Definitions

  • the present invention relates to the field of pharmaceutical compounds. Specifically, the present invention provides a class of compounds for inhibiting PRMT5 and their use in pharmaceutical compositions.
  • Epigenetic regulation of gene expression is an important biological determinant of protein production and cell differentiation and plays an important pathogenic role in many human diseases.
  • Epigenetic regulation involves the heritable modification of genetic material without changing its nucleotide sequence.
  • epigenetic regulation is mediated by selective and reversible modifications (e.g., methylation) of DNA and proteins (e.g., histones) that control conformational transitions between transcriptionally active and inactive states of chromatin.
  • methyltransferases e.g., PRMT5
  • PRMT5 plays a role in diseases such as proliferative, metabolic and hematological diseases.
  • PRMT5 is a known cellular essential gene, and conditional PRMT5 knockout and siRNA knockdown studies have shown that PRMT5 inhibition in normal tissues is associated with a range of diseases (e.g., pancytopenia, infertility, skeletal muscle loss, cardiac hypertrophy). Therefore, new strategies are needed to exploit this metabolic vulnerability and preferentially target PRMT5 in MTAP-null tumors while sparing PRMT5 in normal tissues (MTAPWT).
  • Targeting PRMT5 with MTA synergistic small molecule inhibitors can preferentially target the MTA-bound state of PRMT5, enriched in MTAP-null tumor cells, while providing a therapeutic index superior to normal cells with intact MTAP and low MTA levels.

Description

一类PRMT5抑制剂及其用途 技术领域
本发明涉及药物化合物领域,具体地,本发明提供了一类用于抑制PRMT5的化合物,及其用于药物组合物的用途。
背景技术
基因表达的表观遗传调控是蛋白质产生和细胞分化的重要生物学决定因素,在许多人类疾病中起着重要的致病作用。
表观遗传调控涉及遗传物质的可遗传修饰而不改变其核苷酸序列。通常,表观遗传调控由DNA和蛋白质(例如组蛋白)的选择性和可逆修饰(例如甲基化)介导,这些修饰控制染色质转录活性和非活性状态之间的构象转变。这些共价修饰可以由甲基转移酶(例如PRMT5)等酶控制,其中许多与可能导致人类疾病的特定遗传改变有关。PRMT5在增殖性疾病、代谢性疾病和血液疾病等疾病中发挥作用。
PRMT5是一种已知的细胞必需基因,条件性PRMT5敲除和siRNA敲除研究表明,正常组织中的PRMT5抑制与一系列疾病相关(例如,全血细胞减少症、不孕症、骨骼肌丧失、心脏肥大)。因此,需要新的策略来利用这种代谢脆弱性并优先针对MTAP无效肿瘤中的PRMT5,同时在正常组织中保留PRMT5(MTAPWT)。用MTA协同小分子抑制剂靶向PRMT5可以优先靶向PRMT5的MTA结合状态,富含MTAP无效肿瘤细胞,同时提供优于MTAP完整且MTA水平低的正常细胞的治疗指数。
因此,本领域需要提供新的靶向MTAP无效肿瘤中的PRMT5的小分子化合物。
