Description
技术领域
本发明属于药物化学领域,更具体地,涉及一种Schizocommunin衍生物及其制备方法和应用。
背景技术
恶性肿瘤是危害人类健康和生命安全的一类主要疾病,据世界卫生组织 (WHO)统计,全球恶性肿瘤患者高达9050万人,且每年有1410万新增病例。每年有880万人死于癌症,而中国每年有接近200万人死于癌症。抗癌药物的研究和开发一直是药物化学家关注的热点。寻找高效、高选择性的抗癌药物是药物研发的重要方向之一。
化学疗法是治疗癌症的一种重要方法,其中较为经典且使用非常广泛的就是以双螺旋DNA为靶点或调控DNA复制等过程的化疗药物。但是,这类传统的靶向双螺旋DNA的化疗药物也会引起严重的毒副作用或耐药性。因此,基于核酸靶点开发高选择性和低毒副作用的抗肿瘤新药一直是国内外抗肿瘤研究的热点和难点。
核酸(包括DNA和RNA)是生命体内遗传信息储存和传递的载体,核酸多样性的二级结构也是很多重要生物学活动的调控元件。核酸的二级结构包括了 DNA中的B型、A型、Z型双螺旋,十字形DNA,三螺旋DNA(triplex)等, RNA中的发夹结构、三叶草结构、茎环结构等,以及在DNA和RNA中均可以形成的四链体结构(G-quadruplex)。其中,G-四链体(G-quadruplex)是由富G 碱基通过Hoogsteen氢键连接而堆叠形成的特殊核酸二级结构。由于结构的特殊性及其在多个重要生理过程中的调控作用,G-四链体已经成为近年来的研究热点。
端粒是一种位于染色体末端的特殊DNA-蛋白复合体,具有保护染色体免受基因丢失、非同源末端融合以及核酸酶降解的作用。端粒富含鸟嘌呤的单链悬垂结构,即d[GGG(TTAGGG)3]序列可以形成G-四链体结构(端粒G-四链体DNA)。小分子配体通过结合/稳定端粒G-四链体DNA,可以经多种途径抑制肿瘤细胞的端粒维持机制,达到抑制肿瘤细胞生长目的。端粒G-四链体配体抑制肿瘤细胞生长,主要包括以下3个方面:1)在细胞生长的过程中,端粒结合蛋白POT1 通过结合/拆散端粒G-四链体DNA,继而募集相关蛋白包括端粒酶开启了端粒的延长机制。小分子结合/稳定端粒G-四链体DNA可以阻止POT1与G-四链体DNA 的识别和结合,从而抑制了端粒DNA的延长。2)在端粒延长过程中,端粒酶需要线性、非折叠的端粒DNA作为引物。而端粒DNA在小分子作用下形成稳定的G-四螺旋结构后会抑制端粒酶对DNA的识别并表现为酶活性的丧失。3) 当小分子结合/稳定端粒G-四链体DNA时,可以阻止互补链与富G序列本身形成T-loop结构所需的双螺旋结构,通过这一抑制作用影响端粒的结构,从而加快端粒DNA的缩短和降解。因此,设计合成新型端粒G-四链体DNA的小分子配体,是开发抗肿瘤药物的新策略。

3.将10μL浓度2μm/L的化合物溶液与10μL400nmol/L的F21T混合,吹匀。
37℃放置1个小时,将得到的样品溶液转移到LightCycler毛细管中,使用RocheLightCycler 2型荧光定量PCR仪进行是实验。实验条件参数设置包括:激发波长设置为470nm,监测530nm的发射荧光强度;温度范围设置为37-99℃,升温间隔为1℃,平衡30秒后采样。实验结束后,Tm值计算用Origin软件拟合。
二、SPR实验方法:
1.配制缓冲溶液:
配制pH值为7.4,含有150mM KCl和0.005%Tween-20的50mM Tris-HCl 缓冲溶液,并用滤膜过滤(0.22μM),备用。
2.配制样品溶液:
用缓冲液将化合物梯度稀释到多种不同的浓度,备用。
3.DNA的固定:
将生物素标记的DNA(biotinylated duplex DNA和biotinylated HTG21)固定在带有链亲和素标记的芯片上。
4.实验过程:
结合过程:先将六种不同浓度的化合物溶液以25μL/min的速度流过芯片,持续5分钟;解离过程:化合物和DNA结合后,再用SPR缓冲液同样以25μL/min 的速度流过芯片,持续10分钟。每两次测试之间用1M的KCl冲洗芯片。

试验例2:实施例28~53合成的Schizocommunin衍生物对肿瘤细胞生长的抑制作用
选取部分代表性的化合物,对多种肿瘤细胞株采用MTT法进行体外细胞毒测定。在对数生长期的细胞中加入不同浓度的Schizocommunin衍生物,作用48 h后,加入MTT在37度孵育4小时,然后加入DMSO,测定其吸光度值。分别计算出抑制细胞生长50%时的化合物浓度,以IC50值表示,结果如表2所示。结果表明这系列化合物在体外对肿瘤细胞株有较强的抑制作用,可用于制备抗肿瘤药物。
