Description
技术领域
本发明涉及治疗恶性肿瘤相关药物领域。具体而言,本发明涉及一种用于治疗恶性肿瘤的含三氮唑环的稠环对苯醌类二聚体化合物及其制备方法或含有它们的药物组合,以及其在医药上的用途。
背景技术
肿瘤是机体在各种致瘤因素作用下,局部组织细胞增生所形成的新生物,是当今全球致死率最高的疾病之一。现阶段,用于治疗恶性肿瘤的药物主要有:细胞毒药物、小分子靶向药物、抗体类药物、免疫检查点抑制剂和激素类药物等。然而,随着肿瘤耐药性的产生,临床一线用药很难有效杀灭患者体内的肿瘤细胞,达到预期治疗效果。因此,基于新机制、新靶点的抗肿瘤药物研发具有重大意义。众所周知,异常的细胞分裂是肿瘤细胞最显著的特征之一。Cdc25磷酸酶(cell division cyclin 25phosphatase)是一种细胞分裂周期基因所表达的调控蛋白,其可以促进细胞周期的进程并在多种肿瘤细胞中过量表达。因此,有效抑制Cdc25磷酸酶的活性可以有效抑制肿瘤细胞的分裂增殖。但现阶段还未有靶向于Cdc25磷酸酶的药物上市,因此靶向Cdc25磷酸酶的抗肿瘤新药研发具有重要研究价值。NSC663284是一种Cdc25磷酸酶抑制剂,由于其对Cdc25磷酸酶的活性及亚型选择性较差。因此对其进行进一步地结构优化,以期获得活性和选择性均由于NSC663284的新型Cdc25磷酸酶抑制剂。
本发明公开了一类新颖的含三氮唑环的稠环对苯醌类二聚体衍生物,此类化合物在现有技术中未见相关报道。

表4.目标化合物抑酶活性复筛结果

实施例6:目标化合物抗肿瘤细胞活性测试
实验原理:如图2所示,抗肿瘤细胞活性测试采用了经典的Cell counting kit-8assay(CCK-8)方法。其检测原理是利用WST-8化合物在电子耦合试剂存在的情况下,可以被细胞内脱氢酶还原成水溶性的橙黄色甲瓒化合物。甲瓒量与活细胞数量成正比,即细胞增殖越多越快,则颜色越深;细胞毒性越大,则颜色越浅。对于同样的细胞,颜色的深浅和细胞数目呈线性关系。(Britton D,Yahiro L,Cullen M,Kerwin J,Kopecka H,NadzanA.Pharmacol Biochem Behav 1989;34(4):779-83)
实验方法:(1)细胞种板:将待测细胞均匀接种于96孔培养板中,每孔加入100μL细胞悬液(约1000-5000个细胞,根据细胞的大小、细胞增殖速度的快慢等因素进行调节),细胞接种完放置于37℃5%CO2恒温培养箱中培养过夜使之充分贴壁。之后加入不同浓度的待测化合物,使其终浓度为0.08、0.4、2、10、50μM。同时设立DMSO空白对照组,保证各孔中DMSO浓度≤3‰。每个浓度设5个复孔,37℃,5%CO2恒温培养箱中使药物作用48h后进行检测。(2)加入CCK-8:检测时每孔加入20μL CCK-8溶液。以DMSO空白对照组加入CCK-8溶液的孔作为空白对照。(3)孵育显色:加好CCK-8的96孔板在细胞培养箱内继续孵育0.5-4小时。(4)测定结果:96孔板在酶标仪中于450nm处测定吸光度。
实验结果:如下表所示,五个化合物的抗肿瘤活性远弱于临床用药紫杉醇,也稍弱于阳性对照NSC663284。其中,化合物其中,化合物10对乳腺癌细胞MDA-MB-231活性最好,IC50为4.25±0.27μM,略优于阳性对照。14和15对乳腺癌细胞MCF-7的活性尚可,IC50分别为4.81±0.37μM、6.72±0.21μM。作为新结构类型的分子,值得进一步研究。
