【实施例2】抗肿瘤活性测试
1测试方法
被测样品溶液的配制:测试样品为上述实施例1中合成的单体化合物1~196。准确称取适量样品,用DMSO配制成所需浓度的溶液,供活性测试。
细胞系及细胞的继代培养:活性测试采用人HL-60、A549、HepG2、MCF-7、Jurkat、MV-4-11、H1975、K562细胞系及其阿霉素耐药株K562/A02。各种细胞均用含10%FBS的RPMI-1640培养基,在37℃通入5%二氧化碳的培养箱中继代培养。
本实验采用MTT法测试评价了被测试样品对人HL-60、Jurkat、A549、H1975、HepG2和MCF-7癌细胞增殖的抑制活性。采用CCK8法测试评价了被测试样品对人MV-4-11、K562及其阿霉素耐药株K562/A02的细胞增殖抑制活性。
MTT法:活细胞线粒体中琥珀酸脱氢酶能够代谢还原黄色的溴化3-(4,5-二甲基噻唑)-2,5-二苯基四氮唑为蓝紫色的不溶于水的formazan,formazan的多少可通过酶标仪测定其吸收度求得。由于formazan的量与活细胞数成正比,所以可根据吸收度求出活细胞的数目,从而了解药物抑制或杀伤肿瘤细胞的能力。活性测试时,取对数生长期的细胞,用新鲜的RPMI-1640培养基配制成密度为每毫升5×104个细胞的细胞悬液,按每孔100ul接种于96孔板中,在37℃下培养12小时后,吸掉孔中培养基,每孔加入用200μL相应培养基稀释好的不同浓度的样品,继续培养72小时。然后加入12μL MTT溶液(5mg/L),再培养4小时,移出培养液后加入150μL DMSO溶解formazan,在570nm或者490nm处测定其吸收度。按照下式计算每个浓度下的细胞增殖抑制率(IR%):IR%=(OD空白对照–OD样品)/OD空白对照×100%。
CCK-8法:活细胞线粒体中琥珀酸脱氢酶能够代谢还原3-(2-甲氧基-4-硝基苯基)-2-(4-硝基苯基)-5-(2,4-二磺基苯)-2H-四唑单钠盐为具有高度水溶性的黄色甲臜产物(Formazan),生成的甲臜物的数量与活细胞的数量成正比。用酶联免疫检测仪在450nm波长处测定其光吸收值,可间接反映活细胞数量。由于formazan的量与活细胞数成正比,所以可根据吸收度求出活细胞的数目,从而了解药物抑制或杀伤肿瘤细胞的能力。活性测试时,取对数生长期的细胞,用新鲜的RPMI-1640培养基配制成密度为每毫升5×104个细胞的细胞悬液,按每孔100μL接种于96孔板中,在37℃下培养12小时后,吸掉孔中培养基,每孔加入用100μL相应培养基稀释好的不同浓度的样品,继续培养72小时。然后加入10μL CCK-8溶液,再培养6h,在450nm处测定其吸收度。按照公式“IR%=(OD空白对照–OD样品)/OD空白对照×100%”计算每个浓度下的细胞增殖抑制率(IR%)。
阿霉素(ADM)和吉非替尼为阳性对照组。

结论:试验结果表明,上述化合物对人癌细胞株HL-60、A549、Jurkat、MV-4-11、H1975、HepG2、MCF-7、K562和K562/A02均有良好的抑制活性,可以用作为预防和治疗上述肿瘤的药物。
特别是,上述化合物对耐药肿瘤的治疗作用,能够实现对特定耐药肿瘤的精确治疗。例如,采用表皮生长因子受体(EGFR)抑制剂吉非替尼或埃罗替尼治疗非小细胞肺癌(NSCLC),患者在治疗的起始阶段疗效好,但最终会因耐药而复发。H1975就是对吉非替尼或埃罗替尼获得性的EGFR-T790M/L858R肺腺癌耐药突变株。具有H1975抑制效果的化合物,对EGFR-T790M/L858R获得性耐药突变肺腺癌具有治疗作用,可用于此类肺癌患者的精确治疗。
