Description
技术领域
本发明涉及医药领域,具体涉及一种含喹啉基化合物、药物组合物以及其用途。
背景技术
血管内皮生长因子受体(vascular endothelial growth factor receptor,VEGFR)是受体酪氨酸激酶家族中的一员,通过与其配体血管内皮生长因子(vascularendothelial growth factor,VEGF)结合产生一系列生化和生理过程,最终促使新生血管形成。在正常血管中,血管生成因子和血管生成抑制因子保持平衡,而在肿瘤的生长过程中,VEGFR和VEGF的高表达破坏了这种平衡,促进了肿瘤新生血管的形成。研究表明,受体特异性的高表达以及新生血管形成是肿瘤生长的先决条件,恶性肿瘤的生长和转移都必须通过周围新生血管持续提供充足的营养和排泄废物,因此,VEGFR和VEGF的高表达与微血管的密度、肿瘤的增殖以及转移密切相关。由于VEGFR-2主要分布在血管内皮细胞内,如果阻断VEGFR的活性,可以在不影响正常细胞的条件下通过直接和间接途径抑制肿瘤的生长和转移,进而达到理想的抗肿瘤效果。目前,已有多个VEGFR抑制剂被美国FDA批准用于肿瘤的治疗,已经上市的VEGFR小分子抑制剂有Cabozantinib(XL184,BMS-907351)、舒尼替尼(sunitinib)、索拉非尼(sorafenib)和凡德他尼(vandetanib,ZD6474),进入临床研究的VEGFR小分子抑制剂约有20多种,其中进入III期临床阶段的有瓦他拉尼(vatalanib,PTK787/ZK222584)、AMG-706、帕唑帕尼(pazopanib)等。寻找对VEGFR-2具有高活性的小分子抑制剂成为肿瘤治疗领域的研究热点。
组蛋白去乙酰化酶(histone deacetylases,HDACs)与肿瘤的发生也密切相关,其抑制剂可以降低肿瘤细胞凋亡的阈值,具有广泛的抗肿瘤活性,并且可与多种抗肿瘤药物联合使用发挥协同作用。人组蛋白去乙酰化酶划分为四类:第一类包括HDAC1、HDAC2、HDAC3和HDAC8;第二类为HDAC4、HDAC5、HDAC7和HDAC9;HDAC6和HDAC10包含两个催化点,归为IIa类型;HDAC11属于第IV类,其催化中心包含与一类和二类HDAC共同的氨基酸残基,这11个HDAC亚型的催化点都存在锌离子。HDAC抑制剂在精神病学和神经学上作为情绪稳定剂和抗癫痫药具有很长的历史,用于神经退行性疾病,比如阿尔茨海默病、亨廷顿氏病、帕金森氏症的治疗正在研究中。HDAC抑制剂的另外一大类应用是作为抗癌药物,目前,已有2个HDAC抑制剂被美国FDA批准用于治疗皮肤T细胞淋巴瘤,分别是Vorinostat(SAHA)和Romidepsin(FK228),还有多个HDAC抑制剂如PXD-101(Phase II)、LBH589(Phase III)、MS-275(PhaseII)等尚处于临床研究阶段。
发表于国际顶级临床肿瘤学期刊J.Clin.Oncol.上的一项I期临床试验结果表明,HDAC抑制剂能有效逆转晚期实体瘤患者对VEGFR抑制剂产生的耐药性。联合用药虽然能有效克服肿瘤细胞异质性和适应性引起的对单靶点药物不敏感和耐药性问题,但也存在着不同药物间药代动力学性质差异、不良药物-药物相互作用以及患者依从性差等问题。而开发多靶点抗癌药物则有望在克服联合用药上述缺陷的同时,解决肿瘤对单靶点药物的不敏感和耐药性问题。

术语“元”是指构成环的骨架原子的个数。例如吡啶是六元环,吡咯是五元环。
术语“药学上可接受的”是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药物组合物”是指任选的混合有至少一种药学上可接受的化学成分或试剂的生物活性化合物,所述药学上可接受的化学成分或试剂即为“载体”,其有助于将化合物引入到细胞或组织中,包括但不限于稳定剂、稀释剂、悬浮剂、增稠剂和/或赋形剂。

效果评估
1.化合物HDAC6酶学活性(IC50)检测
利用HDAC6荧光分析法检测化合物对HDAC6酶学活性的抑制作用。具体操作如下:
将待测化合物用DMSO配制成10mM的储液。取10μl 10mM待测化合物储液用90μlDMSO稀释成为1mM的工作溶液,将化合物三倍梯度稀释,包括DMSO阴性对照共计11个浓度,每个浓度取3μl加入到197μl的反应缓冲液(20mM Hepes pH 8.0,137mM NaCl,2.7mM KCl,1mM MgCl2,0.05%BSA,0.5mM TCEP)中,混匀后取10μl加入到384孔板中,最终反应体系中化合物的浓度为10μM至0.51nM,做复孔。每孔加入10μl 3XHDAC溶液(BPS,Cat.50006,0.3nM),23℃孵育20分钟。之后加入3X底物溶液(Anaspec,Cat.61855,15μM),离心混合,23℃继续孵育90分钟。加入30μl胰蛋白酶/SAHA终止混合液(20mM Hepes pH 8.0,100mMNaCl,10mM SAHA,0.01mg/ml胰蛋白酶),23℃孵育60分钟终止反应。最后使用Envision进行进行荧光数据读取(390nm excitation,460nm emission),430nm的高数值表示酶活性较高,而430nm的低数值则表示酶活性受到抑制。最后用XLfit5软件来分析数据,并计算化合物的IC50值。伏立诺他(SAHA)为阳性参照化合物。结果如表1所示。

2.化合物VEGFR2酶学活性(IC50)检测
利用迁移率检测技术(Mobility shift assay),对VEGFR2(KDR)进行化合物的筛选。化合物起始测试浓度为1000nM,3倍稀释,10个浓度,复孔检测。以Nintedanib(Selleckchem,Cat.S1010)为阳性对照化合物。操作方法简述如下:将待测化合物与终浓度为0.5nM的激酶VEGFR2(Carna,Cat.08-191)在Optiplate-384F孔板混匀后室温孵育10分钟。之后加入终浓度为95μM的ATP及3μM的Kinase substrate 22(吉尔生化,Cat.112393)混匀后室温反应30分钟。加入终止检测液终止酶促反应后并用Caliper EZ ReaderII读取转化率。
数据分析:
其中:Conversion%_sample是样品的转化率读数;Conversion%_min:阴性对照孔均值,代表没有酶活孔的转化率读数;Conversion%_max:阳性对照孔比值均值,代表没有化合物抑制孔的转化率读数。
拟合量效曲线:以浓度的log值作为X轴,百分比抑制率为Y轴,采用分析软件GraphPad Prism 5的log(inhibitor)vs.response-Variable slope拟合量效曲线,从而得出各个化合物对酶活性的IC50值。结果如表2所示。
