Abnormal activation of the mTOR signaling pathway is a common feature of various tumorigenesis and development, and thus has become a hot spot for the development of anti-tumor inhibitors.
  • mTOR has at least two functional complexes, mTORCl and mTORC2, which mediate both associated and independent biosignal functions.

Description

吡啶并嘧啶或嘧啶并嘧啶类化合物、其制备方法、药物组合 物及其用途 技术领域
本发明属于药物化学领域。具体而言,本发明涉及一类吡啶并嘧啶或嘧啶并嘧啶类化 合物或其异构体或其药学上可接受的盐、 酯、前药或溶剂合物, 其制备方法, 药物组合物 及其在制备 mTOR抑制剂中的用途。 该类化合物或其药物组合物作为 mTOR抑制剂可用 于治疗由 PBK-AKT-mTOR信号通路功能失调而导致的疾病或病症。
背景技术
近年来的研究发现, PBK-Akt-mTOR信号通路在肿瘤细胞生长、 增殖、 侵袭和转移 中起关键作用, 阻断细胞内的 PBK-Akt-mTOR信号通路能够抑制肿瘤细胞增殖甚至促进 肿瘤细胞凋亡。 在多种人类肿瘤中, PBK-Akt-mTOR信号通路中多个关键节点蛋白因编 码基因存在突变或扩增而过度激活, 如上游受体型酪氨酸激酶的突变和扩增, 编码 pllOct 催化亚基的 PIK3CA基因在多种肿瘤中存在突变和扩增, Akt和 PDK1的过度活化以及负 调控因子 PTEN普遍缺失。
哺乳动物雷帕霉素靶蛋白 (mTOR)是 Akt重要的底物之一, 属于磷脂酰肌醇 -3-激酶相 关激酶 (PIKK)家族的一个非经典丝氨酸 /苏氨酸蛋白激酶。 mTOR信号通路是调控细胞生 长与增殖的一个关键通路,该通路将从营养分子、能量状态以及生长因子传来的信号整合 在一起, 能够调控大量生命过程。 mTOR信号通路的异常激活是多种肿瘤发生和发展的 共性, 因而已成为抗肿瘤抑制剂研发的热点。
然而, 研究发现 mTOR至少存在两种功能性复合物, mTORCl和 mTORC2, 它们介 导既关联又独立的生物信号功能。 临床上使用的雷帕霉素类药物 (包括雷帕霉素及其类似 物)通过变构结合到 mTORCl催化位点附近的 FKBP12蛋白结合位点 (FKBP12-rapamycin binding domain, FRB), 发挥部分抑制 mTOR 蛋白的作用。 这些化合物不能直接抑制 mTORC2, 也不能完全阻滞 mTORCl介导的所有信号。 尽管雷帕霉素类药物已在某些瘤 谱中显示出一定的临床疗效, 但这类药物的作用方式并不能完全发挥 mTOR靶向抗肿瘤 药物的潜力。 特别是, 在一些主要的实体瘤中, mTORC2介导的 AKT的过磷酸 (活化)对 于肿瘤的维持和生长至关重要, 但 mTORC2不能被雷帕霉素类药物抑制。
开发 ATP竞争性及特异性 mTOR小分子抑制剂为多种癌症治疗提供了可能。 与雷帕 霉素类似物相比, 近期报道的一些 ATP竞争性抑制剂对肿瘤细胞生长和存活、 蛋白质合 成、 生物能量代谢等已经显示出更强的抑制作用。 在动物实验中, 该类药物对 MDA361 乳腺癌、 U87MG胶质瘤、 A549和 H1975肺癌、 A498和 786-0肾癌有很强的单药抗肿瘤 活性。
综上所述, 鉴于多种瘤谱中都涉及到 mTOR信号通路, 开发更有效的 mTOR抑制剂 为新型广谱抗肿瘤药物提供了新的思路和策略。 目前已有数个 mTOR抑制剂进入临床研 究阶段,这预示 ATP竞争性 mTOR抑制剂有可能成为新一代的抗肿瘤药物进入临床使用。
本发明的发明人己确定 mTOR抑制剂是 ATP竞争性抑制剂, 因而其作用机制是非雷 帕霉素样的化合物。另外, 本发明的发明人在原有已报道的化合物的基础上, 通过合理设 计, 综合考虑化合物的水溶性、代谢稳定性等因素, 得到了一类新型吡啶并嘧啶或嘧啶并 嘧啶类化合物。 该类化合物在酶、 细胞水平上均能显示较好的 mTOR抑制活性。 经过进 一步的优化和筛选后, 有望研发成为制备简便、 活性更高的抗肿瘤药物。
