Synthesis of new analogs of benzotriazole, benzimidazole and phthalimide—potential inhibitors of human protein kinase CK2

New derivatives of 4,5,6,7-tetrabromo-1H-1,2,3-benzotriazole (TBBt), 4,5,6,7-tetrabromo-1H-benzimidazole (TBBi), and N-substituted tetrabromophthalimides were synthesized and their effect on the activity of human protein kinase CK2 was examined. The most active were derivatives with N-hydroxypropyl substituents (IC50 in 0.32–0.54 μM range) whereas derivatives of phthalimide were almost ineffective.
