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.
