Definitions

  • the present invention relates to the field of medical technology, and in particular to a new class of protein arginase methyltransferase-5 (PRMT5) inhibitors, a pharmaceutical composition containing the same, a preparation method thereof, and use of the same as a PRMT5 inhibitor for treating diseases associated with PRMT5 activity.
  • PRMT5 protein arginase methyltransferase-5
  • Cancer treatment can be broadly divided into two categories: cytotoxic therapy and targeted therapy. Cytotoxic therapy may produce a wide range of toxicity; while targeted therapy has the advantage of selectively targeting tumor cells.
  • PRMT5 protein arginase methyltransferase-5
  • SAM S-adenosylmethionine
  • PRMT5 is overexpressed in various cancers, including glioblastoma, leukemia/lymphoma, prostate cancer, and colorectal cancer, and is associated with poor prognosis.
  • the first generation of PRMT5 inhibitors are mainly SAM competitive or non-competitive inhibitors, which lack selectivity for MTAP-deficient cells. Inhibition of PRMT5 in normal cells leads to dose-limiting toxicities such as thrombocytopenia, anemia, and neutropenia.
  • MTA cellular metabolite methylthioadenosine

蛋白质精氨酸酶甲基转移酶-5抑制剂及其医药用途 技术领域
本发明涉及医药技术领域,具体涉及一类新的蛋白质精氨酸酶甲基转移酶-5(PRMT5)抑制剂,含有其的药物组合物,其制备方法,以及其作为PRMT5抑制剂用于治疗与PRMT5活性相关的疾病的用途。
背景技术
癌症的治疗从广义上可以分为2大类:细胞毒性治疗和靶向治疗。细胞毒性疗法可能产生广泛的毒性;而靶向治疗具有选择性的靶向肿瘤细胞的优势。
PRMT5(蛋白质精氨酸酶甲基转移酶-5)是一种II型精氨酸甲基转移酶,通过催化S-腺苷甲硫氨酸(SAM)的甲基转移对参与转录和信号传导的蛋白质对称二甲基化,实现多种必需细胞功能,包括细胞周期进程的调节、细胞凋亡和DMA损伤反应等。PRMT5在各种癌症中过度表达,包括胶质母细胞瘤、白血病/淋巴瘤、前列腺癌和结肠直肠癌,并且与预后不良有关。利用shRNA进行全基因组遗传扰动筛选的数据揭示了PRMT5活性对MTAP(甲基硫代腺苷磷酸化酶)缺失的癌细胞系的重要性(Kruykov et al,2016;Marjon et al,2016and Markarov et al,2016)。
第一代PRMT5抑制剂主要是SAM竞争性或非竞争性的抑制剂,缺少对MTAP缺失细胞的选择性。对正常细胞PRMT5的抑制,导致了剂量限制性毒性如血小板减少症、贫血和中性粒细胞减少症等。
MTAP缺失导致癌细胞中细胞代谢物甲基硫代腺苷(MTA)的积累。MTA是蛋氨酸补偿途径的中间体,对PRMT5具有弱抑制作用,与SAM竞争并可形成PRMT5/MTA复合体。开发新型抑制剂通过结合并稳定PRMT5/MTA复合物,以增强MTA对PRMT5的抑制作用,实现在抑制MTAP缺失癌细胞中的PRMT5活性的同时保留野生细胞中的PRMT5活性,从而有效提高治疗指数。
目前第二代PRMT5抑制剂所公开专利申请有:WO2021163344A1、WO2022115377 A1、WO2022132914 A1、WO2022169948 A1。
