Multitarget Anticancer Agents Based on Histone Deacetylase and Protein Kinase CK2 inhibitors. Molecules 2020; 25:molecules25071497.

Abstract
The design of multitarget drugs (MTDs) has become an innovative approach for the search of effective treatments in complex diseases such as cancer. In this work, we communicate our efforts in the design of multi-targeting histone deacetylase (HDAC) and protein kinase CK2 inhibitors as a novel therapeutic strategy against cancer. Using tetrabromobenzotriazole (TBB) and 2-dimethylamino-4,5,6,7-tetrabromo-benzimidazole (DMAT) as scaffolds for CK2 inhibition, and a hydroxamate to coordinate the zinc atom present in the active site of HDAC (zinc binding group, ZBG), new multitarget inhibitors have been designed and synthesized. According to the in vitro assays, N-Hydroxy-6-(4,5,6,7-tetrabromo-2-(dimethylamino)-1H-benzo[d]imidazol-1-yl)hexanamide (11b) is the most interesting compound, with IC50 values of 0.66; 1.46 and 3.67 µM. for HDAC6; HDAC1 and CK2; respectively. Cellular assays on different cancer cell lines rendered promising results for N-Hydroxy-8-(4,5,6,7-tetrabromo-2-(dimethylamino)-1H-benzo[d]imidazol-1-yl)octanamide (11d). This inhibitor presented the highest cytotoxic activity, proapoptotic capability, and the best mitochondria-targeting and multidrug-circumventing properties, thus being the most promising drug candidate for further in vivo studies.

Abstract
In this article, we describe our efforts in the search of MMP2/CK2 dual targeting inhibitors. We have followed a rational drug design approach based on our experience in the selective inhibition of these two enzymes. We have successfully obtained highly active MMP2 (10, IC50 = 70 nM; 11, IC50 = 100 nM) and CK2 (16a, IC50 = 500 nM) inhibitors. However, structural fine tuning of these small molecules to simultaneously target both enzymes turned out to be an unattainable goal. Unexpectedly, we were lucky to identify new and selective MMP13 inhibitors (10, IC50 = 3.7 nM and 11, IC50 = 5.6 nM) with a novel TBB-derived scaffold. These compounds constitute an interesting starting point for further optimization.

Abstract
Three out of 16 newly synthesized 1,3-dimethylxanthine derivatives (proxyphylline analogues) exhibited consistencies between antifungal and anticancer properties. Proxyphylline possessing 1-(10H-phenothiazin-10-yl)propan-2-yl (6) and polybrominated benzimidazole (41) or benzotriazole moiety (42) remained selectively cidal against Candida albicans (lg R ≥ 3 at conc. of 31, 36 and 20 μM, respectively) however not against normal mammalian Vero cell line in vitro (IC50 ≥ 280 μM) and Galleria mellonella in vivo. These compounds also displayed moderate antineoplastic activity against human breast adenocarcinoma (MCF-7) cell line (EC50 = 80 μM) and high against peripheral blood T lymphoblast (CCRF-CEM) (EC50 = 6.3-6.5 μM). In addition, 6 and 42 exerted: (1) dual activity against fungal adhesion and damage mature biofilm; (2) necrosis of planktonic cells due to loss of membrane function and of structural integrity; (3) biochemical (inhibition of sessile cell respiration) and morphological changes in cell wall polysaccharide contents. Therefore, leading proxyphylline derivatives can be employed to prevent cancer-associated biofilm Candida infections.

Exploring the Pivotal Role of the CK2 Hinge Region Sub-Pocket in Binding with Tricyclic Quinolone Analogues by Computational Analysis. Molecules 2017; 22:molecules22050840. [PMID: 28534839 PMCID: PMC6154313 DOI: 10.3390/molecules22050840] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2017] [Revised: 05/12/2017] [Accepted: 05/17/2017] [Indexed: 11/21/2022] Open
Abstract
Protein kinase CK2 has been considered as an attractive therapeutic target of cancer therapy. The tricyclic quinoline compound CX-4945 is the first representative of CK2 inhibitors used in human clinical trials. The binding of non-2,6-naphtyridine substituted compounds 27e (IC50 > 500 nM) and 27h (IC50 > 1000 nM) to CK2 is abolished. However, the unbinding mechanisms due to the key pharmacophore group replacement of compounds 27e and 27h are unveiled. In the present work, combined computational analysis was performed to investigate the underlying structural basis of the low-affinity of two systems. As indicated in the results, the loss of hydrogen bonds between the non-2,6-naphtyridine and the hinge region destroyed the proper recognition of the two complexes. Besides, the allosteric mechanisms between the deviated ligands and the changed regions (G-loop, C-loop and β4/β5 loop) are proposed. Furthermore, energetic analysis was evaluated by detailed energy calculation and residue-based energy decomposition. More importantly, the summary of known polar pharmacophore groups elucidates the pivotal roles of hinge region sub-pocket in the binding of CK2 inhibitors. These results provide rational clues to the fragment-based design of more potent CK2 inhibitors.

Abstract
Protein kinase 2 (CK2), a member of the serine/threonine kinase family, has been established as a promising target in anticancer therapy. New derivatives of known CK2 inhibitors 4,5,6,7-tetrabromo-1H-benzimidazole (TBBi) and 4,5,6,7-tetrabromo-1H-benzotriazole (TBBt) bearing azide or substituted triazole groups were synthesized. Their influence on the activity of human recombinant CK2α and cytotoxicity against normal and cancer cell lines were evaluated. TBBi derivatives with triazole substituted with carboxyl substituent (7 and 10) exhibited the most potent inhibitory activity against CK2 with Ki value in the range of 1.96-0.91μM, respectively. New TBBi derivatives 2, 3, 5 and 9 have demonstrated the EC50, in the range of 12-25μM and 13-29μM respectively towards CCRF-CEM and MCF-7 cells. Derivatives TBBi decreased viability of cancer cells more efficiently than BALB cells and the biggest differences were observed for the azide substituted compounds 3 and 5. The effect of the most active compounds on the activity of eight off-target kinases was evaluated. Inhibitory efficiency of CK2-mediated p65 phosphorylation was demonstrated for the TBBi and compound 12.

Abstract
Discovered in late 1960, azoles are heterocyclic compounds class which constitute the largest group of available antifungal drugs. Particularly, the imidazole ring is the chemical component that confers activity to azoles. Triazoles are obtained by a slight modification of this ring and similar or improved activities as well as less adverse effects are reported for triazole derivatives. Consequently, it is not surprising that benzimidazole/benzotriazole derivatives have been found to be biologically active. Since benzimidazole has been widely investigated, this review is focused on defining the place of benzotriazole derivatives in biomedical research, highlighting their versatile biological properties, the mode of action and Structure Activity Relationship (SAR) studies for a variety of antimicrobial, antiparasitic, and even antitumor, choleretic, cholesterol-lowering agents.
