  • the present invention relates to the field of pharmaceutical preparation technology, and in particular to a heteropyridine pyrimidinone derivative as a CDK inhibitor and use thereof.
  • CDK Cyclin-dependent kinase
  • cyclin is important factors in cell cycle regulation.
  • CDK can form a heterodimer with cyclin, in which CD K is a catalytic subunit, cyclin is a regulatory subunit, forms various cyclin-CDK complexes, phosphorylates different substrates, and promotes different cell cycle phases. And transformation.
  • CDK kinases that bind to G1 phase cyclins mainly include CDK2, CDK4 and CKD6.
  • Cyclin D mainly binds to CDK4 and CKD6 and regulates the latter activity;
  • cyclin E binds to CDK2 in G1/S phase, and exhibits CDK 2 kinase activity to promote cell entry into S phase.
  • the G2/M phase is mainly regulated by CDK1 kinase.
  • Cyclin A and CyclinB bind to CDK1.
  • CDK1 phosphorylates the substrate protein.
  • M-phase triggering factor activates the late-promoting factor APC, which is ubiquitously linked to Cyclin.
  • CDK inhibitors have emerged as a new anti-tumor drug in the global pharmaceutical industry, with more than 20 CDK inhibitors entering clinical outbreaks. Although the preclinical pharmacodynamics of anti-tumor effects of CDK inhibitors are significant, most of the previous clinical trial results were unsatisfactory. The main problems include the lack of efficacy and toxicity in solid tumors. (Guha M. Nat Rev Drug Disl 1:892, 2012). However, in the analysis of severe toxic side effects, some CDK inhibitor drugs lacked selectivity for CDK subtypes, and thus produced large side effects.
  • CDK4 and CDK6 are two closely related kinases that bind to Cyclin D during the tumor cell cycle. Bringing the G1 phase into the S phase is essential for the cell cycle progression of DNA replication cell division. In more than 90% of human tumors, changes in the G1-S phase transition control mechanism were observed through various genetic and biochemical adaptations.
  • P16 and human retinoblastoma inhibitory protein are important swelling and pain inhibitory proteins that regulate the cell cycle. The P16 gene protein inhibits the feedback loop of CDK4, Cyclin Dl and Rb, and prevents the excessive proliferation of cells by regulating the protein activity of Rb to achieve tumor suppression.
  • CDK4 and CDK6 have been shown that in human tumors (such as breast and myeloma), activation of CDK4 and CDK6 leads to cell cycle changes. Inhibition of CDK4 and CDK6 prevents the inactivation of the tumor suppressor protein Rb and interferes with tumor cell cycle progression (Choi YJ and Anders L, Oncogene 33: 1890-903, 2014).

Description

说明书 发明名称:杂代吡啶并嘧啶酮衍生物作为 CDK抑制剂及其应用 技术领域
[0001] 本发明涉及药物制备技术领域, 特别是涉及一种杂代吡啶并嘧啶酮衍生物作为 CDK抑制剂及其应用。
背景技术
[0002] 周期蛋白依赖性蛋白激酶 (cyclin-dependent kinase, CDK) 和周期蛋白 (cyclin ) 是细胞周期调控中的重要因子。 CDK可以和 cyclin结合形成异二聚体, 其中 CD K为催化亚基, cyclin为调节亚基, 形成各种 cyclin-CDK复合物, 使不同底物磷 酸化, 对细胞周期不同的吋相起推进和转化作用。
[0003] 在哺乳动物中至少存在 9种 CDK。 细胞由 G1期向 S期转化主要受 G1期 CDK激酶 控制。 与 G1期细胞周期蛋白 (cyclin) 结合的 CDK激酶主要包括 CDK2、 CDK4 和 CKD6。 Cyclin D主要与 CDK4和 CKD6结合并调节后者活性; cyclin E在 G1/S期 与 CDK2结合, 呈现 CDK 2的激酶活性促进细胞进入 S期。 G2/M期主要受 CDK1 激酶调控, Cyclin A、 CyclinB与 CDK1结合, CDK1使底物蛋白磷酸化, 如将组 蛋白 HI磷酸化则导致染色体凝缩, 如将核纤层蛋白磷酸化则使核膜解体。 在 M 期, M期促发因子 (MPF) 激活后期促进因子 APC, 将泛连接在 Cyclin
A和 Cyclin B上, 通过多泛素化作用, 使它们被蛋白酶体降解, 完成一个细胞周 期 (Malumbres M.etal.Nat Cell Biol 11: 1275,2009;Malumbres M.etal.Nat Rev Cancer 9: 153,2009)。
[0004] 过去十年来, CDK抑制剂作为抗肿瘤新药幵发为全球药业的一个热点, 有超过 20个 CDK抑制剂进入临床幵发。 尽管 CDK抑制剂抗肿瘤临床前药效学结果显著 , 但是早前多数临床试验结果不尽人意。 主要问题包括在实体瘤缺乏疗效和毒 性较大。 (Guha M . Nat Rev Drug Disl 1:892,2012) 。 而在分析产生严重毒副作 用吋发现, 部分 CDK抑制剂药物对 CDK亚型缺乏选择性, 因此产生了较大的毒 副作用。
[0005] CDK4和 CDK6是两个密切相关的激酶, 在肿瘤细胞周期中与 Cyclin D结合促 使 Gl期进入 S期, 是 DNA复制细胞分裂的细胞周期进程必需的。 而超过 90%的人 类肿瘤中, 均发现通过各种的基因和生化适应导致 G1-S期的过渡控制机制改变 。 P16和人视网膜母细胞瘤抑制蛋白 (retinoblastom^Rb) 是重要的肿痛抑制蛋白 , 其能调控细胞周期。 P16基因蛋白抑制 CDK4、 Cyclin Dl和 Rb的反馈回路, 并 通过调节 Rb的蛋白活性, 从而防止细胞过度增殖, 以达到抑制肿瘤的目的。 已 经证明在人体肿瘤中 (如乳腺癌和骨髓瘤) , CDK4和 CDK6激活导致细胞周期 改变发生。 而抑制 CDK4和 CDK6, 可阻止肿瘤抑制蛋白 Rb的失活和干扰肿瘤细 胞周期进展 (Choi YJ and Anders L , Oncogene 33: 1890-903,2014) 。
[0006] 由于 CDK4/6在各种实体肿瘤和血液肿瘤的细胞周期控制失调中起关键作用 。 目前, 选择性 CDK4/6抑制剂目前有多个处于临床阶段 (如 PalbOCiclib、 LY283 5219和 LEE011) 。 这些药物的临床评价还包括转移性乳腺癌、 卵巢癌、 脂肪肉 瘤、 非小细胞肺癌、 肝癌、 胶质母细胞瘤、 黑素瘤、 多发性骨髓瘤和淋巴瘤等
[0007] 虽然有许多 CDK抑制剂类化合物已经被公幵, 但是, 由于受 CDK介导的病理 的原因, 仍然需要大量用于治疗与 CDK有关的障碍的大量药物, 特别是 CDK4/6 抑制类药物。

Screen,2009,PP31) 。 将待测化 合物以 DMSO溶解后用激酶缓冲溶液 (20mM HEPES-pH 7.5, 0.01% Triton X-100, 10mM MgCl 2, 2mM DTT)稀释, 在 384孔板中加入 5 L的 10<¾DMSO溶解 的 5倍反应终浓度的化合物, 无化合物对照孔是 5μί的 10%DMSO, 无没活性对照 孔是 5μί的激酶缓冲液。 加入 ΙΟμί稀释 2.5倍后的 CDK6酶溶液 (GST-CDK6(l-32 6end)) 后在室温下孵育 10min, 再加入 ΙΟμί的稀释 2.5倍后的底物溶液 Peptide FAM-P8。 28。C下孵育 40min后加 25μί终止液终止反应, Caliper EZ Reader II
(Caliper Life Sciences) 上读取转化率数据, 按照上述方法把转化率转化成抑制 率数据。 其中, 抑制率 <¾= (max-转化) I (max-min) χ100<¾。
