Description
技术领域:
本发明属于医药技术领域,具体涉及4,6-双取代吡啶[3,2-d]嘧啶类化合物及其药学上可接受的盐,化合物的制备方法,以该化合物为活性成分的药物组合物,以及在制备MNK抑制剂及其用于治疗和/或预防各种癌症和/或代谢性疾病的药物中的用途。
背景技术:
有丝分裂原激活的蛋白激酶作用激酶(MAP kinase-interacting kinase or MAPkinase signal-integrating kinase,Mnk)是一类丝氨酸/苏氨酸激酶,属于Ca2+/钙调蛋白依赖激酶家族,处于负责调控细胞存活增殖的MAPK信号通路下游。在肿瘤细胞中,MAPK信号通路的调节异常通常加剧细胞分裂、侵袭、存活等,其中细胞代谢和蛋白质合成的失调成为主要原因。真核细胞通过调节mRNA翻译而严格调控蛋白质合成,主要依赖于结合mRNA的5’7-甲基鸟苷酸的真核细胞起始因子4F(eIF4F)复合物,该复合物包括真核细胞起始因子4E(eIF4E),解旋酶4A(eIF4A)和骨架蛋白eIF4G,其中eIF4E作为该复合物中的关键因子,成为PI3K/Akt/mTOR和Ras/Raf/MEK/ERK信号通路介导的肿瘤存活及增殖的关键。ERK和p38激酶活化后,可激活MNK1/2,后者磷酸化底物蛋白eIF4E 209位的丝氨酸,继而提升在mRNA水平具有5’帽子结构的肿瘤相关蛋白(如c-Myc、细胞周期蛋白Cyclin D1、抗凋亡蛋白Mcl-1、Bcl-2,血管表皮生长因子VEGF、HDM2、缺氧诱导因子HIF-1α、基质金属蛋白酶MMP-3/9、SNAIL等)的核质转运及翻译过程。Mnk对eIF4E的磷酸化作用是后者发挥致癌作用的关键。Mnk通过介导eIF4E的磷酸化调控相关蛋白的翻译过程,这些蛋白在肿瘤细胞促存活、抗凋亡、促转移和耐药性机制中发挥着重要作用;除此之外,研究表明Mnk在代谢性疾病的发生发展过程中也发挥重要作用。开发Mnk抑制剂已经成为一种新兴的肿瘤和代谢性疾病治疗策略。
本发明人设计并合成了一系列4,6-双取代吡啶[3,2-d]嘧啶类衍生物,经酶活性筛选,所合成的化合物普遍具有很好的Mnk抑制活性,并且在实体瘤及血液癌细胞中均表现出明显的抗增殖活性。

本发明产物药理作用研究
Mnk激酶活性测试
采用上海CisBio公司的丝氨酸/苏氨酸激酶试剂盒进行Mnk激酶的活性筛选,以Staurosporine和CGP57380作为阳性对照药,Mnk蛋白购买自日本的Carna Biosciences。3μL配置好的0.33ng/μL Mnk1/2和4μL配置好的不同浓度的待测样品加入到混悬均匀的3μL反应混合液(1μM底物S1,39.2μMATP,10mM MgCl2,1mM二硫苏糖醇DTT和1×KinEASE酶缓冲液),室温下共孵育60min。根据试剂盒说明加入由5μL SA-XL665和5μL STKAb配置的反应混合物作为检测试剂终止酶反应,随后在室温下孵育60min。采用F500酶标仪(Tecan,Switzerland)读取在615和665nm处的HTRF信号的比值。测试样品的信号值减去空白的信号值,再比上未加药组的信号值,即得一定浓度下样品抑制酶活性的抑制率。通过抑制率并采用非线性回归计算IC50。
采用HTRF法考察目标化合物对Mnk1/2的半数抑制浓度(IC50值),结果见表:
表1化合物A01-A13对Mnk1/2的半数抑制浓度(IC50值)
表2化合物B01-B14对Mnk1/2的半数抑制浓度(IC50值)
表3化合物C01-C20对Mnk1/2在1μM和10μM的抑制率
表4化合物D01-D39对Mnk1/2的半数抑制浓度(IC50值)
表5化合物E01-E25对Mnk1/2的半数抑制浓度(IC50值)
表6化合物LB-16-LB-21对Mnk1/2的半数抑制浓度(IC50值)
细胞抗增殖活性测试
人结肠癌HCT-116细胞以每孔2,000个细胞的密度埋入96孔测试板中,在保持5%CO2的培养箱中37℃孵育24小时使其贴壁生长,随后加入不同浓度的待测试化合物。在培养箱中孵育96小时后,每孔中加入50μL的MTT溶液(2mg/mL),继续孵育4小时后弃去上层培养液,用200μL DMSO溶解四唑盐。96孔板在室温下轻轻震荡10分钟,然后用酶标仪测定在570nm波长下的吸光度,根据以下公式计算细胞的生长抑制率:
抑制率(%)=[(A加药-A空白)/A对照]×100%
GI50值为抑制一半细胞生长时所加的药物浓度,根据药物浓度和抑制率结果,采用GraphPad Prism 5软件通过量效曲线计算出GI50。
人白血病MOLM-13细胞按50,000细胞每孔的密度接种到24孔板中,加入设定浓度的待测样品,在保持5%CO2的培养箱中37℃共孵育3天。结束后将细胞重悬,吸取50μL细胞液与等体积的0.4%的台盼蓝溶液轻轻混合,吸取9μL的混合液置于血球计数板上,在显微镜下对总细胞数进行计数,生长抑制率由加药组的细胞数除以未加药组的细胞数计算得来。并根据抑制率及相应的浓度用GraphPad Prism 5软件进行非线性回归计算GI50值。
表7化合物A01-A13,B01-B14对HCT-116的GI50值
表8化合物D01-D39对HCT-116,MOLM-13的GI50值
表9化合物E01-E25,LB-01-LB-22对HCT-116的GI50值
注:“-”表示未检测到酶活性和细胞活性。
上述试验结果表明,本发明要保护的通式的化合物具有良好Mnk1/2激酶抑制作用,并且在实体瘤及血液癌细胞中均表现出明显的抗增殖活性。本发明的化合物具有很好的工业应用前景。
