Description
技术领域
本发明属于药物化学领域,具体涉及一类4-磺酰亚胺-1H-吡咯类Mcl-1抑制剂及其抗肿瘤医药用途。
背景技术
细胞凋亡又称细胞程序性死亡,其对于清除有害细胞和潜在的危险细胞以及维持细胞内环境有重要作用。Mcl-1作为抗凋亡蛋白通常在肿瘤细胞中过表达,并且与癌症的发生和耐药性的产生密切相关,因而作为肿瘤治疗的潜在靶点被深入研究。
内源性凋亡通路中的一个重要过程是促凋亡蛋白Bax/Bak互相结合形成二聚体使线粒体外膜去极化,使得细胞色素c等凋亡因子外流,诱导下游凋亡信号通路转导。Mcl-1则能够通过其疏水沟槽与Bax/Bak结合抑制其二聚体的形成从而抑制细胞凋亡。
小分子的BH3模拟物能够模拟BH3结构域与Mcl-1蛋白的结合从而抑制Mcl-1与促凋亡蛋白的相互作用,这一策略被广泛地应用于Mcl-1小分子抑制剂的设计。近年来,越来越多小分子抑制剂被报道,一些具有高活性及良好成药性Mcl-1正在进行临床研究,有望成为新的癌症治疗药物。

实施例55:效果实施例
1、采用荧光偏正的方法测试(FP实验)测试化合物对Mcl-1的抑制活性
采用FP方法测试目标化合物对Mcl-1的抑制活性,蛋白终浓度为20nM,所选探针为FITC-Bak-BH3,探针浓度为10nM。测试使用384孔黑板(型号为Corning3676),测试终体积选择40μL,所测试化合物和FITC-Bak-BH3多肽荧光探针溶于DMSO(10mmol母液) 中备用。将化合物用HEPES缓冲液倍比稀释11个浓度梯度,每个孔板加入20μL稀释好的化合物,再依次加入10μL缓冲液稀释好的10nM探针和10μL12nM蛋白。每个化合物浓度设定两个复孔,实验设置空白对照(10μL探针+40μL buffer,记为Pmin)和阴性对照(10μL探针+10μL蛋白+20μLbuffer,记为Pmax)。之后在摇床上室温震摇孵育 30min,用SpectraMax Multi-ModeMicroplateReader (Molecular Devices)扫板,激发波长设置为485nm,发射波长设置为535nm,测试孔读数记为Pobs。抑制率计算公式为:抑制率(%) =[1-(Pobs-Pmin)/(Pmax-Pmin)]×100%,采用Graphpad Prism 6.0软件计算IC50。Ki按照以下公式进行计算:
Ki=[I]50/([L]50/Kd+[P]0/Kd+1)
其中[I]50代表化合物的半数抑制浓度,[L]50代表探针浓度,[P]0代表蛋白浓度,Kd代表蛋白与探针的解离常数。
测试结果表明大部分化合物具有Mcl-1低微摩尔级抑制活性,其中部分化合物具有纳摩尔级抑制活性,所有化合物在10微摩尔浓度下对Bcl-2蛋白均无明显抑制活性,结果见表1。

2、对肿瘤细胞的抗增殖实验(MTT实验)
测试本发明所述化合物DDO-8300、DDO-8301对人类多发性骨髓瘤细胞株H929细胞株、急性白血病细胞株Mv-4-11、乳腺癌细胞株SK-BR3、非小细胞肺癌细胞株NCI-H23抗增殖、慢性髓细胞白血病细胞株K562(对Mcl-1抑制剂不敏感)的抗增殖活性。方法:以H929细胞株为例,将肿瘤细胞细胞接种于96孔平板中(每孔约有4000个细胞),于37℃,5%CO2 条件下孵育24小时后,将不同浓度的化合物加入至细胞中,再培养72小时后,各小孔中分别加入20μl MTT的PBS溶液(浓度为5mg/ml),于37℃孵育4小时,除去MTT和培养基,每个小孔中分别加入150μL DMSO,于490nm下检测(采用Thermo Multiskan Spectrum读板器),测试结果用Graphpad Prism 6.0分析。
测试结果表明DDO-8300、DDO-8301对H929细胞、Mv4-11细胞活性较好,DDO-8301对K562细胞选择性较好,结果见表2。

我们使用HPLC方法测定化合物在人工胃肠液中孵育0.25、0.5、1、2、4、6、12小时后的含量,计算其降解剩余百分含量。37℃条件下,选取浓度为200μM的化合物分别在胃肠液中孵育指定的时间,根据上述色谱条件进行测定,记录其峰面积,计算剩余百分率。结果显示(图1、图2),化合物DDO-8300、DDO-8301在模拟人体胃肠道环境的溶液中比较稳定,受胃蛋白酶和胰蛋白酶的影响比较小。
上述实施例的作用在于具体介绍本发明的实质性内容,但本领域技术人员应当知道,不应将本发明的保护范围局限于该具体实施例。
