damage signals, chromatin remodeling, transcription, stable replication forks, sensing unconnected Okazaki fragments during replication, inflammation, and metabolism.
  • PARP1 is composed of 1014 amino acid residues, including three domains, the N-terminal DNA binding domain (DBD), the intermediate self-regulatory domain (AD), and the C-terminal catalytic domain (CAT).
  • the N-terminal DNA binding domain includes three zinc finger motifs (ZnI, ZnII, ZnIII) and a DNA strand break sensitive element (NLS). ZnI and ZnII recognize damaged DNA, and ZnIII participates in the connection between domains and activates proteins.
  • the intermediate self-regulatory domain includes a BRCA1 (Breast Cancer 1, breast cancer gene 1) carboxyl terminus (DNA repair and cell signal transduction) and has Capase-3 enzyme cleavage function.
  • the C-terminal catalytic domain includes a tryptophan-glycine-arginine-rich domain (WGR), an ⁇ -helical domain (HD) and an ADP ribosyltransferase domain (ART).
  • WGR tryptophan-glycine-arginine-rich domain
  • HD ⁇ -helical domain
  • ART ADP ribosyltransferase domain
  • PARP1 is essential for timely and accurate repair of single-strand DNA damage. When DNA is damaged, PARP1 is rapidly recruited to single-strand breaks (SSBs), and through binding to single-stranded DNA (ssDNA), it achieves self-polymerization with other proteins and completes the recruitment of downstream DNA repair factors.
  • SSBs single-strand breaks
  • ssDNA single-stranded DNA
  • Homologous recombination repair is one of the core repair methods for double-strand DNA damage.
  • BRCA1 and BRCA2 Breast Cancer 2
  • BRCA1 and BRCA2 Breast Cancer 2
  • BRCA1 initiates HR by promoting the end resection of DSBs (Double-strand breaks), and then works with BRCA2 and PALB2 (Partner and Localizer of BRCA2) to stimulate RAD51 to aggregate to the resected single-stranded DNA, and then use sister chromatids as templates to accurately repair DNA damage.
  • BRCA1 and BRCA2 are also important in the S phase, protecting stalled replication forks from degradation by nucleases.
  • the molecular mechanism of action of PARP inhibitors includes two aspects.
  • PARP1 inhibitors inhibit the catalytic activity of PARP-1 by competitively binding to the CAT (catalytic domain, C-terminal catalytic domain), so that SSB cannot be repaired in time and DSB is generated;
  • PARP-1 inhibitors inhibit the self-PARylation of PARP1, bind to CAT, cause PARP1 conformational change, enhance the binding strength of PARP1 with damaged DNA, and "capture" PARP1. It binds to damaged DNA, making it difficult for other PARP1 in the cell nucleus to bind to damaged DNA, further blocking possible repair pathways of DSB and promoting cell apoptosis.
  • the technical problem to be solved by the present invention is to provide a polycyclic compound with novel structure and good selective inhibitory effect on PARP1. Furthermore, the compound can be used to prevent and/or treat PARP-related diseases.

Description

多环类聚(ADP核糖)聚合酶选择性抑制剂 技术领域
本发明属于医药技术领域,具体涉及一类多环聚(ADP核糖)聚合酶选择性抑制剂化合物、其药学上可接受的盐或其立体异构体,含有所述化合物、其药学上可接受的盐或其立体异构体的药物组合物及制剂,制备所述化合物、其药学上可接受的盐或其立体异构体的方法,以及所述化合物、其药学上可接受的盐或其立体异构体的用途。
背景技术
抑制PARP1(poly(ADP-ribose)polymerase 1,多聚(ADP核糖)聚合酶1)的靶向治疗是现阶段国内外研究的热点之一。PARP1是最典型的PARP家族成员,在PARP家族中发挥90%以上的功能。PARP1是一种核酶,通过PARylation(即Poly(ADP-ribosyl)ation,多聚ADP-核糖基化修饰)调节多种细胞过程,包括DNA损伤信号、染色质重构、转录、稳定复制叉、感应复制过程中未连接的冈崎(Okazaki)片段、炎症和代谢等。PARP1由1014个氨基酸残基组成,包括3个结构域,N端DNA结合域(DBD)、中间自调节域(AD)、C端催化域(CAT)。其中N端DNA结合域包括3个锌指基序(ZnⅠ、ZnⅡ、ZnⅢ)和DNA链断裂敏感元件(NLS)。ZnⅠ、ZnⅡ识别损伤DNA,ZnⅢ参与结构域之间的联系,活化蛋白。中间自调节域包括一个BRCA1(Breast Cancer 1,乳腺癌1号基因)的羧基端(DNA修复和细胞信号转导)并有Capase-3酶切功能。C端催化域包括一个富含色氨酸-甘氨酸-精氨酸域(WGR)、α螺旋结构域(HD)以及ADP核糖转移酶结构域(ART)。PARP1对于及时准确修复DNA单链损伤至关重要,DNA损伤时PARP1迅速招募至单链断裂(SSBs)处,通过与单链DNA(ssDNA)结合实现自身和其他蛋白聚合,完成招募下游DNA修复因子。
DNA同源重组修复(Homologous Recombination Repair,HRR)是DNA双链损伤的核心修复方式之一。BRCA1和BRCA2(Breast Cancer 2,乳腺癌2号基因)被招募后,对同源重组修复进行调节,BRCA1通过促进DSBs(Double-strand breaks,双链断裂)末端切除启动HR,然后与BRCA2和PALB2(Partner and Localizer of BRCA2,BRCA2伴侣及定位蛋白基因)共同作用于下游,刺激RAD51聚集至切除的单链DNA处,之后使用姐妹染色单体作为模板精确修复DNA损伤。除了在HR中的作用,BRCA1和BRCA2在S期也很重要,可以保护停止的复制叉不被核酸酶降解。鉴于BRCA1和BRCA2的上述作用,突变都会增加乳腺癌、卵巢癌、前列腺癌和胰腺癌的发生,源于剩余野生等位基因的丢失以及HR缺陷导致的高水平基因组不稳定性。HR缺陷的BRCA1/2突变肿瘤依赖代偿性DNA修复途径,药物抑制这些途径的关键成分(如PARP1)可致DNA损伤,在缺少BRCA1/2情况下引发关键基因组不稳定、有丝分裂灾难和细胞死亡,最终BRCA1/2和PARP导致协同致死。
PARP抑制剂分子作用机理包括2个方面。一方面,PARP1抑制剂通过与PARP-1的CAT(catalytic domain,C端催化域)竞争性结合,抑制其催化活性,使SSB得不到及时修复,产生DSB;另一方面,PARP-1抑制剂通过抑制PARP1的自身PARylation,与CAT结合导致PARP1变构,增强PARP1与损伤DNA的结合强度,将PARP1“捕获” 于损伤DNA上,使细胞核中其他PARP1难以与损伤DNA结合,进一步阻断DSB的可能修复途径,促进细胞凋亡。
自2014年奥拉帕利被批准用于BRCA突变卵巢癌以来,多款PARP抑制剂已经被开发上市,并取得了广泛的成功。然而药物的不良反应限制了它们与化疗药物联合使用的能力。大多数第一代PARP抑制剂是在PARP1-DNA捕获的概念被发现之前开发和优化的,这是PARP抑制剂对BRCAm细胞施加合成致死效应的机制。此外,由于第一代PARP抑制剂没有在PARP家族中进行选择性优化,这可能导致不良副作用,包括端锚聚合酶(tankyrase)抑制引起的肠道毒性或PARP2抑制导致的血液毒性。因此,开发具有捕获能力,对PARP1具有高选择性的抑制剂,以期在保证药效的同时降低现有PARP抑制剂的毒性,成为PARP抑制剂研究的新方向。
