ESIPT clubbed azo dyes as deep red emitting fluorescent molecular rotors: Photophysical properties, pH study, viscosity sensitivity, and DFT studies

Monoazo colorants with separate inbuilt ESIPT core were selected to examine the influence of azo group para to the hydroxyl group of ESIPT core and their effect on their spectral properties. They displayed absorption maxima in the visible region around 480-493 nm. 6a exhibited a broad peak along with a bathochromic shift of 40/90 nm in the solvents DMF and DMSO due to the existence of tautomeric equilibrium. They are sensitive to basic pH with a bathochromic shift of 30 nm. They are emissive in the deep red region (565-640 nm) accompanied by a Stokes shift of 62-121 nm in DMF and DMSO. More interestingly, they showed viscosity sensitive enhancement in emission in DMF: PEG 400 system in the deep red region. 6(a-c) exhibit higher quantum yield in viscous solvent i.e. 99% PEG 400 compared to that of DMF. 6a and 6c show viscosity sensitive (x) value of 0.522 and 0.513 respectively. The enhancement of emission intensity in the viscous solvent is due to charge transfer which was elucidated by polarity plots i.e. Lippert-Malaga, Mac-Rae, Weller’s and Rettig’s plots. DFT and TDDFT methods were used to correlate the experimental findings.

Ternary Zn(II) Complexes of Fluorescent Zinc Probes Zinpyr-1 and Zinbo-5 with the Low Molecular Weight Component of Exchangeable Cellular Zinc Pool

The intracellular exchangeable Zn(II) is usually measured with synthetic fluorescent zinc sensors. 4′,5′-Bis[bis-(2-pyridylmethyeaminomethy1]-2′,7′-dichlorofluorescein (Zin-pyr-1) is a sensor containing the fluorescein platform and a duplicated chelating unit. Its advantages include brightness and a relatively high affinity for Zn(II), K-d = 0.7 nM. 2-(4, 5- Dimethoxy-2-hydroxypheny1)-4-(2-pyridylmethypaminomethyl- benzoxazole (Zinbo-5) is a member of a growing family of ratiometric synthetic Zn(II) probes, offering a possibility to determine Zn(II) concentration independently of the sensor concentration. Cells, however, contain high, millimolar or nearly millimolar concentrations of low molecular weight ligands (LMWLs) capable of binding Zn(II) ions. Previously, we demonstrated that such LMWLs can perturb the performance of some fluorescent zinc sensors by competition and formation of ternary Zn(sensor) (LMWL) complexes. Here we tested Zinpyr1 and Zinbo-5 in this respect. Despite structural differences, both sensors formed such ternary complexes. We determined their stability constants K-c(tern) and performed numerical simulations of Zn(II) distributions at physiological concentrations of selected LMWLs. Glutamic acid was found to provide the strongest ternary complexes with either of the studied sensors. Zn(Zinpyr1)(Glu) was an absolutely dominant Zn(II)/Zinpyr-1 species (more than 96% of the exchangeable Zn(II)), and Zn(Zinbo5)(Glu) was the most abundant one (more than 40%) in these simulations. Our results indicate that under cellular conditions these sensors are able to report Zn(II) complexed to LMWLs rather than free Zn2+ ions. On the other hand, the specific affinity of Zn(Zinpyr-1) and Zn(Zinbo-5) for Glu creates interesting opportunities for determining glutamic acid in biological samples.

Synthesis, Biological Evaluation and Docking Studies of Benzoxazoles Derived from Thymoquinone

Thymoquinone (TQ), a natural compound with antimicrobial and antitumor activity, was used as the starting molecule for the preparation of 3-aminothymoquinone (ATQ) from which ten novel benzoxazole derivatives were prepared and characterized by elemental analysis, IR spectroscopy, mass spectrometry and NMR (H-1, C-13) spectroscopy in solution. The crystal structure of 4-methyl-2-phenyl-7-isopropyl-1,3-benzoxazole-5-ol (1a) has been determined by X-ray diffraction. All compounds were tested for their antibacterial, antifungal and antitumor activities. TQ and ATQ showed better antibacterial activity against tested Gram-positive and Gram-negative bacterial strains than benzoxazoles. ATQ had the most potent antifungal effect against Candida albicans, Saccharomyces cerevisiae and Aspergillus brasiliensis. Three benzoxazole derivatives and ATQ showed the highest antitumor activities. The most potent was 2-(4-fluorophenyl)-4-methyl-7-isopropyl-1,3-benzoxazole-5-ol (1f). Western blot analyses have shown that this compound inhibited phosphorylation of protein kinase B (Akt) and Insulin-like Growth Factor-1 Receptor (IGF1R ) in HeLa and HepG2 cells. The least toxic compound against normal fibroblast cells, which maintains similar antitumor activities as TQ, was 2-(4-chlorophenyl)-4-methyl-7-isopropyl-1,3-benzoxazole-5-ol (1e). Docking studies indicated that 1e and 1f have significant effects against selected receptors playing important roles in tumour survival.

N-Methylation of ortho-substituted aromatic amines with methanol catalyzed by 2-arylbenzo[d]oxazole NHC-Ir(iii) complexes

Seven new chelated cyclometalated Ir complexes of N-ABO,P, N-ABO,O, and N-ABO,C-(carbene) based on a rigid and tunable 2-arylbenzo[d]oxazole backbone have been prepared for the N-methylation of amines. Among these three coordinated modes, N-ABO,C-(carbene)-chelated iridium-based catalysts exhibited good performance in the monomethylation of aromatic amines with methanol (MeOH) as the green methylation reagent. The steric-modified synthesis of N-ABO,C-(carbene) complexes was described. The most active N-ABO,C-(carbene) complex with marginal steric hindrance as a catalyst was obtained from the benzoxazole ring without a substituent and methyl group of the benzimidazole ring on the N-heterocyclic carbene (NHC) ligand. A variety of amines including para- and meta-substituted aromatic amines, as well as heterocyclic amines, were formulated as suitable substrates. Importantly, this catalyst considerably promoted the yield of the N-methylation of ortho-substituted aromatic amines. Controlled kinetic experiments and deuterium-labeling reactions of these ortho-substituted amines were conducted under optimized conditions. On the basis of the experimental results, a plausible mechanism was proposed.

NEW ROUTE FOR THE SYNTHESES OF SOME NOVEL DERIVATIVES OF 3-ARYL BENZO[d]THIAZOLE-2(3H)-IMINE FROM HIGH SUBSTITUTED THIOUREAS

We have developed herein a new approach to the diverse synthesis of novel derivatives of 3-aryl benzo[d]thiazole-2(3H)-imines (3a-g), by a two-component reaction between diazonium salt (2) and various synthesized N-acyl-N’-aryl thioureas (1a-g), in the presence of sodium tert-butoxide as strong base. Finally, it resulted in the production of the desired products with a moderate yield. The chemical structures of these synthesized compounds were confirmed by various physico-chemical methods viz. FT-IR, 1H-NMR, 13C-NMR, and elemental analysis.

Fluorescent phenoxy benzoxazole complexes of zirconium and hafnium: synthesis, structure and photo-physical behaviour

A series of ten heteroleptic and homoleptic mononuclear Zr(iv) and Hf(iv) complexes bearing differently substituted phenoxy-benzoxazole ligands was synthesised. The complexes were characterised by H-1 and C-13{H-1} NMR spectroscopy as well as by elemental analyses and X-ray diffraction experiments. The molecular structures show octahedral or tetragonal-antiprismatic coordination motifs at the metal atom. The crystal packing patterns depend on the substitution of the ligands. The intermolecular interactions in the solid state are governed by weak – interactions, and are also dependent on the ligand structure. Photo-physical investigations reveal that all ten complexes show a ligand-centered fluorescence with emission maxima in the blue region of the electromagnetic spectrum.
