Definitions

  • the invention belongs to the technical field of medicinal chemistry, and specifically relates to a protein degrading agent, its preparation method and its pharmaceutical application.
  • PARP stands for poly-ADP-ribose polymerase, which is poly-ADP ribose polymerase. It participates in a series of cellular processes including DNA repair, genome stability, etc.; this protein family consists of 18 members, including PARP1, PARP2, etc. .
  • PARP inhibitors bind to the catalytic site of PARP1 or PARP2, causing the PARP protein to be unable to be shed from the DNA damage site.
  • PARP bound to DNA will stall DNA replication during DNA replication, further causing BER to be restricted.
  • cells will trigger homologous recombination repair, and BRCA1, BRCA2 and other proteins called "BRCA-like" play an important role in homologous repeat repair. Therefore, in BRCA-mutated cancer cells, homologous recombination repair cannot proceed.
  • the function of PARP is inhibited, so that cancer cells can only carry out error-prone DNA double-strand repair methods, leading to cancer cell death.
  • PARP inhibitors are currently an effective means of treating cancer and are a hot topic and focus in the research and development of anti-tumor drugs. With the continuous deepening of research on PARP inhibitors, some problems that are not conducive to the application of PARP inhibitors in clinical practice have been discovered and need to be further explored and clarified. The first is the safety issue of long-term use of the drug. Among the four PAPR inhibitors currently on the market, except for Talazoparib, the other three require a daily intake of 300-600 mg of the drug. PARP inhibitors have a short half-life and require frequent administration. Long-term and large amounts of PARP inhibitors during treatment not only have a killing effect on tumor cells, but also have a certain killing effect on normal cells.
  • PARP inhibitors have shown certain tumor tissue selectivity, it remains to be seen whether this selectivity can be maintained under the long-term effects of a large number of drugs. When used in combination, it is also very important to ensure the therapeutic effect while reducing adverse reactions. Therefore, an appropriate dosage range for PARP inhibitors must be determined. The second problem is that the mechanism of drug action is not completely clear. Third, long-term use of PARP can easily lead to the development of tumor drug resistance, thereby reducing the efficacy. How drug resistance occurs and how to overcome and improve drug resistance remain to be solved. The development of resistance to PARP inhibitors is a complex process. It is widely accepted that secondary mutations in the BRCA1/2 gene restore its protein function and become resistant to PARP inhibitors.
  • PRTOAC Proteolysis Targeting Chimera
  • PRTOAC is a bifunctional molecule consisting of three parts, including a ligand that binds to the target protein, a ligand that binds to E3 ubiquitin protein ligase, and a Linker that connects them.
  • E3 ubiquitin protein ligases By recruiting target proteins and E3 ubiquitin protein ligases, the target proteins are polyubiquitinated and then degraded by the intracellular ubiquitin protease system.
  • PROTAC compounds have unique advantages.
  • PROTAC Utilizing PROTAC technology, we have developed many PROTAC compounds that efficiently degrade pathogenic proteins in vivo and in vitro. There are already PROTAC compounds entering clinical research.
  • the present invention uses PROTAC technology to design PARP degradation agents, in order to overcome the shortcomings of small molecule PARP inhibitors and at the same time provide a new method for PARP-dependent targeted tumor treatment.

Description

一种蛋白降解剂及其制备方法和其在药学上的应用 技术领域
本发明属于药物化学技术领域,具体涉及一种蛋白降解剂及其制备方法和其在药学上的应用。
背景技术
PARP全称为poly-ADP-ribose polymerase,即多聚ADP核糖聚合酶,参与了包括DNA修复、基因组稳定性等在内的一系列细胞过程;该蛋白家族由18个成员组成,包括PARP1、PARP2等。PARP抑制剂通过与PARP1或PARP2催化位点的结合,导致PARP蛋白无法从DNA损伤点脱落。被束缚在DNA上的PARP在DNA复制时会使DNA复制停滞,进一步导致BER受制。此时,细胞会激发同源重组修复,BRCA1、BRCA2和其他称为“类BRCA”的蛋白在同源重复修复中起到重要作用。因此在BRCA突变的癌细胞中,同源重组修复则无法进行。再加上PARP的功能受到了抑制,使癌细胞只能进行容易出错的DNA双链修复方式,导致癌细胞死亡。
PARP抑制剂是目前治疗癌症的一种有效手段,是抗肿瘤药物研发的热点和重点。随着PARP抑制剂研究的不断深入,在临床上也发现了一些不利于PARP抑制剂应用的问题有待进一步探讨和厘清。首先是药物长期使用的安全性问题。目前上市的4种PAPR抑制剂中除了Talazoparib外,其余3种每天都需要摄入药物300-600mg。PARP抑制剂半衰期较短,需频繁给药。在治疗过程中长期大量的摄入PARP抑制剂不仅对肿瘤细胞有杀伤作用,对于正常细胞也具有一定的杀伤作用。虽然PARP抑制剂表现出了一定的肿瘤组织选择性,但长期大量药物作用这种选择性还能不能保持有待进一步观察。在联合应用时,保证治疗效果的同时减少不良反应也是一个很重要的方面,因此,必须给PARP抑制剂确定一个合适的给药范围。其次是药物作用机制不完全清楚的问题。第三,PARP长期使用易导致肿瘤耐药性的产生,从而降低了疗效。如何出现耐药以及克服、改善耐药问题有待解决。PARP抑制剂的耐药性产生是一个复杂的过程,其中广泛接受的是BRCA1/2基因二次突变,使其蛋白功能恢复进而对PARP抑制剂耐药。另外,53BP1表达缺失和多药耐药等也使得HR功能部分恢复。癌细胞可能还存在其他耐药机制有待进一步研究,针对不同患者应设置更加精细化的治疗方案延缓和避免耐药性的产生。从PARP抑制剂在临床上的疗效也让我们更加有信心进一步开发PARP抑制剂和新的治疗肿瘤的方案。
通过降解靶点致病蛋白来治疗疾病是目前药物研发领域的一种新模式,其中蛋白降解靶向嵌合体(Proteolysis Targeting Chimera,PROTAC)技术是目前用于肿瘤靶向治疗的一项代表性的技术。PRTOAC是一个双功能的分子,由3部分组成,包括与靶蛋白结合的配体,与E3泛素蛋白连接酶结合的配体,以及连接它们的Linker。通过招募靶蛋白和E3泛素蛋白连接酶是靶蛋白多聚泛素化,进而被细胞内的泛素蛋白酶系统降解。相比于传统的小分子抑制剂,PROTAC化合物有其独特的优势。利用PROTAC技术,我们已经开发了很多在体内外高效降解致病蛋白的PROTAC化合物。目前也已经有PROTAC化合物进入临床研究。本发明利用PROTAC技术设计PARP降解剂,以期在克服小分子PARP抑制剂缺陷的同时,为PARP依赖的肿瘤靶向治疗提供一种新的方法。

Envision读取收集荧光信号值(RFU),取最大RFU值,根据以下公式计算实验板上各孔的化合物降解作用效应值:%Effect=100×(Value-ZPE)/(HPE-ZPE)。其中,%Effect为相应实验孔的化合物降解作用效应值,Value为该实验孔的信号值,ZPE为阴性对照实验孔的信号均值,HPE为阳性对照实验孔的信号均值。阳性对照为1μM SK575。待测化合物的浓度经过反应体系稀释3.162倍后的11个浓度为10μM至0.1nM,使用XLFit拟合化合物百分比降解率和11个点浓度数据至参数非线性逻辑公式计算出化合物的DC50值。
实验结果如表1所示:
表1本发明化合物的PARP1蛋白降解活性
参照该实验方法测试本发明的其他化合物,得出的PARP1蛋白降解活性的DC50(nM)值在0.1~100nM之间;优选小于50nM。
实验结论:
本发明化合物对PARP1蛋白具有良好的降解活性。
