Studies on interaction between an imidazole derivative and bovine serum by spectral methods

The interaction between a trifluoromethyl substituted imidazole derivative 2-(4-(trifluorometh yl)phenyl)-1-phenyl-1H-imidazo[4,5-f] [1,10] phenanthroline (tfmppip) and bovine serum albumin (BSA) was investigated by solution spectral studies. The observed experimental result shows that the imidazole derivative has strong ability to quench the fluorescence of BSA by forming complex which is stabilized by electrostatic interactions. The effective quenching constants (k(sv)) were 2.79 x 10(4), 2.51 x 10(4), and 2.32 x 10(4) at 301, 310 and 318 K respectively. The Stern-Volmer quenching constant (K-sv), binding site number (n), apparent binding constant (K-A) and corresponding thermodynamic parameters (Delta G, Delta H and Delta S) were calculated. The distance between the donor (BSA) and acceptor (tfmppip) was obtained according to fluorescence resonance energy transfer (FRET). Conformational changes of BSA were observed from synchronous fluorescence technique. 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) 2012 Elsevier B.V.

One-Pot Synthesis of 2,4,5-Triphenyl Imidazoles from 1,2-Diols as Key Reagents

A simple one-pot procedure for the preparation of 2,4,5-triphenyl imidazole derivatives is presented. The procedure involves the lead tetraacetate oxidation of 1,2-diols to give aldehydes in situ, which then undergo a three-component reaction with benzil and ammonium acetate to yield the imidazole derivatives.

Phosphine-free palladium-catalysed direct 5-arylation of imidazole derivatives at low catalyst loading

The regioselective 5-arylation of imidazole derivatives with aryl bromides using a low loading of a phosphine-free palladium catalyst gives a simple and economic access to the corresponding 5-arylimidazoles. The choice of the base and of the solvent was found to be crucial to form these products in high yields. Using KOAc as the base, DMAc as the solvent and only 0.5-0.01 mol % Pd(OAc)(2) as the catalyst, the target products were obtained in moderate to good yields with a wide variety of aryl bromides. Substituents Such as fluoro, trifluoromethyl, formyl, acetyl, propionyl, ester OF nitrile on the aryl bromide are tolerated. Sterically congested aryl bromides or heteroaryl bromides can also be employed. The nature of the substituents on the imidazole derivative has an important influence on the yields.

Synthesis and biological evaluation of 3-(azolylmethyl)-1H-indoles and 3-(alpha-azolylbenzyl)-1H-indoles as selective aromatase inhibitors

This present study identifies a number of azolyl-substituted indoles as potent inhibitors of aromatase. In the sub-series of 3-(azolylmethyl)-1H-indoles, four imidazole derivatives and their triazole analogues were tested. Imidazole derivatives 11 and 14 in which the benzyl moiety was substituted by 2-chloro and 4-cyano groups, respectively, were the most active, with IC50 values ranging between 0.054 and 0.050 mu M. In the other sub-series, eight 3-(alpha-azolylbenzyl)-1H-indoles were prepared and tested. Compound 30, the N-ethyl imidazole derivative, proved to be an aromatase inhibitor, showing an IC50 value of 0.052 mu M. All target compounds were further evaluated against 17 alpha-hydroxylase/C17,20-lyase to determine their selectivity profile.

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)

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.

Antioxidant potential and antimicrobial screening of some novel imidazole derivatives: greenway efficient one pot synthesis

A series of substituted imidazoles have been synthesized under solvent-free condition by grinding 1,2-diketone, aromatic aldehyde, and ammonium acetate in the presence of molecular iodine as the catalyst. The short reaction time and easy workup make this protocol practically and economically attractive and are characterized by NMR spectra, X-ray, mass, and CHN analysis. Their antioxidant potential were evaluated using different in vitro antioxidant models namely, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical, superoxide anion, and hydroxyl radical scavenging activities. Their antibacterial screening against Staphylococcus aureus, Escherichia coli, and Klbesiella pneumoniae and antifungal activity against Aspergillus niger, Aspergillus flavus, and Candida-6 were also evaluated. Among all, dimethoxyphenyl substituent at N3 of the imidazole derivatives exhibited the highest hydroxy and superoxide anion radical scavenging activities, whereas dimethoxyphenyl substituent at N3 and fluorophenyl at C2 of the imidazole derivatives exhibited the highest DPPH radical scavenging activity.
