Physicochemical and solvatochromic analysis of an imidazole derivative as NLO material

Bioactive imidazole derivative, 2-(2,4-difluorophenyl)-1-phenyl-1H-imidazo[4,54][1,10]phenanthroline, has been synthesized and characterized by IR, UV-vis, NMR and elemental (CHN) analysis. The electric dipole moment (mu) and the hyperpolarizability (beta) have been studied both experimentally and theoretically, which reveals that the synthesized imidazole derivative possesses non-linear optical (NLO) behavior. This chromophore possess more appropriate ratio of off-diagonal versus diagonal beta tensorial component (r=beta(xyy)/beta(xxx) = -0.19) which reflects the in plane nonlinearity anisotropy. Since they have largest mu beta(0) value, the reported imidazole can be used as potential NLO material. Within this context, reasonable conclusions concerning the steric hindrance in the chromospheres, push-pull character, hyperpolarizability of the imidazole and their application as NLO materials will be drawn. The solvent effect on the absorption and fluorescence bands was analyzed by a multi-component linear regression in which several solvent parameters were analyzed simultaneously.

Iron-Phosphonate Nanomaterial: As a Novel and Efficient Organic-Inorganic Hybrid Catalyst for Solvent-Free Synthesis of Tri-Substituted Imidazole Derivatives

In this study, organic-metal nanocatalyst was synthesized by reacting ferric(Iota Iota) chloride with organic phosphonate ligand. The particle size was controlled with the help of the surfactant. Nanoparticle structure was analyzed using Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), dispersive X-ray (EDX), Brunauer-Emmett-Teller (BET) isotherm and X-ray diffraction (XRD) spectra. Next, its catalytic activity was investigated in the synthesis of heterocyclic compounds (2,4,5-trisubstituted imidazoles derivatives). Under optimal conditions, the products were obtained with good efficiency and short time. Products identification were evaluated using physical data, FT-IR, H-1 and (CNMR)-C-13 analysis. The results show that the new method, namely the use of iron-phosphonate nanostructures, is effective for the synthesis of trisubstituted imidazole derivatives. This method has many advantages such as short reaction time, high yield, solvent free conditions, recyclability of the catalyst, and easy workup.

Imidazole derivatives as angiotensin II AT1 receptor blockers: Benchmarks, drug-like calculations and quantitative structure-activity relationships modeling

We performed benchmark studies on the molecular geometry, electron properties and vibrational analysis of imidazole using semi-empirical, density functional theory and post Hartree-Fock methods. These studies validated the use of AM1 for the treatment of larger systems. Then, we treated the structural, physical and chemical relationships for a series of imidazole derivatives acting as angiotensin II AT1 receptor blockers using AM1. QSAR studies were done for these imidazole derivatives using a combination of various physicochemical descriptors. A multiple linear regression procedure was used to design the relationships between molecular descriptor and the activity of imidazole derivatives. Results validate the derived QSAR model.

Two novel imidazole derivatives, 2-chloro-4,5-dimethyl-1-phenyl-1H-imidazole (C11H11ClN2)(PHENYLI) and 2-chloro-4,5-dimethyl-1-(o-tolyl)-1H-imidazole (C12H13ClN2) (TOLYLI), have been obtained by a procedure based on solvent-free synthesis pathway. Newly synthetized imidazole derivatives have been characterized experimentally by IR, FT-Raman and NMR techniques, while their reactive properties have been predicted on the basis of density functional theory (DFT) calculations and molecular dynamics (MD) simulations. The NLO behavior of the title compounds is greater than that of the standard NLO material urea. MEP analysis gives the most reactive sites in the molecules.

Interaction of human serum albumin with novel imidazole derivatives studied by spectroscopy and molecular docking

This study was a detailed characterization of the interaction of a series of imidazole derivatives with a model transport protein, human serum albumin (HSA). Fluorescence and time-resolved fluorescence results showed the existence of a static quenching mode for the HSA-imidazole derivative interaction. The binding constant at 296 K was in the order of 10(4) M-1, showing high affinity between the imidazole derivatives and HSA. A site marker competition study combined with molecular docking revealed that the imidazole derivatives bound to subdomain IIA of HSA (Sudlow’s site I). Furthermore, the results of synchronous, 3D, Fourier transform infrared, circular dichroism and UV-vis spectroscopy demonstrated that the secondary structure of HSA was altered in the presence of the imidazole derivatives. The specific binding distance, r, between the donor and acceptor was obtained according to fluorescence resonance energy transfer. Copyright (c) 2015 John Wiley & Sons, Ltd.

Antifugal Action of Imidazole Derivatives from New Pharmaceutical Forms on Various Strains of Candida

The antifungal activity of imidazole derivatives was tested on three types of Candida, respectively C. albicans, C. sake, and C. glabrata. The antifungal activity was compared with the activity of miconazole nitrate in 16 new formulations of oral biomucoadhesive tablets, with the purpose of being used in oral candidiasis. All the 16 formulations of biomucoadhesive tablets which contain 25 mg miconazole have a good antifungal action; the diameter of the inhibition area is over 20 mm in all the three strains of Candida. The second goal was to compare the activity of miconazole nitrate with other antifungal substances: clotrimazole (benzyl imidazole derivative), nistatin (polyenic macrolide), econazole (phenyl – ethyl – imidazole derivative), and fluconazole (triazole derivative). Good results, obtained by measuring the diameter of the inhibition area, were shown by econazole, with a diameter of over 22 mm, but this imidazole derivative does not penetrate the stratum corneum well enough, which implies a much longer treatment than miconazole. The third goal was the assessment of the antifungal activity of the 16 formulations of biomucoadhesive tablets by means of establishing the minimum inhibitory concentration (MIC) and of minimum fungicide concentration (MFC).
