Abstract
Description
技术领域
本发明属于抗肿瘤药物的合成技术领域,具体涉及一类新型的嘧啶衍生物,以及它们在制备抗肿瘤药物中的用途。
背景技术
据全球最新报告,癌症发病率排名第一的是肺癌,而肺癌患者中约80%~85%归类到非小细胞肺癌(NSCLC)。过去对于NSCLC治疗方法主要有手术治疗、放射治疗、化学治疗等,这些治疗方法在杀死癌细胞的同时,还对患者的身体造成不可逆的伤害,使得患者的生活质量大大的降低。随着相关技术的不断发展,使得癌症治疗手段不断改进,由一味的利用细胞毒性药物治疗转变为针对癌细胞的靶向治疗。靶向治疗是设计相应的治疗药物,使药物进入体内特异性地与致癌靶点相结合而发生作用,使肿瘤细胞特异性死亡,而不波及肿瘤细胞周围的正常组织细胞的一种治疗方法。这一方法成为肿瘤治疗的有效手段,在众多的分子靶标中,蛋白酪氨酸激酶(TK)是目前效果明显且前景广阔的靶点之一。
表皮生长因子受体(EGFR)的过度表达和异常活化,使得细胞过度生长,导致细胞发生癌变。大量研究表明EGFR酪氨酸激酶抑制剂(TKI)可竞争性抑制三腺苷(ATP)与酪氨酸激酶结合,抑制酪氨酸激酶的活性,从而达到抑制肿瘤细胞增殖的作用。目前已经上市且疗效比较好的小分子酪氨酸激酶抑制剂有拉帕替尼(Lapatinib)、奥斯替尼(Osimertinib)和罗西替尼(Rociletinib)等药物。虽然这些药物在治疗过程的前期起到一定的治疗效果,但长时间使用会产生不同程度的耐药性,使得药效降低。

本发明的嘧啶类衍生物在制备抗肿瘤药物中的应用,具体试验情况如下:
1、细胞株
人结肠癌细胞SW480、人非小细胞肺癌细胞A549、人皮肤鳞状癌细胞A431和人肺癌细胞NCI-H1975均购自中国科学院上海细胞库。
2、试剂和材料
MTT(MPBIO)、96孔细胞培养板(CorningCostar)、胎牛血清(Gibco)、DMEM(Dulbecco’s Modified Eagle Medium powder,high glucose,Gibco BRL,Gibco)、青霉素、链霉素(碧云天)、胰蛋白酶消化液(碧云天)、酶标仪(PE Enspire)。
3、实验步骤
(1)细胞培养
实验中肿瘤细胞SW480、A549、A431和NCI-H1975所用细胞培养基为含有10%(v/v)胎牛血清、100units/mL青霉素、100μg/mL链霉素和2mmol/LL-谷氨酰胺的DMEM培养基。细胞被置于饱和湿度、37℃、5%CO2温箱中培养。每隔2~3天传代一次。
(2)抗肿瘤活性检测
化合物1~34对肿瘤细胞的生长抑制活性利用MTT法进行测定。分别取对数生长期的人肿瘤细胞,用0.25%的胰蛋白酶消化液消化、离心、重悬后计数,制备细胞悬液,调整细胞悬液浓度为2.0×104~5×104个/mL。取细胞悬液接种于96孔培养板中(100μL/孔),置饱和湿度、37℃和5%CO2培养箱中培养24h。用细胞培养基稀释受试化合物至所需浓度,加入已接种人肿瘤细胞的96孔培养板中(100μL/孔),DMSO终浓度为0.5%,置于培养箱中培养72h。将MTT加入96孔板中(20μL/孔),培养箱中反应4h。吸弃孔内液体,加入DMSO(150μL/孔),摇床上震荡10min,使甲臜完全溶解。然后用酶标仪测定570nm波长处的吸光度(OD值),630nm波长处的吸光度作为参比,以相应溶剂作为对照,按下式计算受试化合物对肿瘤细胞生长抑制率:
肿瘤细胞生长抑制率%=[1-(ODs-ODNC)/(ODPC-ODNC)]×100%
其中:ODS表示样品孔的吸光度值(细胞+待测化合物+MTT);ODPC表示对照孔的吸光度值(细胞+DMSO+MTT);ODNC表示调零孔的吸光度值(细胞培养基+DMSO+MTT);ODs=OD570s-OD630s;ODPC=OD570PC-OD630PC;ODNC=OD570NC-OD630NC。
采用GraphpadPrism5拟合受试化合物对肿瘤细胞生长的抑制曲线,并得出IC50值。每组设置3个复孔,至少重复3次。
4、实验结果
以临床使用的抗肿瘤药物吉非替尼(Gefitinib)为阳性对照,实验结果如表1所示。
表1受试化合物抑制肿瘤细胞增殖的IC50(μmol/L)
表中“-”表示活性未测试。
由表1中的数据可见,受试化合物9、23、25、26、28对人结肠癌细胞SW480、人非小细胞肺癌细胞A549、人皮肤鳞状癌细胞A431和人肺癌细胞NCI-H1975的增殖都具有较好的抑制作用,且其活性优于Gefitinib;受试化合物18、20、29、32、34对人结肠癌细胞SW480、人非小细胞肺癌细胞A549和人肺癌细胞NCI-H1975的增殖具有较好的抑制作用,且其效果优于Gefitinib;受试化合物4、10、15、22、24对人结肠癌细胞SW480、人非小细胞肺癌细胞A549的增殖都有较好的抑制作用,且其效果优于Gefitinib;受试化合物21对人非小细胞肺癌细胞A549的增殖具有较好的抑制作用,且其效果优于Gefitinib;受试化合物2、8对人结肠癌细胞SW480的增殖具有较好的抑制作用,且其效果优于Gefitinib。活性数据表明,本发明化合物表现出较强的抑制肿瘤细胞增殖的作用,可用于制备抗肿瘤药物。
