Description
技术领域
本发明涉及药物化学领域,具体涉及6-氨磺酰基取代-β-咔啉-1-酮类衍生物、它们的制备方法、含有这些化合物的药用组合物以及它们的医疗用途,特别是作为细胞周期蛋白依赖性激酶2抑制剂的用途。
背景技术
恶性肿瘤是严重威胁人类生命的重大疾病之一,研究发现,几乎所有的肿瘤都与细胞周期调控机制紊乱有关,而细胞周期蛋白依赖激酶(cyclin-dependent kinases,CDKs)的过度活化是其中的一个重要原因。CDKs是一类重要的丝氨酸/苏氨酸蛋白激酶,与细胞周期蛋白(cyclin)结合后被激活,可催化底物磷酸化,驱动细胞周期各时相进程,依序完成DNA合成和有丝分裂,引起细胞的生长和增殖。目前,在人类细胞中,已发现13种细胞周期蛋白依赖性激酶(CDKs),它们分布在细胞周期的各个时相中,与细胞周期蛋白(cyclin)结合后发挥调节作用。在对细胞周期的研究中发现,细胞周期受多种调控因子调节,根据作用不同分为正相(刺激性)调节剂和负相(抑制性)调节剂。刺激性调节剂包括细胞周期素(cyclins)和细胞周期蛋白依赖性激酶(CDKs),抑制性细胞周期调节剂为细胞周期蛋白依赖性激酶抑制剂(CKIs)。其中CDKs是细胞周期调控的中心环节,cyclins和CKIs通过竞争性结合CDKs来调节细胞周期的进程。其过度激活或表达与肿瘤的发生发展具有密切的关系,抑制CDKs的活性,可抑制肿瘤的生长。普遍认为CDKs中的CDK2、CDK4和CDK6与肿瘤发生有密切关系,在肿瘤细胞中常有过度表达,如乳腺癌、食管癌和原发性肝癌等。
CDKs抑制剂可有效地诱导癌细胞凋亡,提高肿瘤和爱滋病化疗药物的敏感性,对CDKs的抑制成为抗肿瘤和抗艾滋病药物研究的新靶点。虽然在整个细胞周期进程中所有的CDKs都有着不可替代的作用,但由于CDK2是细胞周期越过G1/S期checkpoint,是启动S期DNA复制的关键调控因子,也是G2期运行的必要条件,因此选择性的CDK2抑制剂是当今CDKs抑制剂研究的主要方向。
目前国际上的研究主要集中在选择性CDK2小分子抑制剂的研究与开发,已有很多种类的抑制剂正处于临床前或临床试验阶段。
发明内容
本发明在研究了大量具有选择性的CDK2小分子抑制剂的基础上,以具有CDK2抑制活性的天然产物骆驼蓬碱(母核为β-咔啉环)为先导化合物,根据CDK2的晶体结构模型,利用计算机辅助药物设计手段搭建了CDK2抑制剂的构效关系模型和药物虚拟筛选模型,在此基础上设计并合成了一系列以6-氨磺酰基取代-β-咔啉-1-酮(β-咔啉-1-酮也称2,9-二氢-1H-吡啶并[3,4-b]吲哚-1-酮)为母核的全新结构的化合物,药理试验显示,本发明的β-咔啉-1-酮类衍生物均有不同程度的CDK2抑制活性。
