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.

Studies on anhydrous proton conducting membranes based on imidazole derivatives and sulfonated polyimide

Anhydrous proton conducting membranes based on sulfonated polyimide (sPI) and imidazole derivatives were prepared. The acid-base composite membranes show a good chemical oxidation stability and high thermal stability. The addition of imidazole derivatives in sPIs can improve the chemical oxidation stability of the composite membranes enormously, and even much better than that of pure sPI. The proton conductivity of a typical sPI/xUI(2-undecylimidazole) composite membrane can reach 10(-3) S cm(-1) at 180 degrees C under the anhydrous condition. The proton conductivity of the acid-base composite membranes increases significantly with increasing content of UI. Moreover, UI in sPI/xUI composite membrane is difficult to be brought out by the vapor due to the existence of long hydrophobic moiety, which will improve the stability and lifetime of the membranes in the fuel cells.

Sensing rutile TiO2 through fluorescence of imidazole derivative

A new kind of imidazole derivative, 4,5-dipheny1-2(E)-styryl-1H-imidazole, has been synthesi zed. UV-vis absorption and fluorescence spectral studies show the interaction of the imidazole derivative with anatase and rutile phases of nanocrystalline TiO2. Anatase quenches the fluorescence emission of the imidazole derivative due to charge injection from the excited singlet state of imidazole derivative to the conduction band of anatase. On the other hand rutile enhances the fluorescence probably due to lowering of LUMO and HOMO levels of the imidazole derivative on ducking of the styryl moiety of tilt imidazole molecule into the void space of rutile TiO2, the HOMO and LUMO energies have been deduced from cyclic voltammetric results. The selective enhancement of fluorescence is useful to deduct and estimate nanocrystalline TiO2 rutile. (C) 2012 Elsevier B.V. All rights reserved.

Study of [2-(2 ‘-pyridyl)imidazole] complexes to confirm two main characteristic thermoanalytical behaviors of transition metal complexes based on imidazole derivatives

Imidazole derivative ligands are recognized as useful models for biomimetic complexes. Among the inorganic-organic hybrid complexes, those with derivatives of imidazole heterocyclic N-donor ligands are interesting for their framework. In previous studies of complexes with imidazole derivative ligands, our group reported two main thermally induced decomposition behaviors supporting two different systematic decomposition trends. In this work, one of these characteristic decomposition mechanisms was again found. The final goal of these serial studies is the possibility to provide, by the experimental evidences, a prediction model of thermal stability and decomposition typical behavior by comparing the structural characteristics of a precipitated complex. 2-(2’-Pyridyl)imidazole complexes with transition metal ions of general formula M(PyrIm)(2)(H2O)(2) (where M = Cu, Zn, Cd, Mn or Co) were synthesized, characterized and studied by thermoanalytical techniques coupled to mass spectrometry, to suggest their decomposition mechanism by Evolved Gas Analysis (EGA-MS). Complexes also showed the interesting possibility to be precipitated with two methanol molecules in the structure and to replace methanol molecules with water molecules under controlled conditions.

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.

Induction of non-diapause eggs by imidazole derivative KK-42 in the diapause type of Bombyx mori silkworm

The injection of an imidazole compound, KK-42, into fifth instar larvae of a silkworm (Bombyx mori, Daizo strain), which had been destined to produce diapause eggs, induced the moths to lay non-diapause eggs. The critical period for KK-42 injection in the induction of non-diapause eggs was 24 h to 72 h after the fourth ecdysis. Topical application of KK-42 to 48 h-old fifth instar larvae also induced non-diapause eggs.

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.

Stereocontrolled Ring-Opening of a Hindered Sulfamidate with Nitrogen-Containing Aromatic Heterocycles: Synthesis of Chiral Quaternary Imidazole Derivatives

This paper explores the role of a hindered cyclic sulfamidate derived from alpha-methylisoserine as an electrophile in a nucleophilic displacement reaction with nitrogen-containing aromatic heterocycles. Several imidazoles and pyrazole were tested as nucleophiles in the absence of an additional base to give the corresponding ring-opening compounds: We show that the process takes place by inversion of the configuration of the quaternary electrophilic center, retaining the enantiomeric excess of the starting sulfamidate. This reaction opens the way to obtain important quaternary imidazole derivatives such as an innovative type of bis-amino add related to histidinoalanine and a novel alpha,alpha-disubstituted beta-amino acid(beta(2,2)-amino acid)
