技术领域
本发明属于药物化学领域,具体涉及萘内酰亚胺-多胺缀合物及其制备方法和用途。
背景技术
20世纪初,1,8-萘内酰胺(苯并[c,d]吲哚-2(H)-酮)作为一种合成还原染料和有机颜料的中间体被人们所利用。近几年来,萘内酰亚胺因其良好的生物活性逐渐被人们发掘出另一种潜在的应用价值---抗肿瘤试剂。文献报道萘内酰亚胺衍生物不但对多种肿瘤细胞增殖具有抑制作用,还可以有效抑制细胞周期蛋白依赖性激酶CDK2的活性,调控细胞周期各个环节的起始和进程,从而控制细胞凋亡。同时也有文献等报道萘内酰胺衍生物对抗肿瘤的重要靶点蛋白激酶FGFR1有强烈的抑制作用,因此,类萘内酰胺衍生物在抗肿瘤方面的应用有待进一步开发。同时萘内酰亚胺由于自身的共轭结构,可利用其特殊的光学性质进行细胞定位,发现其做作为药物作用的细胞亚器和靶点,以便研究其作用机制,具有开发成为分子探针的前景。
多胺是一种良好的药物载体,细胞内存在有多胺转运蛋白,可以将多胺修饰的药物运送至细胞内,提高药物的作用靶向性。同时,多胺的自由氮很容易和盐酸结合,形成水溶性的盐酸盐,使药物更好的作用于细胞。
因此,考虑到萘内酰亚胺和多胺的良好的生理活性,设想将两类通过化学键结合起来,形成缀合物,以期得到具有研究价值的抗肿瘤药物或诊断药物。

生物活性评价:
(1)化合物体外抑制肿瘤细胞生长活性测定:
选择实施例1-27制备的化合物,分别取对数生长期的HCT-116(人癌细胞)、HepG2(人肝癌细胞)、Hela(人宫颈癌细胞)、SMMC7721(人肝癌细胞)、CT-26(小鼠结肠癌细胞)、HT-29(人结肠癌细胞)、MCF-7(人乳腺癌细胞)七种肿瘤细胞株,以每孔5000-8000个细胞埋入96孔板,90μL/孔。培养24h后,加入10、50、100、300、500μM的样品,对每个细胞株,每个浓度都有四个复孔,在37℃,5v%CO2条件下培养48h后,加MTT 50μL(即噻唑蓝),继续培养4h后弃上清,每孔加入100μL DSMO,轻轻振荡15min,用酶标仪在570nm波长处测其吸光度A值。按下面的公式计算被测物对不同肿瘤细胞生长的抑制率,实验重复三次,并由统计软件求出IC50值。结果见表1和表2。
肿瘤细胞生长抑制率(%)=(OD对照-OD实验)/(OD对照-OD空白)×100%
表1实施例化合物1-8对肿瘤细胞CT-26、HT-29、MCF-7的生长抑制活性。
表2各实施例化合物对肿瘤细胞的生长抑制活性
由表1和2的数据可以看出,实施例1、2、4、5的化合物均对CT-26(小鼠结肠癌细胞)有较好的抑制能力,说明该系列化合物对结肠癌细胞具较好的选择性。实施例20和25对Hela(人宫颈癌细胞)有较强的选择性,实施例22对HCT-116(人结肠癌细胞)的增殖有较好抑制能力,尤其实施例19、21、26对所测试细胞株的增殖均具有较好的抑制能力,其中实施例21对HCT-116、Hela、HepG2、SMMC7721四种肿瘤细胞株生长的抑制能力均比阳性对照高3-5倍,基于其良好的体外活性,我们对实施例21做了体内肿瘤转移抑制能力的测试。
(2)实施例21对小鼠体内肿瘤肺转移的抑制测定:
取体外对数生长期的小鼠H22肝癌细胞,通过静脉注射向30只balbc小鼠注入H22细胞(5×106个/只),为确保在给药前所有小鼠的肿瘤平均生长,将其接种肿瘤后培养7天,取接种第7天后的小鼠模型,随机分为3组(每组10只),分别为生理盐水组、实施例21组、阳性对照(米托蒽醌)组。在第8天通过尾部静脉注射向小鼠分别注射实施例21(5mg/kg)、米托蒽醌(0.4mg/kg)和生理盐水(10mL/kg,阴性对照),并且持续7天。第15天以颈椎脱臼法处死小鼠,用解剖显微镜计数各肺叶的结节数。以下列公式计算肺转移抑制率:抑制率(%)=(1-治疗组平均肺结节数/阴性对照组平均肺结节数)×100%。实验结果见表3。
表3实施例21化合物抑制小鼠体内肿瘤肺转移活性
从表3可以看出,实施例21能有效抑制小鼠体内肿瘤肺转移,使小鼠体内肺转移结节明显减少,且对肿瘤转移的抑制能力高于临床抗肿瘤药物米托蒽醌,因此可以将其应用于制备治疗肿瘤转移的药物,所以该化合物是潜在的抗肿瘤肺转移药物,具有成药性的潜力。
上述实施例为本发明优选的实施方式,但本发明的实施方式并不受上述实施例的限制,其他的任何未背离本发明所作的改变均应为等效的置换方式,都包含在本发明的保护范围之内。
