  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.

  四碘苯并咪唑类是蛋白激酶CK2的有效抑制剂

  摘要：

  通过将各自的苯并咪唑与碘和高碘酸在硫酸溶液中碘化，已经制备了一系列新的碘代苯并咪唑。另外几个2个取代基和N获得了4,5,6,7-四碘代苯并咪唑（TIBI）的-1-羧甲基取代的衍生物。为了比较，还合成了一些新的4,5,6,7-四溴苯并咪唑。已经评估了新化合物抑制蛋白激酶CK2的能力。结果表明，4,5,6,7-四碘代苯并咪唑类比四溴代类似物更有效地抑制CK2。分子建模支持的实验数据表明，四碘代苯并咪唑部分比各自的四溴和四氯化合物填充的结合腔更好。要注意的是，4,5,6,7-四碘代苯并咪唑（TIBI）是 迄今为止描述的最有效的CK2抑制剂（K i = 23 nM）之一。
