Inhibition of cytochrome P450 enzymes in the Australian brushtail possum, Trichosurus vulpecula: Comparison with that of the rat, rabbit, sheep and chicken

A comparative study was conducted of the inhibition of liver microsomal cytochrome P450 phase biotransformation enzyme activity of the Australian brushtail possum, rat, rabbit, sheep and chicken. The possum has caused considerable agricultural and ecological problems since its introduction to New Zealand. This work investigated species differences in cytochrome P450 inhibition by selected imidazole derivatives that may be exploited for designing a more species-specific method of toxicological control of the New Zealand possum population. The imidazole derivatives used were ketoconazole, clotrimazole, miconazole and cimetidine. The potency of these inhibitors varied, with clotrimazole and miconazole being most potent, followed by ketoconazole. Cimetidine was the least effective inhibitor. The inhibitory effect of imidazole derivatives on cytochrome P450 phase biotransformation enzymes appeared more effective in the possum than in other species. All inhibitors used produced type II spectra upon interaction with cytochrome P450 preparations. Possum and chicken microsomal preparations showed absorbancy maxima at 428 nm, rabbit and rat and 429 nm, and sheep at 431 nm.

Complexes of zinc phthalocyanine with monoaxially coordinated irnidazole-derivative ligands

Three complexes of zinc phthalocyanine (ZnPc) monoaxially ligated by imidazole, N-methylimidazole and N-(2-pyrimidinyl)imidazole were obtained in crystalline forms. Complexes containing imidazole and N-methylimidazole crystallise in the centrosymmetric space group of the triclinic system, while with the N-(2-pyrimidinyl)-imidazole complex crystallises in P2(1)/n space group of monoclinic system. Interaction of the electropositive polarised Zn centre of a planar ZnPc with nucleophilic ring nitrogen atom of imidazole derivatives leads to deviation of Zn form the N-4-plane of phthalocyaninato(2-) macrocycle by similar to 0.45 angstrom. Steric hindrance of the axial ligands of ZnPc-L complexes modify the pi center dot center dot center dot pi interactions between the Pc(2-) macrocycles when compared to that of the parent ZnPc pigment. The calculated threedimensional MESP maps are helpful for understanding of the interaction between the ZnPc and imidazole derivatives forming the monoaxially ligated complexes. Theoretical calculations of axial bonds energies and UV-Vis spectroscopic measurements in solutions also were performed. (C) 2016 Elsevier Ltd. All rights reserved.

A novel approach to study the inclusion mechanism of imidazole derivatives in micellar chromatography

A chromatographic approach was proposed to describe the existence of surfactant micelles in a surfactant/hydroorganic phosphate buffer mobile phase. Using this mixture as a mobile phase, a novel mathematical theory is presented to describe the inclusion mechanism of imidazole derivatives in surfactant micelles. Using this model, enthalpy, entropy and the Gibbs free energy were determined for two chromatographic chemical processes: (i) the transfer of the imidazole derivative from the mobile phase to the stationary phase; and (ii) the imidazole derivative inclusion in surfactant micelles. These thermodynamic data indicate that the main parameter determining chromatographic retention is distribution of the imidazole derivatives to micelles of surfactant while the interaction with the stationary phase play a minor role.

Fast and accurate predictions of heat of formation by G4MP2-SFM parameterization scheme: An application to imidazole derivatives

We proposed a new parameterization scheme, G4MP2-SFM, for the prediction of heat of formation by combining SFM (Systematic Fragmentation Method) and high accuracy G4MP2 theories. In an application to imidazole derivatives, we found that the overall MAD and RMSD of the particular G4MP2-SFM(opt) are 1.9 and 2.2 kcal/mol, respectively, demonstrating its high prediction accuracy. In addition, our parameterization scheme replaces the ab initio computations with a set of simple arithmetic, allowing fast predictions. Our new computational scheme can be of practical use in high throughput search for new high energy materials. (C) 2014 Elsevier B. V. All rights reserved.

Studies on molecular recognition of imidazole derivatives by novel chiral tyrosine tetraphenylporphinatozinc complex

Two kinds of novel chiral Zn porphyrin complexes were synthesized and characteried by means of elementary analysis, UV-Vis, H-1 NMR. Molecular recognition was studied between hosts and imidazole derivatives. Association constants of Zn (o-BocTyr) TAPP and Zn (p-BocTyr) TAPP with imidazoles increased in the sequence K (2-MeIm > K (Im) > K (N-MeIm) > K (2-Et-4-MeIm). Through circular dichroism spectra and theoretical calculation method, the chang of position in which imidazoles coordinated to host I was studied, it is important to study the structral characterization of porphyrin.

Thermal, spectral and biological investigation of new nickel complexes with imidazole derivatives

Four new Ni(II) complexes with acrylate and imidazole (Him) or imidazole derivatives [2-methylimidazole(2-MeIm)/5-methylimidazole(5-MeIm)/2-ethylimidazole(2-EtIm)] as ligands were prepared and characterized. All coordination compounds were characterized by elemental analysis, infrared (FTIR) and ultraviolet-visible-near-infrared (UV-Vis-NIR) spectroscopy, mass spectroscopy, magnetic moments measurements and thermal analysis (TG). The resulted complexes were formulated as follows: [Ni(HIm)(2)(acr)(2)] (1), [Ni(2-MeIm)(2)(acr)(2)(H2O)] center dot H2O (2), [Ni(5-MeIm)(2)(acr)(2)]center dot H2O. (3), [Ni(2-EtIm)(2)(acr)(2)(H2O)] center dot H2O (4). On the basis of magnetic moments measurements and on UV-Vis-NIR spectra, for all Ni(II) complexes was proposed an octahedral stereochemistry. Acrylate ions act as bidentate in complexes (1) and (3); meanwhile, in (2) and (4) they behave as bidentate and unidentate. Antimicrobial activity of complexes was investigated on ATCC reference and clinical microbial strains. The MIC (minimum inhibitory concentration) values revealed moderate antimicrobial activity of complex (1) against Enterococcus faecium and of complex (2) against Pseudomonas aeruginosa and Bacillus subtilis.

Tuning the Adsorption Interactions of Imidazole Derivatives with Specific Metal Cations

In this work, we report a computational study of the interactions between metal cations and imidazole derivatives in the gas phase. We first performed a systematic assessment of various density functionals and basis sets for predicting the binding energies between metal cations and the imidazoles. We find that the M11L functional in combination with the 6-311++G(d,p) basis set provides the best compromise between accuracy and computational cost with our metal…imidazole complexes. We then evaluated the binding of a series of metal cations, including Li+, Na+, K+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Ba2+, Hg2+, and Pb2+, with several substituted imidazole derivatives. We find that electron-donating groups increase the metal-binding energy, whereas electron-with-drawing groups decrease the metal-binding energy. Furthermore, the binding energy trends can be rationalized by the hardness of the metal cations and imidazole derivatives, providing a quick way to estimate the metal…imidazole binding strength. This insight can enable efficient screening protocols for identifying effective imidazole-based solvents and membranes for metal adsorption and provide a framework for understanding metal…imidazole interactions in biological systems.
