2,6-Bis(2-benzimidazolyl)pyridine receptor for urea recognition

The use of 2,6-bis(2-benzimidazolyl)pyridine as a neutral receptor enables the formation of highly stable supramolecular complexes with urea via self-assembly and which were characterized by spectroscopy and X-ray diffraction analysis. This receptor utilizes the imine nitrogen located on its outer core in addition to the cavity to form hydrogen-bonded adducts with high binding affinity, thus providing a unique design for chemical and biological recognition.

Application In Synthesis of Bis(benzonitrile)palladium chloride

A series of platinum(II) complexes with tridentate ligands was synthesized and their interactions with Gquadruplex DNA within the c-myc gene promoter were evaluated. Complex 1, which has a flat planar 2,6-bis(benzimidazol-2-yl)pyridine (bzimpy) scaffold, was found to stabilize the c-myc G-quadruplex structure in a cellfree system. An in silico G-quadruplex DNA model has been constructed for structure-based virtual screening to develop new PtII-based complexes with superior inhibitory activities. By using complex 1 as the initial structure for hit-to-lead optimization, bzimpy and related 2,6-bis(pyrazol-3-yl) pyridine (dPzPy) scaffolds containing amine side-chains emerge as the top candidates. Six of the top-scoring complexes were synthesized and their interactions with c-myc G-quadruplex DNA have been investigated. The results revealed that all of the complexes have the ability to stabilize the c-myc G-quadruplex. Complex 3a ([PtIIL2R]+; L2 = 2,6bis[1-(3-piperidinepropyl)-1H-enzo[d]imidazol-2-yl]pyridine, R = Cl) displayed the strongest inhibition in a cell-free system (IC50 = 2.2 muM) and was 3.3-fold more potent than that of 1. Complexes 3a and 4a ([PtIIL3R]+; L3 = 2,6-bis[1-(3-morpholinopropyl)1H- pyrazol-3-yl]pyridine, R = Cl) were found to effectively inhibit c-myc gene expression in human hepatocarcinoma cells with IC50 values of 17 muM, whereas initial hit 1 displayed no significant effect on gene expression at concentrations up to 50 muM. Complexes 3a and 4a have a strong preference for Gquadruplex DNA over duplex DNA, as revealed by competition dialysis experiments and absorption titration; 3a and 4 a bind G-quadruplex DNA with binding constants (K) of approximately 106-107dm 3mol-1, which are at least an order of magnitude higher than the K values for duplex DNA. NMR spectroscopic titration experiments and molecular modeling showed that 4 a binds c-myc G-quadruplex DNA through an external end-stacking mode at the 3’terminal face of the G-quadruplex. Intriguingly, binding of c-myc G-quadruplex DNA by 3b is accompanied by an increase of up to 38-fold in photoluminescence intensity at lambdamax = 622 nm.

Three zinc(II) complexes presenting a ZnN6 chromophore and with peroxodisulfate as the counter-ion

The crystal structures of three Zn complexes with the peroxodisulfate anion (pds2-) acting as counter-ion are reported, namely bis(2,2?:6?,2?-terpyridine-k3N)zinc(II) hexaoxo-mu-peroxo-disulfate(VI) dihydrate N,N-dimethylformamide solvate, [Zn(C15H11N3)2](S2O 8)·2H2O·C3H7NO or [Zn(tpy)2](pds)·2H2O·DMF, (I), bis[2,4,6-tris(2-pyridyl)-1,3,-5-triazine-k2N2,N 4]zinc(II) hexaoxo-mu-peroxo-disulfate(VI) dihydrate, [Zn(C 18H12N6)2](S2O 8)·2H2O or [Zn(tpt)2](pds)·- 2H2O, (II), and bis[2,6-bis(1H-benzimidazol-2-yl-kN 3)-pyridine]zinc(II) hexaoxo-mu-peroxo-disulfate(VI) N,N-dimethylformamide trisolvate, [Zn(C19H13N 5)2](S2O8)·3C 3H7-NO or [Zn(bbp)2](pds)·3DMF, (III), where tpy is 2,2?:6?,2?-terpyridine, tpt is 2,4,6-tris(2-pyridyl)-1,3,5-triazine, bbp is 2,6-bis(1H-benzimidazol-2-yl) pyridine and DMF is N,N-dimethylformamide. The three structures are monomeric and present the Zn cation in a distorted octahedral environment, defined by two chelating tricoordinated ligands at almost right angles to each other. These cationic entities interact with an anionic network composed of hydrogen-bonded pds2- anions and solvate water and DMF molecules via Coulombic forces, and with each other through a number of pi-pi and C=C…pi contacts connecting the aromatic rings. The pds2- anions stabilize the structures in unprecedented counter-ion behaviour.

Metal drugs and the anticancer immune response

The immune system deploys a multitude of innate and adaptive mechanisms not only to ward off pathogens but also to prevent malignant transformation (“immune surveillance”). Hence, a clinically apparent tumor already reflects selection for those malignant cell clones capable of evading immune recognition (“immune evasion”). Metal drugs, besides their well-investigated cytotoxic anticancer effects, massively interact with the cancer-immune interface and can reverse important aspects of immune evasion. This topic has recently gained intense attention based on combination approaches with anticancer immunotherapy (e.g., immune checkpoint inhibitors), a strategy recently delivering first exciting results in clinical settings. This review summarizes the promising but still extremely fragmentary knowledge on the interplay of metal drugs with the fidelity of anticancer immune responses but also their role in adverse effects. It highlights that, at least in some cases, metal drugs can induce long-lasting anticancer immune responses. Important steps in this process comprise altered visibility and susceptibility of cancer cells toward innate and adaptive immunity, as well as direct impacts on immune cell populations and the tumor microenvironment. On the basis of the gathered information, we suggest initiating joint multidisciplinary programs to implement comprehensive immune analyses into strategies to develop novel and smart anticancer metal compounds.

A Novel Fluorescent Chemosensor Assembled with 2,6-Bis(2-Benzimidazolyl)Pyridine-Functionalized Nanoporous Silica-Type SBA-15 for Recognition of Hg2+ Ion in Aqueous Media

A novel fluorescent sensor for the recognition of Hg2+ in aqueous media was developed by assembly of 2,6-bis(2-benzimidazolyl) pyridine to SBA-15 nanoporous silica. The synthesized materials were characterized by techniques such as XRD, FT-IR, N2 adsorption?desorption, and TGA. Investigation of fluorescence properties of prepared material revealed emission spectra having maxima at 396 nm following excitation at 353 nm. It was found that the fluorescence intensity of the SBA-15 functionalized material remarkably quenched in the presence of Hg2+ ions in the pH range of 6?8, showing high selectively toward mercury ion among the more common tested cations. The fluorescence titration studies confirmed the linear relation between the concentration of Hg2+ ion and the fluorescence intensity quenching, and the lowest detection limit was calculated as 2.6 × 10?6 M.

The photoinduced CO-releasing properties of [RuLPy(CO)2Cl2] (1), [Ru(LPy2Bz-?2N1,N2)(CO)2Cl2] (2), and [Ru(LPy2Bz?Et-?3N1,N2,N3)(CO)2(Cl)]·PF6 (3) [LPy = 2-(2-pyridyl)benzimidazole, LPy2Bz = 2,6-bis(benzimidazole-2?-yl)pyridine, and LPy2Bz?Et = 2,6-bis(1-ethyl-benzimidazol-2?-yl)pyridine] in both DMSO and reduced myoglobin solution are reported. Complexes 1 and 2 release CO upon illumination at 365 nm. The bidentate chelation mode of LPy2Bz in 2 is changed into a meridional tridentate mode upon the ethylation of the benzimidazolic NH groups, 3. The extension of the conjugation system and the shift of the MLCT band into the visible region in 3 give rise to the RuII dicarbonyl complex capable of releasing CO at 468 nm. During illumination of 2, the chelation mode of LPy2Bz is changed from ?2N1,N2 to ?3N1,N2,N3, as monitored by solution NMR spectroscopic studies. The spectral properties were studied by TD-DFT calculations. The interaction of 1?3 with hen-egg-white lysozyme, as a biocompatible carrier, has been studied by ESI-MS and UV/Vis spectroscopy in the dark and upon illumination. Stable protein adducts containing the RuII(CO)2 moiety, capable of photoinduced release of CO, are formed.

Separation of lanthanides and actinides(III) using tridentate benzimidazole, benzoxazole and benzothiazole ligands

The ability of new hydrophobic tridentate ligands based on 2,6-bis(benzimidazol-2-yl)pyridine, 2,6-bis(benzoxazol-2-yl)pyridine and 2,6-bis(benzothiazol-2-yl)pyridine to selectively extract americium(III) from europium(III) was measured. The most promising ligand – 2,6-bis(benzoxazol-2-yl) -4-(2-decyl1-tetradecyloxy)pyridine L9 was found to give separation factors (SFAm/Eu) of up to 70 when used to extract cations from 0.02-0.10 M HNO3 into TPH in synergy with 2-bromodecanoic acid. Six structures of lanthanide complexes with 2,6-bis(benzoxazol-2-yl)pyridine L 6 were then determined to evaluate the types of species that are likely to be involved in the separation process. Three structural types were observed, namely [LnL6(NO3)3(H 2O)2], 11-coordinate only for La, [LnL6(NO 3)3 (CH3CN)], 10-coordinate for Pr, Nd and Eu and (LnL6(NO3)3(H2O)], L 10-coordinate for Eu and Gd. Quantum Mechanics calculations were carried out on the tridentate ligands to elucidate the conformational preferences of the ligands in the free state and protonated and diprotonated forms and to assess the electronic properties of the ligands for comparison with other terdentate ligands used in lanthanide/actinide separation processes.
