Electrochemical, surface and quantum chemical studies of novel imidazole derivatives as corrosion inhibitors for J55 steel in sweet corrosive environment

The corrosion inhibition performance of three novel imidazole derivatives namely 2-(4-methoxyphenyl)4,5-diphenyl-imidazole (M-1), 4,5-diphenyl-2-(p-tolyl)-imidazole (M-2) and 2-(4-nitrophenyl)-4,5-diphenyl-imidazole (M-3) for J55 steel in CO2 saturated brine solution was studied by weight loss method, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning electrochemical microscopy (SECM), contact angle, scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and quantum chemical calculation. M-1 exhibited the best inhibition efficiency of 93% at 400 mg/L concentration. The adsorption of the imidazole derivatives obeyed the Langmuir adsorption isotherm. Contact angle measurement reveals the hydrophobic nature of J55 steel in presence of inhibitors. Quantum chemical calculation well supports the experimental results. (C) 2017 Elsevier B.V.

A convenient method for the preparation of symmetric and unsymmetric bisimidazole derivatives was established. The symmetric bisimidazolylmethane derivatives 1a-9a was prepared with 2-substituted imidazole derivatives 1-9 as reaction materials. However, the symmetric and unsymmetric bisimidazolylmethane derivatives 10a-12a and 10b-12b was obtained, respectively. With 4-position with the azo-groups imidazole derivatives 10-12 were used as reaction materials. All these compounds have been structurally characterized by the NMR, ESI-MS, and EA. And 8a and 12a were also characterized by the X-ray single crystal diffusion.

COUPLING OF NU(NH…N) VIBRATIONS WITH THE GAMMA(NH…N) OVERTONE IN SOLID IMIDAZOLE DERIVATIVES

The IR spectra of a number of imidazole derivatives were studied in the solid state at room and liquid nitrogen temperatures. The bands ascribed to stretching and out-of-plane deformation vibrations of NH groups involved in strong NH…N hydrogen bonds were analysed. The energy of this bond reflected in the position of the nu(NH…N) band changes over a broad range so that it was possible to investigate band shaping due to the overlap with the overtone band of the gamma(NH…N) mode. The correlation between the gamma(NH…N) and nu(NH…) frequencies shows that the gamma(NH…N) value for strong NH…N bridges only slightly depends on nu(NH…N).

QSAR study for classes with a broad range of biological activity using electronegativity descriptors for OMO-UMO quantum states. Clotrimazole imidazole derivatives with antiftingal activity

The class of clotrimazole imidazole derivatives having a broad spectrum of antimycotic activity has been studied using fingerprint descriptors based on electronegativity, of the occupied molecular orbitals (OMO) and unoccupied molecular orbitals (UMO). The Hansch equation Kd = a(0) + a(I)X(I), where X, = OMO / UMO electronegativity allows us to identify the nature of the atoms involved in ligand (drug)-receptor interactions, as well as the nature of those interactions.

EFFECTS OF IMIDAZOLE DERIVATIVES ON CYTOCHROMES-P450 FROM HUMAN HEPATOCYTES IN PRIMARY CULTURE

The expression of several forms of cytochrome P450 including P450 1A2, 2D6, 2E1 and 3A was investigated in human hepatocytes maintained in primary culture for 96 h in the absence or presence of 50-mu-M of various imidazole derivatives. These included ketoconazole, clotrimazole, miconazole, fluconazole, secnidazole and metronidazole. In addition, the typical inducers rifampicin and beta-naphthoflavone were used for comparison. Western and Northern blot analysis of microsomes and RNA prepared from these cultures as well as de novo synthesis experiments revealed that, among the imidazole derivatives tested, only clotrimazole was a strong rifampicin-like inducer of P450 3A. The expression of the other forms of P450 tested was not affected by the treatments. Analysis of the inhibition of 13 monoxygenase activities, including ethoxyresorufin and phenacetin O-deethylases, coumarin 7-alpha-, lauric acid 11- and 12-, mephenytoin 4-, debrisoquin 4-, and aniline hydroxylases, benzphetamine, aminopyrine, mephenytoin and erythromycin demethylases, and cyclosporin oxidase (representative of 10 different forms of P450 in human liver microsomes) revealed that ketoconazole was a strong and selective in vitro inhibitor of P450 3A (cyclosporin oxidase) with a K(i) < 1-mu-M. Clotrimazole and miconazole were also strong inhibitors of P450 3A-mediated activities in contrast to the other imidazole derivatives.

Mutagenic activities of ten imidazole derivatives in Salmonella typhimurium

Ten imidazole derivatives were tested for mutagenicity in Salmonella typhimurium strains TA98 and TA100 both in the absence and presence of metabolic activation by the microsomal fraction S9 mix. In a general manner, derivatives tested exhibited a greater mutagenic activity in the TA100 strain comparing to the responses in TA 98. In the standard plate incorporation assay, 8 of these substances (80%) were found to be mutagenic for at least one of the two strains in the presence or absence of metabolic activation. Two compounds showed positive results in TA98 and 6 compounds were also mutagenic in TA100 without S9. In the presence of S9 mix, all of the 10 substances were non-mutagenic in TA98, whereas 4 compounds were positive in TA100. The results suggested the mutagenic potentials of the imidazole derivatives particularly inducing the reversion of base-pair substitutions. According to the structure-activity relationships phenyl groups in position 2 with different substituents can confer the mutagenic activity of the tested compounds. Methyl groups in different positions of these phenyl substituents can cause different types of mutations. This mutagenic effect is observed more clearly when the phenyl group is inhibited with a nitro group.

Green Synthesis of Imidazole Derivatives via Fe3O4-MNPs as Reusable Catalyst

In this research, a one-pot, efficient, and high yielding procedure for the synthesis of imidazole derivatives is investigated. The procedure was carried out via multicomponent reaction of isothiocyanate, alkyl bromides, N-methylimidazole, and triphenylphosphine in the presence of magnetic iron oxide nanoparticles (Fe3O4-MNPs) as reusable catalyst under solvent-free conditions at 50 degrees C. Also, Fe3O4-MNPs were produced using green synthetic method by reduction of ferric chloride solution with Clover Leaf water extract. The nanoparticles generated using this procedure can potentially be important in different purposes such as organic synthesis. Easy, simple, rapid, and clean procedures for the synthesis of imidazole derivatives are the advantages of this study.

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 3543-73-5. SDS of cas: 3543-73-5.
