制备方法与用途

生物活性

DMAT 是一种有效的、特异性的 CK2 抑制剂,IC50 值为 130 nM。

靶点
  • CK2:0.13 μM (IC50, Human CK2)
  • PIM1:0.148 μM (IC50)
  • PIM2:1.6 μM (IC50)
  • PIM3:0.097 μM (IC50)
  • HIPK2:0.37 μM (IC50)
  • HIPK3:0.59 μM (IC50)
  • DYRK1a:0.41 μM (IC50)
  • DYRK2:0.35 μM (IC50)
  • DYRK3:1.7 μM (IC50)
  • PKD1:0.18 μM (IC50)
  • CDK2:0.64 μM (IC50)
体外研究

DMAT(1 μM 至 2.5 μM)在杀死抗雌激素耐药细胞方面比母细胞系 MCF-7 更有效,而后者是对抗雌激素敏感的。DMAT 导致抗雌激素耐药细胞死亡是通过 caspases 介导的。DMAT 抑制 CK2 活性,但这种抑制在 MCF-7、TAMR-1 和 182R-6 这三种细胞系中的相似。DMAT 在 10⁻⁴ mol/L 和 10⁻⁵ mol/L 浓度下对 H295R 细胞的增殖有影响,相较于对照组而言。DMAT(100 μM)显著增加 72 小时 H295R 细胞培养物上清液中的细胞凋亡。DMAT(1 nM 至 1 μM)显著降低 72 小时 H295R 细胞培养物中醛固酮的释放,相较于对照组而言。DMAT 还以与 ATP 竞争的方式抑制 PIM1,并且是除了 CK2 外其他激酶的有效抑制剂。

体内研究

DMAT 在体内的应用通过干扰肿瘤细胞增殖来减少移植瘤模型中的肿瘤生长。DMAT 给药后的生物化学参数和组织学检查显示肝脏组织未发生改变。

    名称:
    CK2α and CK2α′ subunits differ in their sensitivity to 4,5,6,7-tetrabromo- and 4,5,6,7-tetraiodo-1H-benzimidazole derivatives
    摘要:
    The goal of this study was to test the inhibitory activity of a series of tetrahalogenobenzimidazoles, including a number of novel derivatives, on individual catalytic subunits of human CK2. 4,5,6,7-tetrabromo- and 4,5,6,7-tetraiodo-1H-benzimidazoles and their newly obtained N-1- and 2-S-carboxyalkyl derivatives showed potent inhibitory activity against both these subunits. CK2 alpha' was up to 6 times more sensitive to the studied compounds than CK2 alpha. The investigated iododerivatives showed, in most cases, stronger inhibitory properties than the respective brominated congeners, but the differences showed considerable dependence on the protein substrate used.

  • Multitarget Anticancer Agents Based on Histone Deacetylase and Protein Kinase CK2 Inhibitors

    The design of multitarget drugs (MTDs) has become an innovative approach for the search of effective treatments in complex diseases such as cancer. In this work, we communicate our efforts in the design of multi-targeting histone deacetylase (HDAC) and protein kinase CK2 inhibitors as a novel therapeutic strategy against cancer. Using tetrabromobenzotriazole (TBB) and 2-dimethylamino-4,5,6,7-tetrabromo-benzimidazole (DMAT) as scaffolds for CK2 inhibition, and a hydroxamate to coordinate the zinc atom present in the active site of HDAC (zinc binding group, ZBG), new multitarget inhibitors have been designed and synthesized. According to the in vitro assays, N-Hydroxy-6-(4,5,6,7-tetrabromo-2-(dimethylamino)-1H-benzo[d]imidazol-1-yl)hexanamide (11b) is the most interesting compound, with IC50 values of 0.66; 1.46 and 3.67 µM. for HDAC6; HDAC1 and CK2; respectively. Cellular assays on different cancer cell lines rendered promising results for N-Hydroxy-8-(4,5,6,7-tetrabromo-2-(dimethylamino)-1H-benzo[d]imidazol-1-yl)octanamide (11d). This inhibitor presented the highest cytotoxic activity, proapoptotic capability, and the best mitochondria-targeting and multidrug-circumventing properties, thus being the most promising drug candidate for further in vivo studies.

    多靶点药物(MTDs)的设计已经成为在复杂疾病如癌症中寻找有效治疗方法的创新途径。在这项工作中,我们介绍了我们在设计多靶点组蛋白去乙酰化酶(HDAC)和蛋白激酶CK2抑制剂方面的努力,作为一种新的抗癌治疗策略。使用四溴苯并三唑(TBB)和2-二甲基氨基-4,5,6,7-四溴苯并咪唑(DMAT)作为CK2抑制的支架,并使用一个羟肟酸基团来配位HDAC活性位点中的锌原子(锌结合基团,ZBG),设计并合成了新的多靶点抑制剂。根据体外实验,N-羟基-6-(4,5,6,7-四溴-2-(二甲基氨基)-1H-苯并[d]咪唑-1-基)己酰胺(11b)是最有趣的化合物,其HDAC6;HDAC1和CK2的IC50值分别为0.66;1.46和3.67微米。对不同癌细胞系的细胞实验为N-羟基-8-(4,5,6,7-四溴-2-(二甲基氨基)-1H-苯并[d]咪唑-1-基)辛酰胺(11d)提供了有希望的结果。该抑制剂表现出最高的细胞毒活性、促凋亡能力,以及最佳的靶向线粒体和多药耐受性,因此是最有前景的药物候选化合物,值得进一步进行体内研究。
