Fabrication of one-component epoxy resin systems using maleic acid modified imidazole derivatives

A series of maleic acid modified imidazole derivatives (IM-MA, 2MI-MA and 2EI-MA) were synthesized via the Michael addition reaction of maleic acid (MA) with imidazole (IM), 2-methylimidazole (2-MI) and 2-ethylimidazole (2-EI), respectively. H-1 nuclear magnetic resonance (NMR), Fourier Transform Infrared (FTIR) spectra and Elemental analysis (EA) were used to verify the structure of maleic acid modified imidazole derivatives. The maleic acid modified imidazole derivatives were used as latent curing agents for epoxy resin (EP). Differential scanning calorimeter (DSC) under dynamic and isothermal condition was used to study the curing behavior of the prepared EP systems. The curing reactivity of maleic acid modified imidazole derivatives were significantly suppressed, compared with the common imidazole compounds. The EP systems containing maleic acid modified imidazole derivatives possessed excellent storage stability of at room temperature, due to the electron-withdrawing effect of carboxyl reduced the nucleophilicity of imidazole ring and the intermolecular hydrogen bond formed between carboxyl and 3-position nitrogen atom further restrained the nucleophilicity of imidazole ring. What’s more, the maleic acid modified imidazole derivatives regained fast curing ability towards EP under heating condition. Taking advantage of these characteristics, the maleic acid modified imidazole derivatives were suitable for preparing one-component EP systems.

Synthesis of Imidazole-Based AIEgens with Wide Color Tunability and Exploration of their Biological Applications

Research on aggregation-induced emission (AIE) has become increasingly popular recently and various AIE luminogens (AIEgens) have been developed based on tetraphenylethene, hexaphenylsilole, distyrylanthracene, tetraphenylpyrazine, etc. However, facile tuning of the AIEgen emissions in a wide range remains challenging. Herein, a novel series of AIEgens is reported, based on imidazole-cored molecular rotors, with facile synthesis and emission colors covering the whole visible spectrum. Moreover, these imidazole derivatives exhibit biological functions unique among the AIEgens, including mitochondria-specific imaging and antifungal activity. Benefiting from the easy preparation and the tunable emission, the imidazole derivatives are expected to not only diversify the family of AIEgens but also enrich their biological applications.

Low-toxicity copper corrosion inhibitors

The efficiency of various imidazole derivatives as corrosion inhibitors for copper in hydrochloric and sulfuric acids (HCl and H2SO4) was investigated. Electrochemical measurements showed the organic compounds investigated have fairly good inhibiting properties, except for 4-methyl-5-imidazole-carbaldehyde in HCl. Protecting properties of most imidazole derivatives were close to those of commercial inhibitors for copper. Evaluation of the toxicity of the water solutions on the biological system for treatment of waste water – as measured in regard to chemical oxygen demands (COD), aerobic, and anaerobic toxicity – showed the tested inhibitors have relatively low toxicity.

One pot Pd(OAc)(2)-catalysed 2,5-diarylation of imidazoles derivatives

The regioselective 2- or 5-arylation of imidazole derivatives with aryl halides using palladium catalysts has been described in recent years; whereas the arylation at both C2 and C5 carbons of imidazoles in high yields has not been performed. We found conditions allowing the access to these 2,5-diarylimidazoles via a one pot reaction. The choice of the base was found to be crucial to obtain these products in high yields. Using CsOAc as the base, DMA as the solvent and only 2 mol % of the phosphine-free Pd(OAc)(2) the catalyst, the target 2,5-diarylated imidazoles were obtained in moderate to good yields with a wide variety of aryl bromides. Substituents such as fluoro, trifluoromethyl, formyl, acetyl, propionyl, ester, nitro or nitrile on the aryl bromide were tolerated. Sterically congested aryl bromides or heteroaryl bromides can also be employed. Surprisingly the nature of the substituent at position 1 on the imidazole derivative exhibits a huge influence on the reaction. (C) 2014 Elsevier Ltd. All rights reserved.

Synthesis of imidazole derivatives and the spectral characterization of the binding properties towards human serum albumin

Small molecular drugs that can combine with target proteins specifically, and then block relative signal pathway, finally obtain the purpose of treatment. For this reason, the synthesis of novel imidazole derivatives was described and this study explored the details of imidazole derivatives binding to human serum albumin (HSA). The data of steady-state and time-resolved fluorescence showed that the conjugation of imidazole derivatives with HSA yielded quenching by a static mechanism. Meanwhile, the number of binding sites, the binding constants, and the thermodynamic parameters were also measured; the raw data indicated that imidazole derivatives could spontaneously bind with HSA through hydrophobic interactions and hydrogen bonds which agreed well with the results from the molecular modeling study. Competitive binding experiments confirmed the location of binding. Furthermore, alteration of the secondary structure of HSA in the presence of the imidazole derivatives was tested.

Imidazole derivatives as new potent and selective 20-HETE synthase inhibitors

In a previous paper, we reported that an imidazole derivative I exhibited a potent inhibitory activity of 20-HETE synthase (1; IC50 value of 5.7 nM), but this compound also exhibited little selectivity for cytochrome P450s (CYPs). We examined some derivatives of imidazole I which had an amino group on the side chain, and found that a dimethylaminohexyloxy derivative (3g ;IC50 value of 8.8 nM) showed potent and selective inhibitory activity.

SUPERCRITICAL FLUID CHROMATOGRAPHY OF IMIDAZOLE DERIVATIVES

The aim of this work was to use SFC to separate simple, slightly basic, imidazole derivatives which are used for the synthesis of more complex molecules with therapeutic properties. Control of their purity utilizes separation techniques and this paper shows that SFC can do in comparison with LC which requires derivatization before detection and with GC where peak tailing can be a problem. Our results concern the use of sub-critical mixtures of CO2 and polar modifiers because imidazole derivatives react with neat CO2, thus failing to elute from packed columns, and are only partially resolved on capillary columns with neat N2O. Therefore, separations with CO2-alcohol-amine-water mixtures on aminopropyl-bonded silica with UV detection are discussed. The resolution and sensitivity limits allow real sample analysis within a very short time.
