Enhanced corrosion resistance of mild steel in sulphuric acid medium by imidazole derivative: Experimental and computational studies

The inhibition action of the imidazole derivative on the corrosion of mild steel in 0.5 M Sulphuric acid was investigated by weight loss, polarization, Impedance and SEM. The PZC of mild steel was studied by AC impedance method. The polarization experiment revealed that IDZ is of mixed-type but slightly anodic control. Weight loss results obtained revealed that the imidazoline derivatives performed excellently as corrosion inhibitor with efficiency above 70% at 20ppm at 303 K. The optimum period of inhibition for IDZ was determined by weight loss studies. Its adsorption on mild steel obeys Tempkin isotherm. Quantum chemical parameters and Mulliken charge densities on the optimized structure of imidazoline derivative were calculated using GAUSSIAN 09 with B3LYP / 6-31G (d,p) basis set.

A study on the binding interaction between the imidazole derivative and bovine serum albumin by fluorescence spectroscopy

The interaction between the imidazole derivative 2-(2,4-difluorophenyl)-1-phenyl-1H-imidazo[4,5-f] [1,10]phenanthroline (dfppip) and bovine serum albumin (BSA) was investigated by fluorescence and UV-vis absorbance spectroscopy. From the experimental results, it was found that the imidazole derivative has strong ability to quench the intrinsic fluorescence of BSA by forming complexes. Electrostatic interactions play an important role to stabilize the complex. The binding constants and the number of binding sites have been determined in detail. The distance (r) between the donor and the acceptor was obtained according to fluorescence resonance energy transfer (FRET). Conformational changes of BSA were observed from synchronous fluorescence spectroscopy. The effect of metal ions such as Cu2+, Zn2+, Ca2+, Mg2+, Ni2+, Co2+ and Fe2+ on the binding constants between the imidazole derivative and BSA were also studied. (C) 2011 Elsevier B.V.

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.

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.

Synthesis and biological activity of two oxireno-azecin-imidazole derivatives on perfusion pressure via guanylate cyclase inhibition

Some drugs have used in the treatment of heart failure; however, several of these drugs can produce secondary effects such as arrhythmia, hypotension and others. Therefore, the objective of this study was to synthesize two oxireno-azecin-imidazole derivatives (compounds 13 and 14) from two estradiol and estrone analogs through a series of reactions which involving; a) addition; b) acetylation; c) epoxidation; d) formation of two azecine derivatives; e) removal of silyl fragment of the azecines with hydrofluoric acid. Additionally, these compounds were confirmed by NMR spectroscopic data. Then, biological activity of the oxireno-diazepam-imidazole derivatives against perfusion pressure was evaluate in an isolated rat heart model, using the BAY-41-2272 (guanylate cyclase agonist), NS-2028 (guanylate cyclase inhibitor) and nifedipine (calcium channel antagonist) as controls. The results indicate that compounds 13 and 14 increased the perfusion pressure in the absence or presence of BAY-41-2272 and NS-2028; however, this effect was inhibited by nifedipine. These data indicate that compounds 13 and 14 could have a dual effect on perfusion pressure through guanylate cyclase inhibition and calcium channel type-L activation.

Utilization of cyanothioformamides in the syntheses of various types of imidazole derivatives

When, cyanothioformamide derivatives are reacted with certain electrophiles, they produce imidazole, oxazole, thiazole, 2,5-thiadiazole, bis-imidazole and bis-oxazole derivatives; while the reaction with certain nucleophiles furnish benzoxazole, quinaolinone, triazole, bis-triazole, benzoxazinethione and 1,3,4-thiadiazole derivatives. Imidazolidineiminothione derivatives were obtained by ring closure reaction of cyanothioformamide derivatives with isocyanates. These reactions give rise to imidazole derivatives that contain adjacent thione and imino functional groups in the positions 4 and 5 which are reactive in numbers of subsequent ring closure reactions. These compounds find applications as medicinal and pharmacological agents.
