The efficient method for the synthesis of novel 4,5,6,7-tetrabromo-1H- benzotriazole (TBBt) derivatives bearing a single stereogenic center has been developed. New compounds with a variety of substituents at the meta- and para-position of the phenyl ring are reported. All of the presented compounds were obtained using classical synthetic methods, such as bromination of benzotriazole, and its subsequent alkylation by monotosylated arylpropane-1,3-diols, which in turn have been synthesized through reduction of the corresponding prochiral β-keto esters, and the selective monotosylation of the primary hydroxyl group. The influence of the new and previously reported N-hydroxyalkyl TBBt derivatives on the activity of human protein kinase CK2α catalytic subunit was examined. The most active were derivatives with N-hydroxyalkyl substituents (IC50 in 0.80-7.35 μM range). A binding mode of (R)-1-(4,5,6,7-tetrabromo-2H-benzotriazol-2-yl)butan-3-ol 7b to hCK2α has been proposed based on in silico docking studies. Additionally, MTT-based cytotoxicity tests demonstrated high activities of novel 1-aryl-3-TBBt-propan-1-ol and 3-TBBt-propan-1,2-diol derivatives against human peripheral blood T lymphoblast (CCRF-CEM), and moderate anti-tumor activities against human breast adenocarcinoma (MCF7) cell lines.

A new class of phosphate and phosphonate prodrugs, called HepDirect prodrugs, is described that combines properties of rapid liver cleavage with high plasma and tissue stability to achieve increased drug levels in the liver. The prodrugs are substituted c
