Abstract
本发明涉及通式(I)所示的二价二氢喹唑啉酮类化合物及其药学上可接受的盐、水合物或前药,这些化合物作为Bromodomain蛋白二价抑制剂,有较好的抗肿瘤活性。本发明还涉及这些化合物的制备方法及含有它们的药物制剂,以及这些化合物和其药用组合物在治疗肿瘤中的应用。
Description
技术领域
本发明属于医药技术领域,具体而言,涉及新的二价二氢喹唑啉酮类化合物及其药学上可接受的盐、水合物或前药,这些化合物具有较好的Bromodomain蛋白抑制活性。本发明还公开了其制备方法及含有它们的药物制剂,以及这些化合物和其药用组合物在治疗肿瘤中的应用。
背景技术
目前药物设计以及药物治疗集中于单价或单一结合配体的发现,然而这类配体对于多结合域或者具有额外延伸部分的蛋白的结合能力较弱,不能实现完全结合。例如临床尚未对蛋白-蛋白相互作用进行成功地干预,通过同时与单一蛋白上两个结构域进行作用或者同时与两个不同蛋白的不同结构域作用。因而对于参与肿瘤发生的融合蛋白的调控,实现肿瘤治疗的目的是临床研究的热点。
Bromodomain结构域是一进化上高度保守的110个氨基酸的蛋白质功能结构域,可特异性识别组蛋白末端乙酰化的赖氨酸位点,通过染色质的组装和乙酰化而参与信号依赖性、非基础性的基因转录调控;Bromodomain亦可通过对转录因子等非组蛋白的乙酰化修饰而广泛参与细胞周期调控、细胞分化、信号转导等过程。如含Bromodomain结构域的BET家族包括四个蛋白(Brd2,Brd3,Brd4和BRDT),每个蛋白都包含两个独立的Bromodomain结构域用来识别组蛋白末端乙酰化的赖氨酸位点。BET蛋白能够调控多个下游基因的转录(如原癌基因c-MYC),而且BET蛋白还能识别并结合染色体上乙酰化修饰的转录因子(如GATA-1,NFκB),共同调节基因转录,影响许多疾病的发生和病理进程,尤其涉及肿瘤和炎症。因此,设计小分子BET抑制剂干扰BRD4与乙酰化组蛋白的结合,将有可能抑制c-MYC基因转录,达到抗肿瘤目的。通过对白血病细胞,淋巴瘤细胞和多发性骨髓瘤细胞研究发现,BET抑制剂(+)-JQ1能够影响BRD4与乙酰化组蛋白结合,显著下调c-MYC基因转录,抑制肿瘤细胞的增殖,且对正常细胞毒性较低,表明BET抑制剂有希望成为c-MYC高表达肿瘤的有效治疗药物。
当前药物设计以及药物治疗策略通常是集中于选择性的对单一蛋白结构域进行结合,而忽视了对这些结构域进行同时结合有可能实现特异性靶向能力和结合能力的提高。尽管抗体或者其他生物疗法能够特异性地靶向蛋白表面,然而由于抗体分子量较大,使得其口服利用度以及细胞渗透度较差。相反地,口服活性小分子通常由于其分子量过小,而不能够对蛋白-蛋白相互作用表面进行干预。
发明内容
本发明的目的在于提供一些新的二价二氢喹唑啉酮类化合物及其药学上可接受的盐、水合物或前药。这些化合物能够有效地结合具有Bromodomian结构的蛋白,从而调节下游的信号通路,发挥特定功能,可用于治疗与Bromodomain结构域蛋白相关的多种疾病。该类化合物可干扰具有Bromodomain结构域的Brd4与乙酰化组蛋白的结合,进而下调癌基因c-MYC和其相关靶基因的转录,可用于制备新型抗肿瘤药物。
本发明的目的还在于提供一种合成新的二价二氢喹唑啉酮类化合物的制备方法。
本发明的另一目的在于提供一种含有新的二价二氢喹唑啉酮类化合物的药物制剂。
