Abstract Derivatives of 4,5,6,7-tetrabromobenzotriazole (TBBt) and 4,5,6,7-tetrabromobenzimidazole (TBBi) with IC50 in the low micromolar range and with high selectivity belong to the most promising inhibitors of protein kinase CK2 (casein kinase 2). Treatment of various cell lines with TBBt, TBBi or 2-dimethylamino-4,5,6,7-tetrabromo-1H-benzimidazole (DMAT) affected cell viability with simultaneous induction of apoptosis. The inhibitory activity of newly synthesized hydroxyalkyl derivatives of TBBi and TBBt depends on the length of the alkyl chain. The hydroxypropyl substituted derivatives show higher or similar inhibitory activity than the parent compounds when tested with human protein kinase CK2. To test the distribution of this class of compounds in mammals, [14C] TBBi was synthesized. This article was published in Mol Cell Biochem and referenced in Medicinal Chemistry
