Definitions

  • the present invention relates to the field of medicinal chemistry; specifically, the present invention relates to novel pyrrolopyrimidine derivatives, their synthesis methods and their application as RSK inhibitors in the preparation of drugs for tumor-related diseases.
  • the Ras-MAPK signaling pathway is involved in regulating many types of cancers.
  • RSK is its most downstream effector, and its abnormal expression and activity are related to the occurrence and development of many diseases.
  • the Ras-MAPK signaling pathway is activated under the stimulation of growth factors, mitogen hormones and neurotransmitters.
  • Cell surface receptor activation leads to enhanced Tyr kinase autophosphorylation and generates docking sites for growth factor receptor binding protein-2 (GRB2), which connects the receptor to serum-free guanine nucleotide exchange factor (SOS).
  • SOS catalyzes GTP binding to Ras.
  • GTP binds to Ras and activates its effector Raf kinase. Raf phosphorylates and activates MAPK and extracellular signal-regulated kinase (MEK1/2).
  • Ribosomal S6 kinase is directly phosphorylated and activated by ERK1/2 and 3-phosphoinositide-dependent kinase-1 (PDK1). Activated RSK is still membrane-associated, free in the cytoplasm, or transported into the nucleus, mediating cell differentiation, proliferation, survival and transformation of proto-oncogenes.
  • the Ras signal transduction pathway can promote cell proliferation and protect cells from apoptosis, and is of great significance to the occurrence and development of human tumors and the maintenance of biological behaviors.

Description

作为RSK抑制剂的吡咯并嘧啶衍生物及其应用 技术领域
本发明涉及药物化学领域;具体地说,本发明涉及新型的吡咯并嘧啶衍生物,其合成方法及其作为RSK抑制剂在制备肿瘤相关疾病的药物中的应用。
背景技术
Ras-MAPK信号通路参与调节多种癌症类型,RSK作为其最下游的效应因子,它的异常表达和活性与多种疾病的发生和发展有关。Ras-MAPK信号通路在生长因子、有丝分裂原激素和神经递质刺激下被激活。细胞表面受体激活导致Tyr激酶自身磷酸化增强,并产生生长因子受体结合蛋白-2(GRB2)的对接位点,其将受体连接到无血清的鸟嘌呤核苷酸交换因子(SOS)。SOS催化GTP结合到Ras。GTP结合Ras并激活其效应物Raf激酶。Raf磷酸化并激活MAPK和细胞外信号调节激酶(MEK1/2)。
核糖体S6激酶(RSK)直接由ERK1/2和3-磷酸肌醇依赖性激酶-1(PDK1)磷酸化并激活。活化的RSK仍然是膜相关的,游离于细胞质中,或转运到细胞核中,介导细胞的分化、增殖、存活及原癌基因的转化等。Ras信号转导通路具有促进细胞增殖和保护细胞免受凋亡的作用,对人类肿瘤的发生、发展及生物学行为的维持具有重要的意义。
p90核糖体S6蛋白激酶(ribosomal S6 kinase,RSK)是在组织中广泛表达的丝氨酸/苏氨酸激酶家族成员,作为Ras信号转导通路下游的重要调控因子,在肿瘤的发生和发展中起重要作用。在哺乳动物中,其有四个亚型,RSK1、RSK2、RSK3和RSK4。四个亚型均有两个功能不同的激酶结构域:N端激酶结构域(N-terminal kinase domain,NTKD)和C端激酶结构域(C-terminal kinase domain,CTKD)以及一个连接区(linker)。在C末端尾部包含特异性的细胞外信号调节激酶(Extracellular signal regulated kinase,ERK)结合部位,该部位与ERK结合后使RSK进一步处于ERK的调控之下。
目前临床上还没有靶向RSK的药物,在研的RSK小分子抑制剂主要包括两类,一类是RSK2选择性抑制剂包括SL0101、CMK等,另一类是RSK的泛抑制剂包括BI-D1870、FMK、LJH308、LJH685等,这些小分子抑制剂均未进入临床研究。
因此,研究开发靶向RSK的药物具有重大的临床意义和应用前景。
