SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL EVALUATION OF 1H-SUBSTITUTED 2, 4, 5-TRIPHENYL IMIDAZOLE DERIVATIVES

On the basis of various literature survey, imidazole derivatives show various activity such as antimicrobial, anti-inflammatory, analgesic, antitubercular, anticancer etc. The possible improvements in the activity can be further achieved by slight modifications in the substituents on the basic imidazole nucleus. Thus imidazole offers better pharmacodynamic characteristics. Furthermore, some imidazole drugs, at high concentrations, could exert direct inhibitory effects on membranes, without interference with sterols and sterol esters. Various recent new drugs developments in imidazole derivatives show better effect and less toxicity. Prompted by the broad spectrum activities of 2, 4, 5-triphenylimidazole derivatives, it was decided to synthesize various 2, 4, 5-triphenyl-1-substituted imidazoles and to evaluate them for their biological activities.

Remarkable rate acceleration of water-promoted nucleophilic substitution of Baylis-Hillman acetate: a facile and highly efficient synthesis of N-substituted imidazole

Without additional reagents, the Baylis-Hillman acetates 2 underwent nucleophilic Substitution reaction with imidazole readily in aqueous THF solution to afford the corresponding N-substituted imidazole derivatives 3 in good to excellent yields. Moreover, the reaction between the in situ generated DABCO salt of Baylis-Hillinan acetates 4 and imidazole occurs in aqueous THF providing the S(N)2 type products 5. The simpler operational procedure, better stereoselectivity and higher efficiency over conventional method make the present protocol practical for the preparation of imidazole derivatives.

A Combined Experimental and DFT-TDDFT Study of the Excited-State Intramolecular Proton Transfer (ESIPT) of 2-(2′-Hydroxyphenyl) Imidazole Derivatives

We report a combined experimental and computational study of the effect of electron donor and acceptor groups on the excited state intramolecular proton transfer of 2-(2′-hydroxyphenyl) imidazole derivatives in solvents of different polarities. The changes in fluorescence properties, electronic transitions and energy levels are analyzed and discussed. The study was complemented using the Density Functional Theory (DFT)-Time Dependent DFT [B3LYP/6-31G(d)] computations. The calculated absorption and emission spectra of the imidazole derivatives are in good agreement with the experiments, thus allowing an assignment of the UV-vis spectra.

Evaluation of non-toxic corrosion inhibitors for copper in sulphuric acid

The aim of this paper is to study influence of the molecular structure on the inhibiting properties of organic compounds in corrosion processes in acid media. The inhibiting efficiency of non-toxic imidazole derivatives on copper corrosion in sulphuric acid is investigated. The investigation is performed using electrochemical methods of potentiodynamic polarisation as well as gravimetric measurements. The results of the investigation show that the inhibiting properties of substituted imidazoles depend on molecular structure. The best protection (93%) is obtained by adding a phenyl ring to the imidazole structure. The values of standard free energies of adsorption, as calculated from the Freundlich isotherm, indicate that in the presence of sulphuric acid imidazole derivatives adsorb on copper by a physisorption-based mechanism.

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.

Reaction of imidazole derivatives with trifluoromethylated arylacetylenes

The nucleophilic addition of imidazole derivatives to trifluoromethylated acetylenes was studied. Unpredictable regioselectivity of the reaction was observed to yield both beta- and alpha-addition products. The reaction is 100% stereoselective to give the corresponding adducts as a Z-isomers only. The observed regioselectivity is discussed in terms of polarization of triple bond using experimental and calculated data. (C) 2016 Elsevier B.V. All rights reserved.

Ring closing metathesis reactions of imidazole derivatives

A series of diene substituted imidazole derivatives has been prepared from the corresponding haloimidazoles via halogen-magnesium exchange and electrophile quench. These derivatives were explored as susbstrates in a ring closing metathesis reaction, which was successful if the imidazolium ion was used. In addition, one successful example of a ring closing metathesis reaction of an enyne derivative was performed, with the resulting diene successfully engaging in a Diels-Alder reaction.

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.
