Syntheses and biological activity of chalcones-imidazole derivatives

A number of novel 13-membered chalcone-imidazole derivatives were prepared and have been synthesized and characterized by IR, H-1 NMR, C-13 NMR and elemental analysis, the results conformed well to expected structures. Substituted acetophenones and benzaldehydes were condensed using the Claisen-Schmidt base-catalyzed aldol condensation. Methyl on the aromatic ring of chalcones was brominated by NBS, and then the resulting mixture was reacted with imidazole to get the target compound. Several chalcones showed in vitro antibacterial activity against Gram-bacterial. The results showed that these are potential antibacterial compounds.

Clay-Supported 2-Phenyl-1H-Imidazole Derivatives for Heterogeneous Catalysis of Henry Reaction

Six derivatives (1-6) of 2-phenyl-1H-imidazole were tested as catalysts of Henry reaction. Three new (4-6) 2-phenyl-1H-imidazole derivatives, differently substituted (thio)ureas, were synthesized and determined by H-1 NMR and IR spectroscopy and elemental analysis. Two types of catalysis, homogeneous and heterogeneous, were examined and compared. Clay minerals Ca-MMT and Cu-MMT were used as solid supports for heterogeneous catalysis. The best results were obtained using compound 2 under conditions of heterogeneous method D from the point of view of yield and reaction time.

A four-component synthesis of highly substituted imidazole derivatives

Addition of lithiated methoxyallene 1 to imines 2 provided allenyl amines 3, which upon reaction with iodine and nitriles furnished dihydroimidazole derivatives 5. Treatment of these intermediates with strong acids such as trifluoromethane sulfonic acid afforded tetrasubstituted imidazole derivatives 6 in good overall yields. Subsequent base-promoted conversion of 1-iodovinyl-substituted compounds 6 into alkynyl-substituted imidazole derivatives 7 proceeded smoothly. Products 6 and 7 are versatile intermediates for further transformations such as palladium-catalyzed coupling reactions.

Displacement Reaction Using Ibuprofen in a Mixture of Bioactive Imidazole Derivative and Bovine Serum Albumin-a Fluorescence Quenching Study

The mutual interaction of imidazole derivative (PIPP) with bovine serum albumin (BSA) was investigated using photoluminescent studies. The fluorescence quenching mechanism of BSA by PIPP was analyzed and the binding constant was calculated. The binding distance between PIPP and BSA was obtained based on the theory of Forester’s non-radiation energy transfer. Displacement experiments were performed by using ibuprofen to identify PIPP binding site in BSA. The effect of some common ions on the binding constant between PIPP and BSA was also examined.

Kamlet-Taft and Catalan Studies of Some Novel Y-Shaped Imidazole Derivatives

Some novel Y-shaped imidazole derivatives were developed and characterized by NMR and mass spectral techniques. The photophysical properties of these imidazole derivatives were studied in several solvents. The Kamlet-Taft and Catalan’s solvent scales were found to be the most suitable for describing the solvatochromic shifts of the absorption and fluorescence emission. The adjusted coefficient representing the electron releasing ability or basicity of the solvent, C (beta) or C (SB) has a negative value, suggesting that the absorption and fluorescence bands shift to lower energies with the increasing electron-donating ability of the solvent. This effect can be interpreted in terms of the stabilization of the resonance structures of the chromophore. The observed lower fluorescence quantum yield may be due to an increase in the non-radiative deactivation rate constant. This is attributed to the loss of planarity in the excited state provided by the non co-planarity of the cinnamaldehyde ring attached to C(2) atom of the imidazole ring. Such a geometrical change in the excited state leads to an important Stokes shift, reducing the reabsorption and reemission effects in the detected emission in highly concentrated solutions.

Solid state hydrogen bonding in imidazole derivatives: a persistent tape motif

The Cambridge Structural Database was mined for non N-substituted, neutral imidazole derivatives. Solid states with metal centres bound to the imidazole nitrogen atoms and ionic species were not included. The N-N, hydrogen-bound, tape motif was found to be a structural trend in the solid-state of neutral imidazole derivatives in the presence of possible competing hydrogen bonds and in highly steric environments. A chemically intuitive set of parameters was chosen to characterize the relationships between imidazole rings in the solid states. The choice of structural parameters and the values these parameters take as a function of substitution patterns of imidazole derivatives was discussed. The complexities that can arise in the crude extraction of hydrogen bond strength from solid state data was discussed.

Photophysical studies of fused phenanthrimidazole derivatives as versatile pi-conjugated systems for potential NLO applications

Two new heterocyclic imidazole derivatives consists of pi-conjugated system attached to a phenanthrimidazole moiety have been synthesized in moderate yield by the condensation of 1,10-phenanthroline-5,6-dione with substituted aromatic aldehydes and 4-methoxyaniline in the presence of ammonium acetate in ethanol medium. The photophysical properties of these imidazole derivatives were studied in several solvents. These derivatives were evaluated concerning their solvatochromic properties and molecular optical nonlinearities. Their electric dipole moment (mu) and hyperpolarizability (beta) have been calculated theoretically and the results indicate that the extension of the pi-framework of the ligands has an effect on the NLO properties of these imidazole derivatives. The non-zero tensor components of these imidazole derivatives reveal that they possess potent non-linear optical (NLO) behavior. The energies of the HOMO and LUMO levels and the molecular electrostatic potential (MEP) energy surface studies have exploited the existence of intramolecular charge transfer (ICT) within the molecule.

Ligand-controlled Assembly of Cd(II) Metal-Organic Coordination Polymers Based on 3,5-Dinitrobenzoate and Flexible Bis(imidazole) Derivatives

Three new Cd(II) metal-organic coordination polymers, [Cd(bbi)(DNBA)(2)] (1), [Cd(bbbi)(DNBA)(2)] (2), and [Cd(dmbbbi)(DNBA)Cl]center dot 0.38H(2)O (3) [HDNBA = 3,5-dinitrobenzoic acid, bbi = 1-(1,4-butanediyl)bis(imidazole), bbbi = 1,1-(1,4-butanediyl)bis(benzimidazole), and dmbbbi = 1,1-(1,4-butanediyl)bis(5,6-dimethylbenzimidazole)], have been obtained from hydrothermal reactions of cadmium(II) chloride with the mixed ligands HDNBA and the three structurally related flexible bis(imidazole) derivatives. Single-crystal X-ray diffraction analyses have revealed that the dinuclear cadmium clusters acting as nodes interlinked by two mu(2)-carboxylic groups, are connected to four other clusters through bridging bbi (for 1) and bbbi (for 2) units to generate two extended two-dimensional (2-D) networks. Compound 3 features a 1-D zigzag chain structure. A systematic structural comparison of the title compounds indicates that the conformations and the steric hindrance of flexible bis(imidazole) derivatives each play an important role in the formation of the Cd(II) coordination polymers. The thermal stability of 1 and 2, and the luminescence behavior of 3 were also investigated.

Pro-apoptotic activity of imidazole derivatives mediated by up-regulation of Bax and activation of CAD in Ehrlich Ascites Tumor cells

In this study we report that, imidazole derivatives can induce apoptosis in Ehrlich ascites tumor (EAT) cells, which is clearly evident from annexin-V staining, flow cytometric analysis of cell cycle phase distribution and DNA fragmentation. Delineating further into molecular mechanisms leading to apoptosis of EAT cells, we observed that imidazole derivatives induce tumor cell death by the up-regulation of proto-oncoprotein Bax, release of cytochrome c from the mitochondria which activates caspase-3 and activated caspase-3 activates CAD (Caspase Activated DNase) causes DNA fragmentation. The status of Bcl-2 remains unaltered in EAT cells, and the under expression of Bcl-2 and up-regulation of Bax resulted in the increase of Bax: Bcl-2 ratio suggesting that Bcl-2 family involved in the control of apoptosis. These results suggest a further possible clinical application of imidazole derivatives as pro-apoptotic agent in association with conventional chemotherapeutic agents.
