Biological evaluation of imidazole derivatives as inhibitors of hydroperoxide lyase, a key enzyme in plant volatile biosynthesis

Fatty acid hydroperoxide lyase (HPL) is a key enzyme in the biosynthesis of plant volatiles involved in defense responses to mechanical or herbivore-induced wounding. We report here the synthesis of imidazole derivatives and their inhibitory activities on the tomato 13-HPL subfamily. Among 1l newly synthesized compounds, we found that 1-[2-benzyloxy-2-(2,4-dichlorophenyl)ethyl]-1H-imidazole (3) exhibits inhibitory activity against recombinant 13-HPL with an IC(50) value of approximately 39 mu M. Optical difference spectroscopy analysis of compound 3 and HPL interaction indicated that this compound induces a type II binding spectra with a K(d) value of approximately 13.5 mu M.

Photophysical studies of fused phenanthrimidazole derivatives as versatile pi-conjugated systems for potential NLO applications

Two new heterocyclic imidazole derivatives consists of pi-conjugated system attached to a phenanthrimidazole moiety have been synthesized in moderate yield by the condensation of 1,10-phenanthroline-5,6-dione with substituted aromatic aldehydes and 4-methoxyaniline in the presence of ammonium acetate in ethanol medium. The photophysical properties of these imidazole derivatives were studied in several solvents. These derivatives were evaluated concerning their solvatochromic properties and molecular optical nonlinearities. Their electric dipole moment (mu) and hyperpolarizability (beta) have been calculated theoretically and the results indicate that the extension of the pi-framework of the ligands has an effect on the NLO properties of these imidazole derivatives. The non-zero tensor components of these imidazole derivatives reveal that they possess potent non-linear optical (NLO) behavior. The energies of the HOMO and LUMO levels and the molecular electrostatic potential (MEP) energy surface studies have exploited the existence of intramolecular charge transfer (ICT) within the molecule.

Development and characterization of imidazole derivative cured bisphenol A epoxy materials for flip-chip underfill applications

This paper is targeted to provide underfill manufacturers and electronic packaging companies with general information about imidazole derivative cured bisphenol A epoxy materials. Four selected imidazole derivatives and one bisphenol A epoxy resin were investigated in this paper. Differential Scanning calorimetry (DSC) was used to study the curing kinetics of the prepared formulations and glass transition temperature (Tg) of the cured formulation. Thermo-Mechanical Analyzer (TMA) was used to investigate the heat flex temperature and coefficient of thermal expansion (CTE). Dynamic-Mechanical Analyzer (DMA) was used to measure the storage modulus (E’) and cross-linking density (rho) at the temperature range from 25 degrees C to 250 degrees C of the cured materials. A rheometer was used to investigate the viscosity (eta) of these formulations. The effects of the curing agent type and concentration on the curing kinetics, Tg, CTE, E’, rho, and eta were then investigated. The correlation between CTE (above Tg) and crosslinking density was examined and discussed.

X-ray Crystal Structure, Geometric Isomerism, and Antimicrobial Activity of New Copper(II) Carboxylate Complexes with Imidazole Derivatives

Five new copper(II) acrylate complexes (acr is the acrylate anion: C3H3O2) with imidazole derivatives (2-methylimidazole/2-MeIm, 5-methylimidazole/5-MeIm, 2-ethylimidazole/2-EtIm) of type: cis-[Cu(2-RIm)(2)(acr)(2)]xH(2)O ((1): R = -CH3, x = 2; (4): R = -CH2-CH3, x = 0), trans-[Cu(2-RIm)(2)(acr)(2)] ((2): R = -CH3; (5): R = -CH2-CH3) and trans-[Cu(5-RIm)(2)(acr)(2)] ((3): R = -CH3) have been prepared and characterized by elemental analysis, Fourier Transform Infrared spectrometry (FTIR), Electron Paramagnetic Resonance (EPR), electronic reflectance spectroscopy, scanning electron microscopy, and mass spectrometry. The single crystal X-ray diffraction study of complexes (2) and (5) reveals that the copper(II) ion is located on an inversion center and show elongated octahedral geometry completed by two coplanar bidentate acrylates and two unidentate imidazole derivatives displayed in trans positions. For complex (4) the single crystal X-ray diffraction shows that the copper(II) ion is in a distorted octahedral environment which can be easily confused with a trigonal prism completed by two bidentate acrylates and two unidentate imidazole derivatives displayed in cis positions. These results indicate the fact that complexes (4) and (5) are the geometric isomers of the same compound bis(acrylate)-bis(2-ethylimidazole)-copper(II). Complexes (1) and (2), as well as (4) and (5), were produced simultaneously in the reaction of the corresponding copper(II) acrylate with imidazole derivatives in methanol solution. Furthermore, in order to be able to formulate potential applications of the obtained compounds, our next goal was to investigate the in vitro antimicrobial activity of the synthesized complexes against Gram-positive and Gram-negative bacteria, as well as fungal strains, of both clinical and ecological importance (biodeterioration of historical buildings). The trans isomers (2) and (5), followed by (4) have shown the broadest range of antimicrobial activity. In case of (1) and (2) isomers, the trans isomer (2) was significantly more active than cis (1), while the cis isomer (4) proved to be more active than trans (5). Taken together, the biological evaluation results indicate that the trans (2) was the most active complex, demonstrating its potential for the development of novel antimicrobial agents, with potential applications in the biomedical and restoration of architectural monuments fields.
