Synthesis, antioxidant and alpha-amylase inhibition activity of naphthalene-containing 2,4,5-trisubstituted imidazole derivatives

A series of naphthalene ring containing 2,4,5-trisubstituted imidazole derivatives (2a-2l) were synthesized using one-pot multicomponent reaction. The reactions were carried out using naphthaldehyde and substituted benzil in the presence of ammonium acetate in acetic acid media. All newly synthesized imidazole derivatives were characterized by FT-IR, 1H NMR, 13C NMR and mass spectral analysis. Newly synthesized imidazole derivatives were screened for their in-vitro antioxidant activity by DPPH free radical scavenging assay method and alpha-amylase inhibition activity by DNS method. All the compounds showed excellent alpha-amylase activity at 10, 50 and 100 mu g/mL and compounds 2d, 2g, 2k exhibited good antioxidant activity.Graphic abstractA series of naphthalene ring containing 2,4,5-trisubstituted imidazole derivatives (2a-2l) were synthesized through one-pot multicomponent reaction using naphthaldehyde, substituted benzil and ammonium acetate in acetic acid medium with good yield.

Electrochemical and Theoretical Study of Imidazole Derivative as Effective Corrosion Inhibitor for Aluminium

The corrosion inhibition performance of 2-styryl-1,8-dihydro-1,3,8-triaza-cyclopentaindene (IIZ) on Aluminium in 1M HCl was investigated by electrochemical impedance spectroscopy (EIS), Potentiodynamic polarization, scanning electron microscopy (SEM), atomic force microscopy (AFM), and quantum chemical techniques. Potentiodynamic polarization study confirmed that IIZ is mixed type inhibitor with cathodic predominance. SEM and AFM confirm the formation of an adsorption film on the aluminium surface. Quantum chemical study reveals that protonated IIZ interacts more than neutral IIZ. The theoretical data obtained are in agreement with experimental results.

Synthesis, Crystal Structure, Kamlet-Taft and Catalan Solvatochromic Analysis of Novel Imidazole Derivatives

Novel imidazole derivatives were synthesized and its crystal structure has been studied by single crystal XRD analysis. The photophysical properties of these imidazole derivatives were studied in several solvents, which include a wide range of apolar, polar and protic media. The observed lower fluorescence quantum yield may be due to an increase in the non-radiative deactivation rate constant. This is attributed to a loss of planarity in the excited state provided by the non co-planarity of the aryl rings attached to C(2) and N(1) atoms 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. The highest fluorescence quantum yield of the imidazole derivatives are observed in polar media.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 60-56-0. Computed Properties of C4H6N2S.

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.

Fast and accurate predictions of heat of formation by G4MP2-SFM parameterization scheme: An application to imidazole derivatives

We proposed a new parameterization scheme, G4MP2-SFM, for the prediction of heat of formation by combining SFM (Systematic Fragmentation Method) and high accuracy G4MP2 theories. In an application to imidazole derivatives, we found that the overall MAD and RMSD of the particular G4MP2-SFM(opt) are 1.9 and 2.2 kcal/mol, respectively, demonstrating its high prediction accuracy. In addition, our parameterization scheme replaces the ab initio computations with a set of simple arithmetic, allowing fast predictions. Our new computational scheme can be of practical use in high throughput search for new high energy materials. (C) 2014 Elsevier B. V. All rights reserved.
