Description
技术领域
本发明涉及药物化学领域,具体为一种抗癌喹喔啉嘧啶胺杂环化合物及其制备方法和应用。
背景技术
细胞增殖和生长受到细胞周期调控机制的严格控制,细胞分裂失调会导致细胞异常增殖,是癌症的关键标志之一,因此,靶向调节细胞周期的药物一直是研究热点。周期蛋白依赖性激酶(CDK)是一类依赖细胞周期蛋白(Cyclin)的丝氨酸/苏氨酸蛋白激酶,可作为催化亚基与Cyclin结合形成异二聚体,磷酸化对应底物驱动细胞周期。其中,CDK6与肿瘤关系密切,在肿瘤细胞中常见扩增现象,主要调控后生动物中G1期到S期的过渡,在细胞周期的G1期的前期,会与D型细胞周期蛋白结合表现出蛋白激酶活性,磷酸化视网膜母细胞瘤蛋白(RB)促进转录因子E2F的释放,加快细胞周期由G1期向S期的进展。因此,抑制CDK6可以减慢细胞周期进程,产生抗增殖和抗癌的作用。
莫洛尼小鼠白血病病毒前病毒整合激酶1(PIM1)是一种结构独特的丝氨酸/苏氨酸激酶,在多种恶性血液瘤和一些实体瘤中高度表达。PIM1激酶通过磷酸化不同的底物在不同阶段刺激细胞周期进程,如分别活化Cdc25A和Cdc25C加快G1期到S期和G2期到M期进程;磷酸化CDK抑制剂p27Kip1使其失活,将细胞周期阻滞在G1期,促进癌细胞凋亡等,是潜在的癌症治疗药物的作用靶标。我们发现了一种全新母核的喹喔啉嘧啶胺杂环化合物,能够对CDK6和PIM1产生抑制作用,发挥抗癌效果。
发明内容
本发明的目的是提供一种全新母核的喹喔啉嘧啶胺杂环化合物,对CDK6和PIM1产生抑制作用。本发明还提供了该化合物的具体制备方法和应用于制备喹喔啉嘧啶胺杂环化合物的制药应用。

三、生物学评价实验
(1)CDK6激酶活性分析检测方法
为考察实例化合物对CDK6/cyclinD1蛋白激酶的抑制作用,采用PerkinElmer公司的Lance Ultra方法进行检测。在检测板中将蛋白激酶、Ulight标记的多肽底物、ATP及化合物混合,并孵育反应。之后,加入EDTA终止反映,并加入铕(Eu)螯合物标记的抗体进行检测。本实验采用PerkinElmer公司的Envision仪器进行分析,模式为TR-FRET。在320/340nm波长激发后,可以发射665nm和615nm波长的荧光信号。Eu可以将能量转移至相邻的荧光物质Ulight受体上,再对该发射光进行检测。首先用DMSO将化合物溶解并稀释至2mM,然后3倍稀释10个浓度,使最终实验板中化合物浓度为10μM至0.508nM。再将CDK6/cyclinD1(LifeTechnologies)和Ulight-4E-BPI-peptide substrate(珀金埃尔默)分别用反应缓冲液(50mM Hepes PH 7.5,10mM MgCl2,0.01%Birj-35,1mM EDTA,2mM DTT)稀释至1nM和50nM,取5μl多肽和激酶混合液与100μl不同浓度的化合物在OptiPlate-384微孔板中混合,在室温下孵育15分中后加入5μl的350μM ATP溶液,室温孵育90min,最后加入10μL检测溶液(2nMEu-labeled antibody,10mM EDTA以及1*检测缓冲液)室温孵育60min后检测。IC50结果用IDBS公司的XLfit5进行分析。
测得的IC50值如下表1,从实验结果可以看出,本发明实例化合物对CDK6激酶活性具有很强的抑制活性。
表1本发明化合物对CDK6激酶活性的IC50测量值
(2)PIM1激酶活性分析检测方法
通过电泳迁移率变动分析检查化合物对PIM1激酶的抑制效果。测定在384孔板中进行,首先将30μM ATP和测试化合物添加到33ng/mL PIM1和1.5μM FAM-Pimtide(5FAM-ARKRRRHPSGPPTA,Caliper Life Sciences,Hopkinton,MA)中引发酶促反应(反应缓冲液为50mM Hepes(pH 7.4),10mM MgCl2,1mM DTT,1%蛋白酶抑制剂,1%磷酸酶抑制剂和0.01%Brij-35),室温下孵育2h后,添加140mM EDTA终止反应。分离获得的磷酸化和未磷酸化的肽并用Lab-Chip EZ Reader II(Caliper Life Science)检测。
测得的IC50值如下表2,从实验结果可以看出,本发明实例化合物对PIM1激酶活性具有很强的抑制活性。

2)向培养板加入梯度稀释的不同浓度的待测化合物溶液100μL,将培养板在37℃,5%CO2培养箱条件下孵育72小时;
3)孵育结束前4h,每孔加入20μL MTT溶液(5mg/mL)。孵育结束后,弃去各孔上清液,每孔加入150μL DMSO,细胞振荡仪上振荡10min,待结晶物充分溶解后用酶标仪测定OD570,抑制率=(对照组OD值-实验组OD值)/对照组OD值×100%;
4)得出数据后,GraphPad Prism 6拟合得出IC50。
本发明中的化合物对多种癌症细胞增殖活性的试验进行测定,测得的IC50值见表2。可以看出化合物对人乳腺癌(MCF-7、MDA-MB-231)细胞系、多发性骨髓瘤(RPMI8226)细胞系、白血病(HL-60、K562)细胞系、肺癌(A-549、非小细胞肺癌NCI-H1650)细胞系、胃癌(MGC-803)细胞系、卵巢癌(SK-OV-3)细胞系、人结肠癌(HT-29)细胞系、肝癌(HepG2)细胞系、胰腺癌(Panc-1)细胞系、人神经胶质瘤(U251)细胞系和前列腺癌(PC-3)细胞系等14种细胞具有增殖抑制作用。其中,实施例40对K562和HL-60白血病细胞增殖抑制的IC50值可达到1.026μM和1.07μM。

称取供试品置于无菌小瓶中,加入250mL DMSO,再加入10μL甲磺酸,溶解后,加入4.78mL 5%葡萄糖注射液,超声、振荡混匀,配制成2mg/mL的供试品溶液,以此溶液作为灌胃给药制剂。另外,取0.5mL 2mg/mL的供试品溶液,加入4.5mL的5%葡萄糖注射液,振荡混匀,配制成0.2mg/mL的供试品溶液,作为静脉注射给药制剂。
实施例40按5mg/kg和50mg/kg剂量分别对大鼠进行静脉注射给药和灌胃给药并在给药后,在给药前后既定时间取血并分离出血浆,测定血药浓度。根据灌胃给药测定结果,选取给药后2h取血以及心、肝、脾、肺、肾、胃、肠、脑、肌肉、附睾脂肪、睾丸等组织。建立HPLC-MS/MS方法测定给药后实施例41在大鼠血浆及组织中的浓度,利用WinNonlin统软件计算药动学参数,结果如表5。
结果表明实施例40具有吸收慢,代谢快,分布广的药动学特性,且其与组织蛋白的结合力较弱,较易再次释放入血,从而对药动学行为产生明显影响。且可快速且广泛分布到各个组织,血流丰富的组织如肝脏、脾脏、肺脏、肾脏、心脏中药物浓度较高,分别为30.27、10.71、31.69、12.60、5.13μg/g组织;另外,在肌肉中的浓度也达到1.31μg/g。
