Two classes of fused nitrogen heterocycles were designed as CK2 inhibitor candidates on the basis of previous structure–activity relationship (SAR) studies. Various dipyrrolo[3,2-b:2′,3′-e]pyridine and benzo[g]indazole derivatives were prepared using transition-metal-catalysed cascade and/or multicomponent reactions. Biological evaluation of these candidates revealed that benzo[g]indazole is a promising scaffold for potent CK2 inhibitors. The inhibitory activities on cell proliferation of these potent CK2 inhibitors are also presented.
在以往结构-活性关系(SAR)研究的基础上,我们设计了两类融合氮杂环作为候选的 CK2 抑制剂。利用过渡金属催化的级联反应和/或多组分反应制备了各种二吡咯并[3,2-b:2′,3′-e]吡啶和苯并[g]吲唑衍生物。对这些候选化合物进行的生物学评估显示,苯并[g]吲唑是一种很有前途的强效 CK2 抑制剂支架。本文还介绍了这些强效 CK2 抑制剂对细胞增殖的抑制活性。
