Description
技术领域
本发明涉及生物医药领域,具体地本发明涉及一种偶氮芳基脲类衍生物及其制备方法和应用。
背景技术
恶性肿瘤亦称为癌症,通常由控制细胞生长增殖机制失常而引起的疾病。肿瘤的持续生长、迁移和侵染离不开新生血管的营养供给,新生血管的形成在肿瘤的发生、发展和转移过程中起着重要的作用。肿瘤血管生成是所有实体瘤的共同特征。有数据表明,恶性肿瘤的生长和转移必须依赖丰富的营养供给,若无血管生成,体外培养的肿瘤组织生长体积不超过4mm3,体内肿瘤不超过1~2mm3。血管内皮生长因子(VEGF)及其受体VEGFR能特异性地促进内皮细胞的分裂、增殖和迁移,在肿瘤新生血管的过程中发挥着重要的作用。因此,VEGF、VEGFR成为目前癌症治疗应用最广泛的靶点。近年来,化学小分子靶向药物发展迅速,寻找新的小分子药物及探索到新的作用靶标十分迫切。

实施例19
1.本发明化合物的抗肿瘤活性测试
实验原理:MTT(3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide)比色法,是一种检测细胞存活和生长的方法。其检测原理为活细胞线粒体中的琥珀酸脱氢酶能使外源性MTT还原为水不溶性的蓝紫色结晶甲臜并沉积在细胞中,而死细胞无此功能。二甲基亚砜(DMSO)能溶解细胞中的甲瓒,用Synergy NEO全功能酶标仪在570nm及630nm双波长处测定其光吸收值,可间接反映活细胞数量。在一定细胞数范围内,MTT结晶形成的量与细胞数成正比。该方法已广泛用于一些生物活性因子的活性检测、大规模的抗肿瘤药物筛选、细胞毒性试验以及肿瘤放射敏感性测定等。
2.抗肿瘤活性实验
试样:实施例化合物;细胞系:人肝癌细胞细胞HepG2、人结肠癌细胞HCT 116和人胃癌细胞MGC-803;试剂:5mg mL-1MTT溶液,DMEM培养液、新生牛血清;胰酶;96孔培养板;二甲基亚砜;
实验操作:1)收集对数期细胞,调整细胞悬液浓度,每孔加100μl,铺板使待测细胞密度调至50%,边缘孔用无菌PBS填充;2)5%CO2,37℃孵育12h,吸除原有的培养基;加入培养基配制的不同浓度的实施例化合物(以0.1%的DMSO作助溶剂),共设4个平行孔,不加任何药物的对照孔加200μl培养基;3)5%CO2,37℃孵育48h,置显微镜下观察;4)弃去培养液,小心用PBS洗1遍后,每孔加入20μl 5mg mL-1的MTT,继续避光孵育4h;5)终止培养,小心吸去孔内培养液;6)每孔加入150μl DMSO,置摇床上低速振荡60s,使结晶物充分溶解。用全自动多功能酶标仪检测在570nm和630nm处各孔的OD值。
3.抗肿瘤活性评价
1)细胞抑制率计算:
细胞抑制率(%)=(正常OD570-630值-加药OD570-630值)/正常OD570-630值×100%
2)IC50值计算
试样浓度与细胞抑制率线性回归,利用软件计算试样对细胞的半数抑制浓度IC50值。
