abstract = {Protein kinase CK2 is a promising therapeutic target,
especially in oncology. Over the years, various inhibitors
have been developed, with polyhalogenated scaffolds emerging
as a particularly effective class. Halogens like bromine and
chlorine enhance inhibitor stability by forming additional
interactions within the ATP pocket. Among halogenated
scaffolds, benzotriazole and benzimidazole have led to
potent molecules such as 4,5,6,7-tetrabromo-1H-benzotriazole
(IC50 = 300 nM) and
4,5,6,7-tetrabromo-2-(dimethylamino)benzimidazole (IC50 =
140 nM). Modifications, including
4,5,6-tribromo-7-ethyl-1H-benzotriazole (IC50 = 160 nM),
further improved activity. Changing scaffolds while
retaining halogens has enabled design of new inhibitors.
Flavonols, dibenzofuranones, and the indeno[1,2-b]indole
scaffold are key examples. Halogenation of the reference
molecule
5-isopropyl-5,6,7,8-tetrahydroindeno[1,2-b]indole-9,10-dione
(4b, IC50 = 360 nM) significantly boosted potency. The
study focused on introducing four halogens, yielding to the
compound
1,2,3,4-tetrabromo-5-isopropyl-5,6,7,8-tetrahydroindeno[1,2-b]indole-9,10-dione
(MC11), with an IC50 of 16 nM. Co-crystallography revealed
how bromine atoms enhance binding, and MC11 demonstrated
strong in cellulo activity, particularly against leukemic
cell lines like IPC-Bcl2.},
