Clay-Supported 2-Phenyl-1H-Imidazole Derivatives for Heterogeneous Catalysis of Henry Reaction

Six derivatives (1-6) of 2-phenyl-1H-imidazole were tested as catalysts of Henry reaction. Three new (4-6) 2-phenyl-1H-imidazole derivatives, differently substituted (thio)ureas, were synthesized and determined by H-1 NMR and IR spectroscopy and elemental analysis. Two types of catalysis, homogeneous and heterogeneous, were examined and compared. Clay minerals Ca-MMT and Cu-MMT were used as solid supports for heterogeneous catalysis. The best results were obtained using compound 2 under conditions of heterogeneous method D from the point of view of yield and reaction time.

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 3543-72-4. HPLC of Formula: C14H17N3O4.

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.

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.

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.

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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3543-72-4 is helpful to your research. HPLC of Formula: C14H17N3O4.

Optoelectronic features of Y-shaped push-pull molecules based on imidazole

The paper involves organic light-emitting diodes fabricated with application of Y-shaped push-pull imidazole derivatives (chromophores) blended with poly(N-vinylcarbazole) as an organic active materials. The absorbance, photoluminescence and electroluminescence spectra of chromophores as well as electroluminescence-voltage, current-voltage and electroluminescence-voltage of the manufactured devices are presented. All investigated imidazole derivatives dissolved in tetrahydrofuran exhibited strong luminescence. The investigated organic light-emitting diodes exhibit red-shift in the main spectral maxima from 520 to 598 nm for photoluminescence and from 535 to 590 nm for electroluminescence depending on the type of imidazole derivative used. The electroluminescence spectra also proved to be very stable over the luminance range from 700 to 1600 cd/m(2), which is the luminance used for typical lighting applications.

Practical and Efficient Synthesis of 2-Thio-imidazole Derivative-ZY12201: A Potent TGR5 Agonist

Early scalable process development for the synthesis of ZY12201, a novel TGR5 receptor agonist, as a potential clinical candidate is described. A practical, efficient, and scalable synthetic route provided ZY12201 in seven steps and 32% overall yield. The key step involves an inexpensive acetic acid-mediated cyclization of thiourea 6 for the construction of 2-thio-imidazole derivative 7. The developed process demonstrated cost-effective, high-yielding, kilogram-scalable, and environmentally friendly synthesis of ZY12201. This high-yielding route enabled us to rapidly synthesize large quantities of ZY12201 in 99% purity to support in vivo and toxicity studies.
