HPLC retention and inclusion of imidazole derivatives using hydroxypropyl-beta-cyclodextrin as a mobile phase additive

Using the results of high performance liquid chromatography (HPLC), this paper investigates the separation and inclusion of a series of weakly polar imidazole derivatives, with hydroxypropyl-beta-cyclodextrin (HP-beta-CD) in the mobile phase over a wide range of column temperatures. These compounds are used for the treatment of onychomycosis. Gibbs Helmholtz parameters (Delta(Delta H) and Delta(Delta S)) of two adjacent imidazole peak on a chromatogram were determined from the graph of the logarithm of the separation factor, alpha, against the reciprocal of the temperature. A temperature dependent reversal of the elution order between a pair of imidazole derivatives was studied. The results revealed that the main parameter determining interactions between imidazole derivatives and HP-beta-CD increased as follows: HP-beta-CD double left right arrow solute hydrogen bonding interaction > HP-beta-CD double left right arrow solute complexation.

SYNTHESIS AND BIOLOGICAL EVALUATION OF NOVEL IMIDAZOLE DERIVATIVES AS POTENT ANTICONVULSANT AGENTS

In this study, we have made an attempt to synthesize novel imidazole derivatives (2a-h) and evaluate them for anticonvulsant activity using maximal electroshock method (MES). In the first step, substituted amines were allowed to react with substituted benzaldehyde in an equimolar amount with glacial acetic acid to form various substituted Schiff’s base intermediate (1a-h). Schiff’s base on treatment with benzil in the presence of ammonium acetate afforded corresponding imidazole derivatives (2a-h). The structure of the final analogs has been confirmed on the basis of elemental analysis, Fourier transform infrared spectroscopy (FT-IR), H-1 nuclear magnetic resonance (NMR), C-13 NMR, and mass spectra. Among all synthesized compounds, compounds 2a, 2f, and 2b were found to be most potent in comparison with standard phenytoin. [GRAPHICS]

Synthesis, cytotoxicity assessment, and interaction and docking of novel palladium(II) complexes of imidazole derivatives with human serum albumin

Imidazole analogs are the agents that attract both bioinorganic chemist and drug designer. Numerous methods have been proposed for synthesis of imidazole derivatives. In this study, a series of heterocyclic system with p-conjugated system such as 2-aryl-imidazo[4,5-f][1,10]phenanthroline analogs were synthesized. Then, three new palladium(II) complexes containing 2-(Furan-2-yl)-1H-Imidazo[4,5-f][1,10]Phenanthroline (FIP) and 2-(thiophen-2-yl)-1H-imidazo[4,5-f][1,10]phenanthroline (TIP) ligands were synthesized. The structures of the compounds, [Pd(Phen)(TIP)](NO3)(2), [Pd(Phen)(FIP)](NO3)(2), and [Pd(FIP)(2)]Cl were determined by spectroscopic methods and elemental analysis. Biological activity of the complexes synthesized was assessed against chronic myelogenous leukemia cell line, K562. Also, the interactions of human serum albumin with complexes were investigated using isothermal titration in the Tris buffer, pH7.4. According to the results obtained, it was found that there is a set of six binding sites for these complexes on HSA with positive cooperativity in the binding process. Docking technique was also applied to confirm the experimental results. The results showed that smaller complexes have higher interaction affinity.

Optoelectronic features of Y-shaped push-pull molecules based on imidazole

The paper involves organic light-emitting diodes fabricated with application of Y-shaped push-pull imidazole derivatives (chromophores) blended with poly(N-vinylcarbazole) as an organic active materials. The absorbance, photoluminescence and electroluminescence spectra of chromophores as well as electroluminescence-voltage, current-voltage and electroluminescence-voltage of the manufactured devices are presented. All investigated imidazole derivatives dissolved in tetrahydrofuran exhibited strong luminescence. The investigated organic light-emitting diodes exhibit red-shift in the main spectral maxima from 520 to 598 nm for photoluminescence and from 535 to 590 nm for electroluminescence depending on the type of imidazole derivative used. The electroluminescence spectra also proved to be very stable over the luminance range from 700 to 1600 cd/m(2), which is the luminance used for typical lighting applications.

High-performance isocyanate-epoxy materials

Purpose – The purpose of this paper is to investigate a new group of chemical compounds as accelerators (1-imidazole derivatives – tertiary amines) for curing of isocyanate-epoxy resin matrix. During heating no reaction between epoxy group and active hydrogen in presence 1-substituted imidazole derivatives was reported. Design/methodology/approach – The influence of accelerator type and content on curing process, thermal stability and chemical structure of hardened resin was determined using temperature modulated differential scanning calorimetry, dynamic mechanical analysis, heat deflection temperature, thermogravimetry (modulated and by activation energy – Ozawa method) and Fourier transform infrared spectroscopy. Additionally, the shear strength of epoxy compositions used as aluminium joints, at ambient and elevated temperature was determined. Findings – With catalyst content increase the oxazolidone or isocyanurate rings content decreased, indicating enhanced density of cross-linking and thermal resistance. For all imidazole derivatives used (i.e. 1-methylimizadole, 1-ethylimidazole and 1-butylimidazole) accelerating of the curing process was observed (significant decrease of the curing start temperature was reported). The thermal resistance and shear strength was improved with accelerator content (increase of isocyanurate rings amount, and consequently oxazolidone ones). Originality/value – Introducing of a new group of chemical compounds as new catalysts to isocyanate-epoxy resin material resulted in curing process acceleration, irrespectively of the imidazole derivative type.
