Description
技术领域
本发明属于医药技术领域,涉及一类具有抗肿瘤活性的特定化学结构的化合物,具体为具有2-吲哚酮-三唑类抗肿瘤化合物及其制备方法和应用。
背景技术
恶性肿瘤是危害人们生命健康的重大疾病,抗肿瘤药物的研发任重而道远。近年来,针对肿瘤细胞内特异性靶点设计靶向抗肿瘤药物已成为新一代抗肿瘤药物研发的趋势。许多研究证实,酪氨酸激酶在肿瘤的发生发展过程中发挥着极其重要的作用,它们的异常表达通常导致细胞增殖调节发生紊乱,致使肿瘤发生,并与肿瘤的侵袭、转移、肿瘤新生血管生成以及肿瘤的化疗抗药性密切相关。近年来研发的绝大多数靶向抗肿瘤药物为酪氨酸激酶抑制剂,目前小分子酪氨酸激酶抑制剂已成为药物研发的一个热点领域。
根据目前已上市或正在研究的小分子酪氨酸激酶抑制剂的化学结构和核心骨架分类,2-吲哚酮类是一类重要的小分子酪氨酸激酶抑制剂。其主要作用于血管内皮生长因子受体2(VEGFR-2),通过抑制肿瘤相关血管新生和阻断刺激肿瘤细胞生长作用,最终可以达到抑制肿瘤生长增殖、转移的目的。代表药物有司马沙尼(Semaxanib),舒尼替尼(Sunitinib)和Toceranib等。
本发明根据2-吲哚酮类小分子酪氨酸激酶抑制剂的结构特点,在2-吲哚酮核心骨架上创新性引入1,2,3-三唑结构,以期得到抗肿瘤活性更好的全新化合物,现有技术中并未见到相关结构的报道。

实施例29抑制酶活性与抗肿瘤细胞增殖实验。
(1)对本发明的化合物进行了酶活抑制实验,选择Sunitinib为阳性对照药。
使用ATP-Glo试剂盒(Promega,美国)测定进行VEGFR-2激酶测定。一般步骤如下:将VEGFR-2激酶(Invitrogen,美国),底物,ATP和受试化合物混合,并在96孔板中的总体积为30μL的最终缓冲液中孵育。包含底物和不含化合物的激酶的孔用作总反应对照。将测定板在黑暗中于30℃孵育1小时。用全波长多功能酶标仪进行检测以获得荧光值,该荧光值可进一步用于计算IC50值。
(2)对本发明的化合物进行了肿瘤细胞增殖抑制实验,试验方法采用常规的MTT法。
肿瘤细胞的培养:细胞株选用H460(人肺癌细胞),以RPMI1640+10%FBS+双抗(青霉素100单位/mL,链霉素100μg/mL)的培养液培养。
样品配制:用DMSO(Merck)溶解后,加入PBS(-)配成1000μg/mL的溶液或均匀的混悬液,然后用含DMSO的PBS(-)稀释。最终浓度分别为:5μM、2.5μM、1.25μM、0.625μM、0.3125μM。以Sunitinib作为对照。
细胞增殖抑制的测试方法:96孔板每孔加入浓度为4~5×104个/mL的细胞悬液100μL,置37℃,5%CO2培养箱内。24小时后,分别加入样品液和对照品液,10μL/孔,设双复孔,37℃,5%CO2作用24小时。每孔加入5mg/mL的MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑翁溴化物)溶液15μL,作用4小时后加入溶解液DMSO,100μL/孔,置培养箱内,溶解后用MK-2全自动酶标仪测490nm OD值,计算抑制率,实验结果见表1。
表1样品对VEGFR-2激酶抑制活性和人肺癌细胞(H460)的体外增殖抑制活性IC50值
以上实验数据显示,本发明中2-吲哚酮-三唑类抗肿瘤化合物具有较好的体外抗肿瘤活性,具有深入研究和开发新的抗肿瘤药物的价值,也为新药研发提供了更开阔的思路。
